Permit To Work (PTW) systems encourage project managers to identify potential hazards and work through action plans prior to executing the job, which helps to assure compliance with regulatory standards and enhances worker safety.

Prior to beginning work on a roof permit project, it must be reviewed and approved by subject matter experts and shift supervisors. At this stage, they can raise concerns about threats that the project manager may have overlooked.

1.   Hot Work:

The term “hot work” refers to any task that involves the use of open flames, sparks, or other forms of radiant heat. Typical examples of hot work include:

• Chainsaw slicing
• Welding sticks
• Soldering
• Grinding
• Hot riveting
• Utilizing tar boilers
• Use of open flames in any context
• Use of lead heaters and/or hot air blowers

The term “hot work” is used to describe any occupation where the use of heat creates hazards such as fire, explosion, or toxic gases. A hot work permit must be created, signed, and approved before any of these operations can be performed on the job. Hot work safety training is also required for anyone doing this kind of work.

2.   Cold Work:

Cold work refers to any potentially dangerous action in the workplace that does not involve or produce heat. These are some examples of cold work:

• Painting
• Operating equipment
• Using solvents or chemicals
• Erecting scaffolding
• Making use of hefty machinery
• Moving hefty items

It can be challenging for employers to know whether or not a certain cold work activity necessitates a permission to work due to the broad definition of cold work activities. To get the best guidance, consult a professional group like the Health and Safety Executive or the Institution of Occupational Safety and Health (IOSH).

3.   Height Work Permit:

Work that must be done at a height above the ground requires a height work permit if the worker’s safety could be compromised if they fell from that height. Height job often refers to any task that requires a worker to be at a height of more than 1.9 meters.

Workers at height are always at risk of harm, and in the worst-case scenario, death, should they fall from their position. Hence, men are only issued height work permits if they can show that they will be working with a full-body harness or safety belt.

4.   Confined Space Permit:

A restricted space entry permit is often referred to as a vessel entry permit. Equipment and spaces in several industries and workplaces can be categorized. A confined space is an area that is not designed for human occupancy but which personnel access is granted in order to complete a specific task.

Since entering a restricted place is the most dangerous type of entrance, special caution must be exercised while issuing confined space permits. Here are some of the possible checkpoints that must be passed before a vessel entry permission can be issued.

• Ventilation within the apparatus or vessel
• Oxygen content
• Proper lighting
• The existence of any gas or chemical
• Any internal machinery, such as the reactor’s agitator, must be deactivated.

5.   Excavation Work Permit:

Digging a hole, creating a pit, or removing soil are all examples of excavation. This license is typically needed on construction sites and in some industries for starting a new project.

If you need to do work at a depth of more than 1.5 meters below ground, you will need an excavation work permit. To prevent someone from falling into a pit with a depth of less than 1.5 meters, barricading must be used. An example of excavation work are:

• Pit construction
• Foundation digging
• Road cutting
• Underground pipe installation
