Heat Stroke – Signs & Symptoms

Heat Stroke – Signs & Symptoms
 

AN IMPORTANT NOTICE FROM THE INJURED WORKERS’ COMMITTEE REGARDING HEAT STROKE & HEAT EXHAUSTION

Next week a major heat wave is expected to hit Ontario so it’s vital that all workers take precautions to protect themselves against heat stroke & heat exhaustion.

Most people feel comfortable when the air temperature is between 20°C and 27°C and the when relative humidity ranges from 35 to 60%. When air temperature or humidity is higher, people feel uncomfortable. Such situations do not cause harm as long as the body can adjust and cope with the additional heat. Very hot environments can overwhelm the body’s coping mechanisms leading to a variety of serious and possibly fatal conditions.

When the air temperature or humidity rises above the optimal ranges for comfort, problems can arise. The first effects are subjective in nature – they relate to how you feel. Exposure to more heat stress can cause physical problems such as heat cramps, heat exhaustion and heat stroke, all of which impair workers’ efficiency, and may cause adverse health effects.

The following are some of the symptoms of heat exhaustion and heat stroke. If you or a co-worker exhibit any of these symptoms seek medical attention immediately.

Symptoms of Heat Exhaustion

•             Heavy sweating
•             Cool moist skin
•             Strong thirst
•             Quick pulse
•             Rapid breathing
•             Feeling of fatigue and possible fainting

Symptoms of Heat Stroke

•             High body temperature (>40°C)
•             Very hot, red and dry skin
•             Tiredness / confusion
•             Very rapid pulse
•             May suffer convulsions

Tips For Working Safely in Hot or Warm Weather:

•             Stay hydrated
•             Drink plenty of water – frequently (equivalent of about one litre every hour)
•             Avoid consuming caffeine and alcohol, which can dehydrate you

In Solidarity,
