Hazardous & Explosion Proof Video Surveillance

Author: Brian Rhodes, Published on Mar 24, 2016

Placing surveillance cameras in hazardous, highly flammable environments call for equipment certified not to spark or ignite. These requirements are far more stringent than typical surveillance gear. Because of these elevated requirements, cost is much more expensive. Inside, we discuss:

  • Where is Explosion Proof Equipment used?
  • What are the ratings? Including NFPA 70, EX, Division 1, Division 2, and ATEX directives 95/137
  • What do the ratings mean?
  • Hazardous Rated Camera Options including Axis, Bosch, Moog, Pelco, and IVCCO.
  • Typical Product Cost
  • Alternatives to using rated equipment?

One of the best articles I have seen on the (often confusing) subject! Thanks, Brian!

In terms of rating, I would like to add the following NorthAmerican standard NEC505 that further breaks down the classified areas (vs the NEC500).

Here is the link to the UL document and basically this standard is more in line with IECEX (International Electrotechnical Commission Systems) and ATEX.

This is a comparison between the standards NEC 500 and ATEX, IECEX, NEC505:

Zones

Hazardous explosive atmosphere

Continuously, frequently or long term

Occasionally

Rarely and briefly

GAS

ATEX/IECEX/NEC505

Zone 0

Zone 1

Zone 2

NEC500

Division 1

Division 2

DUST

ATEX/IECEX/NEC505

Zone 20

Zone 21

Zone 22

NEC500

Division 1

Division 2

Groups

ATEX/IECEX/NEC505

NEC500

Group I

Underground parts of mines likely to be endangered by firedamp

-

Methane

Group II

Subgroups

Explosive gas atmospheres:

Typical gas

Class I

IIA

Propane

Class I Group D

IIB

Class I Group C

Class I Group B

Class I Group A

Group III

Subgroups

Explosive gas atmospheres:

Typical Dust

IIIA

Combustible lint

Fibers and lint

Class III

IIIB

Non conductive dust

Non-carbonaceous dust

Class II Group G

IIIC

Conductive dust

Carbonaceous dust

Class II Group F

Metal dust

Class II Group E

For other countries there are other specific certifications:

EAC EX certificate is a document that confirms the conformity of a product to the EurAsEC Customs Union standards. The certificate is necessary for importing and selling products in the EAC Custom Union: Russia, Belarus and Kazakhstan.The basic requirements for testing, in general, comply with existing standards IECEx with some national deviations.

Chinese Ex certification it’s is a voluntary certification of the China explosion proof products. The basic requirements for testing, in general, comply with existing standards IECEx with some national deviations.

KCs is the certification of the Korean explosion proof products.The basic requirements for testing, in general, comply with existing standards IECEx with some national deviations.

In terms of equipment, there are several providers of ex-proof product.

For ex. Videotec offers a broad range of solutions: full HD IP, thermal and analogue fixed exproof cameras, full HD and SD IP and analogue PTZ cameras, dual core (thermal+visible) PTZ cameras, housings for third parties cameras and various accessories.

This is very helpful. Thank you!

Interesting that terms like dust-proof, water-proof and bullet-proof are specifying a certain degree of ingress resistance but explosion-proof is actually an egress resistance.

What's the term for an enclosure that can resist external explosions?

Thanks for the link! I read quite a few after that as well.

A couple of things if you would like to confirm what I think learned:

Intrinsically safe I.S. and Explosion-proof E.P. equipment are different ways of achieving the same goal, not causing an explosion in the hazardous area.

But, implementation wise they are opposites:

I.S. equipment designed to prevent any sparking/exploding within itself.

E.P. equipment is designed contain any sparking/explosion within itself.

Therefore I.S. equipment need not be E.P. and vice versa.

Devices with higher power draw tend towards E.P and lower draw tend towards I.S.

Also, explosion-proof != blast-proof, blast proof protects the inside from explosions on the outside and explosion-proof does the reverse. Though in practice, if one does either, likely does the other to a large degree.

Did I get it right?

This could be a good step off for a discussion of what the terms 'intrinsically safe' and 'explosion proof' means. Some use this interchangeably but there is a difference.

If only you had posted this two months ago! I spent weeks muddling through this.

Very appropriate article for this very important and critical subject! I have worked in the refining and chemical industry for a long time and managing and designing video systems to meet stringent Class 1 Division 1 or Division 2 area requirements can be difficult and expensive.

I have been waiting for an article like this from IPVM for a long time. Good job!
