Hazardous waste can never be poured down the drain or placed in regular trash, unless specified by your supervisor or the safety officer. And remember that "the solution to pollution is NOT dilution". If you are not sure of how to dispose of a chemical, ask your supervisor.

These are areas where hazardous wastes that are generated as part of the laboratory activity are collected and properly stored until they are transferred to the main accumulation area.

Each faculty member assigned a laboratory is responsible for the management of the designated Satellite Accumulation Areas for the collection of hazardous wastes generated in his/her laboratory. The following requirements apply to the operation and management of a Satellite Accumulation Area:

• Signage - each area must have a sign designating it as the Satellite Accumulation Area.

• Weekly Inspection - each area must be inspected weekly, the items to be inspected are listed on the inspection sheet. The Principle Investigator in charge of the laboratory is responsible for ensuring this inspection is done weekly.

• Segregation and Containment - the wastes must be separated by chemical compatibility groups, each group of containers must be provided with appropriate secondary containment. Containment trays and tubs are available from OEH&S. Additional information on compatibility is provided below.

• Storage - only one container per waste stream (type of waste) is allowed for each Satellite Accumulation Area, i.e.: one container for halogenated solvents, one container for non-halogenated solvents.

• Labeling - all waste containers must be labeled with the words "Hazardous Waste" the chemical constituents and the hazard classification (Ignitable, Corrosive, Reactive or Toxic). Containers in Satellite Accumulation Areas shall not be dated until they are full. Waste containers may be kept in a Satellite Accumulation Area until they are full. When full the container must have that date indicated on the label and be removed from the Satellite Accumulation Area within three days.

• Closure - all containers must be closed at all times except when actually adding waste. A funnel sitting in the mouth of the bottle is not the same as "closed container"

Each container must be labeled with the words "Hazardous Waste"

Use the EH&S label pictured to the left on every bottle designated for hazardous waste storage.

Paste the bottem part of the label onto the bottle as it is being filled. Once full, paste the rest of the label on the bottle.

Containers in Satellite Accumulation Areas shall not be dated until they are full.
