Q

The risk of collision remains during all phases of the inc, including driving away from scene.

The potential for further collisions are influenced by ?

A

Visibility:affected by fog,rain,sunshine,darkness and smoke

Road conditions: (snow,ice,rain,flooding,pot-holes)

Incident factors: (debris,damaged street furniture,oil/fuel,hazardous loads, smoke ,fire,time of day)

Road configuration: (bends,undulations,widths,access roads,class of road,road works,tunnels bridges)

Traffic: (speed,density,drivers slowing / fail to respond,cyclists)

Time personnel are on roadway:

People: casualties,onlookers public offering assistance

Driving on hard shoulder: surface does not offer same level of grip, may contain debris, being used by members of the public

Q

When an incident is on “class A” roads who may attend?

A

Highways agency : their principle role is to manage traffic, reduce congestion and improving traffic flow, but their primary role is to provide us with a safe working area.
The police retain overall primacy when they are in attendance at all inc
Ideally a coordinated response should be taken from all agencies in attendance. The IC should confirm with all agencies a understanding of establishing a safe working area on the roadway as the IC is responsible for the safety of LFB personnel and the impact of LFB operations on others.

Q

What are the operational safety considerations ?

A

High visibility of appliances and personnel is essential when working near moving vehicles esp roads with fast moving traffic /sharp bends or undulations
High vis clothing takes priority over requirement to wear any other identification tabard
Traffic tape and cones used to identify boundary of safe area to warn crews of moving traffic
Appoint safety officers to manage safe area of operations

Q

At RTC the IC actions must ensure that ?

A

Creation of Safe working area
Appropriate FF media
All fires extinguished
Ascertain: no/loc of persons trapped; no/loc of persons not trapped but require med attention,when practical thorough search of area as persons not always confined to vehicles or immediate area
If ambulance not in attendance Prioritise casualties
Assess and request resources required
Note FRU’s must NOT be returned where a “persons trapped” message has been sent

19
Q

To manage the incident the must consider ?

A

Early appointment of sector commanders and safety officers
Establish inner circle (2m around perimeter of vehicles)
Establish outer circle (5m around perimeter of vehicles)
Euipment and cut parts dump to keep working area clear of hazards

20
Q

When stabilising a vehicle, and isolating the vehicle electrical supply what needs to be considered?

A

The need for electrical system to wind down Windows and move seats etc (these should be completed prior to isolation)
the operating distance of Proximity keys varies they should always be considered live until keys is at least 20 away
Guidance for battery operated vehicles is on Auto-data via MDT

21
Q

FF’s at a incident who provide care to a casualty must do what?

A

Continue to do so until an appropriate suitable trained professional arrives at scene and is ready to take over
Wear examination gloves ( a new pair must be worn for each casualty to avoid risk of cross contamination )

22
Q

What needs to be remembered with supplementary restraints systems (SRS)

A

SRS consists of air bags/ seat belt pre-tensioners
Residual power in vehicle electric system may remain for up to 30min
SRS power connections will be coloured yellow
When airbag deployed in closed vehicle , it should be vented Asap
Deployed air bags should not be cut as this will spread residue further
Crash deploying roll bar systems on convertible cars activate using acceleration and tilt information in a RTC if the control is damaged there’s poss of post accident actuation with out warning and with considerable force/speed

23
Q

What are the considerations with duel fuel vehicles ?

A

The supplementary system may be powered by LPG, hydrogen or HV battery system
LPG involved in a fire, inc treated as a cylinder inc
LPG leaking & not involved treated as a hazards substance
HV electric system should always be treated as live even if engine not running removal of key and disconnection of 12v battery may not render all sources safe
HV cables are always coloured Orange

Q

What are the fend of positions for two way local road

A
