Cal. Code Regs. Tit. 8, § 500 - Approval of Devices
(a)
All devices which are used in anhydrous ammonia service shall be of a type and
construction suitable for the use to which they are put. They shall preferably
be listed by at least one nationally recognized testing laboratory such as, but
not limited to, Underwriters Laboratories, Inc. and Factory Mutual Engineering
Corp. (For the purposes of this paragraph, the word "listed" means that
equipment is of a kind mentioned in a list which is published by a nationally
recognized laboratory which makes periodic inspection of the production of such
equipment, and states such equipment meets nationally recognized standards or
has been tested and found safe for use in a specified manner.)
The Division may approve or accept devices upon satisfactory evidence that they are designed and constructed for safe operation in anhydrous ammonia service.
Drawings and calculations for custom-built devices must be submitted to the Division for acceptance. Both the drawings and calculations must be signed by a registered professional engineer.
