Building Regulations 2010 Approved Document B, states there should be access for a pumping appliance to within 45m of all points within any dwelling house to allow standard quick response hose reels to be utilised without the necessity for extending them, which would add valuable time to firefighting operations.
As the role of Fire and Rescue Services becomes more diverse, the amount of equipment required increases, the size of the fire appliance has also increased.
Access roads may be public highways, private roads, footpaths or specially strengthened and defined routes through the land surrounding the buildings, with minimum access requirements for access arrangements are shown in this section and are taken from the Building Regulations 2010 Approved Document B where applicable.
Consultation must take place with the Fire Authority during the early planning stages of any development or event to ensure adequate access. Applications must take account not only the access and working space requirements of standard fire appliances, but also specialist firefighting appliances with higher reach capacity such as Aerial Ladder Platforms (ALPs).
Access arrangements provided in this document should be considered when the designs of new developments are being planned. Failure to do so may prevent the applicant from obtaining a completion certificate under the Building Regulations, but more importantly, the lives of the occupiers will be put at risk.
Road Width
This dimension allows enough space for appliances to pass unhindered to the affected building accounting for the likelihood of parked vehicles. This also allows enough space around the vehicle to remove equipment quickly and efficiently from the appliance.
Gateway Width
The gateway dimension allows the new appliances which have a width of approximately 2.9m adequate clearance to enter a premises.
Turning Circle
Fire Service vehicles should not have to reverse more than 20m from the end of an access road. A turning facility will be required for any dead-end situation, where without this provision a fire appliance would be required to reverse more than 20m. One of the main concerns for Fire and Rescue Services would be the time taken to manoeuvre fire appliances if suitable turning facilities are not available. This situation would be compounded further where lengthy dead-end situations occur.
Height Clearance
This clearance allows fire appliances to manoeuvre under overhead obstructions such as archways, barriers and gateways. Consideration should also be taken where overhead obstructions such as cables and branches that line access routes may impinge on this required clearance.
Carrying Capacity
All roads that form part of the access arrangements for Fire and Rescue Service vehicles should be constructed to withstand a minimum weight of 16 tonne. This capacity takes into consideration the specification for new appliances.
Domestic Dwelling Houses
Vehicle access for a pumping appliance should be within 45m reach to the furthest point in the dwelling and measured from the rear ofthe fire appliance along a suitable hose laying path.
Every elevation to which vehicle access is provided should have a suitable door, not less than 750mm wide, giving access to the interior of the building.
Flats or Maisonettes
Vehicle access for a pumping appliance should be within 45m reach to the furthest point in the dwelling and measured from the rear of the fire appliance along a suitable hose laying path.
Other Buildings
The access requirements for other buildings will depend upon the total floor area and the height. (Further detailed guidance contained in Approved Document B Volume 2 - 2019 edition, Section 15: Vehicle Access.)
Buildings with Dry Risers
Building that have a Dry Riser installed should have access for a pumping appliance within 18m of all riser inlet boxes.
