Not every workplace needs the largest extinguisher on the wall. In offices, retail stores and small commercial spaces, the best extinguisher is often the one staff can confidently lift, carry and use in seconds. The 3.5kg CO2 fire extinguisher Perth strikes that balance, giving solid protection for electrical and flammable liquid risks in a more manageable size.
Like all carbon dioxide extinguishers, it puts out fire by smothering it with CO2 gas, then disperses completely. No powder clean-up, no damaged keyboards, no contaminated stock.
Not suitable for: Class F cooking oil and fat fires, and not recommended as the main extinguisher for Class A fires (paper, wood, fabric), as smouldering materials can re-ignite. Combine with an ABE powder or water extinguisher for full coverage.
Choose the 3.5kg when ease of handling matters and the electrical risk is moderate, such as offices, shops and clinics. For larger switchboards, plant rooms and industrial sites, our 5kg CO2 Fire Extinguisher offers more agent and a longer discharge. Not sure which you need?

Stay safe:
CO2 extinguishers have no pressure gauge, so the only way to confirm they’re full is by weighing them during inspection. Under AS 1851, workplace extinguishers should be inspected every six months, and CO2 cylinders also need periodic pressure testing. NeonSafety handles inspections, refills, servicing and test & tag across Perth, so you can tick fire safety off your list.
