It may not be the dog days of summer yet, but you would never know it. The climate outlook for the month of July, according to NOAA’s Climate Prediction Center, is that temperatures will be well above average across much of the country, spanning the Mountain West to the East Coast.

For service technicians, summer not only means dealing with increased pest pressure and full routes but dealing with the heat found in crawlspaces and attics. Knowing the signs of heat-related illnesses and training employees on ways to reduce their exposure to excessive heat can head off problems.

Heat Related Illnesses

Problems develop when the body’s cooling mechanisms do not work properly. For example, when the air temperature exceeds body temperature, the body cannot easily cool itself. If the air is humid, sweat also does not evaporate quickly. Sweat also does not evaporate from a person wearing protective gear making heat-related illness a concern in any weather, anywhere.

Heat-related illness takes several forms. Heat rash occurs when sweat ducts become clogged. Heat cramps are painful muscle spasms caused by the loss of electrolytes from heavy sweating. If you develop these conditions, immediately get out of the heat so you can rest.
