Compressed gas safety

The AP600 passive safety systems use natural forces gravity, natural circulation, and compressed gas. Simple, mostly fail-safe, s alves align the passive safety systems upon...

Conclusively, hydrogen has been used and stored safely in the industry for quite a long time as compressed gas or liquefied hydrogen, and it seems that metal hydride storage will be equally safe or even safer. Consideration of future hydrogen applications reveals no safety problems in the industrial and commercial markets. Although hydrogen safety... 

The colors purple, brown, black, and gray have not been assigned a safety connotation. Specific color codes are also employed in the identification of alarms panel indicators, piping, compressed gas cylinders, electrical wiring, fire sprinkler temperature ratings, etc. Although these sometimes do not correspond with similar meanings. 

The sources of acetylene, nitrous oxide, and sometimes air are usually steel cylinders of the compressed gases purchased from specialty gas or welders gas suppliers. Thus, several compressed gas cylinders are usually found next to atomic absorption instrumentation and the analyst becomes involved in replacing empty cylinders with full ones periodically. Safety issues relating to storage, transportation, and use of these cylinders will be addressed in Section 9.3.7. The acetylene required for atomic absorption is a purer grade of acetylene than that which welders use. 

Compressed gas and liquid storage are the most commercially viable options today, but completely cost-effective storage systems have yet to be developed. The safety aspects with all storage options, particularly the novel hydride storage options, must not be underestimated (Schlapbach and Ziittel, 2001). 

Since salt caverns contain brine and other contaminants, the type of gas to be stored should not be sensitive to the presence of contaminants. If the gas is determined suitable for cavern storage, then cavern storage may not offer only economic benefits and enhanced safety and security salt caverns also offer relatively high rates of deliverability compared to reservoir and aquifer storage fields. Solution-mined gas storage caverns in salt formations operate as uncompensated storage—no fluid is injected into the well to displace the compressed gas.

The Compressed Gas Association (CGA) is composed of members from firms that produce and distribute compressed, liquefied, and cryogenic gases. The association develops and publishes recommendations to improve safety concerning the transportation, storing, and handling of gases. The CGA provides handbooks, technical publications, videotapes, and posters relating to safety. 

The first level of safety for quality and control is the construction of compressed gas cylinders. The specifications for their construction in North America is defined by Department of Transportation (DOT) and Canadian Transport Commission (CTC) regulations. Cylinders are made from carbon steel or alloy steel with seamless, brazed, or welded tubing that is formed by billeting (drawing flat... 

Sections of a compressed gas tank are designed to provide safety for potentially abusive conditions. The most common structural protection is the tank cap, which is placed over the valve, then screwed onto the threaded neck of the compressed gas tank (see Fig. 5.2). In addition, you can obtain separate foot-rings that help a cylinder stand up, along with protective girdles for around the valve area. 

Figure 11.22 on the next page shows a typical compressed gas cylinder. You can see that it is built to withstand high pressures. There are other safety precautions as well, however. 

Caution Sulfur dioxide gas is intensely irritating to the eyes, throat, and upper respiratory system. Liquid sulfur dioxide may cause skin burns, which result from the freezing effect of the liquid on tissue. Safety precautions to be observed in handling the material are specified in Pamphlet G-3 published by the Compressed Gas Association, 4221 Walney Road, Fifth Floor, Chantilly, VA 20151-2923.
