Epidemiologic notes and reports lead poisoning among bricklayers -- Washington State.
MMWR 1991 Mar; 40(10):169-171
The occurrence of symptomatic lead (7439921) poisoning among a work crew of bricklayers in Washington State was reported. Four workers of an 11 man crew developed lead poisoning while replacing the brick lining of an acid accumulation tank. A special brick mortar resistant to acidic environments, which contained 71% lead-oxide (1309600), was the source of exposure. Blood lead levels of the four contaminated workers ranged from 88 to 123 micrograms/deciliter. Three of the workers received chelation therapy with either oral penicillamine or intravenous calcium- ethylenediaminetetraacetic-acid. As a result of the lead poisoning outbreak, the employer initiated several worksite changes. These included improvements in safety training, the construction of a separate area for mixing mortar, shower facilities, and respiratory protection. Follow up investigations of the worksite revealed lack of air sampling and routine medical surveillance of lead exposed workers. These surveillance systems are essential in preventing excessive exposures to lead which may result in poisoning.
