Who is in charge of a incident
Incident commander, wears white and yellow vest
Incident commander role
- in charge
- adapts plans based on risk assessment
- set tactical priorities
- has authority to deploy BA
Who controls a sector of a incident and what is there role
Sector commander
- takes control of a specified area
- reports to incident commander
- co-ordinates BA briefs and search patterns
- red yellow tabard
Who controls BA before going in
ECO ENTRY CONTROL OPERATIVE
- monitors BA
- incident commander and sector commander are above ECO
- complete records
- buddy checks
- black and yellow chequered tabard
How many people in a BA team
- 2 minimum
- BA team leader and BA no2
What do you have when BA teams are in a building to be safe
Emergency team
- only if enough firefighters
- will stand by ECP for duration of BA is in use
- always considered when BA is in use
Where should you site the ECO board and who runs it
Away from Incident but in view of the incident not close to the applicable due to noise. Not in area of smoke from building or in way and working teams at incident. ECO runs the EVO board.
What is the critea for stage 1
- Minimum standard control measure for an incident.
- incident requires no more than one BA entry control point
- requires no more than six BA wearers to be deployed to the risk area at one time.
- BA guidelines are not required
What is initial deployment
- resources available are limited
- a crew member, May be the OIC, will be made responsible for monitoring the BA team
- opportunity to preserve life or take action that will prevent an incident deteriorating
- as soon as more resources are on scene stage 1 BA entry control must be implemented
- BA wearers will ensure tallies and gauges are checked time in recorded by BA team
- no more than two BA wearers will be in Rick area.
What happens when you take over the ECO board
- record time on board of take over, with name and rank.
- work out time of whistle
- fill in location of team
- not reset timer!
- write initial deployment on board
Criteria for stage 2
- greater degree of control and supervision for BA team
- more than BA entry control point
- more than six BA wearers
BA guidelines are required
When would a emergency team be deployed
- when any team fails to exit at time of whistle
- a DSU is heard unless notified it was an accident
- BA wearer in distress
- prolonged breakdown of communications
- BA wearer requested
Single BA wearer/modified stage 1
- undertaking low risk activities
- not within a building or structure
- can be seen by incident commander or nominated crew member
What duties of a BA wearer do you have
- don BA in safe air carry out pre-entry checks
- receive and confirm brief
- carry out buddy Checks
- work out turn around pressure
- hand BA tally to EXO before entering
- BA shuffle and search
- communicate with BA team members
How do you work out turn around pressure
Add 70 to your pressure after rounded down, and then divide by 2, and round upwards to closest 10
What are responsibilities of BA team leader
- receive and confirm brief
- co-ordinate gauge checks and return to ECP by time of whistle
- monitor working conditions and risk assesses progress
- provide updates to ECO
- decide when to withdraw
What is new entry
- team withdraws
- close down sets
- accept their tallies
- services set, changed cylinder, general check
- new brief to carry out another entry into risk area
- fresh records are required on ECO board
What is re-entry
- for clear specific task
- the cylinder contents of all wearers are sufficient for the task
- minimum pressure of all wearers 150 bar
- BA wearers must be fit enough for task
What must ECO considerations when re-entry
- notes re-entry in remarks
- works out of time of whistle for 150 bar
- must write 150 on cylinder pressure
- IC should try ensure rest of BA teams
What gets deployed when BA emergency
- send an additional appliance
- an ambulance
- officers
What you must consider before removing set going through a confined space
- it is necessary to remove set
- using this procedure uses a lot of air
- what’s on the other side
- good communication and teamwork are essential
Process of confined space
- assess size
- check other side with feet
- check gauge pressure
- remove dry and package up
- remove helmet
- feet first face down
- pull set as you do
- replace helmet when through
- put set back on
- check gauge
What is combustion
Fire is a chemical reaction in which fuel combines with oxygen, this is called combustion
What is pyrolysis
Is thermal decomposition of substance by heat
What are passive agents
Is something which absorbs heat from fire
What are fire gases
The products of combustion are known a large fire gases which consist of non flammable gases and flammable gases
What are limits of flammability
Gas will only burn during a certain limit too much or too much will not allow gas to burn. Lower limit known as LEL and upper limit UEL
Name the stages of a fire
- Early phase
- growth phase
- fully developed phase
- decay phase
What type of extinguish methods are there
- direct
- Indirect
- gas cooling
What is direct cooling
- technique narrow jet aimed based a seat of fire
- purpose applied in early and later stages of a fire. At seat of fire
Techniques of use of hose on a fire
- painting
- short pulse
- long pulse
- coning
How often should you do a gauge checks
- 3-5 minutes
- significant landmarks
- change of level
- ETAP
- casualty located significant event
What type of firefighting principles
- maintain position (stay)
- advance/move forward
- withdraw
How should you enter a a compartment
- short pulse
- control door and enter low, shout. Listen look with TIC
- assess condition stay, advance, withdraw
- enter low
