Compliance & Servicing

Fire extinguisher cabinets should have an intact break-glass panel as part of their standard operating condition under AS 2444. A broken panel is a compliance issue — it means the extinguisher can be accessed without breaking glass, removing the tamper-evident function. Replace the panel at the next service event after any breakage. Your fire protection technician will check cabinet glass condition at each 6-monthly AS 1851 inspection.

Frequently Asked Questions

When to Replace the Break Glass Panel

• After any emergency where the glass was broken to access the extinguisher
• After vandalism or accidental breakage of the cabinet glass
• When the glass is cracked but not yet fully broken — replace before it becomes a hazard
• As part of AS 1851 routine servicing when the technician identifies broken glass

Which cabinet does this break glass panel fit?

This 105mm × 105mm panel fits the current-generation 4.5kg fire extinguisher cabinet sold by Flamestop and available through Fire Extinguisher Shop. It may not fit older-generation cabinets with different panel sizes. If your cabinet has a different panel opening size, measure the opening before ordering. The large steel cabinet (suits extinguishers up to 9kg) uses a different panel size — confirm before purchasing.

How do I replace the break glass panel?

Remove the broken glass fragments from the cabinet frame carefully — use gloves to avoid cuts. Clean out the frame rebate to remove any remaining fragments. Slide or snap the new panel into the frame rebate. Depending on the cabinet model, the panel may be retained by a rubber bead, spring clips, or friction fit. Confirm the panel sits flush and is securely held before closing the cabinet door. Your fire protection technician can replace the panel as part of a routine service visit if preferred.

Is this the same as a perspex window replacement?

The break glass panel in a break-glass-access cabinet is designed to shatter easily when struck — allowing emergency access. Standard perspex (acrylic) is not appropriate as a replacement because it may not break consistently when hit. The correct replacement panel is specifically sized for break-glass function. The medium plastic cabinet (a separate product) uses a different panel type — replacement windows are not available for that model, and the entire cabinet must be replaced if the viewing panel is damaged.

How often does the break glass panel need replacing?

Only when it has been broken. An intact break-glass panel is not a consumable item — it should last the life of the cabinet provided it is not broken during an emergency or by accident. Your fire protection technician will check the glass at each 6-monthly AS 1851 inspection. If the glass is cracked (even without being fully broken), replace it before the next inspection to maintain the tamper-evident function of the cabinet.

Should I keep a spare panel on-site?

Keeping a spare panel is recommended if you have multiple break-glass cabinets in your building. After an emergency, replacing the glass promptly restores the cabinet’s tamper-evident function and confirms to occupants and inspectors that the extinguisher has been restocked and the cabinet returned to service. At $16 per panel, having a spare avoids a compliance gap while waiting for the next service call.
