Approved flashlight for gas work
« on: June 29, 2018, 07:27:50 PM »
Hi All,
In the B149.1-15, 4.12.2   "A light, including a flashlight, used in connection with a search for gas leakage shall be of the Class 1, Group 11A type."   

Now, first, I assume that by "11" that they mean "2", since apparently there is no Division 11 (eleven).  I am looking at the following website:
http://www.flashlightuniversity.com/flashlight-safety-ratings-and-approvals/

And, according to the above website, I presume that the TSSA really means Class 1, Div 2, Group D.

I haven't bought one yet and want to make sure I get the right one.

I remember always hearing class one, group D... I use the cheapest ones I can find since I lose flashlights like they're going out of style.

It's the CSA who published the B149.1-15 Code book.  You're right, Clause 4.12.2 should say "Group IIA", not "Group 11A"

The US may use a different system.  In Ontario Group IIA includes propane and natural gas.  See Ontario Electrical Safety Code Rule 18-050,

Quote
18-050 Electrical equipment (see Appendix B)
(1) Electrical equipment for use in hazardous locations shall be suitable for the specific explosive atmosphere that will be present.
(2) Equipment with a type of protection permitted in a Zone 0, Zone 1, or Zone 2 location shall be suitable for one of the following:
(a) Group IIC, consisting of atmospheres containing acetylene, carbon disulphide, or hydrogen, or other gases or vapours of equivalent hazard;
(b) Group IIB, consisting of atmospheres containing acrylonitrile, butadiene, diethyl ether, ethylene, ethylene oxide, hydrogen sulphide, propylene oxide, or unsymmetrical dimethyl hydrazine (UDMH), or other gases or vapours of equivalent hazard;
(c) Group IIA, consisting of atmospheres containing acetaldehyde, acetone, cyclopropane, alcohol, ammonia, benzine, benzol, butane, ethylene dichloride, gasoline, hexane, isoprene, lacquer solvent vapours, naphtha, natural gas, propane, propylene, styrene, vinyl acetate, vinyl chloride, xylenes, or other gases or vapours of equivalent hazard; or
(d) XXXXX, where XXXXX is a chemical formula or chemical name suitable for that specific gas or vapour.
(3) Equipment marked Group “IIC” shall be permitted to be used for applications where Group IIA or Group IIB equipment is required.
(4) Equipment marked Group “IIB” shall be permitted to be used for applications where Group IIA equipment is required.
(5) Equipment marked for a specific gas or vapour shall be permitted for applications where the specific gas or vapour may be encountered.
(6) Equipment with a type of protection permitted in a Zone 20, Zone 21, or Zone 22 location shall be suitable for one of the following:
(a) Group IIIC, combustible metal dusts;
(b) Group IIIB, combustible dust other than combustible metal dust; or
(c) Group IIIA, solid particles, including fibres, greater than 500 ?m in nominal size, that may be suspended in air and could settle out of the atmosphere under their own weight.

Yeah that's all I have right now is LED.  Himark said it was ok for in class.  I use a holder that fits on the belt, I haven't lost my LED one yet.  The guys in my co-op are always asking me to borrow it.  I think I'll contact TSSA and tell them about the mistake.  They have forms you can fill out for corrections/suggestions.

Thanks all.  Once again this forum has been very useful.  We should all have a BBQ sometime.
