Laboratory equipment safe handling

Beryllia materials are fabricated in much the same way as alumina compounds, although the toxic properties of the powders mandate that they be processed in laboratories equipped to handle them safely. 

Safe handling practices are essential at all stages of production, from the laboratory to the manufacturing operations. The safety committee should inspect and advise on processing equipment and be responsible for providing personal protection, eye wash fountains, safety showers, etc. 

The publisher cannot assume any legal responsibility for given data, especially as far as directions for the use and the handling of chemicals and biological material are concerned. This information can be obtained from the instructions on safe laboratory practice and from the manufacturers of chemicals and laboratory equipment. 

Extensive experience has been gained in the safe handling of liquid hydrogen, both in physics laboratories and, on a tonnage scale, for use in the space industry as a rocket fuel. No insuperable technical problems are encountered. The specialized equipment is, however, very costly and is one reason why liquid hydrogen has not been seriously considered as a fuel outside the space industry, where its low density is a particularly valuable property. Experimentally, liquid hydrogen has been employed as a fuel in automotive applications and there has been some preliminary consideration of using it as an aircraft fuel see Section 7.3, Chapter 7. 

Proper use of laboratory equipment is required to work safely with hazardous chemicals. Maintenance and regular inspection of laboratory equipment are an essential part of this activity. Many of the accidents that occur in the laboratory can be attributed to improper use or maintenance of laboratory equipment. This chapter discusses prudent practices for handling the apparatus often used in laboratories. 

Wedum, in a review of the handling of infectious agents, outlined the procedures to reduce the hazard but concluded that the safe handling of infectious agents depended more on the attitude of the laboratory director and his or her senior assistants than on equipment. He stressed the importance of education, engineering and enforcement to protect the experiment, the scientist and the administrator. 

The major characteristic of technetium is that it is the only element within the 29 transition metal-to-nonmetal elements that is artificially produced as a uranium-fission product in nuclear power plants. It is also the tightest (in atomic weight) of all elements with no stable isotopes. Since all of technetiums isotopes emit harmful radiation, they are stored for some time before being processed by solvent extraction and ion-exchange techniques. The two long-lived radioactive isotopes, Tc-98 and Tc-99, are relatively safe to handle in a well-equipped laboratory. 

Especially thanks to these efforts, SC CO2 can be handled safely in high-pressure equipment from the laboratory- to the industrial scale. Nevertheless, its limited power to dissolve polar or non-volatile compounds represents a major drawback in most of these applications, particularly in the garment-cleaning process, where the design of CCVphilic...
