Definitions (Section 4)

Consolidated chemical contingency plan. Plan developed to integrate various regulatory requirements for hazardous material, including hazardous waste and emergency planning into a single functional document

Emergency responder. Person(s) with the training and medical surveillance required to respond to chemical releases which could expose them to health hazards, such that the releases are controlled and cleaned up in a safe and healthful manner so as not to endanger themselves or other employees

Facility emergency plan. Plan including information on spill response capability for each listed facility

Hazardous material. Any material that, because of its quantity, concentration, or physical or chemical characteristics, poses a significant present or threatened hazard to human health and safety or to the environment, if released into the workplace or the environment

Material safety data sheet. A document produced by chemical manufacturers and importers to relay chemical, physical, and hazard information about specific substances

Responder. Person(s) who discovers spill and takes appropriate actions to minimize impacts of spill

Secondary containment. A safeguarding method used to prevent unplanned releases of toxic or hazardous materials. Secondary containment is external to and separate from primary containment

Spill. A spill is the release of any material that results in an increased risk or potential risk to human health, the environment and/or property. Spills at SLAC are classified into one of three groups:

• Non-emergency. No potential exposure risk to human health, there is no uncontrollable imminent threat to the environment, and
• The spill consists of a material the nature and potential hazards of which are known
• The spill can be cleaned up with readily available spill response cleanup equipment and supplies

• Emergency. There is a potential exposure risk to human health or an uncontrollable imminent threat to the environment, and any of the following apply:
• The spill consists of material that has hazards unfamiliar to personnel.
• The spill is regarded by personnel as posing a potential exposure risk to human health.
• The spill contains a significant amount of hazardous material that cannot be prevented from migrating into a storm drain.
• The spill creates a gas plume with the potential to move off-site into the surrounding community.

• Radioactive. The spill involves any radioactive material.

Spill prevention, controls, and countermeasures plan. Plan developed to provide information to prevent, control, or mitigate the discharge of oil or oil products
