Question: How can my company distinguish and understand the differences between 1) "Codes/Standards”, 2) "Rules & Guidelines” and 3) "Regulations & Directives”, as they relate to Oxygen Systems?
Answer:
  1. Codes & Standards: These are Consensus Safety Documents developed by non-profit trade associations, professional societies or standards-making and testing bodies that serve industrial, commercial and public needs. (They are empowered to include advisory and mandatory provisions, which may be adopted by authorized regulatory agencies, i.e.; NFPA, CGA, ASTM, ASME, etc.)
  2. Rules & Guidelines: These are the technical information and safe practices and procedures developed by organizations (or groups representing such organizations) for their own needs i.e.; NASA, Los Alamos National Laboratory.
  3. Regulations & Directives: These are used by official bodies, authorized to create safety requirements – enforceable by political jurisdiction. These Regulations are Mandatory and are contained in the Code of Federal Regulations (CFR) i.e., OSHA, DOT, U.S. Coast Guard, etc.
  4. Additional – Oxygen Safety Related Standards: Numerous groups, societies and associations are responsible for monitoring Oxygen Safety Standards; they and their number of Oxygen Related Standards are as follows:
  • American National Standards Institute (ANSI) – 9 standards
  • American Petroleum Institute (API) – 1 standard
  • American Society of Mechanical Engineers (ASME) – 3 standards
  • American Society for Testing and Materials (ASTM) – 22 standards
  • Compressed Gas Association (CGA) – 16 standards
  • Federal Government – 16 standards
  • National Fire Protection Association (NFPA) – 8 standards
  • Society of Automotive Engineers (SAE) – 34 standards
  • Insuring Associations
  • Professional Societies
  • Technical Trade Groups
  • Testing Standards and Safety Groups

Question: Can my Oxygen System be "Certified”?
Answer: ASTM's "Glossary of Terms' defines ‘CERTIFICATION' as "the process that results in the documented status, that qualifies a vessel or system to operate in the service for which it is intended” (or qualifies operating personnel for specific duties). Also refers to the document itself.
NOTE: GTC certifies all Oxygen Piping systems which it provides. GTC can also assist with "Certification or Recertification” of existing Oxygen Systems.
Question:Does my existing Oxygen System require "Recertification”?
Answer: ASTM's "Glossary of Terms” defines ‘RECERTIFICATION' as "The procedure by which a previously certified vessel or system, by appropriate tests, inspections, examinations and documentation, is qualified to continue or be returned to operations at the designed pressure.
