Permit to Work System
1. What is the Work Permit System?
Permit-to-work system is a formalized process used by companies to manage and control high-risk activities to ensure that there is no harm to the health and safety of the workers. A permit-to-work system is an essential part of the risk assessment system as it finds out the different health and safety hazards possessed by the activities on board a vessel.
Permit to work system is a formal authorized system for controlling high-risk tasks. It is a system of work that contains predefined safety procedures. Permit to work system does not make the work safe rather it contributes to the safe working on board the vessel.

2. Importance of the work permit system
The importance of the work permit system can be defined in a way that it does not provide any type of safety or security to the personnel working on board but it guides or provides instructions regarding the commencement of work, types of equipment to be used while doing a particular work, PPE to be worn, etc. Hence work permit system is very crucial to be followed while doing any work that engages any type of danger to the vessel as well as the lives and properties on board.
3. Key Element of Work Permit
Permit to work is a formal document used on board that has to be filled by the personnel performing that task and it has to be signed by the authorized person or the officer on watch.
A permit to work includes crucial details filled out by the person performing the task i.e.
3.1 Job Detail
A person/worker who will perform some work has to describe the work like fixing a machine, working in an enclosed area, working on Monkey Island, etc.
3.2 Location
Specify the area where exactly you are going to do work, for example, if you are going to perform work on the Radar then you have to mention it so that OOW knows that someone is on the radar and hence he will ensure nobody should operate until work is done.
3.3 Date and Time
Mention the date and time when you plan to start and finish the work.
3.4 Tools and Equipment
Specify the equipment that you will use, ensuring that they are appropriate for the job.

The permit is valid for a specified duration, and it should be noted that the maximum permissible validity of any permit must not exceed 24 hours.
4. Types of Work Permits
There are mainly 10 types of permits to work:
4.1 Hot Work Permit
Hot work permits are the document required to be carried out before carrying out any type of hot work on board. Hot work refers to work involving open flames like welding, cutting, smothering, and other activities generating heat. The purpose of hot work is to assess the risks associated with hot work.
4.2 Enclosed Space Permit
These are required when entering into an enclosed space, describing the risk involved while entering an enclosed area. The hazard in enclosed space entry is the deficiency of the oxygen content in the area. Deficiency of oxygen can lead to the formation of hot spots and can affect the human body differently.
4.3 Cold Work Permit
These are required while working in an environment where the temperature is significantly lower than normal or working in a hazardous area, which does not create a source of ignition. Essential tasks such as connecting and disconnecting a pipeline, removing and fitting the valve, etc.
4.4 Working Aloft Permit
These are required for work involving working at a height of 1.8m or above the deck level that involves a risk of falling overside into the water, including working into the tank, working alongside an open hatch, or other openings.
4.5 Work on Deck During Adverse Weather
These are required when working on deck in adverse or bad weather conditions encountering extreme wind force and heavy rolling and pitching.
4.6 Electric Work Permit
This is the document required when carrying out electric work or on equipment where there is the risk of electric shock. Examples of such work include maintenance, installations, repair, or modification of electric systems and equipment.
4.7 High Voltage Work Permit
This is the document that has to be filled out before carrying out any type of high-voltage work. High-voltage work refers to the work on equipment or systems with a voltage of 1000 volts or higher.
4.8 Work on pressurized pipelines/vessel Permits
These are required while working on pipelines and vessels that are under pressure such as pneumatic lines, steam lines, hot water lines, boilers, compressors, etc.

- We have to specify the duration of a task.
- Discuss if any type of isolation is required during the task.
- A responsible officer along with the team leader, and task performer must ensure the completion of all preparation checks
- The task performer must countersign the permit and ensure that the permit is approved by the master.
