Heat Stress Monitoring Program Inspection Checklist [FREE PDF]

Heat stress is a significant occupational hazard governed by OSHA's General Duty Clause (Section 5(a)(1) of the OSH Act) and detailed guidance from NIOSH Criteria for a Recommended Standard: Occupational Exposure to Heat and Hot Environments (DHHS 2016-106). The ACGIH Threshold Limit Values (TLVs) for Heat Stress and Heat Strain provide specific Wet Bulb Globe Temperature (WBGT) action limits based on workload and acclimatization status. Employers in industries such as construction, manufacturin

Environmental Heat Monitoring

Measure and document ambient environmental heat conditions using validated instruments to compare against action limits.

Has the Wet Bulb Globe Temperature (WBGT) been measured using a calibrated WBGT instrument at the work site?
What is the current measured WBGT value at the primary work location (°F)?
Is the ambient air temperature measured and recorded at the beginning and midpoint of each shift?
Is relative humidity measured and documented alongside temperature readings?
Has the NWS Heat Index or equivalent heat advisory been checked before the start of outdoor work today?
Is radiant heat from machinery, furnaces, or solar exposure accounted for in the WBGT or heat index assessment?

Acclimatization Program

Verify that a structured acclimatization schedule is implemented for new and returning workers exposed to heat.

Is a documented acclimatization schedule in place for all new workers assigned to heat-exposed tasks?
Are workers returning from absence of 9 or more days treated as unacclimatized and placed on a modified schedule?
Are supervisors trained to identify when new workers may be struggling with acclimatization and intervene appropriately?
Are acclimatization schedules and worker compliance records maintained in writing?
Are workers with known medical conditions that increase heat susceptibility (cardiovascular disease, diabetes) identified and medically cleared?

Hydration and Rest Break Program

Confirm that adequate hydration resources and structured rest periods are provided and enforced during heat-exposed work.

Is cool potable water (ideally 50–60°F) available within 300 feet or a 1-minute walk of all heat-exposed work areas?
Are workers instructed to drink approximately 8 ounces of water every 15–20 minutes regardless of thirst?
Are structured rest breaks provided in shaded or cool areas, with duration and frequency matching current heat index levels?
Are electrolyte replacement options (sports drinks, electrolyte tablets) available for workers sweating heavily for extended periods?
Is a buddy system in place to ensure workers are monitoring each other for signs of heat illness during rest periods?

Engineering and Administrative Controls

Verify implementation of hierarchy-of-controls measures to reduce heat exposure at the source and through work practice modifications.

Are engineering controls (air conditioning, cooling fans, evaporative coolers, shade structures) implemented in high-risk areas?
Are hot jobs or highest-exertion tasks scheduled for cooler parts of the day (early morning or evening) where possible?
Is the work-rest schedule adjusted in real-time based on changes in WBGT or heat index throughout the shift?
Are workers prohibited from working alone in high-heat conditions (heat index above 103°F)?
Is cooling PPE (cooling vests, wet towels, cooling neck wraps) available and used by workers in very high heat environments?

Heat Illness Recognition and Emergency Response

Confirm that workers and supervisors can identify heat illness symptoms and that a site-specific emergency action plan is active.

Are all supervisors trained to recognize the symptoms of heat cramps, heat exhaustion, and heat stroke?
Is a written site-specific Emergency Action Plan (EAP) for heat illness posted and communicated to all workers?
Is an ice bath, cold water immersion tub, or cooling station available on-site for rapid cooling of heat stroke victims?
Do first aid responders know that a heat stroke victim should be cooled aggressively BEFORE EMS arrival?
Are heat illness incidents, near-misses, and medical aid cases documented and reviewed for program improvement?

Medical Surveillance and Health Screening

Verify that pre-placement and periodic health assessments are conducted for workers at elevated heat stress risk.

Are pre-placement medical evaluations conducted for workers assigned to high-heat environments?
Are periodic medical assessments conducted for workers with ongoing heat exposure, including heart rate and core temperature monitoring?
Are medical records for heat-exposed employees maintained and retained per OSHA 1910.1020 requirements?
Are employees taking medications known to impair heat tolerance (diuretics, antihistamines, beta-blockers) identified and monitored more frequently?
Are workers who experience heat illness referred for medical evaluation before returning to heat-exposed duties?

Training and Program Documentation

Confirm that training records, program documentation, and regulatory notifications are current and complete.

Have all workers exposed to heat hazards received heat illness prevention training in a language they understand?
Do training records document the date, trainer, topics covered, and worker signatures for all heat stress training sessions?
Is the written Heat Illness Prevention Plan reviewed and updated at least annually or after any heat-related incident?
Are heat monitoring logs, acclimatization records, and incident reports retained on file for regulatory inspection?
Additional observations, corrective actions needed, or notes from today's heat stress monitoring inspection?
