(CED22) Reprography Unit, SIS,New Delhi, India Fire Fighting Sectional Committee, CEO 22 FOREWORD This Indian Standard was adopted by the Bureau of Indian Standards, after the draft finalized by the Fire Fighting Sectional Committee had been approved by the Civil Engineering Division Council. Portable fire extinguisher, mechanical foam type. is one of the first-aid fire fighting appliance. In these extinguishers, foam is produced by ~pelling foam solution by stored air/gas and mechanical aeration at the foam making nozzle. This type of extinguisher is suitable for fighting fire in water non-miscible liquid, that is non-polar flammable liquids, that is Class A and B fires such as hydrocarbon fuels. For the purpose of deciding whether a particular requirement of this standard is complied with the final value, observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with IS 2 : f960 'Rules for rounding off numerical values (revised)'. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard. IS 15397: 2003 Indian Standard PORTABLE FIRE EXTINGUISHER MECHANICAL FOAM TYPE (STORED PRESSURE) - SPECIFICATION t SCOPE 3 PRINCIPLE AND DESIGN This standard lays down the requirements regarding 3.1 The method of expUlsion of mechanical foam is by principle, capacity, material, shape, design, air pressure stored in the container. The method of construction. anti-corrosive treatment an" tests of operation shall be upright by pressing a trigger tYlPe portable mechanical foam type (stored pressure) fire squeeze grip mechanism. ex ti ngu ishers. 3.2 During the operatiqn, should be able to strike tine side of the burning surface and engulf fire. 2 REFERENCES ..
