Development of the Site Map

DOE-EM-STD-5503-94

Reducing accidental spread of hazardous substances from equipment in the contaminated

area(s) by workers,

Confining work activities to the appropriate areas,

Facilitating the location and evacuation of personnel in case of an emergency,

Establishment of the "buddy system",

Establishment of appropriate communication systems,

Implementation of worker safety procedures, and

Identification of the nearest medical facilities.

9.2. DEVELOPMENT OF THE SITE MAP

The purpose of the site map is to assist site personnel in planning and organizing response

activities. Site maps should be updated during the course of site operations to reflect:

New information, such as information gained after initial site entry or from subsequent

sampling and analysis activities; and

Changes in site conditions, including changes resulting from accidents, ongoing site

operations, hazards not previously identified, new materials introduced on site,

unauthorized entry or vandalism, and weather conditions.

The site map should be developed prior to the initial site entry using information obtained during

the preliminary evaluation. The map should include:

Prevailing wind direction;

Site drainage points;

All natural and man-made topographic features including the location of buildings,

containers, impoundments, pits, ponds, and tanks;

Location of specific work zones including radiological and non-radiological postings;

Any other site features;

Locations of all potential hazards that were identified through the interview/records

research;

The perimeter reconnaissance;

The initial onsite survey should be plotted on the site map;

Observed and suspected hazards;

Onsite and offsite air and soil sampling results; and

Potential exposure pathways.

9.3. ESTABLISHMENT OF WORK ZONES

One of the basic elements of an effective site control program is the delineation of work zones at

the site. The purpose of establishing work zones is to:
