Requirements:
Procedures and Specific Requirements (5.2)

Design and Modifications (5.2.1)

Design requirements are itemized in Pressure, Vacuum, and Cryogenic Systems: Design Requirements [pdf].

Pressure Vessel Registration (5.2.2)

For instructions on filling out the form, see Pressure and Pressure, Cryogenic and Vacuum Systems: Pressure Vessel Registration Form (MESI) [pdf].

Testing (5.2.3)

For inspection requirements, see Pressure, Vacuum, and Cryogenic Systems: Testing Requirements [pdf].

Specialized Types of Systems (5.2.4)

Cryogenic Vessels and Systems (5.2.4.1)

The specific codes, regulations and requirements for installation of cryogenic systems and use of cryogen are detailed in Pressure, Vacuum, and Cryogenic Systems: Cryogen Requirements [pdf].

Vacuum Vessels and Systems (5.2.4.2)

Every vacuum system must be measured against criteria set forth in Pressure, Vacuum, and Cryogenic Systems: Vacuum System Requirements [pdf] in order to determine if the system requires HEEC review. The Vacuum Systems Consensus Guideline for Department of Energy Accelerator Laboratories provides additional requirements for vacuum systems across many DOE laboratories.

Refrigeration, Chiller, and Heating/Cooling Systems (5.2.4.3)

For requirements and codes, see Pressure, Vacuum, and Cryogenic Systems: Refrigeration, Chiller, and Heating/Cooling System Requirements [pdf].

Acetylene and Alternative Fuel Gases for Welding Processes (5.2.4.4)

In addition to the requirements for safe design, installation and use of pressure systems described in this chapter for fuels in fixed locations such as a welding shop, hot work activities are also regulated under specific codes that are listed in Pressure, Vacuum, and Cryogenic Systems: Requirements for Systems for Acetylene and Other Gases for Hot Work [pdf].

For more information on requirements for fuels in compressed gas cylinders, see Chapter 38, "Compressed Gas Cylinders".

Oxygen Systems (5.2.4.5)

Required codes, regulations, and additional design safety standards for oxygen systems are listed in Pressure, Vacuum, and Cryogenic Systems: Oxygen Requirements [pdf].

Hydrogen Systems (5.2.4.6)

Required codes, regulations, and additional design safety standards for hydrogen use are listed in Pressure, Vacuum, and Cryogenic Systems: Hydrogen Requirements [pdf].

Systems Containing Flammable or Combustible Liquids (5.2.4.7)

The required codes for these types of systems are listed in Pressure, Vacuum, and Cryogenic Systems: Flammable and Combustible Liquid Requirements [pdf].

Systems Containing Fluids with Health or Physical Hazards (5.2.4.8)

For requirements and codes, see Pressure, Vacuum, and Cryogenic Systems: Requirements for Systems Containing Fluids with Health or Physical Hazards [pdf].
