The real risks Construction & Trade Services lone workers face
Construction & Trade Services staff regularly work alone — in the community, on client sites, or out of hours. These are the hazards your lone working policy must address.
Falls from Height
The primary fatality driver, involving ladders, scaffolds, or fragile roof surfaces.
Falls from height account for 53% of construction fatalities.
Struck by Objects
Injuries from dislodged materials or swinging loads on fragmented sites.
Being struck by a moving object is consistently one of the top causes of fatal injury in the construction sector.
Tool Theft Aggression
Confrontations during high-value tool theft from vans or isolated sites.
86% of UK tradespeople worry about tool theft.
CDM 2015 / HSWA 1974
The Construction (Design and Management) Regulations 2015 mandate that all work must be appropriately supervised. For lone subcontractors without a supervisor on site, a verified check-in and alerting system is a practical way to meet that expectation.

HSE inspectors look for verified systems to monitor lone workers and summon help during incapacitation events.
How The Sentry maps to Construction & Trade Services risks
Each Construction & Trade Services hazard below is met by a specific Sentry feature — not generic safety software, but protection built for the way your teams work.
Falls or incapacitation
One-touch panic alarm
Domestic call-out conflict
Silent distress signal
Remote site isolation
Live location sharing
Built for the way Construction & Trade Services teams work

One-touch SOS
Fastest way to summon help on a busy or dangerous site.
Live GPS tracking
Real-time visibility for coordinators across multiple jobsites.

Every plan includes the full Sentry feature set
The same two-sided system — staff app plus manager portal — protects your Construction & Trade Services teams. No hardware, no IT integration, live in under an hour.
Home-screen widget SOS
Exclusive to The Sentry: fire the alarm, share your location, and start recording straight from a home-screen widget — one touch, without opening the app. In a real emergency, the extra steps simply aren’t there.
Loud or silent panic alarm
One alarm, two modes. Loud mode sounds an audible siren; silent mode is completely discreet for confrontational situations. Both instantly share live location with your managers and Nearby Team.
Automatic video capture
Recording starts the moment an alarm triggers. Unalterable footage is saved to the cloud audit trail, emailed as a view/download link, and kept on the handset. (Loud mode records video only; silent mode also captures audio.)
Lone Worker Timer
Session-based timed check-ins: set your own interval and the app prompts you to check in during a session. If a check-in is missed, help is escalated. Added specifically for the wider lone worker sector.
Fake phone call
Defuse a tense situation with a simulated incoming call that uses your phone’s native ringtone and generates a fresh caller number each time — so it appears entirely genuine.
Live location sharing (user-led)
Real-time GPS — but only during a work session you choose to start. The Sentry never tracks passively or automatically, so your personal time stays private. Privacy by design.
Private incident reporting
A confidential, whistleblowing-aligned channel to report harassment — with the option to submit anonymously. Once sent, no trace is left on the device: no email confirmation, nothing stored locally. Satisfies EHRC Step 4.
Friends & Family licences
Every staff member gets three free personal licences, so their family can use the same safety technology — entirely separate from the employer’s account.
Manager portal — included on every account
