Managing Hazardous/Dangerous Waste: General Context �Container Management Requirements: labeling: hazardous/dangerous waste label risk label, if applicable accumulation start date, if applicable closed containers, unless in use containers in good condition and not leaking aisle space between containers, if applicable accumulation time limit: depends on generator status weekly inspections of hazardous waste accumulation area

High Level Disinfectants: Examples and Safety Concerns �Glutaraldehyde: Often used at 2 -4%; designates as dangerous waste at 1% Linked with a variety of health effects, ranging from mild to severe, including asthma, breathing difficulties, respiratory irritation, and skin rashes Best Practices for the Safe Use of Glutaraldehyde in Health Care: https: //www. osha. gov/Publications/glutaraldehyde. pdf �ortho-phthalaldehyde (OPA): o Often used at 0. 55%; designates as dangerous waste at 0. 01% o May cause eye, skin and respiratory irritation o May elicit an allergic reaction o May cause sensitization by repeated skin contact

High Level Disinfectants: Examples and Safety Concerns �Peracetic Acid Corrosive and oxidizer; designates as dangerous waste at 0. 1% Poison by ingestion Corrosive to skin and can cause serious eye damage Severely irritating to respiratory tract, potentially lethal �Ethylene Oxide (Et. O) Flammable and highly reactive Acute exposures to Et. O gas may result in respiratory irritation and lung injury, headache, nausea, vomiting, diarrhea, shortness of breath, and cyanosis Chronic exposure has been associated with the occurrence of cancer, reproductive effects, mutagenic changes, neurotoxicity, and sensitization OSHA Safety and Health Topics: https: //www. osha. gov/SLTC/ethyleneoxide
