Georgia’s hot and humid summers can make outdoor work conditions tough. But when does heat become dangerous for workers? It is important to understand OSHA (Occupational Safety and Health Administration) guidelines to help employers protect workers from heat-related illnesses.

OSHA’s guidelines 

OSHA does not set a maximum temperature for working outdoors but requires employers to take measures to prevent heat-related illnesses. The agency’s “Heat Illness Prevention” program emphasizes providing water, rest, and shade when temperatures rise. OSHA’s Heat Safety Tool app advises increased precautions when temperatures exceed 80°F and identifies temperatures above 90°F as particularly hazardous. 

Workers in industries like construction and agriculture face greater risks in such conditions. Employers are required under OSHA’s General Duty Clause to ensure that the workplace is free from recognized hazards, which include excessive heat.

The Effects of Heat 

Prolonged heat exposure can lead to heat exhaustion, heat stroke, and other serious health risks. In the summer, high heat combined with humidity makes it harder for workers to cool down. OSHA encourages employers to monitor the heat index, which factors in temperature and humidity. 

When the heat index exceeds 91°F, employers should take protective measures, and if it goes beyond 103°F, they may need to modify or stop work to avoid heat-related illnesses. Employers failing to take these measures can face OSHA fines or liability for work-related illnesses.

Safeguarding Workers 

Extreme temperatures can impact both productivity and worker safety, making proper heat management crucial. Employers should assess their specific work environments regularly to adjust strategies as needed. By taking proactive steps, businesses can mitigate risks and maintain a safe workplace throughout the summer.
