Many chemicals are often incompatible and fall into such categories as flammable materials combustible products water reactive and unstable compressed gases pyrophoric cryogenic corrosive explosive and toxic. Safe management practices require attention be given to special handling and storing of these materials as well as proper disposal. This chapter focuses on safe handling practices for common laboratory environments. Examples of specific chemicals and proper handling practices are reviewed and specific recommendations for a number of common chemicals encountered in laboratories are provided. The Web sites noted in the last chapter are a good source for obtaining the MSDSs of many of the chemicals discussed in this chapter. COMPRESSED AND LIQUEFIED GASES Compressed and liquefied gases should be used and handled only by properly trained personnel. Some of the most widely used gases in a laboratory are acetylene hydrogen methane propane carbon monoxide and natural gas. This section describes the hazardous properties of these gases and provides recommendations for gas storage and handling. Table 1 provides some properties of common flammable gases. Other sources of information on gases include MSDSs the Matheson Gas Data Book Compressed Gas Association pamphlets such as C-6 Standards for Visual Inspection of Steel Compressed Gas Cylinders and C-8 Standard for Re-qualification of DOT-311t Seamless Steel 381 Copyright 2001 Marcel Dekker Inc. 382 CHAPTER 7 Cylinders and NFPA publications. The MSDSs and the Matheson Gas Data Book deal chiefly with properties and use of gases and components of gas systems pamphlets from the Compressed Gas Association deal with standards and requirements of the Department of Transportation. The NFPA National Fuel Gas Code describes appropriate containers and .
