A process Safety Gap Assessment is carried out to understand gaps in 100 % inherently safe virtual design against actual process design at site.
Although, this assessment is not intended to fully undertake a Process safety gap assessment the miniature analysis can be carried out to understand weather the full exercise is required at site or not.
A process safety gap analysis involves identification of deviations that can lead to
Containment failure of chemical process due to
Design pressure inadequacy,
Pressure relief system inadequacy (includes improper maintenance and design of the same),
Heating utility system control failure, Etc.
Ignition of flammable atmosphere
Presence of ignition sources + flammable atmosphere + oxidants together
Exposure to personnel, unintentional loss of environment due to
Lack of diligence to the same in design
Failure of containment of system due to faulty design, inadequate upkeep
