Documentation Requirements cont'd

DOE-HDBK-1101-96

to confirm that process equipment complies with recognized and generally accepted good

engineering practices. Some of the more frequently used codes and standards include the following.

American National Standards Institute (ANSI) establishes piping/valves/fittings/flanges and

equipment design criteria, including selection of materials and standards for engineering

drawings

American Society for Testing and Materials (ASTM) establishes standard testing methods

and acceptable test results, and definition of metallic and non-metallic material

National Fire Protection Association (NFPA) establishes electrical area classifications and

requirements, and fire protection design standards

American Society of Mechanical Engineers (ASME) establishes Boiler and Pressure Vessel

Code; welding materials and welder qualifications, NDT requirements, and standards; and

ferrous and non-ferrous material specifications

Institute of Electrical and Electronic Engineers (IEEE)/Instrument Society of America (ISA)

establishes design and application specifications for electrical and electronic equipment, and

failure rate data

The American Petroleum Institute (API) recommended practices govern the design of hydro-

carbon systems and facilities, including safety systems and process hazards management

guidelines for petrochemical facilities.

For existing equipment designed and constructed according to codes, standards, or practices that are

no longer in use, a determination must be made and documented that the equipment is designed,

maintained, inspected, tested, and operated in a safe manner. The following methods can be used to

demonstrate that the equipment is designed for safe operation.

Conduct engineering analyses or empirical testing to show that the equipment design

provides a level of protection equivalent to current codes or standards.

Change process parameters to comply with new codes or standards.

Use the PrHA to demonstrate that continued use of existing equipment does not significantly

increase the likelihood of catastrophic consequences, compared to equipment designed to

current standards [Q46].

Information about process chemical hazards must includethe following.

Toxicity information, such as LD50/LC50 values, Threshold Limit Values (TLVs)),

Immediately Dangerous to Life or Health (IDLH) values, and Emergency Response Planning

Guideline (ERPG) concentrations.

Permissible Exposure Limits (PELs).

Physical data, such as boiling point, freezing point, density, vapor pressure, vapor density,

solubility, evaporation rate, appearance, and odor.

Reactivity data, such as stability and compatibility with other families of materials including

acids, bases, and water.

Corrosivity data for containment vessels, metallics, and plastics.
