Title Mercury hazard and its control during operation of fluorescent tube breakers
Bibliographic information June 1972, Vol.33, No.6, p.419-422. Illus.
Abstract The use of commercial tube breakers to crush large numbers of fluorescent tubes for easier disposal was found to produce potentially hazardous mercury concentrations in the air surrounding the operator. These breakers consist of rotating hammers driven by a motor and mounted on a large steel drum equipped with a cloth dust-collecting bag. Each fluorescent tube contains 50mg of elemental mercury, and mercury vapour concentrations reached more than 1mg/m3 near the bag (more than 20 times the TLV). It is recommended that the dust collecting bag be replaced by an adequate local exhaust system, or that the tube breaker be located outdoors, away from occupied areas. Advice is also provided for the safe disposal of broken tubes.
