  12. 12. Basics of Intrinsic Safety INTRINSIC SAFETY Intrinsic Safety is one of several design techniques that is used to protect electrical equipment and wiring in a hazardous (classified) location. Fuel, oxygen, and a source of ignition in the necessary IGN proportions must be present for combustion to occur. ITI EL O FU NS OU Intrinsic Safety is the technique that RC reduces / removes the ignition source E OXYGEN Ignition Triangle Lunch and Learn 2008 12
  13. 13. Basics of Intrinsic Safety Intrinsic safety is a design technique applied to protect electrical equipment and wiring in hazardous locations. A System Concept Not just components, how does each part fit together to create a safe system cables consumer source The technique is based on limiting energy, electrical and thermal, to levels below that which is required to ignite a specific hazardous atmospheric mix. Simplest and most effective protection method for instrumentation Lunch and Learn 2008 13
  14. 14. Basics of Intrinsic Safety Advantages of Intrinsic Safety No special constructions (e.g. flameproof enclosure) for field devices. No conduit seals Cables are also included in the explosion protection, Suitable for Division 1 applications (also Class 1 Zone 0). Calibration, function test, exchange of devices etc. possible while energized, no interruption of operation. I.S. is the only protection technique which allows “live maintenance”. Lunch and Learn 2008 14
  15. 15. Basics of Intrinsic Safety Disadvantages of Intrinsic Safety Intrinsic safety places a high demand on the designers and installers due to the system concept. Not only are there design regulations for the individual devices but also:  the correct interconnection between all devices in the I.S. circuit  the correct installation with an emphasis on protection of the I.S. circuit from external energy and grounding requirements.  only for circuits with a relatively low power consumption (perfect for process automation) Lunch and Learn 2008 15
  16. 16. Basics of Intrinsic Safety Origin of Intrinsic Safety Origin: Explosion in a mine in Wales in 1913 which killed over 400 men Cause: The energy stored in the circuit in a hazardous location.
