Heat Illness Prevention

water keeps you going

California employers are required to take these four steps to prevent heat illness:

  1. Training
    Train all employees and supervisors about heat illness prevention.
  2. Water
    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.
  3. Shade
    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.
  4. Planning
    Develop and implement written procedures for complying with the Cal/OSHA Heat Illness Prevention Standard.

The HIP Network is a voluntary public/private partnership established to increase both employers' and employees' awareness of the hazard of heat illness and the importance of heat illness prevention measures to prevent fatalities and serious illnesses in California workplaces.

HIP Network members work together to help prevent heat illness in workplaces throughout California in partnership with the Division of Occupational Safety and Health (Cal/OSHA) by providing timely and essential information to employers and employees.
