Safety

Permit to Work

No high-risk job starts without a signed permit.

Digital permits for work at height, hot work, confined spaces, excavation, lifting and electrical isolation. Each permit lists its precautions, collects approvals in order and is closed when the area is handed back.

Capabilities

Built for how sites actually run.

01

Permit templates

Each permit type carries its own precautions, gas test fields, isolation points and required approvers.

02

Ordered approvals

A permit cannot go live until every approver in the chain has signed, each with a time stamp.

03

Live permit board

See every active permit on the site plan, with time remaining and the crew working under it.

04

Clash warnings

Hot work near an active confined space entry, or lifting over an open excavation, is flagged before approval.

05

Shift closure

Permits expire at the end of the window. Closure confirms the area is safe and the crew is out.

06

Audit trail

Every request, approval, extension and closure is recorded and can be exported.
