Pennsylvania’s medical waste disposal regulations are managed by the Pennsylvania Department of Environmental Protection. The complete detailed disposal requirements are outlined in CHAPTER 284. INFECTIOUS AND CHEMOTHERAPEUTIC WASTE .
In addition to the state medical waste environmental regulations there are some Occupational Safety and Health Administration rules that apply to medical/infectious waste. Pennsylvania is one of 26 states covered entirely by the federal OSHA program. OSHA rules (Occupational Exposure to Bloodborne Pathogens Standards) impact various aspects of medical/infectious waste, including management of sharps, requirements for containers that hold or store medical/infectious waste, labeling of medical/infectious waste bags/containers, and employee training.
