Having the correct types of fire extinguishers on your premises is vital, but their effectiveness drops drastically if your team cannot find or reach them in an emergency. In a high-stress situation where a fire is rapidly spreading, nobody has time to search behind stock boxes or hunt through deep cupboards.
Proper placement is a core component of New Zealand safety standard NZS 4503. Here is a practical blueprint for correctly positioning fire extinguishers within your business layout to ensure compliance and maximum safety.
1. Keep Extinguishers Along Paths of Travel
Fire extinguishers should always be located along normal paths of escape and near room exits or corridor intersections.
The logic is simple: if an employee needs to use an extinguisher, they should move toward a safe exit route to grab it, rather than walking deeper into a confined, hazardous area to retrieve the equipment.
2. Follow the Travel Distance Rules
You cannot simply put one extinguisher by the front door and assume the entire building is covered. NZS 4503 outlines specific maximum walking distances depending on the fire hazard class:
Class A Hazards (Wood/Paper): A person should not have to walk more than 20 to 50 metres (depending on the building’s risk level) to reach an extinguisher.
Class B/F Hazards (Flammable Liquids/Cooking Oils): Because these fires spread aggressively, the maximum travel distance is much shorter—typically within 20 metres of the potential hazard source, but not so close that a fire would block access to the unit.
3. Observe Correct Mounting Heights
Extinguishers must never be left sitting loose on the floor where they can be knocked over, kicked, or inadvertently moved during daily operations. They must be securely mounted on dedicated wall brackets.
Weight under 4.0kg: The handle of the extinguisher should sit no higher than 1.5 metres above the floor line.
Weight over 4.0kg: Larger, heavier units must be mounted lower—with the handle sitting no higher than 1.0 metre above the floor—ensuring anyone can safely lift the unit off its bracket without straining.
Clearance: The base of the extinguisher should always remain at least 100mm off the floor to prevent rust and allow for easy cleaning.
4. Ensure High Visibility and Signage
An extinguisher must be visible from a distance. If it is tucked into an alcove or partially shielded by architectural features, you must install a compliant location sign (a red and white extinguisher symbol) high on the wall above the unit so it can be seen across the room over office partitions or retail racks.
5. Maintain the “Clear Zone”
The most common compliance failure we spot during workplace inspections is obstruction. Desks, filing cabinets, inventory deliveries, and even office rubbish bins frequently get pushed in front of safety gear.
As a rule of thumb, maintain a completely clear radius of at least 1 metre around every fire extinguisher, hose reel, and fire blanket at all times. Educating your staff to respect this “clear zone” ensures that when seconds count, the lifesaving equipment is immediately accessible.
