Significance and Use4.1 This practice provides requirements for the handling, transportation, and
10、 storage of IG-100 encountered in distributionthrough both commercial and military channels. It is intended to ensure that IG-100 is handled, transported, and stored in such away that its physical property virtues are not degraded. Transport may be by various means, such as, but not limited to, high

Practice5.1 To ensure safe handling, loading, unloading, storing, and transporting of material, personnel shall be trained in CGAStandards C-1, C-4, C-6, C-7, and P-1, and CFR Title 49, Part 172, CFR Partthe CGA publications and CFR regulations as listedin Sections 2.1 17
16、2, Part 172.101 CFR Title 49, Part 173, CFR Title 49, Part 178, and 2.2CFR Title 49, Part 180., respectively.5.2 Handling:5.2.1 Handling shall be in accordance with CGA P-1.5.2.1.1 Personnel who handle or store, or both, cylinders of IG-100 shall be trained properly to recognize and identify thechar
17、acteristics of the product and the proper methods of safely handling full, partially full, and empty cylinders.5.2.2 Facility personnel must be trained in applicable standards CFR Title 49, Part 173 and CFR Title 49, Part 178, and CGAStandards C-1, C-4, C-6, C-7, and P-1.5.2.2 IG-100 handling shall
18、be in nonsmoking, heater-free, ventilated areas to preclude product accumulation. Provisions shallbe made to ensure that service areas limit IG-100 concentrations to not exceed 52 % (10 % Sea Level Oxygen equivalency) for30 s and 7 % (19.5 % Sea Level Oxygen equivalency) for 8 h.5.2.3 Cylinders shal
19、l not be overfilled. Filling density requirements are specified in CFR Title 49, Part 173 (173.302).5.2.4 Cylinders shall be free of dirt and contamination that would contribute to or would cause deterioration of product duringshipment or storage. Precautions should be taken to prevent the entry of
20、oil, water, or any other foreign matter into containers.Unique coatings or 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 .5.3.1.1 The

The pressure inside thecontainer at 70F (21C) shall not exceed the service pressure for which the container is marked. The pressure inside the containerat 130F (54C) shall not exceed 5/4 times the service press
22、ure for which the container is marked. Fig. 1 and Fig. 2 illustrate theeffect of temperature on cylinders filled with IG-100.5.3.2 Transportation shall be by suitable vehicles to preclude cylinder damage by excessive mechanical vibration, shock,freezing, or deleterious high temperatures throughout t
23、he entire transport route.5.3.2.1 If cylinders are expected to be subjected to unacceptable transport conditions, the cylinders should be placed underinsulated conditions.5.3.3 Compressed gas cylinder permanent marking requirements shall be as specified under CFR Title 49 Part 178 and must bemaintai
