BSL Safety Permit turns the paper permit into a five-step digital workflow. Unknowns stay red until someone checks them on site, and every gate is enforced by the system, not by memory.
The same flow works for a mixer crane breakdown, a hot-work job on a ladle car, a confined-space entry into a gas main, or a planned shutdown. Each permit type brings its own hazards, energy sources, checklists and approval chain.
The demo data follows a 2×1300 t mixer bay crane that stops with a ladle on the hook.
Load, position, hazards and energy start as Unknown and block submission until verified.
Only an Isolation Authority can sign zero-energy, with isolation point and lock number.
Ordered approval chain, no self-approval, no one signs twice. Safety joins for critical hazards.
Two live permits on one asset are flagged, and Operations must acknowledge.
CO zones need a pass under 2 hours old. A failed retest stops the work automatically.
Maximum hours per permit type, one extension, and auto-suspension when time runs out.
Toolbox talk, PPE check, and an expired safety induction blocks the permit.
Any user can stop a job. It alerts the issuer and Safety, and logs a report.
Admins add permit types, hazards, energy sources, checklists and approval chains without code.
A secure REST API (JWT, OTP sign-in) drives the Android and iOS app. Every rule lives on the server, so the app can never skip a gate. Shop-floor staff can photograph evidence, record gas readings and raise a stop-work at the crane.
