Heat Illness Prevention Campaign

OSHA's Heat Illness Prevention campaign, launched in 2011, educates employers and workers on the dangers of working in the heat. Through training sessions, outreach events, informational sessions, publications, social media messaging and media appearances, millions of workers and employers have learned how to protect workers from heat.

This webpage provides information on working in outdoor and indoor heat environments, including planning for heat events, supervision of employees, heat-related illness symptoms and first aid, prevention of heat illness, important personal risk factors for consideration, relevant OSHA standards, case studies, information on worker's rights, and additional resources on this topic.
