Fire Extinguishing Agent

Development of method for cost effective and quality upgradation of phosphate based dry fire extinguishing agent

Overview:

Dry Chemical fire extinguishers extinguish the fire primarily by interrupting the chemical reaction of the fire triangle. The multipurpose dry powder works by creating a barrier between the oxygen element and the fuel element on Class A, B & C fires. It is monoammonium phosphate based containing chemical additives, and produced by an exclusive chemical process. The resultant agent is free-flowing, water repellant, non-abrasive, and when used as a fire suppressing agent will produce no toxic effects. In this project, we will produce an advanced multipurpose fire extinguishing agent by formulating mono-ammonium phosphate, ammonium sulphate, magnesium aluminum silicate, potassium aluminum silicate, calcium carbonate etc in different proportion. This project will enhance the research scopes and facilities of chemical research division.

Objective:         

  • To develop a process for the production of high efficiency and cost effective advanced and modified form of phosphate based fire extinguishing agent from locally available chemicals for multipurpose fire extinguisher.
  • Successful completion and industrialization of this project generate employment for unemployed men & women.

Progress:

  • Raw material has been collected and purified them well.
  • Optimization of different parameters in target to modify or upgrade the said product Progress is 50%.
