Significance and Use
16、4.1 This practice provides requirements for the handling, transportation, and storage of Halon 1211 encountered in distributionthrough both commercial and military channels. It is intended to ensure that Halon 1211 is handled, transported, and stored in sucha way that its physical property values ar
17、e not degraded. Transport may be by various means, such as, but not limited to, highway,rail, water, and air.5. Practice5.1 To ensure safe handling, loading, storing, and transporting of material, personnel shall be trained in the CGA publications,CFR regulations, and other documents, as listed in S
18、ections 2.2 and 2.3, respectively.5.2 Handling:5.2.1 Handling shall be in accordance with CGA Publication P-1 Standard for Safe Handling of Compressed Gases inContainers.Containers and as specified by the manufacturer.5.2.1.1 Personnel who handle or store, or both, cylinders of Halon 1211 shall be t
19、rained properly to recognize and identify thecharacteristics of the product and the proper methods of safely handling full, partly full, and empty cylinders.5.2.2 All Halon transfers between storage containers and recycling processes shall be performed by personnel trained inhandling procedures.5.2.
20、3 Halon 1211 recycling and transfer processes shall be in conjunction with the equipment requirements specified by themanufacturer.5.2.4 Halon 1211 handling shall be in nonsmoking, heater-free, ventilated areas to preclude product accumulation. Provisionsshall be made to ensure that service areas li
21、mit Halon 1211 concentrations to not exceed 1 % by volume for 1 min and 0.01 %by volume for a time weighted exposure of 8 h.5.2.5 Cylinders shall not be over filled. The liquid portion of the liquefied gas shall not completely fill the containerscontainersinternal volume and the pressure shall not e
22、xceed five fourths the service pressure of the container at any temperature up to andincluding 130F (54C). The maximum permitted filling density for Type I product 130 F (54 C). To prevent excessive pressurein accordance with Specification D7673D7673/D7673M shall be 100 lb/ft3, the fill density of T
23、ype 1 product within a containershould not exceed that needed to achieve complete filling of the container at the maximum envisaged storage temperature. Forexample, for a U.S. DOT 4BW260 cylinder, the nitrogen partial pressure shall not exceed 129 psig at 70 F (9.9 bar at 21 C) fora 100 lb/ft3 (1602
24、 kg/m3).kg/m3) fill density, which yields a total pressure of 150 psig at 70 F (11.4 bar at 21 C). For this example,the safe working pressure of the 4BW260 cylinder is not exceeded for temperatures below 131 F (55 C). Filling densityrequirements for Type II product (pure specification) are specified
25、 in CFR Title 49, Part 173.304 and CFR Title 49, Part 173.305.(See Figs. 1 and 2.)5.2.6 Handling of materials should be done in a manner that prevents contamination or commingling of materials other thanHalon 1211.FIG. 1 Vapor Pressure of Halon 1211 versus TemperaturePressure versus Temperature, Eng
26、lish UnitsD7815 1725.2.7 Cylinders shall be free of dirt and contamination that would contribute to or would cause deterioration of the productduring shipment or storage. Precautions should be taken to prevent the entry of oil, water, or any other foreign matter into thecontainer. Unique coatings or
27、 preservatives applied prior to shipment to protect the containers are not considered contamination.5.3 Transportation:5.3.1 Transportation shall be as specified in accordance with DOT regulations of CFR Title 49 .49.5.3.1.1 Shipment of materials between distributors, collectors, recyclers, and recl
28、aimers should be within approved DOTguidelines for Class 2.2, regulated materials.Any further provisions for special transportation or packaging should be agreed uponbetween the collectors, recyclers, and reclaimers.5.3.1.2 The minimum design pressure requirements shall be as stated in CFR Title 49,
29、 Part 173.304. The pressure inside thecontainer at 70F (21C)70 F (21 C) shall not exceed the service pressure for which the container is marked. The pressure insidethe container at 130F (54C)130 F (54 C) shall not exceed five fourths the service pressure for which the container is marked.Fig. 1Figs.

31、oughout the entire transport route.5.3.2.1 If cylinders are likely to be subject to unacceptable transport conditions, the cylinders should be placed under insulatedconditions.5.3.3 Compressed gas cylinder permanent marking requirements shall be in accordance with CFR Title 49, Part 178 and mustbe m
32、aintained in legible condition as required by CFR Title 49, Part 173. Warning labels shall be affixed to the cylindersconforming to the requirements of CFR Title 40, Part 82.106.82.106 shall be affixed to the cylinders.5.3.4 Containers used for shipping of Halon 1211 conforming to Specification D767
