ASHRAE publishes Refrigeration Safety Standard
ASHRAE has published its 2004 refrigeration safety standard, which establishes procedures for operating equipment and systems to ensure the safety of the building occupants and technicians. ANSI/ASHRAE 15-2004 Safety Standard for Refrigeration Systems includes prohibition against the use of flammable refrigerants for applications for human comfort and clarifies the application of safety relief valves for pressure vessels. Standard 15 was first published in 1919 as a tentative code for the regulation of refrigerating machines and refrigerants in recognition of the need for enacting safety regulations.
