Site Map

A site map (see image) showing topographic features, prevailing wind direction, drainage, and the location of buildings, containers, impoundments, pits, ponds, and tanks is helpful in:

Site Map
  • planning activities
  • assigning personnel
  • identifying access routes, evacuation routes, and problem areas
  • identifying areas of the site that require use of personal protective equipment
  • supplementing the daily safety and health briefings of the field teams

The map should be prepared before site entry and updated throughout the course of site operations to reflect:

  • accidents
  • changes in site activities
  • emergencies
  • hazards not previously identified
  • new materials introduced on site
  • vandalism
  • weather conditions

Overlays can be used to help portray information without cluttering the map.
