1、 Tentative Interim Amendment NFPA55 Compressed Gases and Cryogenic Fluids Code 2016 Edition Reference: 1.1.1 TIA 16-1 (SC 15-12-3 / TIA Log #1195) Pursuant to Section 5 of the NFPA Regulations Governing the Development of NFPA Standards, the National Fire Protection Association has issued the follow
2、ing Tentative Interim Amendment to NFPA 55, Compressed Gases and Cryogenic Fluids Code, 2016 edition. The TIA was processed by the Technical Committee on Industrial and Medical Gases and was issued by the Standards Council on December 8, 2015, with an effective date of December 28, 2015. A Tentative
3、 Interim Amendment is tentative because it has not been processed through the entire standards-making procedures. It is interim because it is effective only between editions of the standard. A TIA automatically becomes a public input of the proponent for the next edition of the standard; as such, it
4、 then is subject to all of the procedures of the standards-making process. 1. Add new Appendix material for 1.1.1 to read as follows: 1.1.1* Applicability. This code shall apply to the installation, storage, use, and handling of compressed gases and cryogenic fluids in portable and stationary cylind
5、ers, containers, equipment, and tanks in all occupancies. A.1.1.1 The term “portable” points out the application of this code to systems other than those considered to be permanent; i.e., systems where the equipment is installed on foundations and meant to stay in place for a considerable period of
6、time. This code applies to portable and temporary systems, including the two types listed below: (1) Equipment that is ordinarily used for the transportation and delivery of compressed gases or cryogenic fluids but that is located at a customer (end user) location and used for storage of compressed
7、gases or cryogenic fluids. One example is a compressed gas tube trailer that is dropped at a customer location and left in place to supply the compressed gas to the customer use point. Another example is a cryogenic liquid trailer that is left at a customer location to supply cryogenic liquids to th
8、e customer use point (or vaporized into gas before going to the use point). (2) Equipment used for the temporary supply of compressed gases or cryogenic fluids at a customer location. An example is a portable cryogenic tank that is mounted on a trailer and dropped at the customer location and not al
9、ways connected to foundations by anchor bolts. Such a supply system may be in place for a matter of weeks as opposed to a more permanent system that is left in place for years. Some of the requirements of this code are not applicable to this type of equipment. For example, some sections of this code
10、 mandate that the equipment be anchored to permanent foundations. Equipment with wheels for transportation do not need to be anchored. However, auxiliary equipment, such as pressure reducing stations, would need to be anchored to a foundation. The user must determine which sections of the code apply
11、 to equipment and which sections do not apply. It is not the intent of this code to regulate transportation and delivery equipment when that equipment is used only to deliver product to a storage system at a customer location. For example, a cryogenic liquid trailer that delivers product into a stor
12、age system (and does not stay on site after delivering product) does not have to meet the requirements of this code. The trailer is governed by DOT/TC requirements. Another example is a compressed gas tube trailer that delivers product to a permanent storage system and does not stay on site to suppl
13、y product to the end user. Portable equipment is sometimes transported with product loaded in the storage vessel or may be shipped with the vessel empty, to be filled at the customer location. Equipment that is designed to be transported with product in it is governed by DOT/TC regulations. Nothing
14、in this code is intended to overrule the DOT/TC regulations governing the use of such equipment.
