Flashcards in PN466 Respiratory Protective Equipment Deck (38)
What is the default level of RPE for fires and other incidents presenting an acute respiratory hazard.
It is the default level of RPE for fires and other incidents presenting an acute respiratory hazard.
What is Acute respiratory risk?
Acute respiratory risk – this type of risk will be associated with hazardous atmospheres with the potential to cause immediate respiratory injury if the face mask were removed.
Is BA sector a functional sector?
BA sector – is a functional sector with a designated sector commander BA. This will support BA operations, resourcing and logistics and any other BA requirements (this is the new term for BA main control).
What does a Communications operative (Comms-Op) do?
The person responsible for maintaining communications between BA teams and entry control point (ECP).
When must a Entry control point supervisor (ECPS) be appointed?
Must be appointed when Stage II entry control is used.
Provides a greater level of control at an ECP.
Define New entry?
New entry – the BA wearer is wearing BA for the first or second time, the BA set has cylinder contents at or above the minimum entry pressure of 240 bar when reporting to the ECO.
Re-entry – the BA wearer has closed down BA set and is redeployed to complete a specific task that does not include firefighting (190 bar minimum and no longer than 15 minutes duration).
Explain Turn-around pressure (TAP)?
Turn-around pressure (TAP) – the pre-determined cylinder pressure at which the BA team should commence withdrawal from the risk area so that the ECP is reached before the low pressure warning actuates. This TAP should be reviewed by the wearers, although the ECO must be informed of any change (for example where wearers reach their TAP but are working very close to their known exit).
What is Turn-around point
Turn-around point – the pre-determined point at which the BA team will turn-around and withdraw from the risk area. This will be a location or landmark i.e. work and don’t go beyond the top of the stairs.
What is Turn-around time (TAT)?
Turn-around time (TAT) – the pre-determined time the BA team will begin to retrace their steps to withdraw from the risk area, timed and communicated by the ECO/ECPS i.e. to reduce BA team exposure to known extreme conditions.
Who can ask for BA to be worn?
BA is normally worn on the authority of the IC; however, personnel can request to wear it for respiratory protection.
What must be in place for BA to be committed to the risk area?
Personnel are only to be committed to the risk area wearing BA on the instructions of the IC once the required level of BA entry control is in place.
What must the nominated BA team leader have on them?
Exceptionally, there may be operational circumstances where one BA wearer for firefighting would suffice. What are they?
Examples of these circumstances include car fires, rubbish fires, hot cutting and working a monitor at the head of an aerial appliance.
When should an ‘A’ test carried out?
An ‘A’ test is carried out, when taking over a BA set, following a cylinder change and when nominated to test any ‘spare’ BA set.
Why can BARIE sets be worn into compartments where a potentially explosive atmosphere may be present?
They are the only radios that are intrinsically safe (hand held radios should be removed when replaced by BARIE sets in these circumstances).
If both telemetry and radio signal is lost the BA team must do what?
If both telemetry and radio signal is lost the BA team must withdraw to a point where communications can be restored. (This position should be landmarked for deployment of telemetry repeaters.)
Where a radio leaky feeder is in use BA teams will change radio to channel?
BA wearers reporting to an ECP shall?
Ensure at least 240 bar.
Check firefighting media.
Confirm nominated radio channel.
Ensure the tally is placed in the ECB.
Ensure a BA telemetry signal is established.
When visibility is impaired, BA team members must maintain close personal contact, in what order?
• Attachment by short BA personal line.
• Actual physical contact between each BA team member.
• Within physical touching distance.
Each wearer will consume air at a different rate, what do we do to keep on top of this?
Carry out regular pressure checks to monitor their consumption.
What is the minimum RPE level during damping down and cutting away operations?
Minimum RPE level is breathing apparatus.
What is EDBA not provided for?
It is not provided in order to increase the amount of work BA wearers can undertake within the risk area.
When must an IC nominate a BA emergency team?
The IC must nominate a BA emergency team as soon as resources allow.
The BA emergency team must be?
• Led by a minimum role of crew manager (CM).
• At least as large as the largest BA team or teams working together on the same task.
• Rigged to at least the same level of PPE/RPE as BA teams already committed.
• Switched to the same radio channel as BA teams already committed.
A nominated BA emergency team shall provide the following?
• An additional ECB set up and annotated ‘BA emergency team’ for use by the BA emergency team if committed.
• One ‘second set’ (select ECO’s BA set and include second set bag where available) carried by every two BA wearers in the BA emergency team (split tally from Bodyguard key and write ‘second set’ on the BA tally of the ‘second set’ and insert it into the ECB, bracketed together with the BA emergency team).
• A charged 45 mm second jet (if not already in place). Where resources allow this should be from an alternative pump and water supply.
During Stage I BA entry control how many wearers and how many ECP's?
Limited to six wearers deployed into the risk area at any one time.
Limited to one ECP.
Is the ECO responsible for the briefing and debriefing of BA teams?
This should be undertaken by the IC or SC.
BA wearers reporting to the ECO must have at least what bar cylinder pressure?
BA wearers reporting to the ECO must have at least 240 bar cylinder pressure
