Summer officially started on June 20 this year and that means the Southeast Texas heat is here to stay for a few months. Many Mason Construction, Ltd. employees work outside most days and have to be careful to maintain safe working conditions. Strenuous activities can easily lead to heat-related illness. Whether you are outside for work or personal time, monitor how your body is reacting to the heat.

According to the Occupational Safety & Health Administration, several factors put workers at greater risk:

  • Environment:
  • High temperature and humidity
  • Radiant heat sources
  • Contact with hot objects
  • Direct sun exposure (with no shade)
  • Limited air movement (no breeze, wind or ventilation)
Job-Specific:
  • Physical exertion
  • Use of bulky or non-breathable protective clothing and equipment

If you work outside (for example, at a construction site) or in a kitchen, laundry, or bakery you may be at increased risk for heat-related illness. So, take precautions. Here is how:

  • Drink small amounts of water frequently.
  • Wear light-colored, loose-fitting, breathable clothing—cotton is good.
  • Take frequent short breaks in cool shade.
  • Eat smaller meals before work activity.
  • Avoid caffeine and alcohol or large amounts of sugar.
  • Work in the shade.
  • Find out from your health care provider if your medications and heat do not mix.
  • Know that equipment such as respirators or work suits can increase heat stress.

There are three kinds of major heat-related disorders—heat cramps, heat exhaustion and heat stroke. You need to know how to recognize each one and what first aid treatment is necessary.

Heat Stroke is the most serious heat-related health problem. Heat stroke occurs when the body’s temperature regulating system fails and body temperature rises to critical levels (greater than 104°F). This medical emergency may result in death! The signs of heat stroke are confusion, loss of consciousness, and seizures. Workers experiencing heat stroke have a very high body temperature and may stop sweating. If a worker shows signs of possible heat stroke, get medical help immediately, and call 911. Until medical help arrives, move the worker to a shady, cool area and remove as much clothing as possible. Wet the worker with cool water and circulate the air to speed cooling. Place cold wet cloths, wet towels or ice all over the body or soak the worker’s clothing with cold water.

Heat Exhaustion is the next most serious heat-related health problem. The signs and symptoms of heat exhaustion are headache, nausea, dizziness, weakness, irritability, confusion, thirst, heavy sweating and a body temperature greater than 100.4°F. Workers with heat exhaustion should be removed from the hot area and given liquids to drink. Cool the worker with cold compresses to the head, neck, and face or have the worker wash his or her head, face and neck with cold water. Encourage frequent sips of cool water. Workers with signs or symptoms of heat exhaustion should be taken to a clinic or emergency room for medical evaluation and treatment. Make sure that someone stays with the worker until help arrives. If symptoms worsen, call 911 and get help immediately.

Heat Cramps are muscle pains usually caused by the loss of body salts and fluid during sweating. Workers with heat cramps should replace fluid loss by drinking water and/or carbohydrate-electrolyte replacement liquids (e.g., sports drinks) every 15 to 20 minutes.

Heat Rash is the most common problem in hot work environments. Heat rash is caused by sweating and looks like a red cluster of pimples or small blisters. Heat rash may appear on the neck, upper chest, groin, under the breasts and elbow creases. The best treatment for heat rash is to provide a cooler, less humid work environment. The rash area should be kept dry. Powder may be applied to increase comfort. Ointments and creams should not be used on a heat rash. Anything that makes the skin warm or moist may make the rash worse.

Be aware of these conditions both on the job and around your home during these hot summer months.

Make it a safe day!
