what is process safety?
PTW is a documented control system requiring written confirmation
from authority persons that certain actions have been carried out
to eliminate or control risks before a high risk or non-routine
activity carried out.
Objectives
• To explain the Field local procedure for PTW
• To explain you Roles and Responsibilities within PTW system
• To display and classify different PTW and Certificate types
• To demonstrate the content of a PTW
• To demonstrate the correct PTW process steps 4
Operational proactive Control measures, which include documented
procedures, shall be established and maintained for those activities
associated with high priority risks identified during risk assessments
to ensure that these activities are properly controlled and managed.
A system that provides a formal safe control over facility activities
that are outside normal operating practice, or which have been
identified as being potentially hazardous
A PTW does not by itself make a job safe. Safety can only be
achieved by those planning, preparing and carrying out the work.
To ensure the PTW system is effective no attempt shall be made to
bypass it and Assesses and controls interfaces with adjacent plant
and workers (SIMOPS)
• Providing Information
• Allows for Planning
• Allows for Planning
• Allocate Accountability
Regardless the work to be performed, any Permit shall
have always the following documents attached:
1. Detailed Work Procedure/Work Method Statement
2. Risk Assessment Form
3. Tool Box Talk Form
4. Personnel List
Other Attachments
• Lifting Plan
• Confined Space / Vessel Entry Log
• Scaffold certificate
There isn’t any standard for the types of PTW, so it will be
according to organization procedures :
Cold work permit (not generate heat or spark)
Hot work permit (generate heat or spark)
Electrical work permit
Excavation work permit
Confined space entry permit
Hot work means work involving electric or gas welding, cutting,
brazing, or similar flame or spark-producing operations.
Hot work permit., The employer shall issue a hot work permit for
hot work operations conducted on or near a covered process.
The permit shall document that the fire prevention and protection
requirements of 29 CFR 1910.252(a) have been implemented
prior to beginning the hot work operations.
It shall indicate the date(s) authorized for hot work; and identify
the object on which hot work is to be performed. The permit shall
be kept on PTW office until completion of the hot work operations
Permit Office
A dedicated on site facility may be provided to co-ordinate the
PTW system for any designated PTW areas of operation.
- Copies of all PTW procedures and
documentation
- Manage live PTW in display boards
- Maintain: PTW, extended isolation and
authorised persons registers
- Provide appropriate ‘lock-out tag-out’ system
- Provide area classification information
Control PTW activity list
- Manage archive documentation
Fire prevention and protection according to NFPA51B (basic precaution).
All movable fire hazards in the vicinity shall be taken to a safe place.
If all the fire hazards cannot be removed, then guards shall be used to confine the
heat, sparks, and slag, and to protect the immovable fire hazards.
Combustible material. Wherever there are floor openings or cracks in the flooring that
cannot be closed, precautions shall be taken ( ex. Gas test clearance & LOTO).
Fire watchers shall be required whenever welding or cutting is performed in process
area.
Combustible materials are adjacent to the opposite side of metal partitions, walls,
ceilings, or roofs and are likely to be ignited by conduction or radiation.
Authorization. Before cutting or welding is permitted, the area shall be
inspected by the individual responsible for authorizing cutting and
welding operations.
Prohibited areas. Cutting or welding shall not be permitted in the
following situations:
1. In areas not authorized by management.
2. In sprinklered buildings while such protection is impaired.
3. In the presence of explosive atmospheres (mixtures of flammable
gases, vapors, liquids, or dusts with air).
4. In areas near the storage of large quantities of exposed, readily
ignitable materials such as bulk sulfur, baled paper, or cotton.
5. Ducts and conveyor systems that might carry sparks to distant
combustibles shall be suitably protected or shut down.
Hidden hazards to be considered in the hazard identification
to be able to identify the adequate control measures.
Employer and contractor shall be assigned a supervisor to
be responsible for the safe handling of the cutting or welding
equipment and the safe use of the cutting or welding process.
A welder or helper working on platforms, scaffolds, or runways shall
be protected against falling (second hazards).
Welding cable. Welders shall place welding cable and other
equipment so that it is clear of passageways, ladders, and
stairways.
Appropriate PPE shall be used for hot work activities.
Hot work inside confined space shall consider (ventilation and
O2 enrichment).
