FIRE HYDRALICS AND FIRE LOSS CONTROL

Fire Hydraulics and Fire Loss Control

Lesson 5

Control of Air Flow

ventilation control: 

flow of air will help the fire. to achive the aim of reducing the flow of air to a room and limit the spread of smoke, in the shortest possible time, the standard procedure is

crash stopping all ventilation fans (blowers / exhausts) as soon as the alarm is raised this action significantly contributes towards reducing the supply of air to the fire prevents the smoke from spreading

a)      restoring power to all ventilation systems so that they may be restarted

b)      supply ventilation is essential system and rooms not affected by fire

      c) contain the smoke within the desireed boundary and prevent the supply of air to the fire

      d) remove smoke from arteas adjacent top the fire and remove all smoke and furnes after       extinction

crash stopping ventilation:

a)      shut down main power supply immediatedly to whole areas of industry. switch on necessary lioghting power supply at the switch board after five seconds.

b)      trip the local starters of general ventilations fans which are not controlled from ventrilation breakers

c)       if industry is provided  with centralized air conditioned air supply it has be controlled at ventilstion trunking

d)      electrical sipplies must be available to all ventilation systems as soon as possible after crash stopping so that systems essential and which do not intrefere

e)      care must be taken that smoke is not pickes up by suctions of hp air compressor and by essentials systems to living spaces

f)       boundaries must be established to ensure that smoke is contained

g)      when using exhaust fans a route top atmosphere must be opened up to allow make up air tyo enter inside

machinery space ventilation:

a)      close the ventilation supply flaps to the machinery space affected

b)      stand by top close ventilation exhaust flaps, but do not close untol ordered, so that the exhaust system can be continue to be used for the first aid fire fighting

c)       restore essentials ventilation:

d)      boundary cooling:

e)      smoke clearance:

f)       area classification:

g)      high fire risk:

h)      explosive risk:

i)        electronic and high value:

j)        accomadation spaces:
