1、Designation: D6127 11Standard Practice forHandling, Transportation, and Storage of HFC-23(Trifluoromethane, CHF3)1This standard is issued under the fixed designation D6127; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year o
2、f last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This practice covers guidance and direction to suppliers,purchasers, and users in the handling, transportation, ands
3、torage of HFC-23.1.2 The values stated in inch-pound units are to be regardedas standard. The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.3 This standard does not purport to address all of thesafety conce
4、rns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

Significance and Use4.1 This practice provides requirements for the handling,transportation, and storage of HFC-23 encoun
11、tered in distribu-tion through both commercial and military channels. It isintended to ensure that HFC-23 is handled, transported, andstored in such a way its physical property values are notdegraded. Transport may be by various means, such as, but notlimited to, highway, rail, water, and air.1This

Practice5.1 To ensure safe handling, loading, unloading, storing,and transporting of material, personnel shall be trained in theCGA publications and Title 49 CFR regulations as listed in 2.2and 2.3,
16、respectively.5.2 Handling:5.2.1 Handling shall be in accordance with P-1.5.2.1.1 Personnel who handle or store, or both, cylinders ofHCFC Blend B shall be trained properly to recognize andidentify the characteristics of the product and the propermethods of safely handling full, partially full, and e
17、mptycylinders.5.2.2 All HFC-23 transfers between storage containers andrecycling processes shall be performed by personnel trained inhandling procedures.5.2.2.1 HFC-23 recycling and transfer processes shall be inconjunction with the equipment specified by the manufacturer.5.2.3 HFC-23 handling shall
18、 be in nonsmoking, heater-free,ventilated areas to preclude product accumulation. Provisionsshall be made to ensure that service areas limit HFC-23concentrations to not exceed 30 % for 1 min and 0.1 % for 8 h.5.2.4 Cylinders shall not be overfilled. The liquid portion ofHFC-23 must not completely fi
19、ll the containers internalvolume at any temperature up to and including 130F (54C).Filling density requirements are specified in Code of FederalRegulations (CFR) Title 49, Part 173 and Title 49 CFR,173.305.5.2.5 Handling of materials should be done in a manner thatprevents contamination or commingli
20、ng of halocarbons otherthan HFC-23.5.2.6 Cylinders shall be free of dirt and contamination thatwould contribute to or would cause deterioration of productduring shipment or storage. Precautions should be taken toprevent the entry of oil, water, or any other foreign matter intocontainers. Unique coat
