How Often Should Fire Risk Be Reassessed?

As one of the most important elements of workplace fire safety, it is essential to have confidence that your fire risk assessment is always up to date.

But how often should it be reviewed, and what types of changes might require an earlier reassessment?

This article explores these questions to help ensure you remain compliant with your legal responsibilities and maintain effective fire safety measures. To begin with, it is useful to revisit what a fire risk assessment is and why it is so important.

What is a fire risk assessment?

In the United States, employers are required to take appropriate measures to protect employees from workplace fire hazards under federal workplace safety requirements. OSHA's regulations include specific requirements for fire prevention plans, emergency action plans, portable fire extinguishers and other fire protection measures, depending on the workplace and applicable standards.

A fire risk assessment involves a thorough review of your premises to identify potential fire hazards and assess the level of risk they pose. This includes examining sources of ignition, combustible materials and the overall layout and use of the building.

Once hazards have been identified, appropriate measures can be put in place to reduce or eliminate risk. This may include removing hazards, improving fire detection systems or installing suitable fire extinguishers.

It is also essential to identify individuals who may be particularly vulnerable in the event of a fire. This could include people with mobility limitations, those working in high-risk areas, or individuals who are unfamiliar with the building.

Based on this assessment, appropriate emergency action and evacuation procedures should be established, and employees should receive the necessary fire safety training so they understand how to respond in the event of a fire.

How often should fire risk be reassessed?

Regular review is an essential part of the fire risk assessment process. U.S. federal regulations do not establish one general timeframe requiring every workplace to conduct a complete fire risk reassessment. However, fire prevention and emergency procedures should be reviewed and updated when conditions change or when necessary to ensure that fire protection measures remain effective.

In practice, it is important to review your fire risk assessment regularly to ensure that new hazards are identified and that existing safety measures and procedures remain effective.

In addition to these regular reviews, a new or updated assessment may be necessary when significant changes affect the premises, activities or working conditions. The frequency of these reviews should therefore be adapted to the level and evolution of risk within each organization or workplace.

When should a fire risk assessment be reviewed sooner?

The principles above should be considered general guidelines. To remain compliant with applicable requirements, your fire risk assessment should always reflect the current conditions of your workplace.

This means that if circumstances change, you may need to review or update your assessment sooner than planned. Common triggers include:

1 Changes in legislation

Any changes to applicable fire safety laws, regulations or standards should be reviewed to ensure that your workplace remains compliant with the requirements that apply to your operations.

2 Changes in building use

If the purpose or use of your premises changes, this may introduce new fire risks and require updated safety measures.

3 Alterations to layout or structure

Changes to the layout can affect evacuation routes, emergency lighting and fire safety signage, all of which may need to be reassessed.

If new employees or occupants require additional assistance in an emergency, your evacuation plans and procedures should also be updated accordingly.

Any of these changes may make your existing assessment out of date. Failing to review and update your fire safety measures can not only put people at risk, but may also result in non-compliance with applicable legal requirements.

Fire risk assessments should not be considered a one-time task, but rather an ongoing process that must evolve alongside your business. Regular reviews help ensure that your safety measures remain effective and that you are prepared to respond appropriately in the event of a fire.
