Abstract:
A fluid storage and dispensing vessel having associated therewith a colorimetric member that is effective to change color in exposure to leakage of a gas contained in the vessel. The colorimetric member may be constituted by a film, e.g., of a shrink-wrap character, that contains or is otherwise associated with a colorimetric agent undergoing color change in exposure to fluid leaking from the vessel. Such shrink-wrap film may be applied to a portion of the vessel susceptible to leakage, or alternatively to the entire vessel, so that the film is colorimetrically effective to indicate the occurrence of a leakage event by visually perceptible change of color.

Abstract:
A germane storage and dispensing system, in which germane gas is sorptively retained on an activated carbon sorbent medium in a vessel containing adsorbed and free germane gas. The activated carbon sorbent medium is deflagration-resistant in relation to the germane gas adsorbed thereon, i.e., under deflagration conditions of 65° C. and 650 torr, under which free germane gas undergoes deflagration, the activated carbon sorbent medium does not sustain deflagration of the adsorbed germane gas or thermally desorb the germane gas so that it undergoes subsequent deflagration. The deflagration-resistance of the activated carbon sorbent medium is promoted by pre-treatment of the sorbent material to remove extraneous sorbables therefrom and by maintaining the fill level of the sorbent medium in the gas storage and dispensing vessel at a substantial value, e.g., of at least 30%.
