Regardless of whether you are working indoors or outdoors, working in hot and/or humid environments is not only uncomfortable but can lead to heat-related illnesses and can ultimately be fatal.
Causes and symptoms of heat stress
Heat stress occurs when an individual’s body temperature dangerously overheats due to prolonged exposure to hot or humid weather and the body’s inability to regulate its temperature generally through sweating.
Although heat stress is more prominent when working in outdoor environments such as mining, agriculture, refineries, and construction, it can often affect workers in indoor environments such as warehouses, boiler rooms and manufacturing plants too. Poorly ventilated areas, non-protective clothing, and hot areas (e.g., furnaces) can be common factors that result in heat stress.
The symptoms and signs of heat stress include:
Heat exhaustion – including dizziness, weakness, fatigue, vomiting, palpitations, and nausea
Dark coloured urine
Profuse sweating or no sweating
Not everyone reacts to heat the same way, and this can be influenced by factors including general health, body weight, medical conditions, and age just to name a few.
Monitor heat stress to protect worker safety
Environmental heat stress is measured in terms of Thermal Work Limit (TWL) and Wet Bulb Globe Temperature (WBGT) which takes into consideration radiant heat sources. TWL predicts the maximum level of work that can be carried out for the environmental conditions present at the worksite whilst WBGT is a measure of heat stress which takes into consideration radiant heat sources. Some solutions Air-Met Scientific provides for heat stress monitoring include:
Heat Stress Monitors – Discover the range of portable heat stress monitors supplied by trusted companies to provide a quick and accurate evaluation of heat stress environments. Heat stress monitors such as the QUESTemp QT-36 Portable Heat Stress Monitors are used to conduct a risk analysis of a job function or activity and assists in occupational heat stress management. It provides real-time readings for wet/dry bulb, WBGT indoor/outdoor and relative humidity.
Heat Stress Software – Heat stress software is essential for logging parameters, export and analyse data to gain crucial insights on environmental conditions.
Hydration Solutions - It is important for workers who are exposed to hot environments to keep hydrated while performing tasks to regulate body temperature and avoid heat stress. The Aqualyte Hydration Solution is a low sugar hypotonic fluid that prevents the effects of dehydration on health and performance.
Protect your workers from exposure to heat stress and stay compliant with Air-Met’s range of heat stress monitoring equipment and scientifically formulated hydration solutions.
