Aerosols that contain non-hazardous materials: If you can’t find someone to donate your extra material to, the non-hazardous contents can be emptied by spraying them into a garbage can. Then place the empty can in your blue bin. Most aerosol cans are steel containers pressurized with propellants, (e.g. butane).
Should aerosol cans be punctured empty?
Please do not do that! Using a screwdriver as an aerosol can puncturing device is dangerous, for several reasons. Most aerosol cans made of steel or aluminum can be recycled – but only if empty. Otherwise, the EPA may classify it as hazardous waste depending on the original contents.
How do you depressurize an aerosol can?

Aerosol cans containing paint, pesticides, and cleaning products are several examples of materials that may be hazardous when discarded.
What happens if you pierce an aerosol?
Do not pierce aerosols, even when they are empty, because there is always some pressure, and possibly some of the product left. It may be flammable or cause injury if you pierce the can. The pressure inside the can increases greatly in the heat and may cause it to burst.
Can you throw aerosol cans away?
Spray Can Disposal – The Risk of Flammables Unless aerosol cans are completely emptied in a safe manner, they pose a risk for recycling or landfill workers. In fact, you should never dispose of aerosol cans in the trash for this very reason.
Why is it important not to puncture an aerosol can?
Why is it important to not puncture an aerosol can? The pressure of the gas inside of the can is greater than the pressure of the outside so it would have to equalize which means that the can will explode.
Why has my aerosol stopped working?
A Cleaning, Clearing Trick Instead of fiddling with a needle or pin to clear a clogged nozzle, use a water-displacing lubricant spray to clear it. Remove the clogged nozzle from the spray can, then remove the nozzle device from the top of the water-displacing lubricant.
Can I put full aerosols in the bin?
Here are a few tips for disposing of aerosols safely: 1. If it is completely empty, your aerosol can may go into the normal recycling for cans/tins.

How do you dispose of wd40?
Leaking cans should be placed in plastic bag or open pail until pressure has dissipated. Empty aerosol cans should not be punctured or incinerated; bury in land fill. Liquid should be incinerated or buried in land fill. Dispose of in accordance with local, state and federal regulations.
What states have adopted aerosol cans as universal waste?
Alaska, Arizona, Kentucky, Illinois, Indiana, Iowa, Michigan, North Carolina, and Pennsylvania have adopted the EPA Final Rule. California, Colorado, Minnesota, New Mexico, Ohio, and Utah had aerosol cans listed as Universal Waste prior to the Federal Final Rule.
What gas law is aerosol can?
The Gay-Lussac’s law states, ‘At constant volume, pressure of a gas is directly proportional to its absolute temperature in kelvin’. All aerosol cans come with a warning label that reads ‘Protect from sunlight and do not expose to temperatures exceeding 50°c’.
Are punctured aerosol cans universal waste?
EPA is allowing leaking or damaged aerosol cans to be managed as universal waste. Such cans must be packaged in a separate closed container, overpacked with absorbents, or immediately punctured and drained. Handlers must develop and follow a written procedure detailing how to safely puncture and drain aerosol cans.
At what temperature will an aerosol can explode?
Make-up and Hairspray Hairspray, or any aerosol can, should not be exposed to temperatures greater than 120 degrees because the pressurized container can quickly explode.
Do aerosol cans explode if punctured?
Hazards to workers But any number of problems, such as a puncture, a faulty valve, excessive temperatures, or corrosion can result in unintended depressurization. In the most severe cases, aerosol cans may explode, burning nearby workers and showering them with steel shrapnel.
How does an aerosol can explode?
You should never throw an aerosol can onto a fire or leave it in direct sunlight – even if it is empty. This is because the pressure will build so up so much that the can will burst (and explode if there is a naked flame nearby). the gas pressure increases. more of the liquefied propellant turns into a gas.
Can aerosol cans be checked in luggage?
TSA has determined that liquids, aerosols and gels, in limited quantities, are safe to bring aboard aircraft. If you want to travel with your full-size aerosol containers of antiperspirant, hairspray, suntan lotion, shaving cream, and hair mousse, you can do so by packing them in your checked baggage.
Why are aerosols flammable?
Most aerosol cans use a hydrocarbon propellant. While hydrocarbons are less harmful to stratospheric ozone than CFCs or HCFCs, they are very flammable. An aerosol product containing a hydrocarbon propellant can become a fire hazard if sprayed near fire.
