Supervisor Health & Safety Platform

Stop hazards before
they become incidents.

lumin42 gives UK site supervisors hands-free Voice Reporting plus short, practical safety refreshers built around HSE guidance and CDM 2015 — so hazards get logged on the spot, not lost in paperwork.

Built for UK sites · Supports SSSTS and SMSTS-trained supervisors · No app-store install required

The Problem

Paperwork is why hazards don't get reported.

Supervisors already know the risks. What slows them down is stopping work, finding a form, and typing a report on site with gloves on. So hazards get mentioned at the toolbox talk instead of logged — and the pattern never gets tracked.

  • Paper forms and clipboards get lost or filed too late to act on
  • Reporting apps require removing PPE and unlocking a phone one-handed
  • Safety managers can't see patterns across sites until after an incident
  • Generic safety training isn't tied to what's actually happening on-site
The lumin42 Fix

Speak it. It's logged, tagged, and routed.

Voice Reporting turns a spoken observation into a structured hazard report automatically — hazard type, location, priority, and photo, sent straight to the safety manager, with zero typing.

  • Hands-free reporting, even with gloves and PPE on
  • Automatic sorting by the main causes of fatal injury that HSE reports
  • GPS + timestamp tagging for every report, automatically
  • Toolbox talks and refreshers built around your site's actual hazards
Core Platform

Everything a supervisor needs on-site

One platform for training, reporting, and oversight — built for how supervisors actually work.

🎙

Voice Reporting

Speak a hazard or near miss and lumin42 transcribes it, sorts it and sends it to the right person, with no forms to fill in.

🎓

Supervisor Refreshers

Short refresher modules for working supervisors, tracked per site and per gang, with completion records. They support, and don't replace, CITB-accredited courses such as SSSTS and SMSTS.

📍

Live Hazard Map

Every voice report is geotagged and plotted in real time, so safety managers see recurring hotspots before they become incidents.

📊

Pattern Alerts

lumin42 flags recurring hazard types by trade, gang or location — so you fix the systemic issue, not just the one report.

🗣

Toolbox Talk Generator

Turns this week's actual voice reports into a ready-to-run toolbox talk, so training stays tied to what's happening on-site.

🛡

Audit-Ready Records

Every report and refresher is timestamped and exportable, ready for an HSE visit, a principal contractor audit or an insurance review. Incidents that may need reporting under RIDDOR are flagged so the responsible person can report them to HSE.

How It Works

From spoken hazard to closed report

No new hardware, no separate reporting workflow — supervisors use the tool they already carry.

1

Speak the hazard

Supervisor holds a button and describes what they see — in plain language, hands still gloved.

2

lumin42 structures it

Speech is transcribed and sorted by hazard type, then tagged with location, time and priority.

3

It's routed and tracked

The site manager gets an instant alert, the hazard is logged on the site map, and it's tracked until it's closed out.

Supervisor Curriculum

Refreshers built around what actually kills and injures on UK sites

Each module follows HSE guidance and the duties supervisors carry under CDM 2015.

01

Work at Height

The biggest cause of deaths at work. Edge protection, scaffold inspections, ladders and MEWPs under the Work at Height Regulations 2005.

02

Vehicles and Moving Objects

Plant, deliveries and falling objects. Traffic management plans, banksmen and exclusion zones.

03

Electricity and Services

Overhead lines, buried cables and live equipment. Safe isolation, permits to work and cable avoidance before digging.

04

Collapses and Machinery

Excavation collapse, temporary works and trapping in machinery. Inspections and who signs them off.

05

Accidents and RIDDOR

What to do in the first hour, investigating root causes, and which incidents must be reported to HSE under RIDDOR.

06

Briefings and Toolbox Talks

Site inductions, daily briefings and toolbox talks that people listen to, and escalating problems fast.
