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.

16、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 emptycylinders

17、.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 be in nonsmo

18、king, 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 fill the contai

19、ners 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 commingling of halocar

25、should be stored in areas that will protectvessels form physical and environmental damage, and tamper-ing from unauthorized personnel.5.4.2.1 Facilities should be of construction and orientationso that safety requirements are fulfilled for storage of pressur-ized cylinders.5.4.3 Storage cylinders sh

26、all be fitted with pressure releasemechanisms to limit vessel pressure to not more than the ratedworking pressure of the container in use at any particular time.5.4.3.1 Periodic hydrostatic testing and re-inspection ofcylinders used for HFC-23 shall comply with Part 180 of Title49 CFR.5.4.4 Containe

27、rs shall be clearly marked and labeled toidentify whether the HFC-23 contained conforms to Specifi-cation D6126/D6126M.5.4.5 Insulation shall be placed on pallets or shoring andprovisions should be made to prevent excessive shock orthermal fluctuations to cylinders.5.4.6 Cylinders shall be stored in

28、 a manner that will preventcontamination from external sources.6.
