what is Work Permit?
it is an official document gives a permission to do an industrial job, declaring the conditions in which the work will go safely in controlled conditions, and to take precautions required to control the hazardous involved in the working site.
the purpose behind Work Permit is to make sure that the works wanted to be done within the dangerous areas are done according to safety requirements as much as possible, and that the dangerous area has become safe before doing the required work.
Work Permit also identifies and evaluates hazards associated with any work to minimize the chance of those hazards into accidents.

Cold Work Permit:
this kind of permit is required when doing routine works that do not need using a flame, such as:
1. disconnecting oil, gas, and water pipelines, installing spades, or connecting flanges in their different types.
2. Chemicals pipeline and equipment.
3. working on machines, pumps, heat exchangers and other equipment.
Excavation Permit:
this kind of permit is required when doing any digging works within areas that may contain any pipelines or cables, it is required to get an approval from following parties:
1. Communication Personnel: to ensure that there are no communication cables within the digging area.
2. Electrical Personnel: to ensure that there are no electricity cables or wires within the digging area.
3. a professional personnel to ensure that there are no oil, gas or oil products pipelines within the digging area.
Constricted Areas Permit :
this kind of permit is required when doing any work within constricted areas such as: manifolds, oil well cellar, maintenance work inside a tank, vessel, separator, .. etc.
finally, why Work Permit is necessary?
it is an evaluation for hazardous conditions and is required to control the hazards involved in dangerous site and project activities. so everyone in the site should understand the precautions stated in the work permit to achieve the safety.
