What is meant by "Intrinsically Safe"?

Through the use of special components, materials, ratings and component layouts, all electric circuits and inter-connected cables are designed so that

a) no spark or
b) thermal effect is capable of causing ignition under fault conditions.

Intrinsically safe equipment can be isolated by Zener barriers from non-intrinsically-safe circuits for data transfer to the safe area

Basic principles of intrinsic safety:

• Voltage limitation
• Current limitation
• Limitation of storable energy

Advantages of intrinsically safe protection

• Equipment can be calibrated and maintained without removing power
• General purpose wiring methods can be used for connection to power
• No safety permits are required since the area does not need to be “shut down" for servicing

Classification of Hazardous Locations in the United States

Class

• Class I - locations in which hazardous concentrations of flammable gases or vapors exist
• Class II - locations which are hazardous due to the presence of combustible or electrically conductive dust of fibers

Division

• Division 1 - present continuously, intermittently or periodically during normal operating conditions
• Division 2 - not present under normal operating conditions, but as a result of equipment failure, breakdown of containers or abnormal operation of ventilating equipment

Groups

• Group A - atmospheres containing acetylene
• Group B - atmospheres containing hydrogen, gases or vapors of equivalent hazard such as natural gas
• Group C - atmospheres containing ethyl ether vapors, ethylene or cyclopropane
• Group D - atmospheres containing gasoline,hexane, naptha, benzine, butane, propane, alcohol, acetone, benzol, lacquer solvent vapors or other natural gases
