Site Control

Another important element of the HASP is site control, which involves controlling the activities of employees and the movement of equipment which minimizes potential contamination of employees. Site control also protects the general public from site hazards and can prevent trespassing and vandalism.

Site control procedures should:

  • identify contaminated areas and appropriate work practices,
  • address preventing unauthorized or unprotected workers from entering contaminated areas, and
  • define controlling the migration of site contaminants.

A site map that shows work zone boundaries and identifies how these boundaries will be marked on the site is helpful in developing and implementing a site control program. These boundaries may change as work operations change or if hazards migrate to clean areas.

Here is some other useful information when developing and implementing a site control program:

  • site work zones and site communication procedures for each work zone;
  • methods for controlling entry into contaminated areas, restricting this to authorized employees who are properly trained and protected;
  • safe work practices; and
  • the name, location, and phone number of the nearest medical assistance.
