For facility managers, warehouse operators, building owners and engineering SMEs, controlling high-risk work is a daily operational responsibility. Maintenance activities may involve hot work, electrical isolation, work at height, confined spaces, hazardous energy or other conditions that require careful planning and authorisation.

A permit-to-work system provides a formal process for controlling selected or non-routine work activities. When that process is moved from paper forms, email chains and spreadsheets into a suitable digital workflow, SMEs can improve visibility, accountability and recordkeeping. However, the technology should support competent human assessment rather than replace it.

What is a digital permit-to-work system?

A digital permit-to-work system, or e-PTW, is an electronic workflow used to submit, review, approve, monitor and close permits for defined high-risk activities. It can capture information such as the work description, location, timing, hazards, precautions, responsible persons and approval status.

Singapore’s Ministry of Manpower describes permit-to-work systems as a formal authorisation process for selected and non-routine work. MOM also identifies electronic permit-to-work as a workplace safety technology relevant to facilities management, construction, manufacturing and marine operations.

In practical terms, an e-PTW system helps answer important operational questions:

  • What high-risk work is planned or currently active?
  • Who submitted and approved the permit?
  • Which precautions and isolations are required?
  • Where is the work taking place?
  • Are two activities potentially incompatible?
  • Has the work been completed and formally closed?

How e-PTW can improve safety for SMEs

1. Better visibility of active work

Paper permits can be kept in different locations, while approvals may be communicated through separate messages or conversations. A centralised digital system gives authorised users a clearer view of submitted, pending, approved, active and closed permits.

For a building owner or facility manager, this can make it easier to see whether contractors are working in occupied areas, plant rooms, loading bays or other sensitive locations. Dashboards and status views can support daily coordination without requiring staff to search through multiple records.

2. More consistent approval workflows

High-risk work should not begin simply because a form has been submitted. It needs review by the appropriate responsible persons, confirmation that controls are in place and approval through an agreed process.

Digital workflows can be configured so that required fields, review stages and authorised approvals are visible. MOM’s electronic permit-to-work specification template highlights the importance of configurable workflows and safeguards against skipped workflow steps. This can reduce the risk of incomplete submissions being treated as approved permits.

Nevertheless, workflow design must reflect the organisation’s actual safety responsibilities. Automation cannot determine whether a control is suitable in every site condition. Competent persons still need to assess the work and make informed decisions.

3. Stronger contractor coordination

SMEs often rely on external contractors for maintenance, cleaning, installation, repairs and specialist engineering tasks. When each contractor uses a different process, site teams may struggle to confirm whether risk information, method statements, permits and completion records are aligned.

An e-PTW workflow can provide a common submission and approval channel. Contractors can submit work details for review, while facility or engineering teams can check location, timing, hazards and required safeguards before work starts. Mobile submission and approval can also be useful for supervisors who need to manage activities from the worksite.

This does not remove the need for contractor induction, supervision or site inspections. It gives those activities a clearer administrative and operational structure.

4. Earlier detection of incompatible works

One of the most useful capabilities described in Singapore’s built-environment digitalisation guidance is the ability to detect potentially incompatible works. For example, simultaneous activities may create additional risks when they share a location, involve conflicting energy states or affect the same access route.

A digital dashboard can help responsible personnel compare work locations, schedules and activity types. Depending on the system configuration, it may flag possible conflicts for review. These alerts should be treated as prompts for competent assessment, not as automatic safety decisions.

5. More complete audit trails and close-out records

Safety management does not end when a permit is approved. The organisation may need to confirm observations, changes, extensions, handovers, incident information, reinstatement conditions and final closure.

Digital records can capture submissions, approvals, amendments, observations and closure reports in a structured format. IMDA’s e-PTW solution requirements also identify audit trails, reporting and business-data extraction as important capabilities. Over time, this information can help managers identify recurring delays, incomplete fields, repeated work locations or activities that require stronger planning.

A record is only useful if it is accurate, accessible to authorised users and supported by a defined retention and review process.

What should an SME look for in an e-PTW solution?

A practical solution should match the organisation’s work types, risk profile and operating capacity. Useful capabilities may include:

  • Digital submission of permits from desktop and mobile devices.
  • Work-location information, timing and activity categorisation.
  • Configurable review and approval stages.
  • Role-based access for requestors, approvers, supervisors and contractors.
  • Visibility of pending, active, expired and closed permits.
  • Notifications for required actions, expiry or changes.
  • Audit trails showing who submitted, reviewed, approved or amended a permit.
  • Dashboards and reports for operational review.
  • Data extraction for business or safety analysis.
  • Controls that prevent required workflow steps from being skipped.

AI features may be considered where they have a clearly defined purpose, such as helping identify possible conflicts or incomplete information. Any AI capability should be described transparently, tested against the organisation’s needs and kept subject to human review. An SME should not adopt an AI feature simply because it is available.

A practical implementation pathway

Start with a limited scope

Begin with a small number of high-risk work categories that create frequent coordination demands. Depending on the business, these may include hot work, electrical shutdowns, confined-space entry, work at height or maintenance involving hazardous energy. The selected categories should be based on the organisation’s own risk assessment and operating experience.

Map the existing process

Document how work is currently requested, assessed, approved, supervised and closed. Identify where delays, duplicated data entry, missing information or unclear responsibilities occur. This process map will help determine which workflow steps should be digitised first.

Define roles and approval authority

Clarify who can submit a permit, who reviews the controls, who approves the work, who can suspend or cancel it and who confirms closure. The system should reflect these responsibilities rather than creating a generic approval chain that does not match site operations.

Pilot at one site or workstream

Run a controlled pilot with a small user group. Measure practical outcomes such as submission completeness, approval visibility, contractor adoption, permit close-out and the handling of conflicting activities. Gather feedback from both office-based approvers and workers using the process on site.

Integrate progressively

After the core permit process is stable, consider links with contractor records, access control, maintenance management, electrical isolation planning, inspection records or incident reporting. Integration should reduce repeated work and improve information flow, not add unnecessary complexity.

Digital control still depends on people

An e-PTW system is an operational control tool, not a substitute for risk assessment, site supervision, training or competent judgement. A permit can be digitally approved and still be unsuitable if site conditions change, safeguards are missing or the work differs from the original description.

SMEs should define when a permit must be reviewed, suspended, revalidated or closed. Workers and contractors should also know that approval does not remove their responsibility to follow safe work procedures and report changed conditions.

Conclusion

For Singapore SMEs, digital permit-to-work systems can make high-risk work easier to coordinate and more visible across facilities, warehouses, engineering operations and building projects. The strongest benefits come from centralised submissions, clear approval authority, contractor coordination, conflict awareness and reliable audit records.

The most effective approach is usually a phased one: start with selected high-risk activities, configure workflows around real responsibilities, pilot the process and improve it using operational feedback. With the right implementation, digital tools can strengthen workplace safety management while keeping competent people at the centre of every decision.
