Health hazard evaluation determination report: HHE-77-15-421, Leed and Northrup Corporation, Expendable Devices Division, Ellwood City, Pennsylvania.
NIOSH 1977 Sep; :1-25
A Health Hazard Evaluation investigation was conducted by NIOSH on December 13-15 at the Leed and Northrup Corporation, Expendable Devices Division, Ellwood City, Pa., a facility engaged in the manufacture of carbon analysis and temperature determination devices (SIC-2865). The survey was prompted by a request from an authorized representative of the approximately 20 affected employees to determine whether any substance found in the work place has potentially toxic effects in such concentrations as used or found. The airborne concentrations of formaldehyde (50000) and ammonia (7429905) were low enough to prevent respiratory injury but not the subjective upper eye and respiratory irritation reported by some of the workers. Workers involved in cement mixing presented dermatitis which could be minimized by use of protective equipment and other measures. The operator of a large mixed was exposed to potentially toxic levels of respirable crystalline silica (7631869). Recommendations are made for measures that can help minimize dermal and respiratory effects apparent to the manufacturing processes evaluated.
