FAQs:
1.What does "explosion-proof" mean? What is the difference between explosion-proof and intrinsically safe?
Explosion-proof equipment is designed so that should an explosion occur, then it will be contained with an adequate enclosure.
Intrinsically safe equipment is designed to limit the energy of sparks and surface temperature in order to inhibit an explosion from occurring.
Our hazardous area scales are intrinsically safe.
2.What is a Class 1 Division 1 hazardous area?
Class I Division 1 hazardous areas are locations that are defined by the National Electrical Code (NEC)
Handbook with articles 500, 501, 502, 503, 505, and 506.
Class I locations are those in which flammable gases or vapors are present in the air in quantities sufficient to produce explosive or ignitable mixtures (NEC 501).
Division 1 is a subset of Class I and is classified as an area where the explosive or flammable gases, vapors or liquids mentioned above can exist under normal, everyday operating conditions.
3.What is a Zone 2 hazardous area?
Zones are classified by the National Electric Code (NEC) and described in article 505.
One characteristic of Zone 2 areas is when ignitable concentrations of flammable gases or vapors are not normally present but could be present in certain cases that are clarified in the NEC standards.
Zones are also classified by ATEX 1999/92/EC Directive based on the frequency and duration of the occurrence of the explosive atmosphere.
Zone 2, according to ATEX 1992/92/EC Directive, is when an explosive atmosphere is likely to occur infrequently or for short periods of time.
4.What is explosion-proof wiring?
For explosion-proof wiring, which is required in Div 1, conduits and gaskets are required.
They are used to isolate the circuit from hazardous gases.
In sequences, a gasket is attached to the conduit as a fixture into which you can pour sealant.
This setup prevents the gases from flowing into the cable conduit and entering uncontrolled areas.
