Tunnels Flashcards
Where would the inner cordon in a tunnel be?
Initiating cordons in this infrastructure will normally incorporate portals, shafts, tunnel bores, cross
passages or stairs. This will normally mean that the inner cordon will be within the built infrastructure.
This may be used to assist the incident commander in defining sectors and controlling access and
egress.
How would the incident commander declare a major incident?
To declare a major incident, the incident commander should send the following assistance message to
Brigade Control: “This is a Major Incident, {Tactical Mode}…”
what is the purpose of BA Guidelines?
- BA teams to locate the scene of operations.
- BA teams to enter and search large or complex buildings or structures.
- Subsequent BA teams to locate other BA teams.
Official Policy number: 466
25 of 93 - A BA team in a risk area to retrace their steps to the ECP.
19.6 Main guidelines must be used
Due to the risk attached to sub surface incidents what measures should be implemented?
- These procedures may only be implemented when there is no evidence of unsafe conditions at
surface level.
Official Policy number: 467
4 of 10 - These procedures should not be adopted at sewer incidents or other risks where the presence of
unseen toxic gases may be expected. - All personnel proceeding below surface level must be equipped with a BA set and operate in
teams of two, until the incident commander (IC) decides that BA is not required. - A record of all personnel working below ground must be kept at surface level
How should main hose lines of greater than three lengths of hose consist of
should consist of 70mm hose from the
fireground pump, in order to reduce frictional loss. The final two lengths of hose line should
consist of 45mm hose to facilitate ease of movement for BA teams, whilst still producing an
effective jet from the available water supply.
When a BA team is required to engage in compartment firefighting, where necessary and as soon
as practicable supporting BA teams fully rigged in PPE and wearing BA should be provided to:
(a) Assist with the management of hose lines as the primary BA team progresses into the
compartment and ensure sufficient lengths of hose and weight of attack is available
(b) To protect egress/escape routes for firefighting BA teams with a jet made up of a 45mm
hoseline with a branch set at 230lpm or greater. It should be least one hose length longer
than the firefighting jet.
(c) Ensure that the BAECO has recorded the relevant information on the entry control board as
a point of reference and to keep track of BA wearers as per Policy number 466 – Respiratory
protective equipment – breathing apparatus – operational procedures
(d) Form emergency BA teams comprising the same number of personnel as the largest BA
team committed (as a minimum).
Control Information Form - carried on all appliances, FRUs and CUs. Each form has three copies to allow
annotation and distribution at the incident. where does white, yellow and blue copies go?
The top (white) copy of the form must be taken
to the Bridgehead (or other relevant area of operations) to provide resilience for handheld radio
communications. The forms are completed in BLOCK CAPITALS.
The other two copies (yellow and blue) are kept together as a record of the FSG call and also to record the progress of the rescue crews sent to the FSG caller(s)
If a person is seen lying on top of a transformer, switch, or, anywhere else above ground level , at which point can a rescue be carried out?
they must NOT be touched until word is received from an ‘authorised person’ of
the Electricity Authority that it is safe for rescue work to be carried out.
What voltage are the LFB Electrical gloves able to withstand
3300V or less,
When LFB forms only part of the attendance at a cross-border incident i.e. when an appliance
from the impacted FRS is also in attendance, who is responsible for the stop message
the host appliance will be responsible for any ‘stop’
messages.
When LFB crews form the sole attendance at a cross-border incident, the LFB appliance sends
the appropriate messages to the impacted FRS Control. The impacted FRS Control will provide
full details of the stop message and any other relevant information to LFB Control for post
incident data collection.
Do we record cross boarder incident indormation on the IMS system?
Upon return to station from a cross-border incident, LFB personnel will be expected to enter a
record into the incident management system (IMS). Therefore, sub/station officers will be
required to take note of incident information, messages sent or resources used for example, as
LFB’s ‘end of incident’ report will only hold limited details
In relation to a MTA, the following terms will be used to define different areas of the incident and
it is vital that their meaning is properly understood.
- Hot zone: an area assessed to contain a credible and continuing threat to life, including the
presence of attackers with weapons. - Warm zone: an area where the attackers are not believed to be present at this time, but an
identified threat remains. - Cold zone: an area where no known threat exists or where appropriate control measures
have been implemented, some cold zones will not require any control measures. - Limits of Exploitation (LoE): as a measure for mitigating risk to personnel operating in
zones, it is necessary that on scene commanders jointly agree and clearly stipulate the LoE –
the furthest points to which emergency responders will operate within such zones. - Casualty Collection Point (CCP): a staging area that enables lifesaving interventions to be
undertaken before removal to the Casualty Clearing Station. There may be more than one
CCP at a large incident. - Casualty Clearing Station (CCS): an area set up at the scene of an emergency by the LAS
in liaison with the medical incident advisor to assess, triage and treat casualties and direct their
evacuation. - Casualty Loading Point (CLP): an area near the Casualty Clearing Station, where
ambulances can be manoeuvred, and patients placed in ambulances for transfer to hospital.
What is a Planned evacuation?
– A pre-determined strategy for a premises to secure the removal of any persons in or around the premises to a place of safety. The responsibility for determining the strategy rests with the Responsible Person.
Emergency evacuation
The immediate and unplanned movement of people assisted by LFB personnel or other emergency responders away from actual or potential danger towards a place of relative or ultimate safety using recognised or normal means of escape, in
circumstances where:
− a planned evacuation (see planned evacuation above) strategy does not exist for the
premises and the IC decides that an emergency evacuation is necessary;
− the planned evacuation strategy has not taken place and the IC decides that an emergency
evacuation is necessary;
− it is determined that the planned evacuation strategy, including a stay put strategy, is no
longer tenable and/or is not working effectively.
It should be noted that both evacuation and emergency evacuation can be either full or partial
such as a wing of a hospital or a floor or a number of floors in a high-rise residential premises.
