Smoke Alarm Installation — Safe Work Method Statement
Safe Work Method Statement for installing, replacing and interconnecting hardwired and 10-year lithium battery smoke alarms in houses, units and rental properties, including ceiling space work and ladder use.

Smoke alarm installation is usually not high risk construction work. Most alarms are fitted from a ladder below 2 metres, and hardwired alarms are installed with the circuit isolated. A SWMS is not legally required in those cases, but it is good practice and is often required by real estate agents, builders or the principal contractor. If the work involves a fall risk over 2 metres (stairwell voids, raked or high ceilings) or work on or near energised electrical parts, it becomes HRCW and a SWMS is required.
The hazards on smoke alarm jobs come from the setting rather than the alarm. Ladder falls are the main injury: technicians do many jobs a day, often on stairs, slippery floors and around furniture. Fitting a hardwired or interconnected alarm means running cable through ceiling spaces with all the usual risks: falling through the ceiling, heat, live cables, sharp roofing screws and, in older homes, asbestos. In the ACT and parts of NSW, some homes contain loose-fill asbestos insulation, so check whether the property is on a register before entering the roof. Rental and occupied homes add tenants, pets, children and dogs.
Alarm requirements differ between states and territories, including which rooms need alarms, whether they must be photoelectric, hardwired or interconnected, and how often rentals must be checked. Alarms must comply with AS 3786. Connecting a hardwired alarm to mains power is electrical work for a licensed electrician holding the licence required in your state or territory. Battery-only alarms may be fitted by a non-electrician, so check your state or territory regulator for the current rules.
Customise this template with the property address and type, the number and type of alarms (hardwired, interconnected wireless, 10-year lithium), the state requirements being met, the access method for each location, whether ceiling space entry is needed, tenant contact arrangements, and the licence details of the electrician.
Personal Protective Equipment
Risk Assessment
1.Arrival, access to the home and location check
| Hazard / Risk | Initial Risk | Control Measures | Residual Risk | Responsibility |
|---|---|---|---|---|
| Conflict with tenants, or injury from pets or children in the work area | Moderate | Confirm access arrangements with the agent or owner beforehand. Ask that pets are secured. Keep children away from the ladder and work area. If the occupant is aggressive or the home is unsafe to work in, leave and report to the office. | Low | Technician / Licensed Electrician |
| Alarm placed in the wrong location so it does not protect occupants | Moderate | Mark out alarm positions to the state requirements and the manufacturer's instructions, keeping clear of corners, air conditioning outlets, kitchens and bathrooms where nuisance alarms occur. Note any position that cannot meet the rules and tell the client. | Low | Technician / Licensed Electrician |
2.Ladder work to remove and fit alarms
| Hazard / Risk | Initial Risk | Control Measures | Residual Risk | Responsibility |
|---|---|---|---|---|
| Fall from a ladder on stairs, polished floors or rugs | High | Use a platform ladder or an industrial-rated step ladder on a firm, level surface, with rugs moved aside. Do not stand on the top two treads or over-reach; move the ladder. For stairwells and high or raked ceilings use a stair platform or stair-rated ladder, or treat the job as work at height over 2 metres and plan access accordingly. | Low | Technician / Licensed Electrician |
| Eye injury from dust when drilling ceilings | Moderate | Wear safety glasses when drilling overhead. Use a dust cup on the drill. Do not drill or cut ceilings suspected of containing asbestos (e.g. textured or fibre cement ceilings in older homes) until tested. | Low | Technician / Licensed Electrician |
3.Isolation and connection of hardwired alarms
| Hazard / Risk | Initial Risk | Control Measures | Residual Risk | Responsibility |
|---|---|---|---|---|
| Electric shock from existing alarm circuit or lighting circuit used to supply alarms | Catastrophic | Isolate the circuit at the switchboard, lock and tag it, and test for dead at the alarm base with a proven tester before disconnecting. Only a licensed electrician carries out mains connection work. Check whether the alarm circuit is shared with lighting and that it is RCD protected as your state requires. | Low | Licensed Electrician |
| Interconnect wiring connected incorrectly so alarms do not sound together | Moderate | Use the manufacturer's base and interconnect wiring or compatible wireless modules only. Do not mix brands unless the manufacturer states they are compatible. | Low | Licensed Electrician |
4.Ceiling space entry for cable runs
| Hazard / Risk | Initial Risk | Control Measures | Residual Risk | Responsibility |
|---|---|---|---|---|
| Falling through the ceiling | High | Enter only through the manhole with a ladder that extends at least 1 metre above the opening. Move only on joists or crawl boards spanning three joists. Use a head torch to see each step. | Low | Licensed Electrician |
| Exposure to asbestos, including loose-fill insulation | High | Before entry, check the age of the home and whether it is on a loose-fill asbestos register where one exists. Do not enter if loose-fill asbestos is present or suspected; report to the client. Wear a P2 respirator for general roof dust and old insulation. | Low | Licensed Electrician |
| Heat illness and contact with live cables in the roof | High | Do roof work early in the day in hot weather, keep visits short and carry water. Treat existing cables as live, do not handle damaged cables, and keep clear of downlight transformers. | Moderate | Licensed Electrician |
5.Testing, handover and disposal of old alarms
| Hazard / Risk | Initial Risk | Control Measures | Residual Risk | Responsibility |
|---|---|---|---|---|
| Alarms not working at handover | High | Restore power, then test each alarm with its test button and confirm interconnected alarms sound together. Record the alarm locations, type, expiry date and test result on the job sheet or compliance report for the agent or owner. | Low | Technician / Licensed Electrician |
| Hearing discomfort from repeated alarm testing | Low | Keep test presses short and step back from the alarm while it sounds. Use ear plugs for multi-alarm interconnection testing. | Low | Technician |
| Incorrect disposal of old ionisation alarms and lithium batteries | Low | Collect removed alarms and batteries in a box and send them to a recycler or the supplier's take-back scheme. Tape lithium battery terminals before storage. | Low | Technician |
