Carbon Dioxide Extinguishers (100 X2)

Carbon dioxide extinguishers are portable appliances designed and tested for operation over a temperature range of -40°C to +49°C. The fire extinguishing classifications of these extinguishers are developed at normal ambient temperature (approximately 21°C) and may be reduced at lower temperatures. Carbon dioxide is a nonconductor and its properties are such that when air is displaced by it, or mixed with it in suitable proportions, it is effective on Class B and C fires. In using extinguishers of this type, especially in unventilated places such as small rooms, closets, or confined spaces, operators and others should take precautions to avoid the effects which may be caused by breathing the vapours or gases liberated or produced. Extinguishers utilize CO2 stored in CTD- or DOT-3A or -3AA shipping containers which are equipped with special cutter or seated type valves, permitting release of CO2 gas through hand hose and nozzle (or tanks constructed in compliance with ASME Unfired Pressure Vessel Code Requirements). CTC or DOT shipping containers (cylinders) for carbon dioxide are required to be designed for 12,400 KPs or higher pressure and to be so marked. The small sizes are provided with a handle or strap for portability and a wall hook for mounting, whereas the large sizes are mounted on two-wheel tracks. Cylinders in service should be weighed semi-annually to detect loss of liquid by leakage, tampering or use. These appliances do not need to be protected against freezing. The extinguishers are capable of complete uninterrupted discharge at temperatures down to -40°C. If the discharge of the extinguisher is interrupted during an attach of a fire by closing the valve one or more times when the temperature of the extinguisher contents is below -18°C, blockage of the discharge may occur thereby rendering the extinguisher useless for any further use on the fire being attacked. This condition corrects itself without any damage to the extinguisher after a period of time, dependent upon the ambient temperature. Therefore, use of carbon dioxide extinguishers at temperatures lower than minus 18°C should not contemplate intermittent discharge. Marine Use - All ULC listed CO2 extinguishers have been approved for use within the jurisdiction of Canadian marine authorities where the extinguisher is of an appropriate size and classification. Compliance with the requirements of other marine jurisdictions will be indicated on the extinguisher label. Listing Service - These extinguishers are listed under the Label Service of Underwriter's Laboratories of Canada. Under this service, periodic examinations and tests are conducted on samples selected at random from current production and stock. Each listed extinguisher bears a label which reads: Underwriter's Laboratories of Canada LISTED Carbon Dioxide Fire Extinguisher – Classification . . . The ULC label or listed marking on a product is the only evidence provided by Underwriters' Laboratories of Canada to identify products which have been produced under the Listing and Follow-Up Service.
