The Safety Characteristics of LaNi5 Hydrides,
Abstract
Experimental studies have been conducted to determine the limits of safety in handling, shipping, and usage of LaNi hydride. Emphasis has been given to the accident-oriented safety problems such as punctured containers, impact, explosion, shock, and external fire. Various aspects of hazards have been evaluated for bulk powders; the ignition temperature, the relative combustibility, flammability, shock sensitivity, impact sensitivity, electrostatic spark sensitivity and potential explosibility. Since the LaNi5 hydrides break down to powders after repeated absorption and desorption of hydrogen, the ultimate interest in the safety considarations is with fine powders. A characterization study of the particles and particle size was included as part of the study. ANother independent study was also made of the safety of dust clouds of LaNi5 hydrides. The ignition sensitivity and explosion severity were determined, and an index of explosibility of dust clouds was established.
