The short answer
For prescribed fire extinguishers in Queensland buildings, plan for routine servicing every six months, alongside applicable annual and five-year maintenance tasks. The correct programme depends on the equipment and the building’s requirements. An extinguisher that has never been used still needs scheduled maintenance.

Which properties does this guidance cover?
This guide concerns prescribed fire-safety installations in commercial and other buildings covered by Queensland Development Code MP 6.1. Business Queensland identifies Class 1b and Class 2–9 buildings within its scope, including existing buildings. An ordinary Class 1a house is a different context.
Start with the site’s equipment register and maintenance records. A shop tenancy, warehouse and apartment common area can have different arrangements. Do not assume a neighbouring business’s schedule describes your obligations.
Are six-month and annual services different?
Yes. AS 1851 maintenance programmes include routine and longer-cycle tasks. FPA Australia explains that the annual extinguisher service includes the six-month tasks, rather than replacing them with a once-a-year-only programme.
Five-year maintenance does not mean every extinguisher must automatically be discarded at five years. The equipment type, condition and applicable maintenance requirements determine the work or replacement decision. Ask the service provider to distinguish routine inspection, longer-cycle work and any separately quoted replacement.
Is the service tag enough?
No. QFD’s fire-safety guidance says a tag, invoice or summary alone is not the required extinguisher maintenance record. Keep the detailed service documentation so someone taking over the site can understand what was inspected, the result and any corrective work.
Before approving a visit, ask where the records will be kept and who will receive them. After the visit, read the defects and recommendations rather than simply filing the invoice. If corrective work is separate from routine servicing, confirm who is organising it.

What should you notice between visits?
A scheduled service is not a reason to ignore a change on site. Without moving, opening or discharging equipment, staff can report obvious problems to the person responsible for maintenance.
- An extinguisher is missing, has been used or is no longer in its usual position.
- Stock, furniture or stored materials are blocking access or obscuring identification signs.
- Equipment or mounting appears damaged, or labels cannot be read.
- A layout, tenancy activity or storage arrangement has changed.
- A service date or outstanding recommendation is unclear.
What if equipment is overdue, damaged or used?
Contact the maintenance provider promptly and explain what you found. Ask how suitable protection will be maintained while the item is assessed or replaced. Do not wait for the next routine visit after a reported defect, and do not try to refill, repair or dismantle an extinguisher yourself.
For a multi-tenancy property, establish whether the installation is the tenant’s or the building manager’s responsibility. A written contact and escalation arrangement avoids assuming somebody else has arranged the work.
What should you send with a servicing enquiry?
Provide the site address or suburb, the number and type of extinguishers if known, the latest detailed service records and any reported defects. Tell us about locked rooms, tenant access and the person authorised to discuss repairs.
Sentinel can then discuss the portable-equipment work required and whether it should be coordinated with other fire or electrical maintenance. A clear equipment list is more useful than asking for a generic certificate without identifying the building’s needs.
