INTRODUCTION TO PERMIT TO WORK

By: Khairul Anwar

PERMIT TO WORK

A permit-to-work system is a formal written system used to control certain types of work that are potentially hazardous.

A document which specifies the work to be done and the precautions to be taken.

Form an essential part of safe systems of work for many maintenance activities.

Allow work to start after safe procedure and provide a clear record that all foreseeable hazards have been considered.

A permit is needed when maintenance work can only be carried out if normal safeguards are dropped or when new hazards are introduced by the work.

Examples are, entry into vessels, hot work and pipeline breaking.

Essential features of permit-to-work systems are: Clear identification of authority of particular jobs, any

limits to their authority and who is responsible for specifying the necessary precautions.

Training and instruction in the issue, use and closure of permits.

Monitoring and auditing to ensure that the system works as intended.

Clear identification of the types of work considered hazardous.

Clear and standardised identification of tasks, risk assessments, permitted task duration and supplemental or simultaneous activity and control measures.

Essential elements of permit-to-work form

Permit-to-work systems are normally considered most appropriate to:

non-production work (eg: maintenance, repair, inspection, testing, alteration, construction, dismantling, adaptation, modification, cleaning etc).

non-routine operations.

jobs where two or more individuals or groups need to co-ordinate activities to complete the job safely.

jobs where there is a transfer of work and responsibilities from one group to another.

CONFINED SPACE WORK PERMIT

By: Umie Adilah

WHAT IS CONFINED SPACE?

A space that:

Is large enough and so configured that an employee can enter bodily and perform work.

Has limit or restricted means of entry or exit.

Is not designed for continuous human occupancy

EXAMPLES OF CONFINED SPACE

TANKS

MANHOLES

BOILERS

FURNANCES

SEWERS

SILOS

PIPES

TRENCHES

TUNNNELS

DUCTS

BINS

PITS

HOT WORK PERMIT

By: Nur Ellyna

HOT WORK PERMIT

Description Of The Work To Be Done:

Relatively few fires occur at permanent workstations specifically designed for hot work, such as the boiler.

Overheated Boiler: Heating unit reaches an exceedingly high temperature and pressure, and will not shut off.

This condition, a.k.a. Runaway Boiler, is considered unsafe and very hazardous to emergency responders and building occupants

Hazard Identification (boiler):

When boilers or furnaces experience an overheated condition, catastrophic damage to the heating unit, safety controls and components is likely.

Boiler pressures that exceed 15 PSI due to a failure of the relief valve can result in a violent explosion when the boiler vessel fails.

Precautions Necessary And Actions In The Event Of An Emergency:

Before issuing a hot work permit, the (PERMIT ATHORIZING INDIVIDUAL) PAI should examine:

the job site and

determine site specific hazardous processes, flammable/combustible materials,

and other fire hazards that are present or likely to be present.

The PAI should ensure the protection of all hazards in the following manner; Move the work to a designated safe location

Verify that there are no explosive that might be present and ignited

Reschedule hot work so that any operations with ignition sources are not running during the hot work.

Ensure that fire protection and extinguishing equipment are properly located at the site.

Check the job site periodically to ensure that the work can be safely continued.

HAZARDOUS WASTE PERMIT TO WORK

By: Syahira Syaella

Work to be Done

Planning

Supervisor and employee responsibilities and means of communication,

Name of person who supervises all of the hazardous waste operations, and

The site supervisor with responsibility for and authority to develop and implement the site safety and health program and to verify compliance.

Site Evaluation and Control A trained person conduct a preliminary evaluation of an uncontrolled

hazardous waste site before entering the site. The evaluation must include all suspected conditions that are

immediately dangerous to life or health or that may cause serious harm to employees (e.g., confined space entry, potentially explosive or flammable situations, visible vapor clouds, etc.).

Information and Training Program The employer must develop a training program for all employees

exposed to safety and health hazards during hazardous waste operations.

Both supervisors and workers must be trained to recognize hazards and to prevent them; to select, care for and use respirators properly as well as other types of personal protective equipment; to understand engineering controls and their use; to use proper decontamination procedures; to understand the emergency response plan, medical surveillance requirements, confined space entry procedures, spill containment program, and any appropriate work practices.

Example : MSDS

Personal Protective Equipment Program Include an explanation of equipment selection and

use, maintenance and storage, decontamination and disposal, training and proper fit, donning and doffing procedures, inspection, in-use monitoring, program evaluation, and equipment limitations.

Monitoring The employer must conduct monitoring before site

entry at uncontrolled hazardous waste sites to identify conditions immediately dangerous to life and health, such as oxygen-deficient atmospheres and areas where toxic substance exposures are above permissible limits.

Medical Surveillance

Hazard Identification

Methane gas is an odorless, colorless gas, or a colorless, odorless liquid in its cryogenic form.

Both the liquid and the gas pose a serious fire hazard when accidentally released.

Significant health hazard by displacing the oxygen in the atmosphere. The gas is lighter than air and may spread long distances.

Distant ignition and flashback are possible. The liquefied gas can cause frostbite to any contaminated tissue.

Precautions Necessary And Actions In The Event Of An Emergency

Personnel roles, lines of authority, and communication procedures,

Pre-emergency planning, Emergency recognition and prevention, Emergency medical and first-aid treatment, Methods or procedures for alerting onsite employees, Safe distances and places of refuge, Site security and control, Decontamination procedures, Critique of response and follow-up, Personal protective and emergency equipment, and Evacuation routes and procedures.

CONCLUSION

Permit to work are essential to prevent and control incidents of certain works that potentially hazardous.

The permit-to-work form must help communication between everyone involved in the production plant.

It should be designed by the company issuing the permit, taking into account individual site conditions and all the requirements.

Separate permit forms are required for different tasks, such as hot work and entry into confined spaces, so that sufficient emphasis can be given to the particular hazards present and precautions required.
