Fire Protection - So, what are you doing?

Brad Parker stresses the importance of fire protection in a maintenance schedule

The tragic fire at Grenfell Tower in London in summer 2017 has focused property managers’ minds on fire protection. Under the Regulatory Reform (Fire Safety) Order 2005, all residential blocks must have an up-to-date fire risk assessment (FRA).

However, as the name suggests, this document only assesses the possible hazards that may be present in the common parts of a block of flats and recommends remedial actions. Simply having an FRA on file does not protect residents: if any recommended actions are not taken, property managers and right-to-manage freehold company directors could also be in breach of the regulations and face fines and/or prosecution in the event of a fire. Anyone with responsibility for managing a residential block must show diligence in servicing and maintaining the fire protection and life safety systems.

Taking responsibility

Two basic areas of fire protection are often not reported in FRAs: fire doors and fire stopping. Property managers should take responsibility for ensuring that these are regularly inspected by an expert. There should also be an emphasis on passive protection, as this is frequently neglected in inspections, and even in service and maintenance reporting.

Before calling in the fire protection experts, there is a lot that property managers can do themselves. As with any life-saving product, a fire door should be checked regularly to ensure it functions correctly and is ready to use. It should be tested in the same way as emergency lighting, a smoke or fire alarm, or a fire extinguisher would be. Any slight alteration to the door or its surroundings can affect its performance. Checks should be carried out at least every six months, or more regularly depending on the traffic through the door and behaviour problems in the block.

Maintenance Checklist

Property managers who are too busy to undertake these checks should employ a fire protection specialist to do so. A maintenance checklist should be used to ensure you inspect all the items correctly, in conjunction with your asset records, and should include the following.

Check the gaps around the top and sides of the closed door are consistently less than 4mm. You can use a £1 coin to give a feel for scale, as this is about 3mm thick

  • Are there any intumescent seals around the door or frame, and if so are they intact with no sign of damage? These seals are usually vital to the fire door’s performance, expanding if they become hot.
  • Are there smoke seals fitted and intact to limit the spread of smoke beyond the door? In existing buildings, the fire doors are often not fitted with these seals, and they should be upgraded.
  • Are the hinges fire-resistant and firmly fixed? There should be three or more of them, with no missing or broken screws.
  • Check the door closes properly: open it about halfway, then let go and allow it to close by itself. Does it close firmly on the latch, without sticking on the floor or the frame?

Fire doors should be fitted with a working self-closer [not all fire doors need self-closers i.e. riser cupboard doors / locked fire doors i.e. plant rooms, whereby a tradesman actually enters the area and needs to close/lock it on departing], otherwise they could seriously compromise the fire strategy of compartmentation. Entrance doors to individual flats are often not fitted with self-closers, and the opportunity should be taken to upgrade these if they open on to a staircase or escape corridor.

Preventing spread of fire

This can be restricted by subdividing buildings into discrete compartments. These are separated by walls and floors of a fire-resistant construction that hinders the spread of fire from one compartment to another. Normally, all fire compartments will have a fire door and can be readily recognised by property managers with the application of a “Fire door: keep shut” sign.

Examples of fire compartments – apart from individual flats in the block – are plant rooms electrical or water risers, and escape routes such as corridors or stairwells. Property managers or an appointed expert should assess the fire compartments in their blocks and then have these areas regularly inspected. This should be carried out in conjunction with another service and maintenance discipline such as fire door inspection, as you would have to open the fire door to inspect inside the compartment, or fire alarm and emergency lighting servicing. Evacuation or stay-put policies depend on compartmentation: this reliance is currently being challenged, however, so now is the time to review the fire evacuation strategy as well.

Fire-stopping is more specialised, requiring an expert eye to understand breaches properly. Again, property managers can do a lot to identify potential problems, and regular inspection is vital. For example, managers can visually inspect the following:

  • any new holes produced by building works, such as installation of a service – electrical cable or pipe – that is not sealed
  • existing holes that are reopened by removal of a service and not sealed
  • damage to cladding or boarding.

Inspection after building works have been completed is recommended, to ensure there are no breaches of the fire stopping. If this reveals incorrect cladding, boarding and other external systems – or even the lack of an external system – these should be checked by a specialist.

A fire-stop is defined in Approved Document B, Fire Safety, as “a seal provided to close an imperfection of fit or design tolerance between elements or components, to restrict the passage of fire and smoke”. Joints between fire-separating elements such as walls or floors should be fire-stopped to maintain the continuity of resistance. Openings for timber beams, joists, purlins and rafters, and pipes, ducts, conduits or cables that pass through any part of a fire-separating element should be minimised and kept as small as possible.

They should also be fire-stopped using:

  • cement mortar – although bear in mind that this can crack and fall out
  • gypsum-based plaster
  • cement- or gypsum-based vermiculite–perlite mixes
  • glass fibre, crushed rock, blast furnace slag or ceramic-based products, with or without resin binders
  • intumescent mastics
  • proprietary fire-stopping and sealing systems.

In the case of pipes or ducts, fire-stopping should allow thermal movement; experience shows that only proprietary – and expensive – fire-stop seals that fit fully around the cables or pipes are effective.


A client advised me that they have no control policy or terms and conditions stipulated in their orders to contractors to cover fire-stopping works. In such a case, property managers should act quickly to review and advise accordingly, as the contractor breaching of the compartments should be responsible for their fire-stopping. If the contractor cannot carry out certified fire-stopping where compartments have been breached, they should discuss this with the client and commission a specialist to complete the works. Building owners and managers will want to know this work has been completed quickly, in the event of a fire soon after any building works.

Remember, a legal liability will attach to responsible persons – which includes block managers and the freeholders – so regular inspection and documenting is vital.
