In response to a request from an authorized representative of USWA Local Union No. 3405, an investigation was made into possible hazardous exposures to manganese (7439965) particulate and fugitive dust generated during grinding of manganese alloy and mild steel casings by grinder assemblers on the manganese floor at Abex Corporation, Pueblo, Colorado. Concern was also expressed over noise exposures and metallic oxides and gaseous air contaminants. The facility fabricated railroad trackwork including switch points, and various types of crossings and frogs. An environmental evaluation and a medical evaluation were conducted. The grinders were not found to be exposed to toxic concentrations of manganese or nuisance dusts at the time of the survey. Welders were not exposed to toxic concentrations of manganese or vanadium (7440622) fumes, ozone (10028156), nitrogen-dioxide (10102440) or iron-oxide (1332372) fumes. The authors conclude that the workers were not exposed to toxic concentrations of these substances under the conditions studied. The authors recommend that environmental control, manganese screening, and a respiratory protection program be used at this facility.
