Abstract
In response to a confidential request, an investigation was begun into reports of headaches and nausea in workers in the galvanizing department at UNR-Rohn Manufacturing (SIC-3479), Peoria, Illinois. The facility manufactured solid member hot dip galvanized towers and did customized galvanizing work. The company employed 51 workers in the galvanizing department. Personal breathing zone samples for zinc (7440666), cadmium (7440439), chromium (7440473), ammonia (7664417) and aluminum (7429905) all were well below the allowable limit. Samples for lead (7439921) ranged from trace to 56.1 micrograms/cubic meter (microg/m3) of air; the OSHA permissible exposure limit (PEL) was 50microg/m3. Surface wipe samples were collected and found to contain zinc at a range of 5.3 to 331mg/m2, lead from nondetectable to 16.3mg/m2, chromium ranging from nondetectable to 4.6mg/m2, and nondetectable for cadmium. The author concludes that workers were potentially exposed to lead levels in excess of the PEL. The author recommends that surface metal contamination levels should be kept at a minimum in areas such as the break area and rest rooms. Cadmium concentrations should be kept to the lowest feasible limit. Exposure monitoring should be continued, and improvements made in worker personal hygiene, and workplace cleanliness.
