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 ...
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 ...
Inherent safety has been recognised as a desirable principle by a number of national authorities, including the US Nuclear Regulatory Commission [10] and the UK Health and Safety Executive (HSE). In assessing COMAH (Control of Major Accident Hazards Regulations) sites the HSE states “Major accident hazards should be avoided or reduced at ...
For this reason, optional intrinsic safety is fully integrated into the definitions of the Ethernet-APL communication standard. In the technical specification 2-WISE [3] the 2-wire intrinsically safe Ethernet is defined. The intrinsic safety barrier is an electronic circuit at each output or input of a switch or instrument. It prevents ...
DSEAR, the Dangerous Substances and Explosive Atmospheres Regulations 2002, is the United Kingdom's implementation of the European Union-wide ATEX directive.. The intention of the Regulations is to reduce the risk of a fatality or serious injury resulting from a "dangerous substance" igniting and potentially exploding.
The Process Automation division is a manufacturer of explosion protection products. It makes a range of intrinsic safety barriers, signal conditioners, remote I/O systems, HART interface solutions, surge protection, HMI systems, electrical explosion protection equipment, purge and pressurization systems, power supplies, and level measurement.
