In electrical and safety engineering, hazardous locations (HazLoc, pronounced haz·lōk) are places where fire or explosion hazards may exist. Sources of such hazards include gases, vapors, dust, fibers, and flyings, which are combustible or flammable. Electrical equipment installed in such locations can provide an ignition source, due to ...
An operating temperature is the allowable temperature range of the local ambient environment at which an electrical or mechanical device operates. The device will operate effectively within a specified temperature range which varies based on the device function and application context, and ranges from the minimum operating temperature to the maximum operating temperature (or peak operating ...
Modern research shows that average internal temperature for men and women is 36.4 °C (97.5 °F). and that an individual's temperature fluctuates over time with a range of 36.5–37.5 °C (97.7–99.5 °F) being considered normal. Disease and preventive healthcare
The optimum temperature for thermal comfort of the skin surface is between 28 and 30 °C (82 and 86 °F), i.e., a neutral temperature. Thermophysiology reacts whenever the temperature falls below or exceeds the neutral point on either side; it is discomforting below 28 and above 30 degrees.
