Health and Safety Plan (HASP)

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.

The following information is useful in developing and implementing a site control program:

  • a site map that shows work zone boundaries and identify how these boundaries will be visibly marked on the site. These boundaries may change as work operations change or if hazards migrate to clean areas.
  • 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.
