Heat Stress Monitoring Program Inspection Checklist [FREE PDF]

Heat stress is a leading cause of occupational illness and fatality, particularly in foundries, construction, agriculture, and outdoor industries operating in high-temperature environments. NIOSH and ACGIH have established Threshold Limit Values (TLVs) for heat stress based on wet bulb globe temperature (WBGT) and metabolic work rate, providing actionable thresholds for worker protection. OSHA's General Duty Clause (Section 5(a)(1)) requires employers to provide workplaces free from recognized h

  • Industry: Workplace Safety
  • Frequency: Daily
  • Estimated Time: 30-45 minutes
  • Role: Occupational Health Nurse
  • Total Items: 38
  • Compliance: OSHA General Duty Clause Section 5(a)(1) - Heat Illness Prevention, NIOSH Criteria for a Recommended Standard: Occupational Exposure to Heat and Hot Environments (2016), ACGIH TLV for Heat Stress and Heat Strain (Annual TLV Booklet), OSHA 29 CFR 1910.1020 Access to Employee Medical and Exposure Records, OSHA 29 CFR 1910.151 Medical Services and First Aid

Environmental Heat Monitoring

Measure and document environmental heat stress indicators including WBGT, dry bulb temperature, and humidity.

  • Has a calibrated WBGT meter been used to measure wet bulb globe temperature in the work area?
  • What is the current WBGT reading in the primary work zone?
  • What is the current dry bulb (ambient air) temperature in the work area?
  • What is the current relative humidity in the work area?
  • Has the heat index been calculated and posted for workers and supervisors to review?
  • Please upload a photo of the WBGT meter or heat monitoring station setup.

Heat Acclimatization Program

Verify that a structured acclimatization program is in place and being followed for new and returning workers.

  • Is a written heat acclimatization schedule in place for new workers entering heat-exposed jobs?
  • Are returning workers (absent >9 days) re-acclimatized before returning to full heat exposure?
  • Are acclimatization records maintained for each heat-exposed employee?
  • Has a supervisor been designated to oversee and enforce the acclimatization schedule on this shift?
  • Are new workers excluded from high-metabolic-rate tasks during their first week in heat-exposed conditions?

Hydration & Rest Break Controls

Confirm that adequate hydration stations and structured rest breaks are provided and monitored.

  • Are cool drinking water stations (≤59°F / 15°C) available within 50 feet of all heat-exposed workers?
  • Are electrolyte replacement drinks or salt supplements available for workers sweating heavily for extended periods?
  • Are scheduled rest breaks being taken in shaded or air-conditioned rest areas during high-heat conditions?
  • Is a buddy system in place so workers are actively monitoring each other for heat illness symptoms?
  • Have workers been trained to recognize personal signs of heat exhaustion and heat stroke?

Engineering & Administrative Controls

Assess the effectiveness of engineering controls such as ventilation, cooling, and task scheduling to reduce heat exposure.

  • Are general and local exhaust ventilation systems operating effectively in heat-generating work areas?
  • Are radiant heat sources shielded or insulated where feasible?
  • Are high-heat tasks scheduled during cooler parts of the shift or day?
  • Are cooling vests, ice packs, or other personal cooling equipment available for workers in extreme heat areas?
  • Is a heat alert system in place to trigger additional controls when WBGT or heat index exceeds action thresholds?

Medical Surveillance & Emergency Preparedness

Verify that medical surveillance protocols and emergency response plans for heat emergencies are current and functional.

  • Is a written medical emergency response plan for heat illness (heat exhaustion and heat stroke) posted and accessible?
  • Are first aid supplies including ice packs, cold water immersion capability, or cold towels available on-site?
  • Are at-risk employees (age >60, obesity, cardiac conditions, medications) identified and receiving enhanced monitoring?
  • Are heat illness incidents and near-misses being reported and investigated?
  • Has local emergency services (EMS) contact information been verified and posted at all work sites?
  • Have supervisors completed OSHA heat illness prevention training within the past 12 months?

Heat-Related PPE Assessment

Evaluate appropriateness and availability of clothing and PPE that affects heat load on workers.

  • Are workers wearing the minimum amount of clothing appropriate for the heat environment while meeting safety requirements?
  • Have clothing adjustment factors (CAF) been applied to WBGT calculations for workers wearing impermeable or multilayer garments?
  • Is cooling PPE (e.g., cooling vests, phase-change cooling garments) available and maintained for high-heat tasks?
  • Are workers' clothing and PPE selections reviewed by the occupational health professional for heat load compatibility?
  • Please upload a photograph of the primary work area showing current worker PPE and environmental conditions.

Program Documentation & Recordkeeping

Confirm that all heat stress program records, training logs, and monitoring data are properly maintained and accessible.

  • Is a written heat illness prevention program document current, signed by management, and accessible to all employees?
  • Are daily WBGT and environmental heat monitoring records being retained and archived?
  • Are worker heat illness training records (dates, topics, signatures) current and filed for all heat-exposed employees?
  • Have any heat illness incidents this season been recorded on the OSHA 300 Log?
  • Is the heat stress program scheduled for annual review and update by the occupational health team?
  • Please document any program deficiencies, corrective actions assigned, or follow-up items identified during this inspection.
