Medium Velocity Water Spray System is used for the following:

a) In fire risks involving lighter oils/ LPG
b) Protection of vessels, plant / structures exposed to heat from adjacent and surrounding fires
Fires involving liquids with flash points below *2 0C cannot always be extinguished by water spray. Medium Velocity Water Sprayers giving medium drop size can be successfully employed for flame control in many cases. It is important to use the correct water density rate and drop size, to avoid undue agitation of the burning liquid. Flame height can be controlled within tolerable limits, and personnel can enter the area to drain off the liquid and carry out any other measures necessary to bring the situation under control.

Gases liberated from these highly volatile liquids from explosive mixtures with air. They are mostly heavier than air, and dissipation may be very slow. Ignition can take place at considerable distances from a source of leakage, and extensive fires result. Medium Velocity Water Sprayers are positioned to cover valves and joints where leakage may occur, and enable the gas to be burnt safely until the leakage is sealed off.

Hazards of this kind are always present where Liquefied Petroleum Gases (commonly termed as LPG) are being stored, transported, or used in manufacturing processes.
