Construction lone worker safety

Every jobsite has someone working alone

Roofers three storeys up with no spotter. Excavation workers in trenches below grade. Finishing trades alone on site after the crew leaves. CheckMate gives your team the Safe Alone app, fall detection, satellite check-ins for remote sites, and 24/7 human operators who take action.

Common Challenges

The risks construction workers face on every jobsite

Heights without spotters, trenches below grade, remote sites with no cell signal — construction lone workers face the highest fatality rates of any industry.

01

Working at heights without a spotter

A roofer three storeys up. A scaffolding worker on the exterior of an unfinished building. A crane operator isolated in the cab. Falls are the #1 cause of death in construction — and when there's no spotter, no one sees it happen.

Automatic fall detection + 24/7 response

The SOS wearable detects falls and sudden impacts instantly — no button press needed. On sites with cell coverage, operators are alerted the moment it happens and dispatch emergency services to the worker's GPS location. For remote sites without reliable cell service, workers can pair the Safe Alone app with a satellite communicator like Zoleo (or add Rogers Satellite service to their phone) so alerts still get through.

02

Confined space entry

A worker enters a trench, a tank, or a crawl space — risking gas exposure, cave-ins, and structural collapse. No cell signal underground. No line of sight from the surface. If something goes wrong, no one above knows until it's too late.

Timed check-ins before entry

Workers set a check-in timer before going below grade. If the timer expires without confirmation, 24/7 operators begin escalation within minutes — no app required, a phone call from any line works.

03

Remote and rural jobsites

Highway construction, pipeline work, remote residential builds — the nearest hospital is 30+ minutes away and cell coverage is spotty at best. A serious injury in these conditions turns critical fast when no one can call for help.

Satellite coverage + GPS pinpointing

The satellite device sends check-ins and GPS location from anywhere — no cell towers needed. Operators know exactly where the worker is, even on a remote highway corridor or rural build site.

04

After-hours site work

Security guards, cleanup crews, finishing trades — someone is always on site after the main crew leaves. Alone in an unfinished building with open stairwells, exposed wiring, and no lighting. If they get hurt, no one finds them until morning.

Fall detection + scheduled check-ins

The SOS wearable monitors for falls through the entire shift. Scheduled check-ins — delivered via the Safe Alone app or a phone call — confirm the worker is safe at regular intervals, and missing one escalates to 24/7 operators immediately.

05

Heavy equipment operation

A solo operator on an excavator, loader, or crane — tip-overs, struck-by incidents, rollovers. These machines are loud enough to mask a cry for help, and operators are often the only person in that section of the site.

Impact detection via SOS wearable

The SOS wearable detects sudden impacts and falls from equipment — triggering an alert to 24/7 operators even if the worker is pinned or unconscious. GPS shows exactly where on-site the incident occurred.

Built for every construction role

From roofers to surveyors — everyone who works alone on the jobsite.

Complete Protection

Everything you need to keep lone workers safe

The Safe Alone app, SOS wearable with fall detection, satellite coverage, phone check-ins, and a live monitoring dashboard — all backed by a ULC-certified 24/7 response centre.

01

Safe Alone App

One-tap check-ins, instant panic button, and GPS tracking — all from your worker's smartphone.

02

Real-Time Dashboard

See who's active, who's checked in, and who needs attention — all on one screen. Map view with live GPS, status indicators, and compliance reports.

03

Satellite Coverage

Remote jobsites, rural builds, and highway corridors with no cell coverage. The satellite device sends check-ins and GPS location from anywhere — no cell towers needed.

SOS Wearable
04

SOS Wearable

Automatic fall detection for roofers, scaffolders, and crane operators. Triggers an alert if it senses a fall from height or sudden impact — even if the worker can't press a button.

Phone & Landline Check-Ins

Site office phone, personal cell, or any landline. Workers check in with a simple call — no app required, no special equipment needed.

How CheckMate Works

A simple, proven system that keeps your lone workers connected and protected — every shift, every day.

1

Check-In Prompt

Workers receive scheduled check-in prompts via the app, a phone call, or the satellite device on remote sites. One tap confirms they're safe.

2

Alert Triggered

Missed check-in? Our system immediately flags it. No delay, no assumptions — just instant awareness.

3

FAQ

Common questions from construction safety leaders

Yes. The SOS wearable uses accelerometer and impact sensors to detect sudden falls — from rooftops, scaffolding, ladders, or heavy equipment. When a fall is detected, an alert with GPS coordinates is sent instantly to our 24/7 monitoring centre. Operators attempt to contact the worker and escalate to emergency services if there's no response. No button press required — critical when a worker is unconscious or pinned.

Subcontractors download the Safe Alone app on their own smartphones — no special hardware needed. You can set up separate check-in schedules per trade or per site, and the dashboard gives your safety team visibility across all workers, including subs. For workers without smartphones, phone check-ins from any landline or the satellite device provide full coverage.

Yes — with the right device. Workers can pair the Safe Alone app with a satellite communicator like Zoleo (which uses the Iridium network), or add Rogers Satellite service directly to their phone. Both options let workers send check-ins and GPS location through a satellite link for highway construction, pipeline work, or rural residential builds. The stand-alone SOS wearable does not work in areas with no cell service, so it should be paired with one of these satellite options on truly remote sites.

Every Canadian province requires employers to have a working alone safety plan with regular check-ins and emergency response procedures. Bill C-45 adds personal criminal liability for supervisors and directors who fail to ensure workplace safety. CheckMate automatically documents every check-in, alert, and escalation with timestamps and GPS — creating a complete compliance audit trail.

Our ULC 5-Diamond certified monitoring centre operates 24/7 with live human operators. When a panic alert or fall detection is triggered, operators immediately attempt to contact the worker. If there's no response, they escalate to your designated emergency contacts and dispatch emergency services to the worker's GPS location — typically within minutes of the initial alert.
