Pick the modules, connect the hardware, and let AI agents watch every job.
Start with one critical workflow or switch on the whole EHS suite.
Digital PTW is natively connected to every selected module — one permit, one record.
Get this system scopedMost permit software is a form. Ours is the centre of a connected system: isolations, risk assessments, SOPs, toolbox talks, contractor clearance and training all have to agree before work is authorised.
The permit can’t go live until every isolation point is locked with a Smart LOTO® padlock and zero energy is verified.
AI isn’t a bolt-on. It sits on top of every module, reasoning over real isolation and permit records — not survey forms.
Assign a trained standby attendant before entry. SENTRY™ will re-check automatically when the permit is resubmitted.
