Fire Risk Assessment

A fire risk assessment is an audit of a building or structure to ensure the building is safe for its occupants from fire. Fire risk assessments are conducted on a methodical process which considers the likelihood of a fire starting and the consequence of a fire to its occupants. Depending on the requirements of the building and structure a fire risk assessment can also consider property protection and business continuity. Fire risk assessments are generally conducted on the following five steps.

  1. Identify the potential fire hazards including sources of ignition and sources of fuel
  2. Identify people at risk including people
  3. Evaluate, Remove, Reduce the fire risk with appropriate action
  4. Record, Plan, Inform, Instruct, Train the premises owner
  5. Monitor, Review and Revise the FRA at regular interval

Some complex fire risk assessments can also look further into issues related to property protection and business continuity. Under such circumstances some of the following factors are considered:

  1. Cost benefit analysis of fire safety measures
  2. Business continuity issue related to fire
  3. Specific high-risk activity which requires fire safety assessment
  4. Fire risk assessment for dangerous substance and explosive atmosphere
  5. Quantitative fire risk assessment based on historical data

Fire Safety Strategy

Developing a fire safety strategy is a process that ensures a building is safe by its design from fire. A fire safety strategy considers three main factors-

  • Life safety of the occupants of the building
  • Property protection of the building from fire
  • Business continuity

Fire strategies are produced at different stages of the project this includes RIBA Stage 1 to 7. A retrospective fire strategy can also be developed for buildings where there is inadequate information related to the fire safety design of buildings.

The primary objectives of a fire strategies are:
• Life safety of occupants – the occupants must be able to leave the building without being subject to hazardous or untenable conditions. This should be satisfied by meeting the Requirement B1 to B3 of the Building Regulations 2010.
• Protection of adjoining buildings – structures must not collapse onto adjacent property and fire spread by radiation should not occur. This objective should be satisfied by meeting requirements B4 of the Building Regulations 2010.
• Life safety of firefighters – Firefighters must be given a reasonable time to rescue any remaining occupants before hazardous conditions or building collapse occurs. This should be satisfied by meeting the Requirement B5 of the Building Regulations.

Fire Risk Appraisal of External Wall

A fire risk appraisal of the external wall and associated attachments (FRAEW), seeks to assess the level of risk to building occupants from a fire spreading over or within the external walls of the building, and to determine if the extent of fire risk is tolerable or is of such significance that risk-proportionate remediation
or further mitigation measures are considered necessary.

The type of buildings, of any height, expected to be within scope of such assessment are multistorey blocks of flats and include student accommodation, specialised housing, residential care and buildings converted into flats. Additionally, an FRAEW may be considered appropriate for other building types,
such as hotels.

The approach of the FRAEW is risk-based. Our methodology for undertaking the FRAEW follows the five-step basic level assessment approach detailed within PAS 9980:2022, as detailed below.

Step 1 – Confirmation that a full FRAEW is required.
Step 2 – Gather necessary building information.
Step 3 – Determine significant risk factors.
Step 4 – Evaluate risk factors against benchmark risk criteria.
Step 5 – Risk factor analysis to give overall risk level.
