How To Safely Dispose Of Old Gasoline From Your Lawn Mower

Is your lawn mower not starting properly after sitting all winter? Old gasoline may be the culprit. Read our complete guide to safely draining, storing, and disposing of bad lawn mower gas so you can get your engine running smoothly again this mowing season.

Assessing If Your Lawn Mower Gas Is Old Or Bad

If you didn’t run your lawn mower dry before packing it away at the end of last mowing season, you may have some old gas sitting in its tank. Before trying to start up your mower after months of non-use, it’s wise to check whether the gas is still good to use or has degraded. Nobody wants to ruin their mower’s carburetor before the first spring grass cutting!

Here are some tips for identifying if the gasoline in your mower has gone bad while in storage over the winter.

Signs Gas May Be Old or Contaminated

There are a few telltale signs that the gas in your mower may have gone bad:

• Discoloration – Fresh gas usually has a clear, light yellow or light brown appearance. Old gas often takes on a much darker, reddish-brown, orange or even blackish color. This is a result of oxidation and evaporation degrading the fuel over time. Dark gas likely won’t combust well.
• Strange or sour smell – Gas that has gone bad gives off a sour, pungent odor rather than the strong chemical smell of fresh gas. Take a whiff of the gas coming out of your mower’s tank – if it smells off, the gas is probably bad.
• Particles or debris – Old gas that has degraded can contain floating debris, dirt particles, and gummy residues. These contaminants can clog up carburetors and fuel lines. Check for any visible particles or cloudiness in the gas.
• Separation – Gas can separate into layers when it sits for too long. You may see a watery layer on the bottom with discolored fuel on top. This separation makes the gas unusable in engines.
• Algae growth – If water has gotten into the gas by condensation, algae can actually start to grow inside the tank. Look for greenish slimy strands – a sure sign the gas has been contaminated.

If you notice any of these warning signs, your mower’s gas has likely gone bad and should not be used. Next, you can confirm with a quick comparison test.

Testing Gas in a Clear Container

The best way to assess old gas from your mower is to drain some into a clear glass jar or bottle so you can examine its appearance.

Here’s how:

• Use a small hose or turkey baster to siphon some gas from the mower tank into the clear container. Take gas from the bottom of the tank where condensation collects.
• If needed, gently swirl the container to mix up the gas and see if any debris floats to the top.
• Inspect the color and smell of the gas:
• Fresh gas will look clear yellow, with a strong chemical odor.
• Old gas will appear discolored, with a sour smell.
• Watch for separation of water or solids settling at the bottom.
• Tip the container to see if the gas flows well or has become thicker and more viscous.

This visual inspection will confirm if the gas is contaminated and should be disposed of. Now for the final check…

Comparing to Fresh Gas

For the best determination, pour some fresh gasoline from a new gas can into a second clear container. Put the two samples side by side for comparison.

• The fresh gas should have a light color and strong odor, while the old gas will look darker with an unpleasant smell.
• Swirl both containers and observe the behavior of the fuel – the fresh gas should move freely, while old gas may appear thicker and leave residue on the container walls.
• Check for separation or debris in the old gas sample that is not present in the fresh gasoline.

The differences between the two samples should be obvious. If your mower gas looks more like the bad sample, then you’ll want to dispose of it properly before running the mower.

With these simple tests, you can determine if the gasoline left in your lawn mower has degraded and needs to be drained. Never try starting your mower with contaminated or separated gas that has visible particles – you’ll regret it later when the engine starts sputtering from clogged fuel lines. Save yourself the cleaning headache by assessing the gas first and disposing of any that has gone bad over time. Your mower will thank you!

Now that you know how to identify old, bad gas, it’s time to move on to the next step – draining it safely from your lawn mower in preparation for adding fresh fuel. We’ll cover that process next. Let’s keep going and get your mower’s engine revved up and ready for spring.

Draining Old Gasoline From The Lawn Mower

So you’ve determined the gas in your mower is degraded and needs to go. Here’s how to safely drain the old fuel from the tank and components. Proper removal of bad gas gets the mower ready for fresh fuel and prevents potential engine damage.

Running Mower Dry Before Storage

The best way to avoid having to drain old gas is to avoid leaving it in the mower in the first place.

Before packing up your mower at the end of mowing season, add fuel stabilizer to the gas tank and run the mower until the tank is empty. Letting the engine run dry ensures no leftover gas remains to go bad over months of storage.

However, if you already have old gas sitting in the mower, here are some tips for getting it out:

Using a Siphon or Pump to Remove Gas

One of the easiest ways to empty the mower’s fuel tank is using a siphon hose or mechanical pump.

You’ll need:

• Gas can or storage container
• Siphon hose or mechanical pump
• Gloves & safety glasses

Steps:

1. Before starting, put on gloves and safety glasses. Spilled gasoline can irritate skin and eyes.
2. Connect the siphon hose securely to the empty gas can. For a pump, insert the intake tube into the mower tank.
3. Squeeze the siphon bulb repeatedly or operate the pump until gas starts flowing out.
4. Drain as much gas as possible into the can – keep the intake end fully submerged.
5. When gas stops flowing, disconnect the siphon or pump.
6. Seal the gas can and handle it carefully to avoid spills.

Tip: Use a clear gas hose so you can see when gas stops flowing.

Siphons and pumps allow quick, easy removal of old gas without having to dismantle the mower. Just be sure to work outdoors only, avoid spills, and seal the used fuel container.

Detaching Fuel Line Into Gas Can

On some mowers, you can disconnect the fuel line where it attaches to the carburetor.

Supplies needed:

• Gas can
• Pliers or wrench
• Gloves & safety glasses

Steps:

1. Locate the fuel line connecting to the carburetor – it’s typically a rubber or plastic hose.
2. Slip on gloves and eye protection before handling gas components.
3. Pinch off the fuel line if possible, then disconnect it from the carburetor using pliers or a wrench.
4. Lower the disconnected fuel line into the gas can to drain the tank.
5. When gas stops flowing, reconnect the fuel line to the carburetor.
6. Wipe up any drips and wash hands after handling gasoline.

Detaching the fuel line directly empties the tank without added siphons or pumps. Just be prepared for some gasoline dripping.

Draining Carburetor Bowl

The carburetor bowl also holds a small amount of gas that can go bad. Removing it requires some disassembly.

Needed:

• Socket set
• Gas can
• Gloves & safety glasses
• Clean rag

Steps:

1. Consult mower manual for carburetor model and bowl bolt size.
2. Disconnect spark plug wire. Power must be cut off before disassembling carb.
3. Use correct socket size to unscrew bowl retaining bolt and remove bowl.
4. Have gas can ready to catch drained fuel. Old gas may also spill from feed tube.
5. When bowl is empty, clean with rag. Inspect float, needle valve for issues.
6. Replace carb bowl and retaining bolt. Snug bolt down just until carb sealed.
7. Reconnect spark plug wire when done.

Draining the carburetor removes old gas from the engine fuel supply. Take precautions to avoid spills and parts damage during disassembly.

Pro Tip: Spray carburetor cleaner into the empty bowl to clean out gunk and residues. Just avoid soaking any rubber/plastic parts.

Removing Remaining Gas

Even after draining the tank, fuel lines, and carburetor, a little old gas may remain:

• Run the mower until it stalls to burn up residual fuel in carburetor.
• Tip mower back and forth to allow gas to flow into tank outlet. Drain again.
• Absorbent pads can soak up gas remaining in the tank. Dispose of properly after use.

The goal is to remove as much degraded gas as possible before adding fresh fuel. With the old gas gone, you can inspect the fuel system components and service if needed before the mowing season. Prevention is the best medicine!

Now let’s move on to the crucial step of storing the old gasoline safely. We don’t want to create a hazard or disposal issue by having open containers of volatile, flammable liquid sitting around. Proper storage containers and handling procedures are essential – read on to learn more.

Storing Old Gasoline Properly Before Disposal

You’ve successfully drained the old degraded gasoline from your lawn mower’s tank and components. But now you’re left with a container of volatile, flammable liquid that you’ll need to properly dispose of. To avoid turning your garage into a hazmat zone, follow these guidelines for safe storage until you can take that old gas to the disposal site.

Use Only Approved Gas Containers

Never store old gasoline in food or drink containers that someone might consume from accidentally! Instead, put the gas in an approved fuel canister made specifically for gasoline storage and transport. Look for these features in a good gas can:

• Government certification – Containers should meet EPA and state requirements for transporting hazardous liquids like gasoline. They will be marked as such.
• Flame arrestor – Metal mesh in the spout prevents fire flashback into the can. This safety device is a must-have.
• Leakproof seal – A tight sealing cap keeps fumes contained and prevents spills/leaks.
• Static grounding – Containers made of metal or conductive plastic prevent static charge buildup.
• Pressure relief valve – Allows gas vapors to vent if over-pressurized, avoiding rupture.
• ** Sturdy material** – Thick metal or durable plastic stands up to impacts if dropped or tipped over.

Look for gas cans and tanks made by reputable brands that include these protective features. And check that the container is in good condition with no damage, cracks, or rust.

Fill Containers Only 95% Full

Don’t top off the gas container all the way to the brim! Leave around 5% empty space at the top for expansion and to reduce risk of spills:

• Gasoline expands as temperatures rise, increasing pressure inside a completely filled container. This could cause leaks.
• Leaving room at the top allows space for vapors to accumulate so you don’t spill liquid gas when opening the can.
• A bit of empty space lets you swirl or shake the container to mix stabilizers without spilling.

Only fill portable gas cans to around 95% capacity. For larger tanks, fill to the base of the neck opening. This headspace reduces chances of overflow incidents while handling and transporting gasoline.

Seal Gas Containers Tightly

Once filled, immediately seal the container tightly so no vapors escape:

• Screw on the cap until it won’t turn any further to ensure a tight seal. Avoid over-tightening plastic caps.
• If using a utility jug with a spout, clamp the spout downward into the locked position.
• Check that any vents or pressure relieve valves have closed properly.
• Test seal by tilting container slowly – no liquid or fumes should leak out.

Keep containers upright while transporting to prevent spills through vents. And double check the tightness of the seals before moving containers. Preventing gasoline vapor release is a top priority for safe handling.

Transport Gas Containers in Second Containment

Even with the best gas cans, there’s always a small chance of leaks and spills while moving containers. That’s why secondary containment is recommended during transport:

• Place smaller gas cans upright inside a plastic bin or tub to catch any leaks.
• For larger cans, use an open-top dolly designed for gas can movement.
• Never transport loose gas cans in the trunk – vapors could enter passenger area.
• Avoid transporting gas containers in hot vehicle interiors where temperatures rise.
• Go directly to the disposal site; don’t leave filled cans in your vehicle unattended.

Secondary containment like spillproof tubs provides an added layer of protection against gasoline releases inside your vehicle.

Tip: Write “GASOLINE” clearly on the outside of containers so contents are obvious. Use resealable freezer bags to prevent paper labels being dissolved by spills.

Other Safety Measures

• Store gas containers away from ignition sources like pilot lights. Vapors are flammable.
• Keep gasoline locked up and away from children/pets. Use child safety locks if needed.
• Avoid placing containers near drains. Gas could flow into waterways if spilled.
• Wear gloves when handling containers to prevent skin exposure. Wash hands after.

By using proper vessels, filling them correctly, and taking containment precautions, you can safely store old gasoline until it can be disposed. Never keep gas in food/drink bottles or overfill containers – that’s asking for trouble. Following these tips minimizes the risks of fire, contamination, and health effects from improper gas storage.

Now that you’re an expert in safe gasoline handling, it’s time to find out where you can actually take old gas to be disposed of properly. Read on to learn how to locate approved hazardous waste facilities or events in your area. Let’s go give that degraded fuel a proper send-off!

Finding Nearby Locations To Dispose Of Gasoline

Now that you’ve got old, degraded gasoline safely contained, it’s time to locate where you can properly dispose of it in your area. While you can’t just toss it in the trash, most regions have facilities to handle hazardous wastes like gasoline. Here are the best options for finding authorized disposal sites:

• Look up “[your area] waste management” to get agency contact info.
• Call and explain you have old gasoline to dispose of – ask where you can take it.
• Staff should know potential locations like transfer stations, landfills, and collection events.
• Get details on quantity limits, approved containers, and any fees charged for gas disposal.
• Ask if you need an appointment or can do drive-up drop-off at facilities.
• Some agencies may even offer hazardous waste pickup if you can’t transport it.

Tapping into local waste management resources takes the guesswork out of finding where to properly dispose of hazardous fuels in your region.

Local Fire Departments

Since gasoline is highly flammable and a potential fire risk, the fire department often has insight on disposal options:

• Find contact info for your nearest fire station online or in the phone book.
• Call the non-emergency line and explain you’re seeking gas disposal guidance.
• Firefighters deal with combustible materials and likely have relationships with disposal sites.
• They may advise on safe handling procedures and give locations that accept old gas.
• Some fire stations hold designated collection days a few times a year to gather hazardous waste from the community for proper disposal.

Checking with the local fire department leverages their hazardous materials expertise to locate accessible, approved disposal sites for old gas.

Auto Repair Shops

Since they work with gasoline and other automotive fluids regularly, repair shops are another option:

• Ask your usual mechanic if they can take your old gas for proper disposal.
• Many shops have waste disposal contracts with services that will handle old gasoline.
• However, some shops may not accept outside gas due to liability concerns. Don’t take it personally if declined.
• Be prepared that a small fee may be charged by the shop for handling old fuel disposal.
• Get any estimated charges in writing upfront before leaving gasoline with the shop.

While results will vary, friendly auto shops may be willing to take that old gas off your hands and deal with disposal for you.

With a bit of research and outreach, you should be able to find a facility, agency, or business able to safely receive and handle disposal of your old degraded gasoline. Never resort to questionable dumping – protect the environment and follow the law by using authorized waste sites only.

Now that you know where to take it, let’s go over key pointers for safely transporting gas cans to the disposal facility. It’s not every day you have to chauffeur volatile liquid in your vehicle, so follow these precautions.

Transporting Gasoline For Disposal

You’ve got your old gas drained from the mower and stored properly in approved containers. Now it’s time to safely transport those gas cans to the disposal site. Gasoline is volatile so take precautions while driving with it in your vehicle. Follow these tips for secure transportation to avoid spills, fires, and inhaling harmful fumes.

Use Proper Gas Containers

Only transport old gasoline in purpose-made, government-certified gas cans:

• Never use food, drink or household chemical containers – gasoline will melt through plastic not meant for fuel.
• Check that your gas can has sturdy construction, a tight sealing lid, flame arrestor, and other safety features covered earlier.
• Make sure the can is in good shape with no significant rust, cracks, or damage.
• Confirm the container is clearly labeled “GASOLINE” so contents are obvious.
• Double-check that all caps, vents, and spouts are tightly closed before moving the can.

Use gas cans designed and approved to hold gasoline – and make sure they’re sealed shut. Don’t take any chances transporting questionable containers.

Drive Carefully to Avoid Spills/Leaks

Gas cans can tip, shift, or bounce around while driving, so take precautions:

• Place smaller gas cans snugly inside spill-proof tubs or bins to contain leaks.
• For larger containers, secure them upright on a flatbed trailer or in the bed of a pickup truck.
• Drive smoothly without quick acceleration or hard braking that could cause splashing.
• Take corners gently and watch speed bumps to avoid forces that could topple cans.
• Never leave filled gas cans loose in a trunk – vapors could enter car interior.

Careful driving maintains control over filled gas cans to prevent tip overs, spills, and leaks while en route to the disposal facility.

Do Not Smoke While Transporting Gasoline

This is absolutely crucial – do not smoke cigarettes or anything else while transporting gasoline!

• Gas fumes are extremely flammable and smoking could ignite an explosion.
• Pull over and get out of the car if you or a passenger feel an urgent need to smoke.
• Avoid sparks from cell phones, Bluetooth devices, chargers, or loose battery terminals.
• Turn your radio completely off so it won’t transmit signals that could ignite fumes.
• Pay attention for any smell of gasoline in the car so you can pull over promptly.

No smoking whatsoever, no exceptions – that’s the cardinal rule when handling gasoline to prevent potential disaster.

Additional Precautions:

• Keep windows open while driving to prevent buildup of gas vapors inside.
• Go directly to the disposal site. Don’t leave filled containers in a hot vehicle.
• Have a fire extinguisher and first aid kit in your car in case of emergency.
• Wear gloves when handling cans to avoid exposure. Wash skin and change clothes after transporting gasoline.

Take your job as a gasoline chauffeur seriously. Use common sense and follow basic safety protocols. Get that old lawn mower fuel disposed of properly without turning your weekly drive to grandma’s into a Mad Max movie stunt ride.

Thanks for sticking with this step-by-step guide! Now let’s get into cleaning up minor spills that may happen despite your safe handling efforts. It’s good to be prepared just in case.

Cleaning Up Gasoline Spills Safely

You’ve been super careful draining, storing, and transporting gasoline from your lawn mower. But fumes are strong, spills happen, and gas can splash out unexpectedly. Here’s how to safely clean up minor gasoline spills so they don’t create health hazards or fire risks.

Soaking Up Spills With Absorbents

For liquid gas that has spilled out:

• Immediately spread absorbent materials on the spill such as kitty litter, sand, vermiculite, or commercial absorbent pads.
• Allow sufficient time for the absorbent to soak up the spilled fuel – at least 15 minutes for thorough absorption.
• Use a stiff bristle broom to work the absorbent material around to soak up all liquid.
• Sweep up the soaked absorbent and dispose of properly in a sealed container.
• Repeat applications if the spill area still smells strongly of gasoline.
• Provide ventilation indoors during cleanup to avoid breathing vapors. absorbing materials contain spills by soaking up liquid gas so it can be removed safely.

Eliminating Stains/Odors From Surfaces

For spills on driveways, garage floors, patios, etc:

• Drench the stained surface with dish detergent and scrub thoroughly after absorbent removal.
• Rinse thoroughly – detergent helps break down gas residue.
• Follow with baking soda scrubbed into the area to deodorize and neutralize odors.
• Rinse again and allow to fully dry in fresh air. Repeat if any gasoline smell lingers.
• A bleach or degreaser cleaner can also help lift stubborn stains and smells.
• Avoid hot water, open flames, or sparks near spill areas until surfaces are clean and completely dried.

Thorough cleaning removes both stain and odor from gasoline contact areas. Just don’t mix cleaners containing bleach or ammonia – toxic fumes result.

Laundering Gas-Exposed Clothes

For spills on clothing:

• Take off any clothes exposed to gasoline fumes or liquid right away.
• For small stains, blot excess gasoline gently with rags – avoid spreading the stain.
• For serious saturation or skin exposure, rinse the area thoroughly with cool water.
• Pre-treat stains with dish detergent. Let sit 5 minutes before washing.
• Machine wash in HOT water with extra soap and stain remover added.
• Line dry outdoors – do NOT put gas-smelling clothes in an electric clothes dryer!
• Repeat laundering as needed until no smell remains before returning clothes to service. Discard if stains remain and smell persists after multiple washings.

Harsh chemical detergents help eliminate both the odor and fire hazard from spilled gasoline in laundry. Take care to fully remove gasoline before drying.

Tip: If you spilled a large amount of gasoline on your clothes, consider contacting hazardous materials cleanup services for assistance and proper disposal. Don’t take chances with excess gasoline exposure.

Stay safe if handling spills, but also rest assured that recent minor stains and smells can be remedied through prompt cleaning actions. Don’t let Settling for clothes and surfaces reeking of gasoline!

Now let’s move on to discussing some alternative methods for using up gasoline that has started to go bad but is still salvageable. Welcome to Plan B for your old gas!

Alternative Ways To Use Up Old Gasoline

What if your lawn mower gas isn’t totally shot, but just old enough that you don’t want to dump it directly into the tank? Here are some alternative methods to use up questionable fuel instead of disposing of it entirely.

Diluting With Fresh Gas In Equipment

Adding a small amount of old but still usable gas to a larger amount of fresh fuel can dilute it enough for engines to tolerate:

• Only use old gas that is discolored or smells stale – not contaminated liquids with debris/water.
• Estimate tank size in your mower, car, generator etc. and fill to around 75% with fresh gas.
• In a 10 gallon tank, add no more than 1/2 gallon old gas. For a 15 gallon tank, use 3/4 gallons old gas.
• The 25% old to 75% new ratio provides enough dilution for proper combustion.
• Run the engine moderately to burn through diluted fuel within a few days.

With larger amounts of new fuel, small portions of old gas can be effectively diluted so equipment keeps running.

Adding Fuel Stabilizers

Chemical additives help old gasoline maintain volatility and combustibility.

• Read labels to pick a stabilizer compatible with your equipment fuel type.
• Add stabilizer to old gas container according to instructions.
• Agitate or stir to fully mix stabilizer with the old fuel.
• Let stand for the recommended time to allow additive to rejuvenate the gasoline.
• Use reconditioned old gas within a few weeks before degradation resumes.

Fuel stabilizers are an option for extending the usability of old gas for a short while. But they can’t remedy severely degraded or contaminated fuel.

Letting Gasoline Evaporate

Don’t try this indoors! But in certain cases, you can let old gas evaporate:

• Only allow evaporation outdoors in a very well ventilated area away from ignition sources.
• Place container of old gas on an impermeable surface where spills will be contained.
• Leave container lid open so vapors dissipate into the air naturally over 1-2 weeks.
• Position the container out of reach and sight of children and pets. Mark it clearly.
• Have a fire extinguisher on hand in case vapors ignite unexpectedly.

Letting gas evaporate into the atmosphere isn’t ideal, but can be done safely with strict precautions against fire and other hazards.

Alternative tip: Use bad gas in a gasoline-powered weed trimmer outdoors instead of evaporating. The engine and exhaust system provide a controlled burn. Just avoid plants you want to keep!

With creativity and care, you may be able to use up old gas instead of disposing of it. But exercise extreme caution – don’t cut corners or do anything unsafe when handling, storing and using degraded fuel.

Now let’s discuss how to get lawn equipment running again after sitting with bad gas, in case some made it into the tank.

Starting Lawn Mower After Old Gas Exposure

Uh oh, you tried starting your lawn mower after winter storage and it won’t turn over or run rough. Chances are some old gasoline made it into the fuel system. Here’s how to get the engine going again after exposure to bad gas:

Draining Old Gas Completely

Start by thoroughly draining the old gas from the mower’s tank and components:

• Use a siphon hose or disconnect the fuel line to empty the tank as covered earlier. Get every last drop.
• Remove the carburetor bowl and drain any fuel from there. Dismantle carefully to avoid damage.
• With residuals emptied, reassemble the carburetor and reconnect the fuel line.
• Tip the mower back and forth to allow any remaining drips of old gas to flow into the tank where they can be siphoned out.

Completely removing all traces of old gasoline lets you start fresh with clean fuel system components.

Cleaning Carburetor Thoroughly

The carburetor jets, valves, and passages are vulnerable to gunking from degraded gasoline:

• With the carburetor bowl off, spray aerosol carb cleaner into jets, ports, and the float bowl cavity. Avoid plastic/rubber parts.
• Use compressed air to blow out passages in hard-to-reach spots.
• For stubborn buildup, run a narrow wire through jets and ports gently. Don’t enlarge openings.
• Rinse components with clean gasoline after cleaning to remove residue. Inspect closely for remaining debris.
• Replace any badly varnished or damaged parts like gaskets, valves, filter screen.

Thorough cleaning ensures the carburetor won’t restrict fuel flow or choke the engine when fresh gasoline is added.

Adding Fresh Gas/Stabilizers

With the system drained and cleaned, add new gasoline:

• Use a fresh gas can – don’t mix old questionable fuel in yet.
• Add fuel stabilizer to the new gasoline according to instructions.
• Slowly pour a little stabilized fuel into the tank and replace the fuel line to fill carburetor.
• Avoid flooding the engine – start with less than a full tank.

The fresh treated gasoline will dissolve residues remaining from bad gas in the fuel system.

Trying Again If Issues Persist

If the mower still won’t start or runs rough with fresh stabilized fuel added:

• Drain the new gas and repeat steps above until you’re certain all old gas residues are removed.
• Try adding a teaspoon of rubbing alcohol to the fresh fuel. This extra step may free stuck float valves and dissolve other deposits.
• Check for spark, compression issues if starting problems persist after double checking the fuel system cleaning.

With persistence, you can overhaul an engine fouled by old gas. Just methodically eliminate the old fuel then give new gas a clean path.

Tip: Always run gasoline-powered equipment dry before winter storage to avoid this issue next spring. Use fuel stabilizer and consider draining the carburetor bowl.

Now that you’re a pro at wrangling old gas in mowers, let’s move on to discussing key safety measures when handling gasoline, because this flammable liquid is no joke.

Safety Tips For Handling Old Gasoline

Gasoline vapors are toxic and the liquid itself highly flammable. Use extreme care when draining, storing, transporting and disposing of gasoline from your lawn mower or any source. Follow these safety precautions closely to avoid health hazards and potential disasters:

Work Outdoors Only

Gasoline fumes can quickly overwhelm the air in enclosed spaces:

• Only drain and transfer gasoline outside. Siphoning, pumping, pouring – do it all outdoors.
• If you must store containers in a shed or garage temporarily, ventilate the space extremely well.
• NEVER drain or transfer gasoline indoors under any circumstances. Fumes disperse too slowly indoors.

Outdoor airflow prevents dangerous buildup of toxic and flammable gasoline vapors. Work inside only in a dire emergency with massive ventilation.

Avoid Inhaling Fumes

Your nose detects gas fumes well before they reach hazardous levels, so heed that warning:

• If you smell gasoline, position yourself upwind of the container to limit vapors entering your breathing zone.
• If headache, nausea, or burning eyes occur, get to fresh air right away. Seek medical help if symptoms persist.
• Wear an organic vapor respirator when exposure is likely – draining tanks, cleaning spills, etc.

Gasoline fumes cause chemical pneumonia if inhaled deeply, so avoid breathing them at all costs.

Wash Skin or Eyes Exposed Immediately

Gasoline can irritate skin and damage eyes:

• If gasoline gets on your skin, wash hands and arms thoroughly with cool water and soap.
• If it splashes into your eyes, flush with water for at least 15 minutes then seek medical attention – don’t just rinse and resume work.
• Change clothes if soaked in fuel – launder twice to eliminate vapors before wearing again.
• Apply an antibiotic cream to reddened skin after washing off gasoline.

Prompt cleansing minimizes damage if you come into direct contact with liquid gasoline. Don’t brush it off.

Call Poison Control if Ingested

Swallowing gasoline can be lethal:

• Call 911 or the National Poison Control hotline at 800-222-1222 if gasoline gets in your mouth.
• Do NOT induce vomiting unless instructed by Poison Control. There is risk of chemical pneumonia if vomited material is inhaled.
• Drink milk or water to dilute the swallowed gasoline, unless advised otherwise by medical professionals..
• Follow all directions from Poison Control or emergency medical personnel exactly for proper life-saving treatment.

Unintentional ingestion requires immediate medical intervention. So keep gas well away from children and labeled clearly.

Additional Precautions:

• Keep a fire extinguisher on hand anytime you handle gasoline, just in case.
• Allow spilled gas to fully evaporate before using any ignition sources nearby.
• Place containers on impervious surfaces to contain leaks – not dirt or grass.
• Limit gasoline handling to adults only. Keep kids and pets away from the area.

Gasoline demands extreme care. Follow all instructions precisely each time, without exceptions or shortcuts. Your health and safety depend on it!

Let’s shift gears and talk about how following proper disposal procedures protects the wider community and environment too. It’s not just about you – gasoline has many risks if mishandled.

Following Proper Disposal Guidelines

Dumping gasoline improperly can negatively impact community health and environmental quality. Follow these tips for legal, considerate disposal that protects the public:

Review Local Hazardous Waste Regulations

Familiarize yourself with laws in your municipality, county, and state:

• Government websites will outline proper handling and disposal methods for hazardous household chemicals like gasoline.
• Most areas prohibit putting gasoline into the regular trash or dumping it outside.
• There are often limits on storage quantities. Gas cans over 5 gallons may require special permits.
• Burning gasoline off in the open is usually banned within city limits due to air pollution.
• Review the major requirements so you can follow them, avoiding fines or legal issues.

Knowing the hazardous waste rules for gasoline puts you on the right side of the law.

Never Dump Gas Down Drains or On The Ground

Pouring gasoline down storm drains or onto soil is very risky:

• Gasoline will flow directly into lakes, rivers, and groundwater if washed into storm drains, spreading pollution widely.
• Just a small amount of gas can render large quantities of groundwater unusable as drinking source.
• The toxic chemicals in gasoline kill microbes in soil that support plant life and agriculture.

Keep every drop out of waterways and soil by using authorized collection points. Don’t take chances dumping it.

Take Gasoline Only To Approved Disposal Sites

Facilities certified to handle hazardous wastes have controls in place:

• Special handling procedures prevent pollution from spilled gasoline at disposal sites.
• Hazardous waste professionals have training to process chemicals like gasoline safely.
• Licensed disposal sites are designed to legally incinerate, recycle, or otherwise neutralize hazardous fuels.

Following the proper disposal path keeps toxic gasoline out of the wider environment.

Ask Waste Management For Help If Needed

Don’t be afraid to consult the experts about disposing of old gasoline:

• Local waste authorities can guide you on legal transport and disposal methods.
• Explain your situation – they may provide pickup service if you’re unable to deliver gasoline to a collection point.
• Staff can advise you if any waste events or facilities are upcoming for convenient, supervised disposal.

With support from waste management authorities, you can remove old lawn mower gas from your property confidently.

When discarding hazardous substances, what you do affects more than just yourself. Handling gasoline carefully and legally prevents damage to community health and the environment we all share.

Now let’s wrap up with tips to avoid the gas disposal issue altogether by keeping fuel fresh and equipment emptied before storage. Prevention is the best approach!

Storing Gasoline Properly To Avoid Buildup

The best way to avoid the headache of disposing old gasoline is to not have much leftover in the first place. Use these tips to keep your gas fresh and equipment empty, preventing waste buildup:

Buy Only What You Need

Don’t overbuy fuel that may go stale before you use it:

• At the gas station, only fill the portable cans that you plan to immediately take to equipment needing fuel.
• Fill mower and equipment tanks directly with only enough gas to finish the task at hand.
• Calculate your usage and buy accordingly. You don’t have to top everything off to the brim.
• Return any unused gas to approved storage cans after finishing yardwork, to avoid leaving gas sitting in equipment over weeks/months.

Buying excessive quantities leads to old, degraded gasoline accumulating over time.

Use Gas Within 6 Months

Try to cycle through gasoline supplies well within the typical 6 month shelf life:

• Monitor your storage container fuel levels and filling dates using a marker.
• When topping off equipment, choose cans with oldest fill dates first.
• Funnel any leftovers from partly filled equipment tanks back into storage cans promptly after finishing mowing or other yardwork tasks.
• Buy only enough gas for imminent needs so you cycle through it faster.

Turning over gas cans regularly prevents aging beyond the stable storage period.

Use Fuel Stabilizers

Additives extend the usability window of stored gasoline:

• Add fuel stabilizer to storage cans when first filling them up according to label directions.
• Also add stabilizer to equipment fuel tanks at fill-up for longer-term storage between uses.
• Remember to prep winterized outdoor power equipment with stabilizers if storing more than 2 months.
• Use older gas first after treating with stabilizers and before the additive fully wears off.

Stabilized gasoline resists degradation from oxidation and evaporation better over time.

Run Equipment Dry Before Storing

Don’t let gas sit unused in tanks between uses:

• At end of mowing season, keep mower running until it shuts off from lack of fuel.
• Start other mid-season equipment periodically to burn off stale fuel, then refuel.
• Drain excess gas from partly filled tanks into approved storage cans for quicker cycling.

Emptying equipment minimizes stale gasoline accumulation. Less old gas to deal with makes life easier!

Avoiding buildup of old gasoline just takes some forethought and discipline not to overbuy fuel. Follow our tips to keep your gas fresh, rotate supplies efficiently, and empty equipment before long-term storage. Implementing good fuel storage practices makes proper disposal less frequently needed. Stay ahead of the curve with your gas!

Key Takeaways on Disposing of Old Gasoline from Lawn Mowers

Dealing with stale, degraded gasoline can be a nuisance and safety risk if you don’t handle it properly. Here are the key tips to remember:

• Work outdoors only when draining and transferring old gas. Avoid breathing fumes.
• Store and transport gas in approved containers labeled clearly to indicate contents.
• Find authorized hazardous waste facilities in your area to dispose of bad gasoline legally.
• Add only small amounts of old gas to fresh fuel for dilution. Stabilizers can also extend shelf life.
• Clean up spills promptly with absorbers. Use detergent and ventilation to remove residue.
• Thoroughly drain stale gas and clean components before adding fresh fuel and restarting equipment.
• Follow all local regulations and guidelines when handling, storing and disposing of gasoline.
• Prevent buildup of old gas by buying only needed amounts, turning over supplies within 6 months, and emptying equipment tanks prior to storage.

Properly disposing of lawn mower gasoline keeps your equipment running optimally, while also protecting your family’s health and the environment. Implement these gas safety best practices for smooth mowing this season.

Frequently Asked Questions

Q: How do I know if the gasoline in my mower is bad?

A: Signs of bad gas include darkening color, sour smell, separation, debris/particles, and thickened consistency. The best test is to drain some into a clear jar and compare appearance and odor against fresh gas.

Q: Can I just pour old gasoline down the storm drain to get rid of it?

A: Absolutely not! Dumping gas into storm drains or onto the ground is illegal and environmentally damaging. Take old fuel only to approved hazardous waste disposal sites.

Q: My mower won’t start after sitting with old gas – what should I do?

A: Drain the old gas completely, then clean the fuel system thoroughly by removing and flushing the carburetor. Add fresh treated fuel and make sure spark plug and compression are good. The engine should turn over after clearing out stale gasoline residues.

Q: How can I prevent gasoline from going bad when storing equipment?

A: Use fuel stabilizer additives when filling gas cans and equipment tanks. Run outdoor power equipment dry before winterizing. Store gasoline tightly sealed and out of direct sunlight/heat to maximize shelf life.

Q: Is it safe to transport and dispose of gasoline myself?

A: You can transport small amounts safely in approved gas cans secured upright in a spill tub or tray. Follow safety precautions and always take old gasoline to a hazardous waste facility – never dump it illegally. Ask waste management officials for help disposing if needed.

Q: How much does it cost to dispose of old gasoline?

A: Most municipal household hazardous waste facilities accept limited quantities of old gasoline at no charge. For larger amounts, there may be small disposal fees. Auto repair shops may also charge modest fees to handle old gas disposal for you.
