What is a Work Permit • A Work Permit is an Agreement which gives authorization for specific work activities to be undertaken ( Machine, Facility, Equipment or Structure ) the location and the time required to complete the assigned work • It is an agreement between the Issuer & receiver that the work to be done will be carried out in accordance with the provisions stated in the permit
Why a Work Permit ? • In the petrochemical industry, work must be done under controlled conditions to ensure the safety of workers and facilities. The Work Permit system was developed to provide safety in the workplace by controlling potential hazards inherent to the industry
PURPOSE OF PERMIT SYSTEM • Communication tool for understanding nature of the job and Identify related hazards • Safety checklist that ensures proper procedures,equipment and precautions are in place • Minimize risks to personnel and equipment

Cold Work • Work activity that does not produce a source of ignition for flammable mixtures • Examples • Any work which require opening vessels, pipes, manholes etc. • Erection / Removal of scaffolds • Insulation & painting jobs • Equipment greasing and lubrication • Machinery monitoring –including vibration instrument • Cutting of lines ( hacksaw/cold cutting )
Hot Work • Work activity capable of supplying ignition source for flammable mixtures • Examples • Process of joining together two pieces of metal ( Welding, brazing ) • Breaking of metal into two pieces ( Cutting) by means of extreme heat • Metal grinding • Use of IC engines • Sand Blasting • Drilling, Chipping • Photography • Torches and other open flames
Confined Space Entry • Is large enough and configured so that an individual can bodily enter and perform assigned work • Has limited or restricted means for entry or exit such as tanks, vessels, furnaces, boilers, excavations, pits, sumps, stacks, pipes etc. • Is not designed for continuous employee occupancy • May contain flammable, explosives, toxic or other harmful substance or oxygen deficient
Excavation Work • Use of Manual tools or mechanical excavator in digging a hole, pit, trench or any opening on the ground that is within the area covered and under the jurisdiction.
Vehicle Equipment Entry • Is the entry if Internal Combustion Engine vehicle or equipment in a designated hazardous area or at areas where there are potential presence of combustible or flammable gases or liquids, explosive dusts and other materials which are declared hazardous
Electrical Work Any work which requires a worker to do job on a dead or live electrical equipment, system,network or facility. Electrical Works include: • Energization & De-Energization • Trouble shooting • Preventive & Corrective Maintenance • Other such activities that are related to any source of electrical power
Hot Tapping The work that applies to welding connection made to pipeline or a vessel under pressure or has de-pressurized but has not been cleared for conventional construction method.It is also to be used where it is impractical to take equipment out of service
Definitions Gas Test :An instrumentation test of an atmosphere to determine oxygen, flammable gas, and/or toxic substance ( Benzene, hydrogen sulphide, carbon dioxide ) concentrations. A properly calibrated direct reading monitor shall be used for gas testing Hazardous Atmosphere :An atmsophere that may expose individuals to risk of harm from flammable gas or vapor – Airborne combustible dust – Toxic Gas or oxygen levels < 19.5 % or > 23 %
Definitions Hot Work :Job activities that include welding, torch cutting, open flame and /or grinding, or any other activity in the operating area that could be an ignition source Operations:In most cases operations are the owners and the Team Leader, Asst. Team Leader or operator will communicate with the lead worker about the job. All operators will be certified in work permit compliance training Exemptions:The Maintenance workshop is exempted from the work permit requirements as they pertain to source of ignition. It is the responsibility of the Maintenance Supervisor to ensure the work is done safely
