Take Precautions to Prevent Heat Illness


Working outside, you know that the weather can have an impact on your day. Hot weather, especially when combined with strenuous physical labor, can cause your body temperature to rise to unsafe levels. Normally, your body cools itself through sweating, but in hot and humid weather, sweating is not enough, and the result can be a dangerous heat illness.


Staying Cool

Follow the suggestions below to stay cool when working in hot weather:

  • Wear loose, light-colored clothing when possible, along with a hard hat.

  • Take short breaks to rest in the shade. If wearing outer protective gear, remove during your break.

  • Gradually build up to heavier work.

  • Avoid overexerting yourself during peak temperature periods (midday).

  • Drink liquids frequently, even if you don’t feel thirsty - at least eight ounces every 20 to 30 minutes. Choose water, fruit juice, or sports drinks and stay away from liquids containing caffeine, which can dehydrate you.


Recognizing the Symptoms

There are three forms of heat illness, each with the following distinct symptoms:

  • Heat Cramps – severe muscle spasms in the back, stomach, arms, and legs, which are attributed to the loss of body salt and water during periods of heavy perspiration

  • Heat Exhaustion – Heavy sweating, cool or pale skin, nausea, headache, weakness, vomiting, and fast pulse

  • Heat Stroke – high body temperature, sweating stops, red and often dry skin, rapid breathing and pulse, headache, nausea, vomiting, diarrhea, seizures, confusion, or unconsciousness


Providing Treatment

It is essential to treat heat illness as soon as possible. If you are feeling any of the above symptoms, inform a co-worker and ask for help. If you suspect that a fellow worker has any of these conditions, follow the first-aid suggestions below:

  • Heat Cramps – Move the victim to a cooler area and allow them to drink approximately six ounces of water every 15 minutes. Follow up with a medical examination.

  • Heat Exhaustion – Move the victim to a cooler area and keep him/her lying down with legs slightly elevated. Cool his/her body by fanning and applying cool, wet towels. If conscious, allow the victim to drink approximately six ounces of water every 15 minutes. Follow up with a medical examination.

  • Heat Stroke – You or a bystander should immediately call an ambulance. Meanwhile, move the victim to a cooler area, remove any outer clothing, immerse him/her in cool water or apply cool, wet towels or cloths to the body. Do NOT give the victim liquids. If medical help is delayed, call the hospital for further instructions while waiting. Heatstroke is life-threatening, so it’s important to move quickly!


Safety Reminder

The risk of heat illness increases with age, poor diet, being overweight, insufficient liquid intake, poor physical condition, and/or when taking medication. Never take salt tablets without your doctor’s approval.

Be aware of expected weather conditions each day so that you can be prepared with appropriate clothing and beverages. If you are on a job and start to feel any adverse symptoms due to heat, inform your supervisor and take a break.
