Train workers before hot outdoor work begins. Tailor the training topic outline to cover employer-specific policies and worksite-specific conditions. A single worksite may have some job tasks that are low risk for heat-related illness and others that are high risk. Training will be more effective if it is matched to job tasks and conditions, and is reviewed and reinforced throughout hot weather conditions. The following training topics may be addressed in one session or in a series of shorter sessions.
|Factors that May Cause Heat-related Illness|
See Training Resources for heat-related illness prevention training tools and resources. Also see OSHA's Heat-Related Illness Prevention Training Guide (PDF*) for one tool to help you train your workers. The training guide includes instructions for teaching workers about heat hazards and a daily checklist to make sure all appropriate precautions are in place each workday. OSHA's factsheets and worksite posters (in English and Spanish) can help in communicating key messages about heat safety and health. Some labor and industry organizations offer industry-specific guidance for protecting workers, such as wildland firefighters (PDF), that face heat exposure under special circumstances. Inquire whether your industry offers any special guidance, or adapt information from industries with similar situations.
|Heat Index||Risk Level||Protective Measures|
|Less than 91°F||Lower (Caution)||Basic heat safety and planning|
|91°F to 103°F||Moderate||Implement precautions and heighten awareness|
|103°F to 115°F||High||Additional precautions to protect workers|
|Greater than 115°F||Very High to Extreme||Triggers even more aggressive protective measures|
How can OSHA help? Workers have a right to a safe workplace. If you think your job is unsafe or you have questions, contact OSHA at 1-800-321-OSHA (6742). It's confidential. We can help. If you have been punished or discriminated against for using your rights, such as raising health and safety concerns or filing a complaint, you must file a complaint with OSHA within 30 days. No form is required, but you must call or send a letter to OSHA within 30 days of the alleged discrimination.
