A fire extinguisher tucked behind a pallet, installed for the wrong type of fire or left unserviced may create a false sense of security when seconds matter. For Queensland employers, supervisors and contractors, knowing when are fire extinguishers required is not simply a purchasing question. It is part of identifying fire risk, providing suitable emergency equipment and making sure workers can respond safely without being put at greater risk.
When are fire extinguishers required in a workplace?
Fire extinguishers are generally required where a fire risk assessment, building fire safety requirements, a relevant Australian Standard, dangerous goods requirements or a site-specific rule identifies a need for first-attack firefighting equipment.
Under Queensland work health and safety duties, a person conducting a business or undertaking must provide and maintain a work environment without risks to health and safety, so far as is reasonably practicable. That includes managing foreseeable fire and explosion hazards. The exact extinguisher requirement will depend on the workplace, the activities performed, materials stored, building layout and the people who may need to evacuate.
A small office with low combustible load has different risks from a diesel workshop in the Bowen Basin, a farm shed storing fuels and chemicals, or a civil construction site where hot work is underway. One extinguisher type, location and maintenance approach will not suit every setting.
Building approvals and fire safety schedules can also set specific obligations for a premises. If a building’s fire safety documentation identifies portable fire extinguishers, the owner or occupier needs to ensure those installations remain available and maintained. For leased sites, responsibilities should be clear rather than assumed.
Start with the fire hazards, not the extinguisher cabinet
The right question is not, “How many extinguishers do we need?” It is, “What could start a fire here, who could be exposed, and what controls are needed?”
Common workplace ignition sources include electrical equipment, welding and grinding, vehicle engines, battery charging, combustible waste, cooking equipment, plant exhausts and overheated machinery. Fuels, oils, gases, timber, cardboard, grain dust, paints, solvents and lithium-ion batteries can increase the potential severity or change the type of fire that may occur.
A practical assessment considers whether a small fire could be safely controlled at an early stage. It also considers the more important alternative: whether people should evacuate immediately. Portable extinguishers are intended for initial response by trained people, only where it is safe to do so. They do not replace evacuation arrangements, emergency communication, alarms, fire doors, fixed fire systems or sound housekeeping.
For many workplaces, the assessment should be reviewed when there is a change in process, layout, plant, storage volume, workforce, tenancy or construction activity. A new battery charging station or a temporary hot-work area can alter fire risk considerably.
Selecting an extinguisher for the likely fire
Extinguishers need to suit the hazards present. Using an unsuitable agent can be ineffective or dangerous. For example, water should not be used on energised electrical equipment or flammable-liquid fires, while a standard extinguisher may not be appropriate for every battery fire scenario.
Common extinguisher agents include water, foam, dry chemical powder, carbon dioxide and wet chemical. Each has a different application and rating. Selection should account for the likely fuel source, the size of the risk, possible electrical hazards, wind exposure in outdoor areas, clean-up impacts and the ability of workers to use the equipment safely.
A dry chemical powder extinguisher is widely used across workshops, vehicles and general industrial areas because it can cover several fire classes. However, powder can reduce visibility, contaminate sensitive machinery and require extensive clean-up. Carbon dioxide may suit certain electrical or flammable-liquid risks, but it has limitations outdoors and in poorly ventilated spaces. Wet chemical extinguishers are used for commercial cooking oils and fats, not as a general-purpose substitute.
Australian Standard AS 2444 provides guidance on the selection and location of portable fire extinguishers and fire blankets. Other standards and codes may apply where specific hazards are present, such as flammable and combustible liquids, LP gas, dangerous goods or particular building uses. Use the current applicable requirements and seek competent advice where the risk is complex.
High-risk activities need close attention
Some work creates temporary fire risks that normal building equipment may not adequately control. Welding, thermal cutting, grinding and other hot work can produce sparks that travel well beyond the work area. Before work starts, consider the combustibles nearby, openings and voids, wind direction, fire watch requirements and suitable extinguishers at the point of work.
Plant maintenance, refuelling, spray painting, fuel transfer and electrical work also require task-specific controls. On construction sites, firefighting equipment may need to move as the project layout, access routes and work fronts change. An extinguisher in the site office is of little practical use to a crew working several hundred metres away.
Location, access and signs matter
An extinguisher can only help if it is quickly visible and reachable. It should be located along normal access paths, near the hazard it is intended to address and clear of obstructions. Do not hide extinguishers behind stock, lock them away, use the surrounding space for storage or place them where workers would need to move towards an established fire to retrieve them.
Appropriate identification signs help workers, contractors and visitors locate equipment quickly. Signage, mounting height, travel distance, coverage and the number of extinguishers required should align with the relevant standard, site risk assessment and building requirements.
Outdoor and remote locations present additional issues. Equipment can be exposed to dust, vibration, sun, corrosion and accidental damage. Mines, agricultural properties, transport depots and civil projects should consider whether extinguisher brackets, protective cabinets and inspection frequency are suitable for the operating environment.
Installation is only the beginning
A fire extinguisher is a safety-critical item. It needs routine inspection, testing and maintenance by a competent person in line with applicable requirements, including Australian Standard AS 1851 where relevant. Service tags and records should be legible and current, but paperwork alone is not enough.
Workplace checks should confirm that extinguishers are present, accessible, properly mounted, clearly signed, undamaged and showing no obvious signs of discharge or pressure loss. Damaged units, missing pins, broken tamper seals and blocked access need prompt action.
If the premises has a fire safety schedule or maintenance records required under building fire safety arrangements, keep those documents organised and available. This supports continuity when managers change, contractors are engaged or an incident occurs.
Workers need more than a quick instruction
Providing extinguishers does not mean every worker should fight a fire. Workers need clear emergency procedures: raise the alarm, contact emergency services where required, warn others, evacuate and go to the designated assembly area. They should understand that personal safety comes before property or production.
Where workers may be expected to use an extinguisher, practical instruction should cover the extinguisher types on site, the hazards they can address, when not to attempt firefighting, safe approach distances and evacuation triggers. Training should reflect the actual work environment rather than a generic demonstration.
For example, a transport operator may need to address vehicle and fuel hazards, while a kitchen team requires a different response to a workshop crew. Refresher training is particularly useful after changes to equipment, processes, staff or emergency arrangements.
A practical check for Queensland workplaces
If you are unsure whether your workplace has adequate extinguishers, walk the site with the fire risks in mind. Check the tasks being performed, fuels and chemicals present, electrical sources, access routes, existing equipment, emergency plan and maintenance records. Compare the findings with relevant building documentation and current standards.
Do not rely solely on what was in place when you moved into the building. Operations evolve, and so do the risks. A planned review is generally more effective than discovering a gap during an inspection, shutdown or emergency.
For employers across regional Queensland, Corrsafe can assist with practical workplace safety support, safety signage, equipment inspections and training that helps workers understand their role in an emergency. The aim is straightforward: provide equipment that suits the risk, keep it ready for use and ensure people know when to evacuate rather than take unnecessary chances.
A well-placed, properly maintained extinguisher is a small part of a larger fire safety system. Review it before the next job, site change or busy season, when there is time to fix issues safely.
