Buddy System: A system for organizing employees into work groups in such a manner that each

member of the work group is designated to be observed by at least one other member of the

group at all times. The purpose of the buddy system is to provide rapid assistance to employees

in the event of an emergency.

Chemical Hazard: The exposure of employees to any regulated or non-regulated hazardous

materials (solids, liquids, and gases; natural and man-made), with the potential for causing harm to

people, the environment, or property when released.

Confined Space: An enclosed area that has one or more of the following characteristics:

It is not intended for continuous occupancy,

It has restricted entry and exit, and

It may contain potential or known hazards.

Contamination Reduction Corridor: The area that controls access into and out of the

Exclusion Zone/Radiological Area and where personnel decontamination activities take place.

Contamination Reduction Zone: The transition area between the Exclusion Zone and Support

Zone. The area where decontamination procedures take place.

Controls: Changes in the work processes and/or working environment with the objective of

controlling the hazards either by eliminating the responsible agents, or reducing them to levels

believed not to be harmful to health, as well as by preventing exposure to workers.

Critical Operations: Those emergency operations necessary for the safe emergency shutdown of

an operation, site, task, or piece of machinery.

Critical Operations Personnel: Those personnel identified in writing and trained to accomplish

emergency shutdown operations. These personnel may be required to delay their own evacuation

of the site during an emergency.

Emergency (Confined Space): Any occurrence (including any failure of hazard control or

monitoring equipment) or event internal or external to the confined space that could endanger

entrants.

Emergency (Site): A sudden and unexpected event, taking place on the site, and requiring

urgent action for control or remediation in order to minimize the danger to workers, the public,
