     In the oil fields, all the pipes are carrying oil, gas or water. All these pipelines are pressurized with different pressures that vary from low to very high. The mistake in doing the incorrect isolation for any pressurized equipment for the required maintenance job will lead to a serious accident.

 

In the different types of factories we visited, they controled the different types of  instruments using instrument gauges. The instrument gauge is pressurized air that is cleaned from dust and moistures and used to control the different types of  control valves in the factories. 

 

These pressurized equipments are dangerous because the people can not imagine what a 50 PSI explosion could do to our body. It is a huge force that will hit us immediatly.
