Year Published and Title
(1975) Ingersoll Rand Foundry Division, Athens, Pennsylvania. (Click to open report)
Personal and environmental sampling of a foundry (SIC-3339) reveals that employees performing sand mulling, pouring and shakeout operations are exposed to potentially toxic concentrations of crystalline silica (quartz) (1317799) which can cause silicosis. In addition, excessive noise levels are noted and excessive levels of methane (74828) present an explosive gas hazard. Recommendations are presented for the control of silica (7631869) dust, including maintenance of ventilation systems, local e... (Click to show more)
(1975) McCall Printing Company, Dayton, Ohio. (Click to open report)
Health hazard evaluation in a printing company shows that trichloroethylene (79016) is not toxic in the amounts used in paper splicing operations but that paper dust exposures create mild irritation in employees with allergic disorders. Exposures to "press oven smoke" result in episodes of minor, transient, irritative symptoms. Safety recommendations include installation of local exhaust ventilation at press slitter knives, and sweeping of settled dust on catwalks into refuse containers for redu... (Click to show more)
(1975) Owens-Illinois Glass Company, Atlanta, Georgia. (Click to open report)
Environmental evaluation of a glass manufacturing company (SIC-3231) reveals that airborne dusts containing free silica (7631869) in batch houses are not toxic at the concentrations found. A potential hazard from silica dust exists to maintenance men servicing the batch house equipment. Measures for the control of free silica dust are presented.
(1975) Pacific Grinding Wheel Company, Marysville, Washington. (Click to open report)
Resinoid mixing department workers are found to be experiencing toxic effects of an irritant nature from exposure to excessive levels of furfural (98011) used in the formulation of grinding wheels. Lead, fluoride, phenol (108952), total dust, and silica (7631869) dusts are cited as not toxic as used or in the concentrations found.
(1975) Philadelphia Quartz Company, Chester, Pennsylvania. (Click to open report)
Respirable dust air samples in a quartz (14808607) company are collected in the breathing zone of three employees and in two general locations. Respirable dust concentrations are found to range from 0.1 to 1.4 milligrams per cubic meter. Employees working in areas of maximal Q-cel dust or ammonia (7664417) gas, are found to have eye burning, tearing or irritation of the upper respiratory system due to exposure to ammonia. Eye burning and nasal stuffiness occur from excessive dust exposures, symp... (Click to show more)
(1975) Ranco Controls, Division of Ranco Inc., Worthington, Ohio. (Click to open report)
A high percentage of workers in the initial electric control assembly and inspection department are found to have periodically experienced cutaneous irritation from occupational exposure to fibrous glass. Measured concentrations of airborne particulates were found to be well below existing standards for fibrous glass dust on the day of measurement.
(1975) Raven Industries, Inc., Sioux Falls, South Dakota. (Click to open report)
Employee exposures to fibrous glass, acetone (67641) and styrene (100425) vapor are not found toxic in the amounts detected in a factory manufacturing fibrous glass containers, but a potential for employees to be overexposed to styrene vapor is found to exist in the spin cast molding area. Recommendations include improvement of ventilation system, usage of NIOSH approved respirators and filters in the chopping, hand molding, and fiber glass sanding areas, and a follow up industrial hygiene surve...

(1975) Schulmerich Carillons, Inc., Sellersville, Pennsylvania. (Click to open report)
Biologic sampling of employee's hair, blood, and urine, and air measurements of copper (7440508), tin (7439921), and lead (7440315) dusts in a plant manufacturing musical bells indicate that exposure to bronze dust is nontoxic. Discoloration of one employee's hair is due to interaction of lipids on the scalp and hair with the bronze dust and is only of cosmetic significance.
(1975) United Airlines Corporation, San Francisco, California. (Click to open report)
An airlines reservations office (SIC-4583) was studied by NIOSH to evaluate employee exposures to dust, radiation from cathode ray tubes, carbon-monoxide (630080), and aldehydes. Carbon-monoxide and aldehyde levels were measured with detector tubes, temperature and relative humidity were checked, ventilation measurements were made, total dust levels were monitored, and the television monitors were checked for radiation leakage. Medical questionnaires were administered and reviewed by NIOSH medic... (Click to show more)
(1975) Westvaco Corporation Carbon Plant, Chemical Division, Covington, Virginia. (Click to open report)
An evaluation was made to determine whether exposure to carbon (7440440) dust and carbon impregnated with phosphoric-acid (7664382) was posing a health hazard to the employees in paper mills (SIC- 2621). This facility consists of three divisions: 1) paperboard, 2) carbon and 3) research. The area of interest during this evaluation was the carbon division. Two types of carbon are made at this facility: one from ground wood pulp and the second from bituminous coal. The evaluation consisted of an e... (Click to show more)
