Water should have a palatable (pleasant and odor-free) taste and water temperature should be 50°F to 60°F, if possible.
Encourage workers to choose water over soda and other drinks containing caffeine and high sugar content. These drinks may lead to dehydration. Drinks with some flavoring added may be more palatable to workers and thereby improve hydration. Encourage workers to avoid drinking alcohol during hot weather events.
At the moderate risk level some precautions in addition to those already mentioned are needed to prevent heat-related illness. Review heat-related illness signs and precautions with workers. Remind workers to drink water. Provide workers opportunities to rest in cool, shaded areas. Be aware of conditions that could increase risk.
Workers who show symptoms of heat-related illness need immediate attention. Treating milder symptoms (headache, weakness) early by providing rest in a shaded area and cool water to drink can prevent a more serious medical emergency. Call 911 immediately if a worker loses consciousness or appears confused or uncoordinated. These are signs of possible heat stroke. Heat stroke is fatal if not treated immediately.
The resources under Educational Resources are useful training tools for daily meetings and toolbox talks.
|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|
