Under Title 8 CCR §3395 (Heat Illness Prevention), when the outdoor temperature exceeds 95°F, the employer must implement 'high-heat procedures' for affected workers in identified industries (including construction). These procedures include:

Explanation

Section 3395(e) requires, to the extent practicable: effective communication so employees at the site can contact a supervisor; observing employees for alertness and signs of heat illness, by supervisor or designee observation of 20 OR FEWER employees, a mandatory buddy system, regular communication with a sole employee, or other effective means; designating one or more employees authorised to call emergency medical services; reminding employees throughout the shift to drink plenty of water; and a pre-shift meeting reviewing the high-heat procedures. Option (a) inflates the real observation ratio from 20 to 50, which is exactly the kind of number an employer talks itself into. Option (b) is (e)(6), the ten-minute cool-down rest every two hours, which the standard gives to employees in AGRICULTURE and not to construction. Option (c) is invented: nothing in the section stops work at any temperature.
