Questions from evaluators
Permit to Work software, answered plainly.
Yes. Teams can configure permit types, numbering, validity, approval roles, reassessment and reissue policy, work-party requirements, closure controls and phase-specific content. Templates are versioned so published changes do not rewrite permits already in progress.
Hot work, confined space, work at height, electrical, excavation, lifting and any site-specific type your process needs. Each permit type is a versioned template with its own modules, approval roles, validity rules and reassessment cadence, so one system covers every permit your site uses.
Yes. Risk assessments are completed as part of the permit process: a permit template can include a risk assessment block where hazards, controls and likelihood and severity ratings are recorded on the permit itself, or a pre-defined assessment the permit holder confirms and signs. RAMS can be created in Zentri or attached to the permit, so the assessment, method statement and authorization stay on one record.
Yes. A single job can carry several permit types for the same scope of work. Each type keeps its own requirements while the job shares one reference, work party, lifecycle and coordinated approval record.
Permit to Work authorizes the scope of work; Lockout/Tagout controls hazardous energy. They stay separate records with their own governance. Zentri links them through the same Job so coordinators see permit and isolation readiness together and can coordinate holds when conditions change.
Yes. Request, review, approval, issue, live control, reassessment, hold, handover, handback, restoration and closeout are all managed in Zentri, with every decision, signature, isolation and gas test recorded against the permit.
Permit templates define the active validity window, permitted extensions, reassessment cadence and the controls required for reissue. Work can be placed on hold, reissued through the configured level of review, and handed over to a new responsible person with the history preserved.
Yes. Permit templates can require training for the holder, the full work party or a named competent person. Zentri checks those requirements against current training records and can be configured to warn or to block authorization and reissue when a requirement is not met.
Yes. Zentri is a fully electronic permit to work system: permits are built, approved, issued, monitored and closed digitally, with paper forms rebuilt block by block so crews recognise what they sign. It is also a control of work platform, linking Permit to Work, Lockout/Tagout and the work-party register on one live job record.
