PN 754 Working On Roadways Flashcards
What two things must remain a priority throughout the inc ?
Crew and public safety
Hazard awareness.
The risk of collision remains during all phases of the inc, including driving away from scene.
The potential for further collisions are influenced by ?
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
name six additional hazards that may be present at the scene of a RTC?
8 given
Fuel fires:
Projectile and flame jet hazards: associated with gas struts,drive shafts units or pneumatic suspension systems.
Live supplementary restraint systems: not deployed
Alternative duel fuel vehicles: LPG or High voltage electricity
Electric systems:may remain live due to proximity keys, until system disabled
Vehicle contents:commercial freight may contain hazardous substance
Damaged car construction:sharp metal,glass,carbon fibres,plastics
Battery acid:
Biological: risks associated with body fluids.
The fire services act 2004 introduced new powers and responsibilities for FRS with regard to RTC - what are they?
(4 things)
In a emergency a FF may for the purpose of rescuing people/protecting them from harm:
- Move or break into a vehicle without consent of owner
- Close a highway
- Stop and regulate traffic
- Restrict the access of persons to the place concerned
When an incident is on “class A” roads who may attend?
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.
In the event of any disagreement between agencies regarding establishing a safe area of operations the IC should ?
Request the attendance of a LFB senior officer via control.
Pre-planning for roadways should include a awareness of ?
Access and exit points RVP Water supplies Drainage and water courses. This info will support safe and effective operations at inc and the potential affect on the environment,
What will increase levels of crew safety at incidents ?
Effective and regular liaison with other emergency services in order to understand their procedures and practices will improve levels of co-operation and increase levels of crew safety.
Awareness of adj FRS procedures essential where their is regular mutual assistance for “cross border” inc
Appliances and crews on approach MUST NOT?
On motorways and dual carriageways they MUST NOT cross central reservation or approach inc on the opposite carriageway
(Exception to this traffic stopped by police/HATO and only then under their direction)
Appliance MUST NOT stop in the outside lane at any time to inc on opposite carriageway (except where inc has spread across central reservation, then a fend off position must be adopted prior to ops commencing)
Where should appliances park at inc ?
pumping appliances In fend off before the inc
Special appliances beyond inc where possible / appropriate , creating the boundaries of safe working area
The IC must ensure on arrival that ?
. The size of the safe area created is suitable for the type and loc of inc
. Sufficient space is available to allow movement of FRS,equipment deployment of extinguishing media and access/ egress of other services
. Appliances positioned & illuminated with consideration to road layout such as bends /dips prevailing weather and lighting conditions
Where appropriate a request should be made to control for?
A message to be displayed on overhead gantries and matrix sights to warn approaching traffic
This request should contain as much relevant info as possible include road numbers, direction of carriageway,roadside marker posts,junction nos bridge or underpass Id’s or emergency telephone id’s
What are the operational safety considerations ?
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
Where LFB lighting is used what should be considered ?
Lighting should be provided to illuminate the scene without creating a hazard by dazzling other road users
Who does not need to wear Hi Vis ?
BA teams should not rig in Hi Vis But must only operate within the defined safe working area
Hazardous load identification may be established through ?
Vehicle / package markings
Hazard identification plates
Load manifest documents
Any action taken to open traffic lanes,remove debris,re-position
Appliance/emergency vehicles may ?
Have a direct impact on the safe area of operations the IC must make any any nec adjustments to maintain the safe area and inform all personal
At RTC the IC actions must ensure that ?
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
To manage the incident the must consider ?
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
When stabilising a vehicle, and isolating the vehicle electrical supply what needs to be considered?
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
FF’s at a incident who provide care to a casualty must do what?
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 )
What needs to be remembered with supplementary restraints systems (SRS)
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
What are the considerations with duel fuel vehicles ?
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
What are the fend of positions for two way local road
Fend off front and rear of inc across both lanes completely stopping traffic and making a safe area
What is the fend off positions for 3 lane carriageway with regard Hard shoulder Lane 1 Lane 2 Lane 3 Across central reservation
For all inc - pumps at front specialists at rear
Hard shoulder: fend off hard shoulder and lane 1
Lane 1: fend off part of hard shoulder and 1&2
Lane 2: fend off lane 1,2&3
Lane 3: fend off lanes 2&3
Across central reservation:fend off lanes 2&3 of both carriageways
who are the main partners in the road network?

Who can an ic request if a hazardous load is involved or suspected?
HMEPO
what are the three initial actions of the IC at an RTC?

If a persons trapped informative message has been sent, can IC’s still return FRUs?
NO!
what is the minimum inner circle zone around zone of operations?
2m
what is the minimum outer circle zone size, around the inner circle?

all SRS power connections are what colour?
yeller
when should hand held radios NOT be used inside a vehicle?
confirmed un-activated SRS

as a cylinder incident
what colour are High Voltage cables in cars?
orange - do not touch or cut!
what are traffic cones for and how far apart should they be?
designate safe area of work
to be placed 1m apart
who is responsible for closing and maintaining flow of traffic
police and highways agency
what needs to be done to implement “reverse access” (vehicles travelling against the flow of traffic)
police / HA have control of the head of the scene
confirm there are no vehicles between access point and the incident.
