The management of the Silver Deer Spectrum (SIC-3229), Boulder, Colorado, requested an evaluation of exposures to lead (7439921), glues and solvents for workers involved in the grinding, polishing, gluing and silkscreening of leaded glass crystal art objects. Sixteen breathing zone and general room air samples were collected with lead concentrations ranging from not detectable to 0.08mg/m3. Three of these readings exceeded the evaluation criteria of action level for lead. Methylene-chloride (75092) was found in small quantities in 13 of 14 air samples. The highest level of methylene-chloride detected was 15.7mg/m3. No workers from the grinding room showed blood lead levels above 40 micrograms/deciliter. No evidence of lead toxicity was noted in workers from the blood samples or from discussions held with the workers. The author concludes that a potential health hazard from lead existed at the time of the evaluation. The author recommends that care be taken to reduce lead exposure in the grinding room. No dry grinding or polishing of the leaded glass should be permitted. The down draft ventilation in the grinding stations should be maintained, cleaned, and balanced so that each work station has sufficient capture velocity.
