Supervisor and Competent Person Training

Policies and Procedures for Monitoring and Emergency Response

As part of the HSMP, supervisors and competent persons must be designated and receive thorough training — both on the program’s policies and procedures, and on how to monitor heat conditions and respond to heat-related emergencies. This training ensures they can effectively protect employees and manage heat stress risks in the workplace.

Supervisor Training

Before supervising employees working in a hot work environment, supervisors must be trained to:

  • Implement Program Procedures: Apply all site-specific heat-stress controls and work-rest schedules.
  • Recognize & Respond to Heat Illness: Detect early signs of heat stress, initiate emergency response, and summon first aid when needed.
  • Monitor Heat Conditions: Read weather reports, interpret heat alerts (WBGT or Heat Index), and adjust operations accordingly.
  • Reinforce Employee Training: Understand the employee heat-stress training curriculum (including hydration best practices) and ensure it's being followed on the job.
Supervisors and heat safety coordinators must be designated and thoroughly trained on the HSMP policies and procedures.
