Cal/OSHA Reminds Employers to Protect Outdoor Workers from Heat Illness

Fresno—Temperatures at outdoor worksites across California continue to elevate as the weather warms up. Cal/OSHA today participated in a news conference, reminding employers to plan for and prevent heat illness in order to protect outdoor workers from heat-related illness and death.

An essential component of Cal/OSHA’s heat illness prevention model includes annual training statewide in both English and Spanish. Today, Nisei Farmers League and nine other agricultural employers co-sponsored training sessions in Easton in both languages. This co-sponsored training has been held every year since 2008 to highlight the need to protect outdoor workers from heat illness and the requirements under California’s heat illness prevention standard.

Heat illness is a serious hazard for people who work outdoors. Cal/OSHA’s prevention approach includes targeted enforcement inspections at outdoor worksites in industries such as agriculture, landscaping, and construction during the heat season.

These inspections ensure compliance with the heat illness prevention standard and the injury and illness prevention standard, which require employers to take the following basic precautions:

  1. Train all employees and supervisors on heat illness prevention;
  2. 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. 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. Shade structures must be in place upon request or when temperatures exceed 80 degrees Fahrenheit;
  4. Closely observe all employees during a heat wave and any employee newly assigned to a high heat area. Lighter work, frequent breaks or shorter hours will help employees who have not been working in high temperatures adapt to the new conditions; and
  5. Develop and implement written procedures for complying with the Cal/OSHA heat illness prevention standard, including plans on how to handle medical emergencies and steps to take if someone shows signs or symptoms of heat illness.

The most frequent heat-related violation that Cal/OSHA cites during enforcement inspections is for failure to have an effective, written heat illness prevention plan specific to the worksite. Serious heat-related violations are often related to inadequate access to water and shade, and to a lack of supervisor and employee training.

To remain in compliance with the standard, Cal/OSHA encourages employers and supervisors to learn more about the standard, which was amended in 2015. Please refer to the Cal/OSHA guidance on the new requirements and the Heat Illness Prevention Enforcement Q&A for more information on the updates.

Cal/OSHA also has extensive multilingual materials for employers, workers, and trainers on its Water. Rest. Shade. public awareness campaign website.
