The toxicological/radiological properties of the substance,

The physical state of the substance,

The quantity and rate of release,

The method of release,

The atmospheric conditions, and

Local topography.

Onsite refuges should be identified and provided with proper equipment for localized

emergencies not requiring site evacuation. Examples of equipment a refuge might contain are:

Water for decontamination,

Communications network with site emergency operations center,

Emergency personal protection equipment,

First-aid supplies,

Required special monitoring devices, and

Fire extinguisher.

11.6. SITE SECURITY AND CONTROL

In an emergency, the Facility Emergency Coordinator should ascertain who is on site, and

control the entry of personnel into hazardous areas. In an emergency, as in daily work activities,

the site should be divided into three areas: Exclusion Zone, Contamination Reduction Zone, and

Support Zone. Only necessary rescue and response personnel should be allowed into the

Exclusion Zone. A personal locator system should be used to locate all personnel on site.

Checkpoints (or a series of checkpoints) should be established through which all personnel

entering or exiting the emergency site should pass. Checkpoint information should include:

Name (affiliation),

Time of entry/exit,

Zones or areas to be entered,

Tasks to be performed, and

Protective equipment worn and air time remaining.

11.7. EVACUATION ROUTES/PROCEDURES

Primary and alternate routes should be established for evacuating victims and endangered

personnel. Routes should be directed from the Exclusion Zone, through an upwind

Contamination Reduction Corridor to a Support Zone, then to an offsite location.

The following guidelines should be used to assist in establishing safe emergency evacuation

routes and developing procedures for their use:
