  1. How Dangerous Is Heat Stress in the Oil and Gas Industry?

    How Dangerous Is Heat Stress in the Oil and Gas Industry? Oil and gas extraction (OGE) involves work in some of the harshest environments on Earth. Workers are exposed to high temperatures, intense physical labor, protective gear that restricts cooling, and sometimes hazardous working conditions. Heat stress in this industry is not just uncomfortable; it can be life-threatening. It is dangerous. ... Read more...
  2. What is the Heat Stress Index and How Do I Measure or Use It?

    What is the Heat Stress Index and How Do I Measure or Use It? In hot conditions, it is not enough to track air temperature alone. Humidity, wind, sunlight, radiant heat, and physical activity all influence how the body regulates its temperature. That is where the concept of a Heat Stress Index comes in. The Heat Stress Index is a calculated value designed to provide a safer and more comprehensive ... Read more...
  3. What is the Threshold Limit Value (TLV) and How Can You Measure It?

    What is the Threshold Limit Value (TLV) and How Can You Measure It? In many workplaces, especially those involving chemicals, dust, fumes, or vapors, knowing the safe exposure limit isn't optional. The Threshold Limit Value, or TLV, is one of the most crucial tools in industrial hygiene for maintaining worker exposure below hazardous levels. It represents airborne concentrations of substances that nearly all ... Read more...
  4. What is Humidex and How Can You Measure It?

    What is Humidex and How Can You Measure It? Humidex is a weather metric used to describe how hot it feels when humidity is factored into the air temperature. It was developed in Canada during the 1960s and refined around 1979 by J. M. Masterton and F. A. Richardson. The purpose is simple: when humid and hot conditions combine, our ability to cool down through sweating is reduced, making ... Read more...
