Health & Safety · Lone working

A lone worker app that makes sure someone knows you’re out

Start a session with where you are, what you’re doing, when you expect to finish and how often you’ll check in. Name the people to alert. Check in from your phone. If a check-in is missed, they are told, with how late you are.

OpSemble lone working screen with a running check-in session, countdown to the next check-in, escalation contacts and the list of everyone working alone right now

What you get

Check-in sessions

Site or location, activity, expected finish time and a check-in interval. Start it from the phone in the van, end it when you’re back.

Named escalation contacts

Each worker names the colleagues, or an email address, to alert. A session can’t start with nobody watching it.

Missed check-in alerts

A sweep runs every minute. Miss a check-in by more than the grace period and your contacts are notified with your last known location and how late you are.

Over-run handling

Running past the expected finish is itself something contacts should hear about. Checking in after an alert stands it down; a later lapse alerts again.

Monitoring for managers

Safety managers see every active session in the business on one screen: who is out, where, and when their next check-in is due.

Nothing to buy

Any phone with a browser. No dedicated device, no monitoring-centre contract, no per-device fee.

How it works

Name your contacts

Once. Colleagues in OpSemble or an email address.

Start a session

Location, activity, expected end, check-in interval.

Check in

A tap on the phone each interval. Run over and the session extends by another interval.

Miss one, and someone is told

Contacts get an alert with the session details. Check in to stand it down, or end the session when you’re back.

Lone worker software for businesses that don’t need a man-down device

This is a check-in and escalation system, not a certified man-down or fall-detection device, and it isn’t connected to a monitoring centre. If your risk assessment calls for those, you need a dedicated lone-worker service. If it calls for “someone knows I’m out and someone is told if I go quiet”, this is that, in the same app as the rest of your safety system.

Most lone working in small businesses isn’t a confined-space entry or a night shift on a remote site. It’s the engineer at a customer’s premises, the surveyor on a roof, the person locking up. The risk assessment says a check-in procedure is needed, and the procedure is a text to the office that nobody reads if it doesn’t arrive.

OpSemble makes the check-in the procedure. The worker starts a session with a check-in interval and named contacts, checks in with a tap, and a background sweep watches the clock. A missed check-in is the one thing in the product where lateness is the whole signal, so the sweep runs every minute rather than every quarter hour, and the alert to the contacts says how late the check-in is and where the worker said they were.

Because the session is a record in OpSemble Health & Safety, the manager’s monitoring screen shows every active session in the business, and the history is there for the day an auditor asks how lone working is controlled. The same people, sites and phones are used for permits, toolbox talks and incident reporting.

Starting and ending your own session needs only a login, not a safety-manager role, because the labourer with no H&S permissions is exactly the person who works alone. The module is £9 per user per month on top of a £29 platform fee, with a 14-day free trial and no card required.

Frequently asked questions

Is this a man-down or fall-detection device?

No. It is a check-in and escalation system on the worker’s own phone. If your risk assessment requires automatic man-down detection or a monitoring centre, use a dedicated lone-worker service alongside OpSemble.

Who gets alerted when a check-in is missed?

The contacts the worker named when setting up: colleagues in OpSemble or an email address. A session cannot be started without at least one contact.

How quickly is a missed check-in escalated?

The escalation sweep runs every minute. Once a check-in is later than the grace period, the contacts are notified with the session details and how late the check-in is.

What if the job runs over?

Checking in at or past the expected end extends the session by another interval rather than raising an alert. Running past the expected end without checking in does alert the contacts.

Can managers see who is working alone right now?

Yes. A monitoring view lists every active session in the business with location, activity and next check-in due. It needs the Health & Safety view permission.

What does it cost?

Lone working is part of the Health & Safety module at £9 per user per month, on top of the £29/month platform fee. 14-day free trial, no card required.
