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

hydrocarbon 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 include the 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.
