Intrinsic safety (IS) is a protection technique for safe operation of electrical equipment in hazardous areas by limiting the energy, electrical and thermal, available for ignition. In signal and control circuits that can operate with low currents and voltages, the intrinsic safety approach simplifies circuits and reduces installation cost over ...
Equipment can be designed or modified for safe operation in hazardous locations. The two general approaches are: Intrinsic safety Intrinsic safety, also called non-incendive, limits the energy present in a system, such that it is insufficient to ignite a hazardous atmosphere under any conditions. This includes both low power levels, and low ...
(Kletz originally used the term intrinsically safe in 1978, but as this had already been used for the special case of electronic equipment in potentially flammable atmospheres, only the term inherent was adopted. Intrinsic safety may be considered a special subset of inherent safety). In 2010 the American Institute of Chemical Engineers ...
A more recent enhancement for intrinsically safe applications is the High Power Trunk (HPT) with field-based field barriers (FBs), which limits power at the spur, rather than the trunk. This method significantly changes the equation for end users of Fieldbus in hazardous settings.
Heat exchangers: In industries like HVAC and chemical processing, heat exchangers use thermal conductance to efficiently transfer heat between fluids. Aerospace: In spacecraft and aircraft, thermal resistance and conductance are critical for managing temperature variations in extreme environments. Designing spacecraft and aviation systems ...
Three dogs attacked their owner at a San Diego park Friday, killing the man and injuring another person, according to authorities and the Humane Society.
The Alzheimer's Association released a list of gift recommendations for individuals with the disease at every stage of dementia. Experts offer insights on how to navigate the holiday amid dementia.
