When trying to make my car legal for CARS regs. I had to get rid of my 2
Halon fire extinguishers because Halon is banned in Canada.

When reading the rules :

2 - 5 lb.

or

1 - 10 lb.

When shoping the local fire stores I was surprised to discover that this size is only a 2.5 lb. :

And this is the 5 lb. :

I've noticed a lot of cars running the 2 - 2.5 lb. fire extinguishers. Is there a rule that allows them because of a grand fathering clause ?


edit - keep in mind the images are of different sizes, look at the proportion of the valve in relation to the tank.

You should download the CARS rules, they are available here: http://209.250.151.132/CARSRally/Default.aspx?tabid=92

It says a minimum of 1 10BC, or 2 5BC extinguishers. The unit is BC, not lbs. A 10BC fire extinguisher is the same as a 5lb unit.

Also, it says in the rules that "Halon or other similar gases are strongly recommended"
I'm sure that's what everyone would use if it wasn't 4x the cost.

Everyone would use Halon if you could get it. It is an illegal substance. No one will sell it to you and no one will recharge or recertify so a halon extinguisher in Canada is useless.

Actually, the unit of measurement varies whether you're talking about a Class A or B extinguisher. The "C" designation doesn't have any units associated with it - it only indicates that the extinguishing agent is appropriate for an electrical fire.

For Class A extinguishers, the number is the extinguishing power measured in an equivalent amount (in either lbs or gal - I can't remember which) of water.

For Class B extinguishers, the number is the approximate square footage of flammable liquid fire that a non-expert should be expected to put out.

So, a 10BC extinguisher can put out 10 square feet of burning liquid and is safe to use on electrical fires. If you had a 1A-10BC extinguisher, it would be appropriate for other, non-automobile type fires (e.g. grass, wood, etc.).

Yeah that was the problem with my Halon's, they were last serviced in 2002 and too old.

When contacting a fire supply store and I asked them if they could dis-charge the halon and then re-fill them with something else. They told me that is illegal in Canada to dis-charge Halon even in a controled environment with adequate filters.

Thank you for the clarification between lb. and BC !

I guess I have twice the fire protection in my car, whcih if needed I'm sure would be welcome.

What replaced Halon ?

Or is there a replacement ?

I am not sure abouut portable uses, but for fixed applications there are some products. At work we replaced a Halon system (IT Computer room) with FM-200 (hexaflouropropane (sp?)). There is also one called Intergen. The problem with both of these and especially with Intergen, is that you require more of the material than Halon.
