Site Maps ✅The site map is an essential piece of the site control program. The map serves as a
central source of information about the site and can help personnel plan and organize
activities. By using the map, issues are identified, such as access and evacuation routes and
areas requiring the use of personal protective equipment (PPE). This makes the site map an
excellent resource and supplement for daily safety/health briefings of field teams. The site map
should be developed prior to the initial site entry using information from the preliminary
evaluation.
Site Preparation ✅The preparation of a site for clean-up activity is just as critical as the cleanup
itself. Proper preparation is necessary to ensure that emergency response operations go
smoothly and that workers are protected. If site preparation is not conducted properly, the
health of those doing the preparation as well as those doing the cleanup can be endangered.
Some major steps in site preparation include:
The construction of roadways
The elimination of physical hazards
Installing skid resistant strips on slippery surfaces
Site Work Zones ✅To reduce the spread of hazardous substances in a contaminated area, work
zones should be established. As many work zones can be established as are needed to meet
operational and safety objectives. Separate zones are created to distinguish different levels of
personal protective equipment, or PPE. To prevent cross-contamination, workers and
equipment should not be transferred between zones.
Establishing work zones ensures:
