To stay hydrated during hot days in the workplace, employers must ensure a sufficient supply of drinking water is readily available to employees at no cost when the heat index equals or exceeds 80 degrees Fahrenheit [1]. The drinking water should be either cool or cold [1], with employees having the opportunity to drink up to 32 ounces per hour 2, 3. While electrolyte-replenishing beverages are acceptable substitutes, they should not completely replace water [1].

In addition to providing water, employers should train employees on the importance of frequent water consumption and the symptoms of dehydration 3, 4. Encouraging employees to stay hydrated is also crucial [2].

When the heat index reaches 90 degrees Fahrenheit, employers should implement high-heat practices, including a written heat illness prevention rest break schedule 2, 13. These rest breaks should occur in shaded areas or cool, climate-controlled areas 4, 5 to allow employees to cool down and recover [3].
