Accumulation Container – A container used to collect waste in a satellite accumulation area.
Biohazard – Biological material that contains, or may contain pathogens that can cause disease in humans or animals, or that poses any other risk requiring inactivation or disinfection before final disposal.
Controlled Substance –A drug or chemical whose manufacture, possession or use is regulated by the United States Drug Enforcement Agency (DEA).
Consolidate/Consolidation – Mixing similar wastes together, generally from smaller containers into larger accumulation containers.

Satellite Accumulation Area (SAA) – Any area where hazardous waste is generated and stored until containers are full, up to 55 gallons total for all waste (See Regulatory Overview). SAAs must be at or near the point of waste generation, within the same room.
Universal Waste – Classification of hazardous waste managed under a special exemption to encourage recycling of certain materials. These wastes are still subject to certain regulatory requirements. Materials that can be managed as Universal Waste are:
- Batteries
- Fluorescent light bulbs/lamps
- Mercury containing devices
- Pesticides
Unknowns – Unidentified chemical waste resulting from lack of proper identification or labeling.
Waste Chemical – Any expired, spent or unwanted chemical or chemical mixture, or chemical product, including hazardous and non-hazardous wastes.
