One of the most common questions businesses and building owners have when arranging a fire risk assessment is how long the process will take. The answer depends on several factors, including the size and complexity of the building, its use, the number of occupants and the fire safety measures already in place.
A straightforward assessment of a small commercial premises may take considerably less time than an assessment of a large or complex building. At Fire Safety Compliance, our experienced assessors take the time required to properly understand your premises, identify fire hazards and assess the risks to occupants.
What Is Involved in a Fire Risk Assessment?
A fire risk assessment is more than simply checking whether fire extinguishers are present. The assessment involves looking at the building, how it is used and the potential risks that could affect people in the event of a fire.
Depending on the property, an assessment may consider:
- Potential sources of ignition
- Flammable materials and sources of fuel
- People who may be at particular risk
- Fire detection and warning systems
- Emergency lighting
- Fire extinguishers and other firefighting equipment
- Escape routes and emergency exits
- Fire doors and compartmentation
- Emergency procedures
- Staff training and fire safety arrangements
- Existing fire safety management systems
The assessor will also consider whether existing precautions are suitable and whether any additional measures may be required.
How Long Does the Assessment Take?
There is no fixed length of time for every fire risk assessment. The time required will depend on the individual circumstances of the building.
Factors that can affect the duration include:
Size of the Premises
A larger building naturally requires more time to inspect. Multiple floors, separate areas and extensive escape routes can all increase the scope of an assessment.
Complexity of the Building
Buildings with complicated layouts, multiple occupants or different uses may require a more detailed assessment than a simple office or retail unit.
Number of Occupants
The number of people using a building can affect the assessment, particularly where there are large numbers of occupants or people who may require additional assistance to evacuate.
Existing Fire Safety Measures
The condition and effectiveness of existing fire safety systems can also affect the assessment. Where further investigation is required, additional time may be needed to establish the extent of any issues.
What Happens After the Assessment?
Once the assessment has been completed, the findings are documented in a fire risk assessment report. This should clearly identify significant findings and any areas where improvements may be required.
Recommendations can help building owners and responsible persons understand what action needs to be taken and prioritise improvements based on the level of risk.
A fire risk assessment should not simply identify problems. It should provide useful information that can support the ongoing management of fire safety within the building.
How Often Should a Fire Risk Assessment Be Reviewed?
Fire risk assessments should be reviewed regularly and whenever significant changes occur that could affect fire safety.
This may include changes to:
- The building or its layout
- The use of the premises
- The number of occupants
- Fire safety systems
- Working practices
- Significant equipment or materials
A review may also be appropriate following a fire, near miss or identification of a significant new hazard.
