Heat Illness Prevention
California employers are required to take these four steps to prevent heat illness:
Train all employees and supervisors about heat illness prevention.
Provide enough fresh water so that each employee can drink at least 1 quart per hour, or four 8 ounce glasses, of water per hour, and encourage them to do so.
Provide access to shade and encourage employees to take a cool-down rest in the shade for at least 5 minutes. They should not wait until they feel sick to cool down.
Develop and implement written procedures for complying with the Cal/OSHA Heat Illness Prevention Standard.
