Environmental Safety and Waste Management Flashcards

Under EPA regulations, a healthcare facility that generates between 100 kg and 1,000 kg of hazardous waste per calendar month is classified as a:

Answer: Small Quantity Generator (SQG)

EPA's generator classification thresholds under RCRA are: VSQG ≤100 kg/month, SQG 100–1,000 kg/month, and LQG >1,000 kg/month. Generator status determines storage time limits, emergency planning requirements, and manifest obligations. CESQG is the old term replaced by VSQG under the 2018 Generator Improvements Rule.

Regulated Medical Waste (RMW) in a hospital must be tracked using a manifest system in most states primarily because:

Answer: State environmental agencies require documentation of RMW from point of generation to final disposal

Regulated Medical Waste tracking (manifests/tracking forms) is required by state environmental agencies — not OSHA, CDC, or TJC — to ensure a documented chain of custody from generator to licensed treatment and disposal facility. While OSHA regulates occupational exposure to bloodborne pathogens, it does not mandate RMW manifests.

A hospital pharmacy is disposing of unused chemotherapy drugs. These pharmaceutical wastes are BEST classified and managed as:

Answer: RCRA P- or U-listed hazardous pharmaceutical waste requiring proper manifesting and licensed disposal

Most antineoplastic (chemotherapy) drugs are listed RCRA hazardous wastes (P- or U-listed) and must be managed under full RCRA hazardous waste regulations, including manifesting and disposal at a licensed facility. They cannot go in red bags (RMW pathway), regular trash, or universal waste streams. EPA's 2019 Pharmaceutical Hazardous Waste Rule formalized this pathway.

Which regulatory framework primarily governs the use, storage, and disposal of radioactive materials used in nuclear medicine departments?

Answer: Nuclear Regulatory Commission (NRC) 10 CFR Parts 19, 20, and 35

The NRC (or Agreement State equivalent) regulates radioactive materials in healthcare under 10 CFR Part 35 (Medical Use of Byproduct Material), Part 20 (Standards for Protection Against Radiation), and Part 19 (Notices, Instructions, and Reports to Workers). OSHA, EPA RCRA, and DOT play secondary roles in occupational protection and transport, but the NRC is the primary regulator for use and disposal.

During an environmental rounds inspection, a healthcare safety professional notices sharps containers that are three-quarters full but have not been picked up for exchange. The MOST immediate concern is:

Answer: Increased risk of needlestick injury to staff forced to compress or overfill containers

Overfilled sharps containers are a direct, immediate occupational safety hazard — needlestick injuries significantly increase when containers are compressed or overfilled. OSHA's Bloodborne Pathogen Standard (29 CFR 1910.1030) requires containers to be replaced before they reach the fill line. Regulatory non-compliance is also a concern, but the immediate patient/worker safety risk from needlestick exposure ranks highest.

A healthcare facility's spill of a mercury-containing sphygmomanometer in a patient room requires response under which primary framework?

Answer: EPA mercury reduction guidelines and state environmental notification requirements if the spill exceeds threshold quantities

Mercury is a toxic heavy metal regulated by EPA under RCRA and by many states as a reportable hazardous substance. Even small mercury spills require proper cleanup with specialized equipment (mercury vacuum, not a regular vacuum) and may require state environmental notification if they exceed reportable quantities. It is not a bloodborne pathogen, not flammable, and updating an SDS is not the primary response action.
