Handling of hydrogen

Although it is widely recognized as a hazardous substance, large volumes of HF are safely manufactured, shipped, and used, and have been for many years. Excellent manuals describing equipment and procedures for the safe handling of hydrogen fluoride are available from manufacturers (16,17,42).

Storage and handling of hydrogen presents potential fire and explosion hazards. 

The editors emphasise the CAUTIONARY notes relating to the handling of hydrogen peroxide (p. 439), and to the distillation of extracts following the use of tetrahydrofuran/hydrogen peroxide in oxidation procedures (p. 552). 

An important issue with respect to handling of hydrogen is the safety of hydrogen storage, fueling, and transportation. Extensive safety assessments are necessary in order to have a sufficient basis for rules and regulations to be accepted by each country. For example, the maintenance of a hydrogen... 

For the safe handling of hydrogen fluoride, fluorine/helium. and trifluoromethyl hypo-fluorite the use of a specific apparatus has been proposed (Figure 1). 

To avoid handling of hydrogen cyanide directly, cyanohydrins have been employed as a source of HCN under reaction conditions. See, for example, a disclosure of this technique employing acetone cyanohydrin and either nickel, palladium, copper or cobalt catalysts W. C. Drinkard, Jr., U.S. Pat. 3,655,723 (1972) Chem. Abstr., 77, 4986p (1972).

Since anhydrous hydrogen fluoride serves as the reaction medium, special equipment is needed. An efficient fume hood is absolutely necessary. Care must be exercised in the handling of hydrogen fluoride to avoid injury to the operator.
