module 8 Flashcards
percentage of cause of fire ?
accidental - 57%
Arson - 43%
what are the legal requirements under the RRO regarding environmental protection?
preauction to minimise environmental damage
protection of water courses
storage area for run off FF water
- bunded area/ interceptors
- -ground level access
- bunded tanks
what is fire safety management ?
the must be arrangements for:
- planning
- organisation
- monitoring and reviewing the general precaution’s
examples of RIDDOR
explosion , collapse or busting of closed vessel or associated pipework
electrical short or overloading leading to suspected operations over 24 hours.
sudden uncontrolled release in a building of 100 KG or more of a flammable liquid.
7 day injuries for RIDDOR ?
result of a fire
more than 7 days absence from work ( excluding event day)
includes all days, not just working days
report must be made within 15 days of event
a fire emergency pan must ensure ?
person know what actions to be taken in the event of a fire
the premise can be evacuated safely .
persona can assemble in a place of total safety
all person are accountable for at the assembly point
appointed persons ensure building is evacuated
A fire emergency plan should ensure?
plans are made for persons unable to evacuate the premise
persons are restricted from re-entering the premise, until safe to do so
the foregoing will take into account the building layout , ease of evac, the number for evac, including victors etc.
what are the fire emergency plan contents ?
warnings within the workplace
action of persons on discovering a fire or alarm being raised
actions to mobilise emg services
evac procedure
assembly point and routine
action to meet / advise the emg services
measure to evac person unable to self evac
measures to give the incident all clear.
fire drill requirements?
should be atlest once a year
the drill is to test staff know the evac procedure
should be held under strict supervision
prior notice should be given to those involved
varied by use of exit available
the assembly point and roll call should also be tested
should be followed by a debrief
Objective of Evacuation Strategy
The primary objective of an evacuation strategy is to ensure that in the event of a fire, the occupants of a building can reach a place of ultimate safety outside the building
•The evacuation strategy should not rely on external assistance (e.g. from the fire and rescue service) and should be chosen to take into account:
1.The risk profile of the building; and
2.The required evacuation time.
Categories of Evacuation Procedure
There are two basic categories of evacuation procedure:
•Total evacuation of the occupants to a place of ultimate safety, by either simultaneous or phased procedures;
•Progressive evacuation of the occupants, initially to a place of relative safety within the building where they can remain or, if necessary, complete the evacuation to ultimate safety as part of a managed system
Total Evacuation – Simultaneous Evacuation
Adopted where it’s unreasonable to expect the occupants to remain in the premises.
There are two categories of simultaneous evacuation:
•Single-staged evacuation
In a single-staged evacuation, the activation of a call point or detector gives an instantaneous warning from all fire alarm sounders for an immediate evacuation.
Two-staged evacuation
A typical sequence of events for two-staged evacuation is as follows:
1)Initially a coded staff alert is given
2)There is then an investigation period (or grace period)
3)The evacuation signal is broadcast if:
•a fire is confirmed; or
•an agreed investigation period lapses without the alarm being cancelled; or
•a second detector is activated, ‘break glass’ operated or sprinkler flow switch operated during the investigation period.
Total Evacuation – Phased Evacuation?
Phased evacuation is a common approach adopted in high-rise premises or in certain atrium buildings
•The first to be evacuated are all those on the storey affected by the fire, and those on other floors with mobility impairment (unless their PEEP has determined otherwise)
•The remaining floors are then evacuated, usually two floors at a time, at phased intervals
•
No set order for how these floors will evacuate, e.g. could be the two floors above the fire & progress up the building or start with the two uppermost floors and work down
•This is building specific and will form part of the building’s evacuation strategy.
Phased evac typical example
Fire floor evacuates
•Mobility impaired on all other floors evacuate – unless their PEEP determines otherwise
•Two floors above go into alert.
The following conditions should be met in any building or part of a building that is designed on the basis of phased evacuation.
- The stairways should have a protected lobby or protected corridor approach (except the top storey) or have a pressurised stairwell.
- Every floor should be a compartment floor.
- If the building has a storey with a floor over 30m above ground level, the building should be protected throughout by an automatic sprinkler system conforming to BS EN 12845.
The building should be fitted with a fire warning system, conforming to at least the L3 standard given in BS 5839-1:2002 & A2:2008
- An emergency voice communication system should be provided in accordance with BS 5839-9, with outstations at each floor level which communicate with a master station located in the building control room (where one exists) or some other suitable control point at fire and rescue service access level
- Lifts should be approached through a protected lobby.
