Title A case history report: An investigation into the safe handling of acid carboys and drums.
Bibliographic information Mar. 1977, Vol.14, No.3, p.6-10. Illus.
Abstract Description of 2 accidents due to the bursting of steel drums containing sulphuric acid (one in a metal cleaning room and a case on the mid deck of a ship). The article discusses events leading up to the incidents: leaving the drums in hot sun or overheated rooms, causing internal pressure build-up; rolling, trucking and handling, causing the acid to wash iron sulphate off the drum lining and expose new steel surface for the acid to attack, releasing additional hydrogen gas, with consequent pressure increase; insufficient ullage (space left in drum to allow for gas expansion; the ullage space necessary as the temperature increases is shown graphically); failure to vent drums regularly; no attention paid to the fact that the drums were obviously bulging. Preventive measures are indicated, and the article considers problems of contamination, corrosion, leakage, explosions and bursting; safe working methods: venting, drums not to be stored in the open exposed to weather, storage in upright position, labelling and marking, personal protective equipment, inspection, draining, cleaning and disposal of drums.
