San Joaquin County Household Hazardous Waste Program Aerosols Sorting & Packing Policy Aerosol products are packaged in closed steel cans that come in a variety of sizes. Products including deodorants, hair sprays, automotive cleaners, household cleaners, paints, and pesticides are packaged in aerosol form. Each aerosol can also contains a propellant in the form a compressed, liquefied gas such as butane or propane. The compressed gas is responsible for creating the pressure which propels the product out of the can when the valve is pushed open. The propellant is also responsible, in part, for the aerosol can management method. Since most of the propellant gases are flammable, they are categorized and shipped under the flammable gas (Division 2.1) hazard class. Re -use is the preferred materials management method because it conserves energy and resources and saves disposal costs. Aerosol paints (spray paint) and other consumer products in reusable condition are reserved for beneficial reuse. Customers must be 18 or older, or accompanied by an adult, and must sign the Reuse Liability Waiver Form, as described in the County Reuse Policy, before taking any aerosol products from the HHW Facility Reuse Room. To be considered for reuse, products must meet the following Quality Assurance criteria: the product is in the original container and appears to be uncontaminated the container is at least half full • the label is intact and readable • the container is not compromised and is relatively clean ■ the product has not expired and is currently available over-the-counter ■ the product is not on the banned or restricted pesticide list, and is not a pesticide recommended for use on food crops Recycling or Incineration: Aerosol products that are not in reusable condition shall be sorted and packaged appropriately and sent for recycling or incineration.* Aerosol products are managed in a safe manner to protect against accidental discharge, in accordance with the specific conditions outlined in 49 CFR § 173.306 (formerly US DOT -SP 12842): ■ Aerosol products are first screened to verify the contents are contained in strong outer packaging (the can is not leaking or cracked). Empty, partially used, and full household aerosol products in strong outer packaging shall be protected against accidental discharge by employing the following controls: Each aerosol container must be fitted with a protective cap to protect the valve stem, or if no protective cap is available, the valve stem must be removed from the can. Aerosol products in compromised packaging (can is leaking, cracked, or the product is otherwise not contained in strong outer packaging) shall be segregated and packaged appropriately. *§ 173.306(k), authorizes the highway transport of aerosol containers conforming to 49 CFR § 173.306 not to exceed 500 kg (1,100 pounds) when transported for the purpose of recycling or disposal.
