Perform Job Breifing

PIC Conducts the Job Briefing. Cover all the contents of the Job Safety Plan.

A Job Briefing at a minimum must include:
  1. Detailed Scope of Work
  2. Shock and arc flash hazards for each task
  3. Controls to mitigate the hazards (procedures, precautions, energy source controls, PPE requirements)
  4. Work area controls (barricades, signs, attendants)
  5. Emergency Response Plan
