An incident generally involves the escape of normally controlled substances and response activities involve actions to minimize and prevent these discharges. Site Control is preventing or reducing the exposure of any person and the transfer of hazardous substances (contaminants) from the site by civilians, department members and equipment. Site control involves two major activities:
A. Physical arrangements and control of site work areas.Control is needed to reduce the possibility of transport from the site of contaminants, which may be present on personnel and equipment. This can be accomplished in a number of ways including:
B. The removal of contaminants from people and equipment.
A. Establishing physical barriers to exclude the public and unnecessary personnel.
B. Establishing checkpoints with limited access to and from the site, or areas within the site.
C. Minimizing personnel and equipment on-site consistent with effective operations.
D. Establishing containment zones.
E. Undertaking decontamination procedures.
F. Conducting operations in a manner to reduce possibility of contamination.
