Types

Process Equipment Protection Basis	Mechanical Isolation Guidelines
Containment	The mechanical isolation device applied must be designed to survive the maximum explosion pressure for the process material, P_max. In addition, all of the piping and equipment upstream of the isolation device must also be designed to accept P_max. This may require a design pressure as high as 230 psig (16 bar).
Venting	The mechanical isolation device applied must be designed to survive the reduced explosion pressure of a vented deflagration, P_red. In addition, all of the piping and equipment upstream of the isolation device must also be designed to accept P_red. This will typically require a design pressure as low as 3 psig (0.2 bar).
Suppression	The mechanical isolation device applied must be designed to survive the reduced explosion pressure of a suppressed deflagratlon, P_red. In addition, all of the piping and equipment upstream of the isolation device must also be designed to accept P_red. This will typically require a design pressure as low as 2 or 3 psig (0.14 or 2 bar).
