A device which is termed "intrinsically safe" has been designed to be incapable of producing heat or spark sufficient to ignite an explosive atmosphere, even if the device has experienced deterioration or has been damaged. There are several considerations in designing intrinsically safe electronics devices:
A crossing arm is a safety device intended to protect children from being struck while crossing in front of a school bus. Typically, school bus crossing arms are wire or plastic devices which extend from the front bumper on the right side of the bus when the door is open for loading/unloading and form a barrier.
(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 ...
Here are 5 cool gadgets designed to meet the needs of kids with disabilities. 1. Xbox Adaptive Controller . gamers with limited mobility can connect external devices such as switches, buttons ...
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 ...
The ATEX Directive has also adopted a functional safety standard, it is BS EN 50495:2010 "Safety Devices Required for the Safe Functioning of Equipment with Respect to Explosion Risks" covers safety related devices such as purge controllers and Ex e motor circuit breakers. It is applied by notified bodies under the ATEX Directive. The standard ...
The terms "active" and "passive" are simple but important terms in the world of automotive safety. "Active safety" is used to refer to technology assisting in the prevention of a crash and "passive safety" to components of the vehicle (primarily airbags, seatbelts and the physical structure of the vehicle) that help to protect occupants during a crash.
A child safety seat, sometimes called an infant safety seat, child restraint system, child seat, baby seat, car seat, or a booster seat, is a seat designed specifically to protect children from injury or death during vehicle collisions. Most commonly these seats are purchased and installed by car owners, but car manufacturers may integrate them ...
