We have a query regarding permitted NOISE LEVEL of a Fire Pump installed in a Gas Station.
NFPA 20 does not indicate any such requirement.
Environmental Agencies would like to enforce a noise level 75 db as applicable to Diesel Gensets. There it is done by by giving Soundproof Enclosure
Fire Pump set Manufacturer feels that there would be a problem of heat dissipation in case of air cooled / radiator cooled engine. They also feel there is an issue of approach to the Engine in Emergency.
