Summary
A chemical delivery was directed to the wrong storage tank without checking the shipping papers. Mixing sodium hydrosulphide with ferrous sulphate generated toxic hydrogen sulphide, killing the driver. The bulletin stresses material identification, unloading procedures, personnel training and clear labelling, and suggests considering connections designed to hinder unloading mistakes.
