This page is part of the Oracle Safety PTW Knowledge Hub a series of connected guides covering every aspect of permit to work. It covers the three documented components of a competent PTW system: the policy and arrangements, the supporting procedures, and the permit forms. If you’ve arrived from the hub, this page sits at position 7 in the cluster.
PTW Policy and Procedures
A Permit to Work system is a formal, recorded process used to control work that has been identified as hazardous. When designed and used in accordance with law, guidance and recognised good practice, it helps ensure that health and safety controls are in place and functioning before work starts, while work is underway, and when work is completed or handed over. A Permit to Work is not a document. It is a control system — and like any system, it depends entirely on the quality of its component parts.
What is a Permit to Work system?
A Permit to Work system is a formal, recorded process used to control work that has been identified as hazardous. When designed and used in accordance with law, guidance and recognised international good practice, it helps ensure that health and safety controls are in place and functioning:
- before work starts
- while work is underway
- and when work is completed or handed over
A competent PTW system is documented in three connected ways:
- The Permit to Work policy and arrangements
- The procedures that support and give effect to the policy
- The Permit to Work recording forms
These elements are inseparable. Removing or weakening any one of them undermines the whole system.
The purpose of a PTW system is not to create paperwork. It is to make critical controls reliable, visible, and verifiable.
The three documented components of a PTW system
Every functioning PTW system is built on the same documentary structure.
1. The Permit to Work policy and arrangements
This sets the organisational rules, authority, and expectations for how the system operates.
2. Supporting procedures
These translate policy into practical, repeatable actions that reflect how work is actually carried out.
3. Permit to Work forms
These record decisions, confirmations, and handovers at the task level. None of these elements works in isolation. A well-designed form cannot compensate for weak governance. A policy without procedures is unenforceable. Procedures without competent people are bypassed.
Permit to Work policy and arrangements
The Permit to Work policy arrangement explains how the organisation plans, organises, controls, monitors, and reviews the PTW system. It should define clearly:
- when a Permit to Work is required and when it is not
- who has authority to approve, issue, suspend and cancel permits
- competence requirements for permit issuers and receivers
- interfaces with other control processes, including
- risk assessment
- isolation and energy control
- contractor management
- emergency arrangements
- how the system is monitored, audited and reviewed
This is not guidance. It is the rule set that gives the system legal and managerial force. Without clear policy arrangements, PTWs become optional paperwork rather than mandatory controls.
Permit to Work procedures
Procedures explain how the system operates in practice. They should cover, in clear and usable terms:
- how permits are requested
- how permits are issued and authorised
- how handovers between shifts or work groups are managed
- when and how permits are suspended or revalidated
- how permits are cancelled and closed out
Procedures must reflect reality. If they cannot be followed in the field, they will be worked around. When that happens, the system no longer controls risk, even if forms continue to be completed.
The Permit to Work form
The Permit to Work form is the document completed by a competent Permit Issuer, in conjunction with the Permit Receiver, to record the permit activity. There may be different forms for different types of work. Which form is used, and when, must be directed by the policy and supported by training. The PTW form must never be viewed as simply “permission to start a task”.
It is a record of control, capturing:
- task-specific hazards
- confirmation that required controls are in place
- isolation and verification where applicable
- supervision and handover arrangements
- suspension, reissue, and cancellation
The Permit to Work recording form does not create control. It records that control exists and remains valid. UK guidance on permit-to-work systems is published by the Health and Safety Executive in HSG250 and is worth consulting when designing Permit to Work forms. The original publication can be accessed here for the full guidance.
Permit to Work within the wider safe system of work
A Permit to Work must never be used in isolation from other formal control processes. In particular, it must operate alongside:
- Organisational policy arrangements Required by law, and essential to defining authority and accountability.
- Risk assessment Both general and task-specific risk assessments are legal requirements.
- Safe systems of work Any task requiring a Permit to Work must already have a defined safe system of work. The permit exists to ensure it is functioning as intended.
- Before-work job checks Dynamic checks carried out by workers or teams to confirm conditions have not changed.
Together, these elements form the overall safe system of work, particularly for tasks with a high consequence of failure.
Monitoring, assurance and review
Most Permit to Work systems do not fail suddenly. They fail through drift. A competent system includes arrangements for:
- monitoring live permits in the field
- sampling completed permits for quality and effectiveness
- learning from deviations, near misses and incidents
- auditing both compliance and system design
- reviewing and improving policy, procedures, forms and training
Without this feedback loop, PTW systems slowly become ritualised, even though the paperwork continues.
Legal status and consequences
Permit to Work policies and arrangements exist to give effect to statutory duties to protect health, safety and welfare.
In the UK, these duties arise principally from the Health and Safety at Work etc. Act 1974 and the Management of Health and Safety at Work Regulations 1999.
Where a Permit to Work system has been established to discharge those duties, it must be followed. Failure to do so has consequences for organisations, senior officers and employees alike.
More importantly, it removes a critical layer of protection from high-risk work.
