P-Listed Chemicals & Hazardous Wastes The Environmental Protection Agency (EPA) has identified a number of chemicals on the “P-List” that present an especially acute hazard when disposed of as hazardous waste. Because they are extremely dangerous, there are more stringent requirements when disposing of P-Listed hazardous waste. ►►► When collecting P-Listed hazardous waste (listed below) in the lab, do not ever accumulate more than 1 quart (~1 L) at any given time. ►►► When you have empty containers that previously held a P-Listed chemical, these must also be disposed of as hazardous waste. Bring these empty containers to the Hazardous Waste Room. Do not wash or re-use these containers. [Review the UNO Regulated Waste Guidelines for information on proper hazardous waste disposal.] ►►► Disposable materials that become contaminated with p-listed chemicals (ex. Gloves, weighing boats, paper towels, etc.) must also be disposed of as hazardous waste. Non-disposable materials must be triple-rinsed to remove contamination. The rinsate must be collected as hazardous waste. Materials contaminated with P-Listed chemicals may not be washed or re-used until they have been triple-rinsed. [Review the UNO Regulated Waste Guidelines for information on proper hazardous waste disposal.] Most Common P-Listed Chemicals • Label the waste as hazardous waste in accordance Chemical Name CAS # with the UNO Regulated Waste Guidelines. Just like Acrolein 107-02-8 all other hazardous wastes, P-listed wastes must be Allyl Alcohol 107-18-6 labeled with the completed UNO Hazardous Waste Arsenic Compounds Varies Inorganic Cyanide Varies Label and the applicable GHS Pictograms. Salts Carbon Disulfide 75-15-0 • Use disposable materials whenever possible. Triple- Cyanogen & 460-19-5, 506-77-4 rinsing containers that held P-Listed chemicals creates Cyanogen Chloride 2,4-Dinitrophenol 51-28-5 a much larger volume of hazardous waste for Epinephrine 51-43-4 disposal, which creates a greater risk and is more Nitrous & Nitric 10102-44-0, 10102- expensive. Consider using disposable containers to Oxides 43-9 prevent generating excess waste.

Gloves, weigh boats, paper towels, and other materials that are contaminated with P-Listed chemicals must be collected in this container for disposal. Label this container as you would any other hazardous waste, according to the UNO Regulated Waste Guidelines.
