Introduction to Permit to Work Systems

In the bustling world of the petroleum, chemical, and allied industries, safety is paramount. One of the key tools to ensure this safety is the Permit-to-Work System. This system is a formal, recorded process used to control potentially hazardous work. It serves as a means of communication between site management, plant supervisors, and those who carry out the hazardous work.

Understanding the Basics of Permit to Work PTW Systems

A permit-to-work system is a formal written system used to control certain types of work that are potentially risky. It is a document which specifies the work to be done and the precautions to be taken. Permits are an essential part of safe systems of work for many industries.
Before initiating any task in a specific area, it’s crucial to ensure the safety of the environment and the machinery or equipment involved. To ascertain these safe conditions, a work permit system is implemented. This system specifies the conditions and procedures for the safe execution of work, allowing tasks to be carried out under controlled risk conditions.
A permit-to-work system is not just a permission to carry out a dangerous job. It is an integral part of a system that determines how that job can be carried out safely. The issue of a permit does not, by itself, make a job safe. That can only be achieved by those preparing for the work, those supervising the work, and those carrying it out. In addition to the permit-to-work system, other precautions may need to be taken, such as process or electrical isolation, or access barriers. These will need to be identified in task risk assessments before any work is undertaken. The permit-to-work system ensures that authorised and competent people have thought about foreseeable risks and that such risks are avoided by using suitable precautions.

Aim of the Work Permit System

The primary purpose of the work permit system is to ensure that:

Only authorized individuals are allowed to work in clearly notified hazardous areas.
The individuals permitted to work are aware of the various safety issues involved and understand that necessary safety precautions have been taken.
The work permit serves as a legal document between the issuer and executor for the commencement of a job inside a refinery.
The client has implemented the work permit system to distribute equal responsibilities for the job being performed.

The Importance of Permit-to-Work Systems in Hazardous Industries

The petroleum, chemical, and allied industries store and process large quantities of hazardous substances, including flammable and toxic materials. The potential for serious incidents is clear. To prevent such incidents, it is vital that there should be effective management of hazards, including the use of safe systems of work. A permit-to-work system is an integral part of a safe system of work and can help to properly manage the wide range of activities which can take place close to these hazardous substances.

Different Types of Permits

There are several types of permits, each designed to control specific types of work activities. These include Hot Work Permit, Cold Work Permit, Electrical Work Permit, Equipment Disjointing Certificate/Breaking Containment Permit, Confined Spaces Entry Certificate, Machinery Certificate, Isolation Certificate, Excavation Certificate/Heavy Equipment Movement Certificate, Radiation Certificate, and Diving Certificate. Each of these permits has specific requirements and control measures to ensure the safety of the workers and the environment.

The Evolution of Permit to Work Systems: From Paper to Electronic

The document is primarily written around well-established paper-based permit-to-work systems, but where possible it accounts for the newer medium of electronic-based permit-to-work systems. With the advancement of technology, electronic permits have become an integral part of permit-to-work systems. These electronic systems offer several advantages, including ease of use, improved tracking, and better record-keeping. They also facilitate the transition from paper-based to electronic systems.

The Purpose and Function of PTW Systems

The primary purpose of a permit-to-work system is to ensure the proper authorisation of designated work. This work may be of certain types or work of any type within certain designated areas other than normal operations. The system makes clear to people carrying out the work the exact identity, nature, and extent of the job and the hazards involved. It also specifies the precautions to be taken, including safe isolation from potential risks such as hazardous substances, electricity, and other energy forms.

The Role of Permit-to-Work Systems in Risk Management

A permit-to-work system aims to ensure that proper consideration is given to the risks of a particular job or simultaneous activities at site. Whether it is manually or electronically generated, the permit is a detailed document which authorises certain people to carry out specific work at a specific site at a certain time, and which sets out the main precautions needed to complete the job safely.

The Communication Aspect of Permit-to-Work Systems

The permit-to-work system is also a means of communication between site management, supervisors, and those carrying out the work. The system ensures that everyone involved in the work is aware of the risks and the necessary precautions. This communication is crucial to ensure the safety of all workers and to prevent accidents.

The Objectives and Functions of Permit-to-Work Systems

The objectives and functions of a permit to work system can be summarised as ensuring the proper authorisation of designated work, making clear to people carrying out the work the exact identity, nature, and extent of the job, and the hazards involved. It also specifies the precautions to be taken, including safe isolation from potential risks such as hazardous substances, electricity, and other energy forms.

When are Permit-to-Work Systems Required?

PTW systems are typically required for non-production work such as maintenance, repair, inspection, testing, alteration, construction, dismantling, adaptation, modification, and cleaning. They are also necessary for non-routine operations and jobs where two or more individuals or groups need to coordinate activities to complete the job safely. Additionally, they are used when there is a transfer of work and responsibilities from one group to another.

Identifying Situations that Require a Permit-to-Work System

Permit to work systems are normally considered most appropriate to non-production work, non-routine operations, jobs where two or more individuals or groups need to co-ordinate activities to complete the job safely, and jobs where there is a transfer of work and responsibilities from one group to another. However, permit-to-work systems should not be applied to all activities, as experience has shown that their overall effectiveness may be weakened. Permits-to-work are not normally required for controlling general visitors to site or routine maintenance tasks in non-hazardous areas.

The Limitations of Permit-to-Work Systems

While Work permit system are a crucial tool for managing hazardous work, they are not a panacea for all safety issues. They should not be seen as an easy way to eliminate hazard or reduce risk. The issue of a permit does not, by itself, make a job safe – that can only be achieved by those preparing for the work, those supervising the work, and those carrying it out. In addition to the permit-to-work system, other precautions may need to be taken, and these will need to be identified in task risk assessments before any work is undertaken.

The Role of Work permit system in Non-Routine Operations

Non-routine operations often involve a higher level of risk than regular operations. These operations may involve unfamiliar procedures, unfamiliar equipment, or working in unfamiliar areas. In these situations, a permit-to-work system can be particularly valuable. The system ensures that the work is properly planned, that all risks are identified and mitigated, and that everyone involved in the work is aware of the precautions they need to take.

Work Not Requiring a Permit

Routine work in established workshops and adjacent yards with boundaries.
Routine material handling work in warehouses and lay down areas.
Routine office work.
Visual inspection or checking without using any tools in operation areas with verbal permission from assistant custodians.
Work carried out by operation employees as part of their daily start-up and shutdown of the plant.
Work carried out in designated areas declared as work permit-free by the client.
Any work approved by the client on special request by the contractor.

The Essentials of PTW Systems

A permit-to-work system has several essential features. These include clear identification of who may authorise particular jobs and who is responsible for specifying the necessary precautions. The

The display of permits ensures that everyone involved in the work is aware of the permit and its conditions. The suspension of work allows for the safe stoppage of work if necessary. The handover of work ensures that when work is transferred from one group to another, all parties are aware of the status of the work and the precautions that need to be taken.

Understanding Permit Interaction and Hand-back Procedures

Permit interaction refers to the situation where multiple permits are in effect at the same time. This can occur when different groups are working on different aspects of a job, or when different jobs are being carried out in close proximity. The permit-to-work system should include procedures for managing permit interaction to ensure that all work is carried out safely. Hand-back procedures are also important to ensure that when work is completed, the site is returned to a safe condition.

Attachments of Work Permit

The work permit may require several attachments, including:

Work method statement
Work permit risk assessment
Issuer, Executor, and permit holder PTW card copies
Safety certificate of equipment
Lifting plan if lifting activity is involved
Drawing of location
Entrant & Attendant copy if it’s a confined space permit, etc.
