California’s Indoor Heat Illness Prevention Standard Approved: What You Need to Know

Recently, the Cal/OSHA Standards Board approved new requirements for California businesses, heat illness prevention for indoor work spaces. The new Section 3396 addition to the California Labor Code will go into effect as early as August 1, 2024.

 The law states that requirements apply to “all indoor work areas where the temperature equals or exceeds 82 degrees Fahrenheit when employees are present.”

 For work environments such as warehouses, restaurants, and manufacturing plants, temperatures can rise dangerously high, putting employees at risk for heat illness. Let’s take a look into the new requirements for employers. 

1. Provide access to cool-down areas, and encourage employees to take cool-down rests.

2. Provide access to potable water that is fresh, suitably cool, free of charge, and located as close as possible to indoor cool-down area.

3. Monitor employee symptoms and provide appropriate first aid and emergency response if they exhibit or report signs of heat illness.

4. Closely observe new employees for the first 14 days of employment as they acclimatize.

5. Provide employees and supervisors with training on topics such as heat risk factors, symptoms of heat illness, water consumption, and emergency procedures.

6. Establish, implement and maintain a written Heat Illness Prevention plan for the work environment.

Some additional requirements also apply when the temperature or heat index reaches or exceeds 87 degrees while employers are present, or the temperature reaches or exceeds 82 degrees and employees wear clothing that restricts heat removal or they work in a high radiant heat area.

 In these cases, employers need to maintain records of their indoor temperature or heat index. They also must initiate engineering, administrative, and personal control measures to reduce the indoor working environment and maintain it below 87 degrees.

 As temperatures continue to soar in many parts of California, employers with employees working indoors in high heat conditions should evaluate their current heat policies to ensure they comply with these impending labor law changes.

 For further information about indoor heat illness prevention compliance, clients should refer to the Cal/OSHA website, which offers resources employers can utilize, including a Sample Written Heat Illness Prevention Plan for Indoor and Outdoor Places of Employment (Model Program).
