BA Entry Control Flashcards
BA Stage 1 is what and what 5 point to consider at stage 1
Stage I entry control is the minimum level of BA control necessary whenever BA is used. At BA stage I the following applies:
• To be used at incidents requiring limited numbers of BA wearers over a limited period of time.
• Limited to one entry control board (10 BA wearers). Now 6
• Limited to one entrance into risk area except where two entrances are close together and visible from a single entry control point.
• The IC should nominate a BA emergency team as soon as resources are available.
• When resources permit the IC may nominate a communications operative.
The Entry control board can provide a lot of information. What 10 things can it do/ show on one wearer?
The ECB also provides the BA entry control Operative (ECO) with real time information in relation to each BA wearer that has been logged onto the respective
ECB, such as:
• Time of warning/whistle calculated from remaining cylinder pressure and air consumption rate.
• Actual cylinder pressure in Bars.
• Elapsed Time (displayed as Time Rx on ECB) since loss of signal between ECB and BA set.
• Positive indication that a telemetry signal connection exists between the ECB and BA set.
• Alarm that a BA wearer has operated the ‘voluntary withdrawal’ button on the Bodyguard.
• Alarm that a BA wearer has actuated their Distress Signal Unit (DSU).
• Alarm that a BA wearer’s Automatic Distress Signal Unit (ADSU) has automatically operated.
• Alarm to indicate 10 minutes to Time of Warning/Whistle for individual BA wearer’s.
• Alarm to indicate Time of Warning/Whistle has been reached for individual BA wearer’s
What does the BA pouch contain?
On the front of the BA entry control board is a pouch, which contains the following items of equipment:
• BA entry control Operative tabard.
• A and B guideline tallies.
• Evacuation whistle.
• Black and White Chinagraph pencil.
Aide memoires 1-10 and 12&13
What are the aide memoires in the BA pouch?
Aide–memoires 1 to 10 and number 12 (note number 11 not in use).
1. Stage I entry control Operative duties.
2. Stage II entry control Operative duties.
3. BA main control Operative duties.
4. BA communications operative.
5. Distress to wearer procedure.
6. Cylinder procedure.
7. British Transport Police oxygen BA sets.
8. Respirator Entry Control.
9. Respirator Decision Tool.
10. Manual Log On and Log Off.
11. Not currently in use.- manual calculations
12. BA – maintaining telemetry signal – deployment options.
13. Emergency decontamination
What are the responsibilities of an entry control operative?
The ECO has the following routine duties at the re station:
Nominated ECOs must ensure that the following equipment is available:
• Entry Control Board.
• Contents of the ECB pouch - ECO tabard, chinagraph pencils, evacuation whistle, main guideline tallies, aide memoires (1-10 and 12).
• Guide Line in bag.
• Resuscitator (IEC pack): checked for cylinder contents, weekly tested if necessary. And AED tested
• Hand held radio for the ECO/communications operative.
• ECB tripod and bracket.
• Ensure the ECB is fully tested.
• Make sure the second set bags are available on re rescue units (FRU) command units (CU) and operational support units (OSU).
• Report any defects and/or missing equipment to the watch Operative immediately.
What are the important factors to consider when siting the entry control point?
• in a safe position
• as near the scene of operations as possible
• in safe air
• in such a position that it would not need to be moved should the incident deteriorate
Where would the entry control operative write the GTS number if the BA wearer is wearing one?
On the back of their tally
What has a ECO got to do to set up (fully set up) entry control for stage 1?
Having decided where to site the ECP, the ECO must:
• Set up the ECB and check the clock is set to the correct time.
• Maximise the telemetry signal by using the tripod and siting the ECB to reduce any obstructions between the board and the wearers. The ECB should also have its back to the wearers and the handles should not be held or obstructed.
• Enter location, stage, call-sign, roll and name on the BA entry control board.
• Don the ECO tabard.
• Set up the resuscitator ready for immediate use.
• Switch their hand held radio to the BA channel (6).
What actions should be taken by an ECO if the ECB they are using fails?
• The ECO should request a second ECB to use (they must not leave the ECB themselves).
• The ECO must maintain close contact with the BA wearers via radio communications.
• The time the ECB failed must be reported by the ECO to the IC and they must annotate the ECB accordingly.
• On acquiring the second ECB the BA tallies can be transferred, at which point the new ECB will update with the time of warning/whistle. All written information must be transferred onto the replacement ECB and the defective ECB retained at the ECP for reference.
• This second ECB must be operating with the BA tallies inserted and telemetry signal established within five minutes of the first ECB failing. If no second ECB is available within five minutes, or that also fails the IC must consider withdrawing the BA teams.
• If a prolonged loss of telemetry signal is experienced or the ECO has any concerns for the safety of the BA wearers then they must consider initiating emergency procedures and inform IC.
What are the points to consider for BA teams to have a Re-entry?
If, after withdrawing and closing down, a BA team is required to re-enter the risk area to perform a specific task, they may re-enter provided that:
• BA team members are fit for ‘re-entry’.
• All BA team members have a cylinder content of at least 190 bar. Pressures in excess of 190 bar will be recorded on the BA tally by the ECO as 190 bar for the purposes of the task and for control of the team.
• The task will be of short duration. The ’time in’ will be recorded on the BA tally and a TOW for 15 minutes later entered into the ‘Location’ column. The words ‘re-entry’ and the task being performed must be entered in the ‘Remarks’ column.
What are the point to consider for a new entry?
In exceptional circumstances the IC can re-use BA wearers when;
- no fresh wearers are available
- there is no reason to doubt those wearers’ fitness.
- Fresh ECB records are required.
A team withdrawing from the risk area and closing down may service their sets and change cylinders. Only one fire ground ‘A’ test may be carried out; following this a ‘B’ test is required.
Fire ground ‘A’ and ‘B’ tests must be recorded in the log book when returning to station. The ECO must be informed that a fire ground ‘A’ or ‘B’ Test has been carried out and note this in the remarks column on the ECB of the wearer. ‘B’ Tests on the fireground can only be carried out if the operational support unit is in attendance.
A BA emergency team must be what? 5 points to consider
An emergency team must be:
• Led by a minimum of crew manager.
• At least as large as the largest BA team or teams working together on the same task.
• Rigged to the same level of protection as BA teams already committed.
• Equipped with one second set for every two BA wearers in the emergency team.
• Equipped with BA radio communications for the team leader.
When must an Entry control operative immediately commit a BA emergency team? Does the ECO have to inform the IC first?
The ECO must immediately commit a BA emergency team and inform the IC if:
• A team or wearer has not returned to the ECP by their lowest ‘time of warning/whistle’ (either telemetry or manually calculated, whichever is earliest).
• An ADSU/DSU is actuated/indicated on the ECB.
• A BA wearer is in distress.
What is the definition of a “distress to wearer”
A DTW is defined as any malfunction of BA, which is likely to deprive the wearer of air or expose them to a contaminated atmosphere (this includes cosmetic smoke).
What are the duties of a radio communications operator? On where are they displayed?
The duties of a BA Communications operative are to:
• Don the ‘BA Communications operative’ tabard, obtain a hand held radio and switch to the channel being used by BA teams.
• Verify call signs and test communications with BA teams before they are committed.
• Stay next to and liaise with the ECO for their respective ECP.
• Pass messages relating to status changes of BA teams to the ECO, to record on the ECB.
• Communicate only with BA teams committed from their ECP.
• Respond immediately to priority messages.
• Prompt BA teams to take regular Bodyguard readings if telemetry is not working.
• In an emergency or a Bodyguard alarm is reported, confirm with the ECO and the IC and attempt to:
• Identify and locate the BA team in distress.
• Assist the ECO and IC to co-ordinate rescue operations using BA emergency teams and BA teams already committed.
