OSHA Water Requirements for Heat: How Much and How Often

The 1 Quart Rule

OSHA recommends providing at least one quart of cool water per employee per hour.

Temperature Matters

Water needs to be cool (50-60°F). Warm water does not cool the body effectively and discourages drinking.

Distance is Key

If a worker has to walk 5 minutes to get water, they won't drink enough. Keep coolers close.
