Fire Risk Assessment

A fire risk assessment is a systematic evaluation of a building or workplace to identify fire hazards, assess the risk they pose, and determine the measures needed to prevent fires and protect people in the event of one. The assessment examines potential ignition sources, combustible materials, the people who could be at risk, and the adequacy of existing fire safety measures such as alarms, extinguishers, exits, and emergency procedures, then recommends actions to reduce the risk and improve safety. Fire risk assessments are an important part of fire safety management for workplaces and other buildings, supporting compliance with fire codes and occupational safety requirements. In the United States, fire safety is governed by federal OSHA requirements for workplaces, state and local fire codes, and standards such as those from the National Fire Protection Association. The assessment helps building owners and employers understand and manage their fire risks, protect occupants, and meet their legal obligations. Because identifying and controlling fire hazards is essential to safety and compliance, a fire risk assessment provides a structured way to evaluate and improve fire safety in a building or workplace.

Whether a fire risk assessment is legally required depends on the jurisdiction and the type of building or workplace, but fire safety obligations under codes and regulations apply broadly even where a formal assessment is not specifically mandated. In the United States, workplaces are subject to OSHA requirements that address fire prevention, exit routes, fire extinguishers, and emergency action plans, and state and local fire codes impose fire safety requirements on buildings, which fire marshals and code officials enforce through inspections and permits. While a formal written fire risk assessment in the style required in some other countries may not be universally mandated, the underlying duty to provide a safe environment and comply with fire codes and OSHA standards is a legal obligation. Certain occupancies, such as healthcare, assembly, and high-rise buildings, face stricter fire safety requirements. Because fire safety is governed by enforceable codes and regulations, building owners and employers must meet these requirements, and conducting a fire risk assessment helps identify hazards and ensure compliance. A fire risk assessment supports meeting fire safety obligations, which are legally required even where the specific assessment format is not.

A fire risk assessment evaluates the fire hazards present, the people at risk, the existing fire safety measures, and the additional steps needed to reduce the risk and protect occupants. It identifies potential ignition sources, such as electrical equipment, heating, cooking, and smoking, and the fuel sources, such as combustible materials and flammable liquids, that could cause or spread a fire. The assessment considers who could be harmed, including employees, visitors, and any vulnerable individuals, and evaluates the adequacy of fire detection and alarm systems, fire extinguishers and suppression, escape routes and exits, emergency lighting, signage, and emergency procedures and training. Based on this evaluation, the assessment recommends actions to eliminate or reduce hazards and improve fire safety measures and emergency preparedness. The findings help prioritize improvements and support compliance with fire codes and OSHA requirements. Because effective fire safety depends on understanding the specific hazards and the means of escape and protection, the assessment provides a structured evaluation of these factors. A fire risk assessment examines hazards, people, and safety measures to determine how to prevent fires and ensure occupants can escape safely, guiding improvements to fire safety in the building or workplace.

A fire risk assessment should be reviewed regularly and whenever significant changes occur that could affect fire safety, to ensure it remains accurate and the safety measures stay adequate. While the specific frequency can depend on the building, its use, and applicable codes, it is good practice to review the assessment periodically, such as annually, and to update it after changes such as alterations to the building or layout, changes in occupancy or use, the introduction of new processes or materials, an increase in the number of occupants, or after a fire or near-miss incident. Reviewing the assessment ensures that new hazards are identified and that fire safety measures, escape routes, and procedures remain appropriate for the current conditions. Fire codes and OSHA requirements expect employers and building owners to maintain safe conditions, which requires keeping fire safety measures current. Because fire risks change as buildings and operations change, an outdated assessment may not reflect the actual hazards. Regularly reviewing and updating the fire risk assessment, and after significant changes, keeps it effective and supports ongoing compliance and occupant safety in the building or workplace.

A fire risk assessment should be conducted by a competent person who has the knowledge, training, and experience to identify fire hazards and evaluate fire safety measures effectively. Depending on the complexity of the building and its risks, this may be a qualified internal staff member, such as a facilities or safety manager with appropriate fire safety knowledge, or an external fire safety professional or consultant for more complex or higher-risk premises. The person conducting the assessment must understand fire hazards, the relevant fire codes and standards, such as those from the National Fire Protection Association, and OSHA requirements, and be able to assess detection, suppression, escape routes, and emergency procedures. For high-risk or complex occupancies, such as healthcare facilities, assembly buildings, or industrial sites, engaging a specialist is often advisable to ensure a thorough and accurate assessment. The building owner or employer remains responsible for ensuring the assessment is carried out and acted upon. Because the quality of the assessment depends on the assessor's competence, it should be performed by someone with adequate fire safety expertise. A competent person conducting the fire risk assessment ensures hazards are properly identified and the safety measures are adequately evaluated.
