Proper Battery Disposal

Batteries contain heavy metals such as mercury, lead, cadmium and nickel, which can contaminate the environment when batteries are improperly disposed.

To prevent short circuit and battery leaching into the ecosystem, batteries should be disposed as outlined below:

      • Use clear tape or clear bags to separate batteries terminals from contacting other terminals or metal objects.
      • Use only clear bags so batteries can be easily identified and sorted for recycling.
      • Store batteries in leak proof container and contact Aramark facilities for used batteries pick up.
      • Do not throw batteries into regular trash.

    Aerosol Cans

    What are Aerosol Cans?
    Aerosol cans are self-contained dispensing systems where a substance is stored inside a small metal canister and pushed out as a fine mist, spray or foam. These cans are dangerous because of the unusual mix of substances stored under pressure inside the canister. The biggest problem with aerosol cans is their potential to ignite and explode.

    Handling Aerosol Cans
    Aerosol cans may present a hazard due to the active ingredients they contain and the accidents they can cause when overheated, ruptured, or dropped. However, aerosol cans may be handled as solid (non hazardous) waste if they meet the following criteria:

        • The aerosol products have been used for their intended purposes so that when holding the can upright and pressing down on their nozzle, not enough product comes out of the can.
        • No more than 3% of the original net content weight remains in the cans.
        • No more than one inch of liquid remains in the bottom of the cans.
        • The cans did not hold chemicals formulations with sole active ingredients in the F 027 (used and unused formulations for wood preserving) or P listing hazardous waste.

        Please note that aerosol cans that are not empty or may be hazardous should be managed and stored safely. Safe work practices for aerosol cans include:

        1. Store the cans in dry areas.
        2. Separate the cans from flammable liquids.
        3. Store the cans at least 3 meters from heat and sources of ignition.
        4. Protect the cans from direct sunlight and excessive temperatures.
        5. Place the cans in stable surfaces to avoid dropping and carefully arrange cartons containing cans to prevent collapse.
