Bibliography

Provides recommendations for the design, installation, commissioning and maintenance of watermist systems.

This part of BS8489 gives recommendations for the design, installation, commissioning and maintenance of watermist systems. It gives performance criteria for fixed watermist systems for specific industrial and commercial hazards, for both life safety and property protection. The British Standard excludes: applications and occupancies which are not covered by relevant fire test protocols; watermist systems on ships, in aircraft, on vehicles and mobile fire appliances or for below ground systems in the mining industry; the use of watermist for explosion protection. NOTE BS8458 covers watermist systems in residential and domestic premises.
