Significance and Use4.1 This practice provides requirements for the handling,transportation, and storage of HFC-227ea encounter
10、ed indistribution through both commercial and military channels. Itis intended to ensure that HFC-227ea is handled, transported,and stored in such a way that its physical property virtues arenot degraded. Transport may be by various means, such as, butnot limited to, highway, rail, water, and air.5.
11、 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, respectively.5.2 Handling:5.2.1 Handling shall be in accordance with CGA Publica-tion No. P-1, and a
12、s specified by the manufacturer.1This practice is under the jurisdiction of ASTM Committee D26 on Haloge-nated Organic Solvents and Fire Extinguishing Agents and is the direct responsi-bility of Subcommittee D26.09 on Fire Extinguishing Agents.Current edition approved June 1, 2005.
