CO2 Hose Reel

CARBON DIOXIDE Carbon dioxide (CO2) is an effective agent for extinguishing fires by smothering them; that is, CO2 reduces the amount of oxygen available for combustion. This smothering action is temporary and you must remember that the fire can quickly rekindle if oxygen is again admitted to the hot embers. CO2 is a dry, noncorrosive gas that is inert when in contact with most substances. It is heavier than air and remains close to the surface. CO2 does not damage machinery or other equipment. Since it is a nonconductor of electricity, CO2can safely be used to fight fires that might present electric shock hazards. However, the frost that collects on the horn of a CO2 extinguisher does conduct electricity. Therefore, you should be careful and never allowthe horn to come into contact with electrical components. Aboard ship a 50-pound CO2 hose and reel installations, Although CO2 is nonpoisonous, it is dangerous because it does not provide a suitable atmosphere for breathing. Asphyxiation can result from breathing CO2; therefore, an oxygen breathing apparatus (OBA) must be worn when CO2 is used below decks or in confined spaces.

Hose reel system consist of 2 50 lb CO2 bottles (reduced 10 percent for high temp areas) a 50 foot hose, a control vlave and a horn.
