645 Heat Injury and Illness Prevention: Employee Skip to main content

Key Components of the HSMP

Scheduled and Symptom-Based Rest Breaks

The HSMP specifies required scheduled rest breaks to reduce heat stress. Additional breaks must be provided promptly if workers show symptoms such as dizziness, heavy sweating, or confusion.

Shaded or Cool Rest Areas

Employers must provide shaded or climate-controlled rest areas where workers can recover and lower their body temperature during breaks.

Engineering, Administrative Controls, and PPE

To mitigate heat exposure, the HSMP identifies:

  • Engineering controls (e.g., cooling stations, ventilation systems, covered areas)
  • Administrative controls (e.g., scheduling work for cooler parts of the day, task rotation)
  • Personal Protective Equipment (PPE), such as cooling vests or moisture-wicking clothing

Worker Monitoring System

The program details monitoring methods, such as using the "buddy system," where coworkers observe each other for signs of heat-related stress or illness. This proactive approach ensures quick action can be taken if needed.

Employee Roles and Responsibilities

Clear definitions of each employee's responsibilities and expectations for program participation are outlined. This ensures everyone understands their role in maintaining workplace safety.

Heat Stress Training

Regular training sessions educate workers on:

  • Recognizing heat-related illnesses
  • Proper hydration and nutrition
  • Effective use of rest breaks and cooling techniques
  • Procedures during heat-related emergencies

Annual Review and Program Updates

The HSMP must undergo an annual review to incorporate feedback, evaluate effectiveness, and update procedures as necessary to respond to changing conditions or new insights from workplace experiences.

The "buddy system" ensures quick action can be taken if a worker shows signs of heat-related stress or illneess.
