Heat illness prevention plan template for US worksites

A heat illness prevention plan should tell workers and supervisors exactly how this site will recognize hazardous heat, change the work, provide water and cooling, protect new or returning workers, and respond immediately when someone becomes ill. A generic promise to “take breaks as needed” is too vague to run a hot job safely. The fillable framework below is designed for both indoor and outdoor work. Adapt it to the actual state, site, workforce, task and weather, then brief people and test the emergency response before heat exposure begins.

This is a planning template, not a claim that every entry is a current federal regulatory requirement. OSHA's heat standards page distinguishes current federal duties and state heat standards. Its federal heat rulemaking page still describes an outdoor and indoor heat rule as proposed at this review date. Do not present proposed triggers or the proposed plan text as a final rule. Existing duties, including the Occupational Safety and Health Act's General Duty Clause where applicable, still matter. State and local requirements may be more specific: OSHA identifies heat standards in California, Colorado, Minnesota, Oregon and Washington, while its 2026 enforcement directive also discusses Maryland and Nevada. Check the current regulator for *each site* before selecting thresholds, breaks, written-plan, training or record requirements. A single US-wide temperature number is not a safe substitute.

The existing Complys US heat-illness guide gives a short explanation of prevention. This page has a different task: a blank, usable site plan with decision fields, daily implementation checks and an emergency card. If current repository review finds the live guide already contains this full form, integrate it there rather than creating a competing URL.

1. Identify the plan and its scope

The named lead needs authority to change work, add rest, relocate people or stop the task. A plan held by an office manager who cannot reach the shift supervisor will not control exposure. For temporary or subcontracted labor, agree who provides water, shade or cooling, training and emergency direction at the site, and how each employer checks that its workers are protected. OSHA's staffing-agency and host-employer heat bulletin emphasizes coordination, particularly for new workers.

2. Assess heat before and during the shift

Site assessment method: [Who checks forecasts, indoor/process conditions and the actual work area; what measurement or source is used; when checks occur; how results reach supervisors]. Record the site and timestamp, not only a weather app value for a distant town. Outdoor forecast or heat index can help, but it may miss radiant heat, direct sun and work intensity. Indoor heat from furnaces, kitchens or poorly ventilated rooms may be hazardous when outdoor weather looks mild. OSHA's technical heat chapter explains the combined influence of environment, workload, clothing and acclimatization.

Change trigger: [Who rechecks after a weather alert, increased physical demand, equipment/process change, heat-wave onset, worker symptoms or a cooling-system failure]. The plan should say what happens when conditions worsen mid-shift. Do not use a single number as a universal assurance that the work is safe below it; assess combined exposure and actual worker response.

3. Reduce exposure: work design, cooling, water and rest

First consider reducing heat at its source or changing the task: insulation or shielding from process heat, cooling/ventilation, moving strenuous work to a cooler time, mechanical assistance, task rotation and shorter exposure. Then set the site-specific water, rest and cooling arrangements. OSHA's water, rest and shade guidance recommends readily accessible cool water, regular drinking, breaks that increase with heat stress and a cool recovery location. Check the controlling state standard before writing exact mandatory amounts or intervals into the final plan.

A water cooler can run empty. A shaded corner beside a hot machine may not cool anyone. Give the supervisor a pre-start and mid-shift check, and a fallback if a control fails. Workers should be allowed to report symptoms, obtain a break and stop unsafe exposure without pressure to work through it. OSHA recommends not relying on thirst alone and making recovery areas easy to use.

4. Acclimatize and monitor new or returning workers

Who is covered: [New starters, workers new to this task/heat, people returning after an extended absence, temporary workers and others the assessment identifies]. Named supervisor: [Name]. Schedule: [A staged duration/workload and extra-break plan for the first days; current state-law requirement if applicable]. Buddy/check-in method: [Frequency, channel and what symptoms trigger removal from heat]. Record: [Daily exposure/adjustment, worker briefing, supervisor sign-off].

OSHA's new-worker guidance recommends gradual heat exposure and closer monitoring. It describes a “20 percent rule” for workers new to hot work as a prevention recommendation, not a universal legal formula that displaces a State Plan rule. Returning workers may need a different staged approach. Do not assume a physically fit new worker is already acclimatized. If the plan's schedule is disrupted by a heat wave, PPE change or extended absence, reassess before simply advancing the worker to a full hot shift.

Practical example: A warehouse brings in two temporary workers during a heat wave. The general temperature monitor is not enough. Their assignment lead should confirm the hot area, lighter first-day tasks, accessible cooling and fluids, symptom briefing, named check-in person and the host/agency reporting chain. If the cooling equipment fails, pause and redesign the work; a signature on the plan does not compensate for lost controls.

5. Train, communicate and give stop-work authority

Before exposure, train workers and supervisors in the site plan, heat-risk factors, water/rest/cooling arrangements, symptoms, how to summon help, emergency location details and how to report worsening conditions. Include people whose first language differs from the supervisor's; check understanding rather than collecting signatures alone. OSHA's planning guidance calls for a responsible person on site and a written plan, while its first-aid guidance describes symptoms and urgent action.

Supervisors need to recognize when a worker is struggling, not merely repeat a temperature threshold. The plan should instruct a worker to stop and tell someone promptly when symptoms occur, and a supervisor to remove the worker from heat and begin the emergency procedure.

6. Emergency response card: practice before the event

Call 911 immediately for confusion, slurred speech, collapse, unconsciousness or other signs of heat stroke. Start active cooling while help is coming. Do not leave the worker alone. OSHA's heat first-aid guidance says to move the person to a cooler area, remove outer clothing where practical, use cold water or ice and stay with them. Do not wait to decide whether the illness is “only heat exhaustion” when serious symptoms are present. The site plan needs a location-specific rescue path, not a generic “seek medical advice” sentence.

For a mobile crew, print or cache the exact address, gate and emergency contact in the vehicle or job packet. A worker on a rooftop may need a safe means of descent before responders can reach them; plan that with a competent person. Do not instruct an ill worker to drive themselves to a clinic or leave them to recover unattended.

7. Daily implementation and review log

A written plan becomes useful when a supervisor records the control decision and checks whether the controls exist. Keep the daily record proportionate, accessible to the shift, and linked to corrective action.

Review after: [A heat illness or near miss, worker report, failed water/cooling control, new task/PPE, changed state rule, seasonal start or significant weather change]. Record the corrected control, worker communication, approver and date. If an event meets recordkeeping or reporting criteria, use the proper federal or State Plan process; this plan is not a substitute for an OSHA report. Avoid collecting unnecessary personal medical detail in a broadly accessible heat log.

Before using this plan

1. Confirm whether this workplace is under federal OSHA, a State Plan or another sector-specific authority and insert the current local requirements. OSHA's state heat standards summary is a starting point, not a substitute for the controlling text.
2. Walk the actual tasks and work zones. Choose controls for indoor/process heat, outdoor sun and physical effort, not just the season's forecast.
3. Name people who can act, supply the water and cooling, set an acclimatization schedule, post the emergency card and rehearse reaching the worker and responders.
4. Brief every affected shift and make the current plan available where the work happens. Update it when conditions or rules change.
