What is a man down alarm and is it required for lone workers under New Zealand health and safety law?
A man down alarm automatically detects when a worker falls or becomes unresponsive and raises an alert without the worker needing to act[cite: 61]. Under the NZ Health and Safety at Work Act 2015, employers must have systems in place to respond to emergencies for workers in isolation [cite: 62].
Man Down Alarms and New Zealand’s Duty of Care
A man down alarm monitors a worker’s movement and orientation[cite: 64]. If the device detects a fall or extended period of inactivity, it triggers an automatic alert to nominated contacts or a monitoring centre[cite: 65]. Under the Health and Safety at Work Act 2015, PCBUs in New Zealand must eliminate or minimise risks to workers so far as is reasonably practicable[cite: 66]. For lone workers, an automated alert system is one of the most effective controls available [cite: 67].
Deciding Whether Your Workers Need Man Down Capability
- WorkSafe NZ expects controls that account for workers being unable to call for help [cite: 69]
- High-risk sectors including agriculture, construction, and utilities have clear need [cite: 70]
- Remote or rural workers are particularly exposed due to delayed emergency response times [cite: 71]
- The test is whether a conscious worker could realistically raise an alarm in the hazard scenario you’ve identified [cite: 72]
- Man down detection removes the assumption that they can [cite: 73]
Automatic Protection for Your New Zealand Workers
Guardian Angel Safety provides man down detection that works across New Zealand, including in areas with limited connectivity[cite: 75]. If a worker is incapacitated, our system raises the alert without them needing to do anything[cite: 76]. We support New Zealand businesses in meeting their WorkSafe obligations with practical, scalable solutions[cite: 77].
