Supervision, Worker Safety, and Emergency Response
Supervisor duties
The supervisor runs the site-specific plan, verifies containment, directs work practices, controls access, and stops work when conditions are unsafe. The supervisor must be trained and licensed, understand the project design, and maintain daily logs, exposure records, and notification documents.
Safety and emergency response
- Brief workers on hazards, PPE, decon, and emergency signals.
- Keep a fire extinguisher, first-aid kit, and communication method available.
- For a containment breach, stop work, keep occupants out, repair the barrier, HEPA-vacuum, and document the event.
- For a spill, wet and cover the material, restrict access, and clean with HEPA equipment.
- Watch for heat stress, electrical hazards, falls, and confined spaces; abatement does not suspend other safety rules.
Worked example
A scrubber fails and the enclosure becomes positive relative to the occupied corridor. The supervisor should stop removal, evacuate nonessential workers, seal the opening, restore negative pressure with a backup scrubber, clean any release, and notify the building owner. Restarting work without correcting pressure and documenting the release is a serious error.
Traps
Do not let production pressure override containment; do not assume the supervisor may skip PPE; do not treat a small release as “no report.” Do not ignore heat stress in a sealed suit.
