chemical plants, warehouses, etc. Production of this sensor is being carried out by Southern Electronics Pvt. Ltd., a Bangalore based private manufacturer. Fire extinguishing chemicals A vapour-based fire extinguisher, developed jointly by CFEES and Indian Institute of Chemical Technology, Hyderabad, uses hepta-fluropropane as a replacement to halon-1301, which has been banned by the Montreal Protocol. A monoammoniumphosphate (MAP)-based multi-purpose, dry chemical ABC powder for extinguishing fires has also been developed. This is environment-friendly as it does not release toxic gases or residue. Production of the same is being carried out by K.V. Fire Chemicals Pvt. Ltd., Mumbai, which plans to introduce it into the civilian market. Environment protection Technology for the treatment and stabilisation of Heavy metals (Pb, Cr, Hg, Cd, Zn etc.) from effluents being generated by Ordnance Factories and other manufacturing plants. The technology uses a cement/polymer-based solid matrix, and is being license-produced by Quality Water Management Systems Pvt. Ltd., Chennai. Technology for removal of nitro bodies (HMX, RDX) from HMX plant effluents (based on neutralisation and alkaline hydrolysis). CFEES has also built up expertise in the area of establishing ground water monitoring networks for any project site. CFEES has developed processes for producing Coal Pitch based Activated Carbon Spheroids for adsorption of harmful chemical vapours by the protective gears. This is used for protection against nuclear, biological and chemical warfare. The powder has good mechanical strength, low ash content and is eco friendly. A National Halon banking and management facility has been set up, where impure halon can be purified to acceptable levels and stored.
