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. ...

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 ...

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 ...

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 ...

Heat stress is a significant concern for athletes, workers, and military personnel who are exposed to extreme temperatures. As global temperatures rise and heatwaves become more frequent, understanding the risks associated with heat stress is more crucial than ever. The Wet Bulb Globe Temperature (WBGT) measurement has emerged as the most ...

Heat stress is no longer a seasonal inconvenience. For construction workers, it is a year-round occupational hazard with serious consequences. Recent studies, including groundbreaking work by the University of New Mexico, have shed new light on how heat affects the human body and why existing safety measures are insufficient.

In the military, environmental extremes are not just weather forecasts—they are operational variables. When it comes to heat, the U.S. Armed Forces rely on a standardized system of “Heat Flag Conditions” to evaluate heat stress risk and adjust training, physical activity, and work schedules accordingly.
These color-coded flag ...

Heat domes are increasingly dominating headlines—and for good reason. As prolonged heat waves sweep across the United States, these phenomena are pushing temperatures into record-breaking territory, threatening infrastructure, health, and regional stability. But what exactly is a heat dome, and why are they becoming such a persistent force in...
