Significance and Use4.1 This practice provides requirements for the handling,transportation, and storage of HFC-227ea encountered
10、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. Pr

15、s.5.2.1.1 Personnel who handle or store, or both, cylinders ofHFC-227ea shall be trained properly to recognize and identifythe characteristics of the product and the proper methods ofsafely handling full, partially full, and empty cylinders.5.2.2 All HFC-227ea transfers between storage containersand
16、 recycling processes shall be performed by personneltrained in handling procedures.5.2.3 HFC-227ea handling shall be in nonsmoking, heater-free, ventilated areas to preclude product accumulation. Provi-sions shall be made to ensure that service areas limit HFC-227ea concentrations do not exceed 10.5
17、 % for 1 min and0.1 % for 8 h.5.2.4 Cylinders shall not be overfilled. The liquid portion ofthe liquefied gases must not completely fill the containersinternal volume at any temperature up to and including 130F(54C). The maximum permitted filling density for pureHFC-227ea shall be 79 lb/ft3(1265 kg/

Unique coatings or preservatives applied prior toshipment to protect the containers are not considered contami-nation.5.3 Transportation:5.3.1
21、 Transportation shall be as specified in accordance withDOT regulations of Title 49 CFR.5.3.1.1 Shipment of materials between collectors, recyclers,and reclaimers should be within approved DOT guidelines forClass 2, Division 2.2, regulated materials. Any further provi-sions for special transportatio
22、n or packaging should be agreedupon between the collectors, recyclers, and reclaimers.5.3.1.2 The minimum design pressure requirements shall beas indicated in Title 49 CFR, Part 173.301.
