Electronic Permit to Work & LOTO

In one sentence

Moves permits and isolation certificates off paper, so conflicting work on the same equipment is blocked automatically rather than caught by memory.

The problem

Paper permit systems depend on the permit coordinator holding the whole picture in their head. Conflicting isolations, expired permits and incomplete reinstatement are found during audits, and occasionally during incidents.

How it works

Permits, isolations and job safety analyses are managed digitally against the equipment register, with automatic conflict detection across concurrent permits on the same or interlocked equipment. Approvals are role-based and time-bound, and reinstatement is tracked to closure rather than assumed.

Data required

  • Equipment register with isolation points and interlock relationships
  • Permit types, approval roles and the operator’s safety procedures
  • Personnel competency and authorisation records
  • Integration with the maintenance work order system

What you get

  • Digital permits and isolation certificates with automatic conflict blocking
  • Live board of active permits by area and equipment
  • Audit trail of every approval, extension and reinstatement

What it cannot do

Conflict detection is only as good as the interlock and isolation-point model behind it, and building that model for an existing facility is a substantial engineering effort that must be done before go-live. Deploying this with an incomplete equipment model produces false confidence, which is worse than the paper system it replaced.

Every capability page states a real limitation. If a vendor cannot tell you where their product stops, you are not being told the truth about where it starts.
