Intrinsically safe mobile phones must meet special battery design criteria in order to achieve UL, ATEX directive, or IECEx certification for use in explosive atmospheres. Only properly designed battery-operated, self-contained devices can be intrinsically safe by themselves. Other field devices and wiring are intrinsically safe only when ...
Unlike ATEX which uses numbers to define the safety "Category" of equipment (namely 1, 2, and 3), the IEC continued to utilise the method used for defining the safe levels of intrinsic safety namely "a" for zone 0, "b" for zone 1 and "c" for zone 2 and apply this Equipment Level of Protection to all equipment for use in hazardous areas since ...
(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 ...
The controller requires only one communication point to communicate with up to 32 nodes, this is a significant improvement over the standard 4–20 mA communication method, which requires a separate connection point for each communication device on the controller system. The Foundation Fieldbus H1 has support for Intrinsically Safe Wiring ...
An electrical code is a term for a set of regulations for the design and installation of electrical wiring in a building. The intention of such regulations is to provide standards to ensure electrical wiring systems are safe for people and property, protecting them from electrical shock and fire hazards. They are usually based on a model code ...
Alcohol is used as a social lubricant, maybe more so as holiday festivities approach. But drinking carries health and other risks. Here are five tips to make it safer.
Plan Safe Transportation. Transportation plays a big role in ensuring your safety and comfort while traveling to gatherings. Whether you’re driving yourself, being picked up, or using a service ...
They continued to pressure the victim for more money, including wiring a third party $200,000 (£157,730) to cover "building supplies". In total, the McDonaghs stole almost half a million dollars ...
