Site Safety and Health Plans, Incident Command, and Worker Roles
The exam tests whether you can connect the Site Safety and Health Plan, the Incident Command System, and worker roles without confusing them.
Core rules
- A HASP under 29 CFR 1910.120(b) identifies site hazards, control measures, PPE, air monitoring, decontamination, medical surveillance, emergency response, and training.
- ICS uses common terminology, a manageable span of control, and clear chain of command. The incident commander sets objectives; operations, planning, logistics, and finance/administration carry them out. Unified command coordinates multiple agencies.
- Worker roles include the site safety and health officer, site supervisor, authorized entrant, attendant, entry supervisor, competent person, and buddy.
- Stop-work authority belongs to workers who see an imminent danger; they should alert others and notify the supervisor or safety officer.
- The HASP is a living document; update it when conditions, tasks, or contaminants change.
Worked example
A subcontractor begins hot work beside a fuel storage area. A worker sees the activity and knows the HASP requires a permit and fire watch. The reasoning is: use stop-work authority, move people away, notify the site safety officer and supervisor, and do not restart until the permit, fire watch, and fuel isolation are in place. The worker does not need to be the incident commander to act.
Traps that cost marks
- Confusing the incident commander with the site safety and health officer.
- Treating the HASP as paperwork that never changes.
- Believing only supervisors can stop work.
- Ignoring unified command when multiple agencies respond.
