fire extinguishers and Columbus fire suppression systems. Monoammonium phosphate is the multipurpose fire-extinguishing agent used in most fire extinguishers around the world. It is a yellow powder with a faint ammonia odor. Like all other dry chemical agents, it is nontoxic, but caution should be exercised around people with existing respiratory conditions.
Potassium bicarbonate is one of the most effective dry chemical extinguishing agents ever developed. However, it is also one of the most expensive and its use is reserved for aircraft firefighting and other expensive equipment protection. Sodium bicarbonate has become a more specialized agent used largely in fire suppression systems for commercial cooking operations. It is generally accepted that dry chemical agents extinguish fire by interrupting the chemical chain reaction, although there is also some smothering and cooling that contributes in a small way.
Dry chemical fixed suppression systems are primarily used for flammable liquid and gas fires. There are two basic types of suppression systems, total flooding and hand hose/local application. Dry chemical agents are usually expelled from their container by gaseous nitrogen. Fixed suppression systems are automatic and operate when a sensing device in the protected area detects elevated heat and activates and shuts down process equipment as required by NFPA 17. columbus fire suppression systems also have manual actuation devices similar to manual fire alarm pull stations to instantly activate the system. When dry chemical systems are used to protect commercial cooking operations, they must also shut off the fuel supply when the system discharges. One of the drawbacks to using a dry chemical extinguishing system is the mess it creates in the protected area when it discharges. Cleanup and downtime for a business or operation following a discharge can be extended with dry chemical agents. It is important to consider a lot of things before buying the suppression system. Make sure to do a lot of research and gather as much as information about the suppression system before buying or installing. In fact only with proper information and research homeowners will be able to make the right decision.http://www.amazines.com

Borax and sodium bicarbonate agents were among the first dry chemical extinguishing agents developed. Sodium bicarbonate rose to the surface as the preferred agent based upon its effectiveness in extinguishing fires. Urea-potassium bicarbonate-based extinguishing agents were developed in the late 1960s. Monoammonium phosphate and potassium bicarbonate extinguishing agents became the next agents developed and remain in the forefront of today’s modern
