Heat Illness Prevention

In California, employers must take steps to protect workers from heat illness in both indoor and outdoor workplaces under California Code of Regulations, Title 8 (T8CCR), sections 3395 and 3396. Employers may be covered under both the indoor and outdoor regulations if they have both indoor and outdoor workplaces.

Prevention Starts Here: Keep Your Crew Safe in the Heat

It is mandatory to train both employers and employees that are engaged in outdoor activities conducted in hot weather about the seriousness and prevention of Heat Illness, which includes Heat Exhaustion, Heat Stroke, and even death.

Requirement to prevent heat illness for employees

Training:

Teaching employees and supervisors about heat illness prevention, signs, symptoms, and emergency response procedures

Water:

Providing access to fresh, cool drinking water so employees can drink at least 32 ounces per hour

Shade:

Providing access to shade when temperatures are high or employees request it

Rest:

Allowing employees to take cool-down rest breaks in the shade

Planning:

Developing and implementing a written heat illness prevention plan

Monitoring:

Observing employees for signs of heat illness and keeping records of temperature conditions

Communication:

Establishing methods for employees to contact a supervisor when needed

Emergency response:

Preparing to transport employees to emergency medical care if needed

Heat Stress Safety Kits

A heat stress safety kit is important because it provides readily available tools and supplies to quickly address heat-related illnesses like heat exhaustion or heatstroke in the event a worker experiences symptoms while working in hot environments, allowing for immediate first aid and potentially preventing serious complications or fatalities; this is especially crucial in workplaces with high heat exposure where early intervention is critical.

Key points about heat stress safety kits

CST-heat_img1

Immediate cooling options:

Kits typically contain cold packs, ice packs, or cooling towels which can be applied to the body to rapidly lower core temperature in case of heat stress.

CST-heat_img2

Hydration support:

Electrolyte replacement drinks or powders are often included to help replenish fluids and minerals lost through heavy sweating.

CST-heat_img3b

Information and guidance:

Heat stress safety kits may also contain educational materials on recognizing heat stress symptoms, proper response actions, and preventative measures.

Shade

According to most workplace safety regulations, including those from OSHA, employers must provide access to shade for outdoor workers when the temperature exceeds 80 degrees Fahrenheit, and this shade should be readily available near the work area, large enough to accommodate all employees on break, and accessible upon request even if the temperature is below 80 degrees; essentially, shade must be present when it's hot enough to pose a heat-related risk to employees.

Indoor workplaces

The standard applies to indoor workplaces where the temperature is 82°F or higher
Employers can use air conditioning or fans to cool the workplace
Employers can provide personal heat protective equipment, like cooling vests

Outdoor workplaces

Employers must provide shade when temperatures are 80°F or higher
Employers must provide enough water so employees can drink at least 32 ounces per hour

Key points about shade regulations on jobsites

CST-heat-icon1

Temperature threshold: Shade is typically required when the temperature reaches 80 degrees Fahrenheit or above.

CST-heat-icon2

Accessibility: Shade should be located close to the work area where employees can easily access it during breaks.

CST-heat-icon3b

Capacity: The shade area must be large enough to comfortably accommodate all employees who need to cool down at the same time.

CST-heat-icon4b

Request access: Even if the temperature is below 80 degrees, employers should still provide access to shade if requested by an employee.

What constitutes "shade"

Canopies or tents erected specifically for shade
CST-heat-shade3
Buildings or other structures with shaded areas

Important considerations

Monitoring weather:

Employers should monitor weather forecasts to anticipate hot conditions and ensure adequate shade is available.

Employee training:

Workers should be educated on heat-related illnesses and the importance of utilizing shade when needed.

Cooling measures:

In extreme heat, employers may need to provide additional cooling measures like misting fans or cooling stations alongside shade.
