Título Accidental mixing of incompatible chemicals, followed by multiple fatalities, during a bulk delivery
Información bibliográfica National Transportation Safety Board, Washington, D.C. 20591, USA, 26 Aug. 1971. 9p. (Available from National Technical Information Service, Springfield, VA 22151, USA. Accession No.PB.203402).
Resumen During the transfer of bulk liquid sodium hydrosulfide from a tank truck to a tannery storage tank, the transfer hose was erroneously connected to an open vat containing a tanning liquor. Hydrogen sulfide was released when the chemicals reacted, and 12 tannery workers were overcome by the toxic gas; 6 died as a result of the accident. The investigation pointed to a failure in communications between the truck driver and the tannery foreman, to a lack of instructions, and to the need for adequate labelling in order to ensure clear identification of the chemicals involved by all parties concerned.
