Container leakage during storage

The initial sources of this contamination include leakage from storage tanks and buried containers, seepage from disposal and storage ponds, spills during transfer of materials, and mixing into ordinary trash of substances not considered hazardous at die time of use decades ago. 

Cultures, tissues, or specimens of body fluids are to be placed in a container that prevents leakage during collection, handling, processing, storage transport, transport, or shipping. 

The slow decomposition in storage of 98—100% formic acid with liberation of carbon monoxide led to rupture of the sealed glass containers. In absence of gas leakage, a full 2.5 1 bottle would develop a pressure of over 7 bar during 1 year at 25°C [1]. This has caused injury in laboratories. Formic acid is now often supplied in vented bottles, but unvented ones may still be met and should be vented by loosening the caps from time to time [5]. Explosive decomposition of formic acid on a clean nickel (1.1.0) surface was studied, using deuteroformic acid [2]. A full 1 1 bottle of 96%...

Containment of potential pollutants should ensure that no accidental releases to the environment occur under normal operational circumstances. However, if a minor leakage/spillage was to occur and go undetected for other than a short time scale, sufficient volume of pollutants could be lost to result in environmental deterioration equivalent to a major environmental accident. Typically, imdetected chronic leakage occurs in association with the storage of raw materials and wastes radier than during use, e.g., from pipework leading to and from storage.
