DRY CHEMICAL FIRE SUPPRESSION SYSTEM
Dry Chemical Fire Suppression Systems consist of dry chemical compounds that suppress fire effectively because they are easy to install in any industrial setting. The Dry Chemical Fire Suppression Systems provide excellent fire coverage. The Dry Chemical agents come in ABC or BC. Cylinder should be recharged after every operation. These fire suppression systems are affordable and great to use when a water supply is not available to help extinguish fires.
Dry Chemical Systems a comply with NFPA 17 & NFPA 33, It is also suitable to comply with UL 1254
Different types of StatCon dry chemical agents are necessary to extinguish different types of fires. The different type fire classifications listed on the StatCon data sheets are based on NFPA Standards.
Classifications are as follows:• Class A - Fires in ordinary combustible materials such as wood, cloth, paper, rubber and many plastics.
• Class B - Fires in flammable liquids, oils, greases, tars, oil based paints, lacquers, etc. and flammable gases.
• Class C - Fires involving “live” electrical equipment where the use of a non-conducting fire agent is required.
• Class D - Fires involving combustible metals and their alloys such as magnesium, sodium, potassium, lithium, titanium, etc
In order of performance, fire tests on flammable liquids have shown potassium bicarbonate based dry chemical to be more effective than sodium bicarbonate based dry chemical.
Similarly, the monoammonium phosphate based dry chemical has been found equal to or better than the sodium bicarbonate based chemical.
“Multi-Purpose” (ABC) monoammonium phosphate based dry chemical agent is yellow in color. This agent is suitable for use on Class A, B or C type fires and of particular value on combination fires.
“Regular or Standard” (BC) dry chemical refers to an agent that is suitable for use on either Class B or C type fires. These agents are sodium bicarbonate based and blue in color.
Purple K (PK) dry chemical agent is based on potassium bicarbonate. Because of its fast extinguishing capability on flammable liquid fires, it is typically used in high hazard risk areas such as refineries, chemical plants or airports. The color of PK agent is purple.
