Cylinders labeling

To prevent interchange of fittings between cylinders of combustible and non-combustible gases, the valve outlets are screwed left-hand and right-hand thread, respectively (Table 9.2). Primary identification is by means of labelling with the name and chemical formula on the shoulder of the cylinder. Secondary identification is by use of ground colours on the cylinder body. Unless specified in Table 9.2, gas and gas mixtures shall be identified by a colour classification indicating gas properties in accordance with the risk diamond on the cylinder label e.g. 

Figure 2, 3D comparison of the small SRP RNA domain. Models were constructed on a Silicon Graphics Indigo 2 Extreme workstation with the program ERNA-3D (S) with considerations as described in the text. Views of the small domains of the SRP RNAs of Methanococcus jannaschii (Met. jan.) and Homo sapiens (Horn, sap.) are shown with the sugar-phosphate backbones as narrow tubes and the base paired helical sections as cylinders. Labeling of the RNA ends, the helices, and the pseudoknot are precisely as in Figure 1. RNA sections of the M jannaschii model that correspond to nucleotides absent in the human model are shown dark-gray. (The PDB coordinates of the three-dimensional models are available from the SRP database at the internet address http //www.uthct.edu/SRPDB/SRPDB.html (2).)...

To illustrate, let s return to the gas cylinder with the movable or free-floating piston (see Figure 12.9). Assume that die cylinder labeled (a) contains a quantity of gas and the pressure on it is 1 atm. When the gas is heated, the molecules move faster, and their kinetic energy increases. This action should increase the number of collisions per unit of time and therefore increase the pressure. However, the increased internal pressure will cause the piston to rise to a level at which the internal and external pressures again equal 1 atm, as we see in cylinder (b). The net result is an increase in volume due to an increase in temperature. 

Before using silane, read all equipment instructions, cylinder labels, data sheets, and other associated information pertaining to silane and its use. 

Before using any mixture, read the cylinder label to determine that the cylinder contains the gas mixture desired. Also, read the MSDS on the mixture or mixture components, and become thoroughly familiar with the properties of the mixture before using it. Refer to the Methods of manufacture section for additional information on mixture properties, and to Chapter 2 for general safety guidelines. 

Non-flammable compressed gases do not catch fire easily or bum quickly. However, they possess other hazards. The cylinder label and SDS will tell you about the toxic properties and physical hazards. Ammonia, argon, carbon dioxide, nitrogen, oxygen, chlorine, and nitrous oxide are all non-flammable compressed gases. These gases may ... 

Appropriate care in the handling and storage of compressed gas cylinders is essential. This safety guide contains the basic measures necessary to use compressed gas cylinders safely. Additional information pertaining to each specific gas can be found in the cylinder labeling and in MSDS. 

The ICC classifies all three pentanes as flammable Hquids and requires that they be affixed with a red label for shipping. Because of their high vapor pressures, n- and isopentane are transported in heavy-walled dmms and neo-pentanes are transported in cylinders (see Packaging containers and INDUSTRIAL MATERIALS). 

Shipment and Storage. Liquid sulfur dioxide is commonly shipped in North America using 55- and 90-t tank cars, 20-ton tank tmcks, 1-ton cylinders, and 150-lb cylinders. Cylinders made of specified steel are affixed with the green label for nonflammable gases. The DOT classification is Poison Gas, Inhalation Ha2ard. Purchasers of tank-car quantities are required to have adequate storage faciUties for prompt transfer. 

Methyl bromide is sold both as the essentially pure compound, 99.5% minimum, with not more than 0.010% water and 0.001% acidity as HBr, and with small amounts of chloropicrin [76-06-2], CCI2NO2. During 1992 methyl bromide in tank cars was priced at 1.70/kg. Methyl bromide is suppHed in 37,850- and 60,560-L tank cars and in 12,220-L ISO cylinders. Repackagers supply methyl bromide in 0.45 kg or 0.68 kg cans for such appHcations as fumigating tobacco seed beds. Alone or in formulations, it is classified as a poison, class B, and requires a poison label. 

The measurement of oxygen diffusion is usually made by the use of as die labelling isotope. If a gas containing an initial concentration C, of in O , and Co is the initial conceiiuation of in a right cylinder oxide sample of thickness 21, and a is the ratio of oxygen atoms in the original gas phase compared widi that in the solid, dieii after a time t, when the concentration in the gas phase is C/... 

All cylinders must be properly labelled and colour coded (BS 349).

Following a standard notation[ 12,13], a cylindrical tubule can be described by the (L,M) couple of integers, as represented in Fig. 1. When the plane graphene sheet (Fig. 1) is rolled into a cylinder so that the equivalent points 0 and M of the graphene sheet are superimposed, a tubule labeled (L,M) is formed. L and M are the numbers of six membered rings separating 0 from L and L from M, respectively. Without loss of generality, it can be assumed that L>M.
