Fall Protection – Heat Stroke Hazard in Construction

fall protection, safety equipmentAnother reason it is important to have proper fall protection equipment and safety equipment is the heat. Heat is a serious hazard in construction. Your body builds up heat when you work and sweats to get rid of extra heat. But sometimes your body may not cool off fast enough. This can happen, say, if you are up on a roof pouring hot asphalt or you are lifting heavy loads. Too much heat can make you tired, hurt your job performance, and increase your chance of injury. You can get skin rash. You can also get:

• Dehydration. When your body loses water, you can’t cool off fast enough. You feel thirsty and weak.

• Cramps. You can get muscle cramps from the heat even after you leave work.

• Heat exhaustion. You feel tired, nauseous, headachy, and giddy (dizzy and silly). Your skin is damp and looks muddy or flushed. You may faint.

• Heat stroke. You may have hot dry skin and a high temperature. Or you may feel confused. You may have convulsions or become unconscious. Heat stroke can kill you unless you get emergency medical help.

The Risk of Heat Stress

 Your risk of heat stress depends on many things. These include:

• Your physical condition

• The weather (temperature, humidity)

• How much clothing you have on

• How fast you must move or how much weight you must lift

• If you are near a fan or there is a breeze

• If you are in the sun.

If there is an industrial hygienist on your work site, ask the hygienist about the Wet-Bulb Globe Temperature Index. It is a more precise way to estimate the risk of heat stress.

Protect Yourself

Try to do these things:

• Drink when you are thirsty.

• Keep taking rest breaks. Rest in a cool, shady spot. Use fans.

• Wear light-colored clothing made of cotton.

• Do the heaviest work in the coolest time of the day.

• Have the proper rigging and fall protection equipment in place, so if you do pass out you don’t hurt yourself further.

• Work in the shade

• For heavy work in hot areas, take turns with other workers, so some can rest.

• If you travel to a warm area for a new job, you need time for your body to get used to the heat. Be extra careful the first 2 weeks on the job.

• If you work in protective clothing, you need more rest breaks. You may also need to check your temperature and heart rate. On a Superfund site where the temperature is 70 degrees or more, the U.S. Environmental Protection Agency (EPA) writes that while on the job you should be monitored for heat-stress related symptoms, including changes in body temperature and heart rate.

• If you think someone has heat stroke, call emergency services (or 911). Immediately move the victim to the shade. Loosen his/her clothes. Wipe or spray his/her skin with cool water and fan him/her. You can use a piece of cardboard or other material as a fan. OSHA does not have a special rule for heat. But because heat stress is known as a serious hazard, and important reason to use fall protection workers are protected under the General Duty Clause of the Occupational Safety and Health Act. The clause says employers must provide “employment free from recognized hazards…causing or…likely to cause physical harm.”
