HHE report no. HETA-86-251-1842, American Cyanamid, Michigan City, Indiana.
NIOSH 1987 Oct; :1-15
In response to a request from the International Chemical Workers Union, an evaluation was made of employee exposures to nickel (7440020) at the American Cyanamid Company (SIC-2819), Michigan City, Indiana, which produced petroleum industry catalysts. The workforce included 63 production workers and 33 administrative personnel. Employee exposures to metals and dusts, including 28 elements of toxicological importance, were evaluated during an industrial hygiene survey involving personal and general air sampling. Each of the 11 air samples showed aluminum (7429905), molybdenum (7439987), and nickel, while some showed calcium (7440702), cobalt (7440484), copper (7440508), iron (7439896), magnesium (7439954), and zinc (7440666). The only metal exceeding NIOSH Recommended Exposure Limit (REL) was nickel, ranging from below the American Conference of Governmental Industrial Hygienists threshold limit value of 10mg/m3 for nuisance dusts, ranging from these as nuisance dusts and further reduction in amounts should be made. The author recommends that care be taken to ensure good working order of mullers to prevent leaks. Generation of nickel dusts in impregnation area should be better controlled. A regular housekeeping schedule should be started for vacuum removal of accumulated dust from work areas. Appropriate respirators should be worn in muller room and impregnation and product load out areas.
