More extinguishers

Soda Acid extinguishers are covered below. But while thinking about them I decided to post a few pictures of other styles of extinguishers. The history of fire exinguishers is varied. As you can tell by the photos here there are many styles and many methods of operation. There are links on the right for an extinguisher museum and I will be adding more links, photos, and information on this subject later on. enjoy the pictures.

Standard Water Extinguisher

This is a Pyrene Fire extinguisher showing in closed and open positions. This was manufactured in NYC. They are run by Kiddie Corp. which falls under Angus Fire. This particular extinguisher was manufactured in the early 1900s. The chemical used to put out fires was Benzo(def)phenanthrene and -pyrene, known in this use as Pyrene. The chemical itself is a polycyclic aromatic hydrocarbon (PAH) which is derived from coal tar. It is a neurotoxin, skin and sense toxin as well as having carcenogenic properties. The extinguisher is made of brass and is about a foot long and 4 inches in diamter. I am not sure exactly the nature of the manufacture of the chemicals or what relation the current owners had to the original production of these extinguishers. All of the chemical information I have posted is gleaned from another website.

This little extinguisher is a Presto "C B" extinguisher. It uses Chlorobromomethane to extinguish fires. It uses a small twisting knob to discharge the chemical to smother the fire. Merolite Industries from NYC made this. The extinguisher is made of brass and is around 5 inches long with a diameter of about 1 1/4 inches.

This is a Liberty Fire Extinguisher. It was made in Wawanesa, Manitoba, Canada for the Wawanesa Mutual Insurance Company. It lists that is contains a dry chemical in it, but I cannot find out what chemical it had in it. The extinguisher is about 1 1/2 feet long and around 2 inches in diameter, and has a pull tab at one end, which I assume is to activate the discharge.
