Safety Tips For Working In The Heat

As we begin to move from cool spring time weather into the hotter summer months it is important to remember that remaining hydrated and watching out for heat-related illnesses is very important. Working in hot conditions whether it be indoors or outdoors can create a variety of health conditions that can range from mild to severe. The human body maintains on average a temperature of about 98.6 degrees Fahrenheit. When that temperature rises, the body begins to sweat which in turn acts as a mechanism to cool the body down. However, if it is too hot outside the sweat will not evaporate thus resulting in the body not being able to cool off. The body will then begin to experience discomfort and demonstrate signs of distress. 

Factors that increase the risk of overheating:

  • Physical exertion

  • Being unaccustomed to working in the heat

  • Wearing too much clothing

  • Old age

  • Being overweight

  • Various medications

  • Alcohol consumption

Once any of the signs and/or symptoms listed below are noticed, it is very important to administer the necessary treatment as soon as possible. If conditions continue to worsen then medical attention must be sought out immediately.

  • Pale and clammy skin

How to prevent heat stress at work:

Heat safety Tips

  • When working in hot environments, regardless of where, there should always be an adjustment period to acclimate to the heat.

  • Only well-balanced meals should be consumed and alcohol as well as caffeine should be avoided. Eating heavy and/or hot foods are not a good idea either.

  • More importantly though, one should drink plenty of water to remain hydrated. About 16-32 ounces of water per hour is recommended while working in the heat.

  • To minimize overexertion, work should be kept at a steady pace with regular breaks in a cool or ventilated area.

  • When outside, the most strenuous work should be scheduled for the coolest part of the day.

  • Loose, lightweight and light-colored clothes should be worn. A hat and sunscreen can be helpful as well.

  • When inside, there should be some sort of general ventilation, cooling fans, and evaporative cooling utilized whenever possible.

Always be aware of your body and know your limitations to work safely in the heat.
