Duties Of BA Wearer Flashcards
Siting ECO considerations
- As close to the incident as possible whilst maintaining safety
- In safe air so BA can perform pre-entry checks.
- If incident deteriorates you will not have to move.
- Easily found by all BA wearers.
- One ECP can cover more than one entry to risk area.
DUTIES of ECO
- ECO board, tabard and marker.
2.take up position as nominated by IC.
3.Annotate name, stage and Entry Control Point
4.Synchronise clocks
5.Receive tallies, check name and cylinder contents
6.Enter ‘Time In’ on each tally
7.Enter tallies and bracket, overwrite tallies with names and set no.
8.Work out time of whistle - also elapsed time if from initial
deployment
9.Identify team leader in ‘Location of Team’ column
Criteria for stage 1
Criteria:
The nature of BA operations is limited and not complex.
The incident requires no more than one BA entry control
point.
The incident requires no more than six BA wearers to be
deployed to the risk area at any one time.
BA guidelines are not required.
Rapid deployment
IC carries out assessment of the risks versus the likely benefits,
Resources available are limited.
A crew member, 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 resources become available, stage I BA entry control
procedures must be administrated.
BA Wearers will ensure tallies and gauges are checked and that tallies are placed in the BA entry control board, with time in’ recorded by
themselves and through an automated board,
No more than two BA wearers will be in the risk area:
Criteria for stage 2
The nature of BA operations are complex and require a
greater degree of control and supervision.
The incident requires more than one BA entry control
point.
The incident requires more than six wearers to be deployed
to the risk area at any one time.
BA guidelines are required,
Stage 1 modified criteria
Operations are not within a building or structure
Undertaking low-risk activities
The BA wearer’s gauge has been checked and their cylinder
contents recorded.
The BA wearer’s tally has been placed in a BA entry control
board with suitable and sufficient details entered.
The BA wearer can be quickly removed from the risk area
The BA wearer can always be seen my the incident
commander or other nominated crew member.
Taking over board after rapid deployment
Record time board is taken over
Not remove BA tallies from board work out (confirm) what time first crew entered the risk area
Work out time of whistle
Fill in ‘Location of Team*
Write ‘INITIAL DEPLOYMENT’ clearly in remarks
Not reset the initial deployment clock to zero until after crew have withdrawn.
Criteria BA emergency procedures
At least one BA team at each Entry Control Point.
Provision of emergency teams.
A minimum of two BA wearers required for every emergency team.
Numbers in the BA emergency team must be at least equal to that of the
largest BA team deployed from that ECP.
Cylinder capacity and duration of the BA sets must be at least equivalent
to the highest capacity and duration of those of the wearers in distress.
Same equipment used.
Provided with the equipment considered to be suitable and sufficient to meet the needs of all reasonably foreseeable emergency events.
Why would a BA emergency team be called in
a) Any team fails to exit by time of whistle b) A DSU is heard - unless by accident c) Audible or visual suggest a BA wearer is in distress d) Prolonged breakdown of communications e) Requested by BA wearer in the risk area.
The ECO monitoring the BA team will…
Establish and maintain communications
Record ‘time in’ on the BA entry control board
Ensure that BA tallies are filled in and placed in the BA ECB
Undertake other essential duties as required
Provide a handover to any subsequent BA entry control
operative.
Describe the EASE
300 Bar Regulator with gauge 3m of medium pressure hose with Y-piece coupling Carrying valise 300 Bar 6.7L BA Cylinder ADSU Drop-out key.
What to do when reaching a distressed BA team
Carry out gauge check of
emergency team members.
Inform BAECO that team has
been located and state exact
location.
Identify BA member that requires
assistance.
Silence ADSU using drop out key.
Check casualty’s cylinder and
assess if they have sufficient to
withdraw to safe air.
How do you connect the EASE
Connect EASE if required. Purge system by operating breathing valve purge button. Original cylinder can now be turned off if required leaving wearer breathing from the EASE cylinder. Consider placing carrying handle over casualty's head allowing bag to rest on chest and remove from risk area as quickly and safely as possible.
Duties of a BA team leader
Receive and confirm brief
Co-ordinate gauge checks and return to ECP by time of
whistle
Monitor working conditions and risk assess progress (stay,
advance, withdraw)
Provide regular updates to the ECO and update with
significant developments/actions
Decide when to withdraw from the risk area.
BA team checks before entering risk area?
Buddy checks: PPE, cylinder pressure, team communications
Thermal Image Camera is working
Radio communications with ECO
Torches are working
Work out turn around pressure
Fully understand the brief given by ECO and IC
Branch has water.
What is initial working duration
BA crews temporarily withdraw from risk area Crew do not remove face masks Crew do not close down cylinder Crew do not collect tally from ECO Crew immediately revisit the risk area No fresh records are required by ECO.
New entry?
Team withdraws from risk area
Close down sets
Accept their tallies
Services set, changes cylinder, general check
New brief to carry out another entry into risk area
Fresh records are required on ECO board.
Re entry
re-entry is for a clearly defined specific task
The cylinder contents of all wearers are sufficient for the task
Minimum pressure of all wearers is 150 bar
No doubts about the fitness of any BA wearer for the task to
be undertaken.
ECO considerations for re entry
ECO completes fresh details for a re-entry Notes 'RE-ENTRY' in the remarks column Works out 'Time of Whistle' for 150 bar Writes 150 in cylinder pressure column on tally IC should try to ensure rest for BA teams.
Name a few advantages of the smoke hood
Lightweight Can be attached to BA set Readily deployable Reduces manual handling issues No testing required (apart from ensuring bag is sealed prior to use) Casualty can move independently of rescuer
Name limitations of smoke hood
Will not support life in an oxygen deficient atmosphere Single use only Has a shelf life of 8 years Limited wear time, maximum of 15 minutes.
What provisions must the emergency team have
The team must be at least equal to that of the largest BA team
deployed within the hazard area from that entry control point.
The team must be provided with the equipment considered to be
suitable and sufficient to meet the needs of all reasonably
foreseeable emergency events.
The cylinder capacity and duration of the BA sets must be at least
equivalent to the highest capacity and duration of those of the BA
wearers.
Reasons why a BA emergency team can be sent into risk area
BA wearer fails to return by Time Of Whistle Activation of a Distress Signal Indications a BA wearer is in distress Prolonged breakdown in Communications Requested by a BA wearer.
BA ECO emergency procedures?
Contact all BA teams te ascertain their welfare Confirm if accidental activation or not Confirm with distressed team Location, injury, cylinder contents Inform IC
