Fire Safety in the Workplace: Essential Skills Every Employee Needs

Fire remains one of the most dangerous and destructive hazards in any workplace. A fire that starts small can grow to an uncontrollable blaze within minutes, threatening lives, destroying property, and shutting down operations indefinitely. While fire suppression systems and building codes provide important layers of protection, the single most critical factor in fire safety is the preparedness of the people inside the building. Every employee should possess basic fire safety knowledge, and employers in British Columbia have a legal obligation to ensure that this training is provided.

Fire Prevention: The First Line of Defence

The most effective fire safety strategy is prevention. The majority of workplace fires are caused by identifiable and controllable factors, including electrical faults, improper storage of flammable materials, unattended heating equipment, and careless disposal of smoking materials. A proactive approach to fire prevention includes:

• Electrical safety: Regular inspection of wiring, avoidance of overloaded outlets and extension cords, and prompt repair of damaged electrical equipment.
• Housekeeping: Keeping work areas clean and free of combustible clutter, ensuring that waste is disposed of properly, and maintaining clear access to exits and fire equipment.
• Flammable materials management: Storing flammable liquids and gases in approved containers and designated storage areas, maintaining proper ventilation, and keeping ignition sources away from flammable materials.
• Hot work controls: Implementing permit systems for welding, cutting, and other hot work operations, with fire watches maintained during and after the work.
• Equipment maintenance: Regular servicing of heating systems, cooking equipment, and any machinery that generates heat or sparks.

Understanding the Fire Triangle

To effectively prevent and fight fires, every worker should understand the fire triangle, the three elements that must be present simultaneously for a fire to exist: heat, fuel, and oxygen. Remove any one of these elements and the fire cannot sustain itself.

This concept is fundamental to both fire prevention and suppression. Fire prevention focuses on keeping these elements separated: storing fuels away from heat sources, controlling ignition sources, and maintaining proper ventilation. Fire suppression works by removing one or more elements: water removes heat, foam smothers and removes oxygen, and CO2 displaces oxygen from the fire.

Understanding the fire triangle also helps workers assess the risk of fire in their immediate work area. If flammable materials, potential heat sources, and oxygen are all present in close proximity, the conditions for a fire exist and additional precautions are needed.

Types of Fire Extinguishers

Not all fires are the same, and using the wrong type of extinguisher on a fire can be ineffective or even dangerous. Fires are classified by the type of fuel involved, and extinguishers are designed to address specific fire classes. Every employee should know which extinguishers are available in their workplace and which fire classes they are rated for.

Class A: Ordinary Combustibles

These fires involve common materials such as wood, paper, cloth, rubber, and many plastics. Water and foam extinguishers are effective against Class A fires. These are the most common type of workplace fire.

Class B: Flammable Liquids

Fires involving gasoline, oil, grease, solvents, and other flammable liquids require CO2, dry chemical, or foam extinguishers. Water should never be used on Class B fires, as it can spread the burning liquid and intensify the fire.

Class C: Electrical Equipment

Fires involving energized electrical equipment require a non-conductive extinguishing agent such as CO2 or dry chemical. Using water on an electrical fire creates a serious electrocution hazard. Once the electrical source is de-energized, the fire may be reclassified based on the remaining fuel.

Class D: Combustible Metals

Fires involving metals such as magnesium, titanium, sodium, and lithium require specialized dry powder extinguishing agents. These fires are uncommon but occur in manufacturing and laboratory settings. Standard extinguishers are not effective and can react violently with burning metals.

Class K: Cooking Oils and Fats

Kitchen fires involving cooking oils and fats require wet chemical extinguishers specifically designed for this purpose. These extinguishers create a foam blanket that smothers the fire and cools the oil below its ignition point. Class K fires are common in commercial kitchens and food service operations.

The PASS Technique for Using a Fire Extinguisher

Every employee should know the PASS technique, a simple four-step method for using a portable fire extinguisher effectively:

1. Pull the pin located at the top of the extinguisher. This releases the locking mechanism and allows the extinguisher to discharge.
2. Aim the nozzle or hose at the base of the fire, not at the flames. Directing the agent at the base attacks the fuel source where the fire originates.
3. Squeeze the handle slowly and evenly to discharge the extinguishing agent. Maintain a firm grip and controlled pressure.
4. Sweep the nozzle from side to side at the base of the fire until it appears to be extinguished. Watch for re-ignition and be prepared to repeat the process.

It is important to remember that portable fire extinguishers are designed for small, contained fires only. If a fire is too large to be controlled with a single extinguisher, if the room is filling with smoke, or if there is any doubt about safety, the correct response is to evacuate immediately and call the fire department.

Evacuation Procedures

When a fire alarm sounds or when a fire is discovered that cannot be safely extinguished, immediate evacuation is the priority. Effective evacuation procedures save lives, but they only work if everyone knows what to do. Key elements of a workplace evacuation procedure include:

• Know your exits: Every worker should identify at least two exit routes from their regular work area. Exit routes must be clearly marked, well lit, and kept free of obstructions at all times.
• Respond to alarms immediately: When the fire alarm sounds, stop work, secure any hazardous processes if it can be done quickly and safely, and proceed to the nearest exit.
• Do not use elevators: Elevators can malfunction during fires and may open onto a fire floor. Always use stairways for evacuation.
• Close doors behind you: Closing doors as you evacuate slows the spread of fire and smoke, potentially saving the building and the lives of anyone still inside.
• Check doors before opening: If a closed door feels hot to the touch, do not open it. The fire may be on the other side. Use an alternative exit route.
• Assist others: Help colleagues who may need assistance, including those with mobility limitations, but do not put yourself at risk in doing so.
• Proceed to the assembly point: Once outside, go directly to the designated emergency assembly point and report to the person conducting the headcount.

Fire Warden Roles and Responsibilities

Fire wardens, also known as fire marshals or floor wardens, are designated employees who take on additional responsibilities during fire emergencies. Their role is to ensure that evacuation proceeds smoothly, that all areas are cleared, and that emergency services receive accurate information upon arrival. Fire warden responsibilities typically include:

• Directing occupants toward the nearest safe exit during an evacuation
• Sweeping assigned areas to confirm that everyone has evacuated
• Assisting people with disabilities or injuries during evacuation
• Reporting to the evacuation assembly point with a status update for their assigned area
• Communicating with the fire department about the status of the building, the location of the fire, and any persons unaccounted for
• Preventing re-entry into the building until the all-clear is given

Fire wardens should receive specialized training that goes beyond general fire safety education, including hands-on practice with extinguishers, familiarity with building fire systems, and leadership skills for managing people under stress.

BC Fire Code Requirements for Workplaces

The British Columbia Fire Code establishes minimum requirements for fire safety in all buildings, including workplaces. Key requirements that employers should be aware of include the maintenance of fire alarm and suppression systems, regular inspection and servicing of fire extinguishers, maintenance of clear and unobstructed exit routes, posting of evacuation plans in visible locations, and conducting fire drills at intervals specified by the code. The local fire authority having jurisdiction may impose additional requirements based on the specific use and occupancy of the building.

Emergency Assembly Points

Every workplace must designate an emergency assembly point where evacuees gather after leaving the building. The assembly point should be located a safe distance from the building, away from fire department access routes, and large enough to accommodate all building occupants. It should be clearly identified and communicated to all workers during orientation and fire drills. At the assembly point, supervisors or fire wardens conduct a headcount to determine whether anyone is missing and may still be inside the building.

Fire Drill Best Practices

Fire drills are not a formality. They are the only way to verify that your evacuation plan actually works and that your people know what to do. Best practices for workplace fire drills include:

• Conducting drills at least once per year, and more frequently for high-occupancy or high-risk workplaces
• Varying the time and day of drills so workers experience different scenarios
• Simulating blocked exits to test whether workers know alternative routes
• Timing the drill from alarm activation to complete evacuation and headcount
• Debriefing after every drill to identify problems and areas for improvement
• Documenting drill results and corrective actions taken

How First Aid Training Complements Fire Safety

Fire incidents frequently result in injuries, including burns, smoke inhalation, lacerations from broken glass, and crush injuries from falling debris. Having trained first aid attendants on site means that injured workers can receive immediate care while awaiting emergency medical services. OFA-certified attendants are trained to assess and manage burn injuries, administer oxygen if available, treat for shock, and stabilize patients with multiple injuries.

Mainland Safety Training in Surrey, BC, offers comprehensive first aid programs including OFA Level 1, Level 2, and Level 3, as well as standard first aid and CPR/AED courses. Combining fire safety awareness with quality first aid training creates a workforce that can both prevent fire incidents and respond effectively when they occur.
