Handle the Heat

Overview
Working in the heat puts an extra strain on your body. With some understanding of how the body reacts to heat, you can prevent heat-related disorders.

What are the risk factors?
Personal:
Age, weight, degree of physical fitness, metabolism, medications, use of alcohol or drugs, water consumption, caffeine consumption, and a variety of medical conditions, such as hypertension, all affect a person's sensitivity to heat. It is difficult to predict who will be affected by the heat, or when someone will be affected.

Environmental:
Air temperature; humidity; radiant heat from the sun and other sources; conductive heat sources, such as the ground, air movement, workload severity and duration; protective clothing; and PPE are all other factors to consider.

Another factor is whether or not you are accustomed to the heat. By gradually being exposed to working in hot conditions, your body develops a greater tolerance for the heat.

Can personal protective equipment add to the hazard?
Yes, sometimes heavy or impermeable chemical protective clothing can contribute to a worker's exposure to the heat. However, there are specialized types of PPE that can be worn under other types of protective clothing to cool workers, such as Ice vests, water-cooled garments, and air supply systems.

Work practices can help control heat hazards
A more common technique that might be considered PPE is to wear wet clothing, headbands, or bandanas. This could also be considered a type of work practice control. Other work practices that help control exposure to the heat include:
- Using intermittent rest periods to recover from the heat.
- Drinking about 5 to 7 ounces of fluids every 15 to 20 minutes to replenish body fluids.
- Using relief workers.
- Using the buddy system (work in pairs) when working in hot conditions.
- Pacing the work, or reducing the physical demands of the work.
- Providing cool recovery or shaded rest areas.
- Scheduling work for cooler times of the day or when heat producing equipment isn't being operated.
- Wearing light, loose-fitting, breathable (like cotton) clothing.
