For purposes of completeness, environmental evaluations of worker exposure to some of the other materials in the workplace such as asbestos (1332214), crystalline- silica (7631869), formaldehyde (50000), and asphalt (petroleum) were made. The methods for the evaluation of the work environment varied depending upon the substance being sampled. No medical investigation was made. Employees working in and around the shingle manufacturing line are not exposed to excessive levels of fibrous- glass. The slateman is exposed to potentially toxic levels of dust containing crystalline-silica. Employees entering the saturator are exposed to potentially high levels of benz(a)pyrene (50328). Employees' exposures to asphalt-fumes could not be adequately characterized to make a definite conclusion concerning toxicity with the currently available sampling and analytical techniques. Employees' exposures to formaldehyde, aromatic hydrocarbons, and total aliphatic hydrocarbons are not toxic.

The evaluation was requested by a company representative on behalf of two affected employees. The bulk abrasive grit sample contained less than 1 percent silicon-dioxide (7631869). Three of four respirable dust samples contained no silica and concentrations of respirable dust ranged from 3.4 to 4.7 milligrams per cubic meter (mg/m3), which were below the OSHA standard of 5.0mg/m3. No cadmium (7440439) was detected in any of the samples. Lead (7439921) concentrations ranged from 0.25 to 2.34mg/m3, exceeding the from 29.0 to 69.1 micrograms per cubic meter, exceeding the 10.0 micrograms per cubic meter OSHA standard. The author concludes that employees working at the abrasive blasting operation are potentially exposed to toxic airborne concentrations of inorganic lead and inorganic arsenic, and that employees may be exposed to excess concentrations of crystalline silica. A substitute grit should be considered, a medical monitoring program should be instituted, and a respiratory protection program should be provided for concerned employees.

The evaluation was requested by an authorized employer representative on behalf of 92 affected workers. Respirable dust and free silica concentrations generally were below the evaluation criteria of 10 milligrams per cubic meter (mg/m3) divided by the percentage of free silica plus 2, and 0.05mg/m3, respectively; 2 of 21 free silica and 4 of 21 respirable dust samples exceeded the standards. Concentrations of lead and carbon- monoxide (630080) were well below the exposure limits of 0.1mg/m3 and 35 parts per million, respectively. Workers reported respiratory tract symptoms, however these were attributed to contagious respiratory tract infections. The authors conclude that no hazardous exposures exist at this facility, but the dusts may aggravate inflamed respiratory tract mucous membranes. They recommend that properly fitted respirators be used and the housekeeping at the site should be improved.

Medical interviews were conducted with workers and ventilation systems were assessed. An unidentified individual requested the evaluation on behalf of about 400 production employees. All exposures were below environmental criteria and no job related illnesses were discovered. Ventilation was inadequate at the polishing wheels, dip tank, and chrome plating operation areas. They conclude that employees were not exposed to harmful concentrations of the tested chemicals at this facility. They recommend that proper ventilation be used, employee education regarding the use of respirators, written guidelines for respirator use, and the establishment of a materials safety data sheet file.

At the time of the survey the company employed about ten persons. There was one large production line which processed several tons of granular product or pesticide per day. Four or five workers were employed in the production of a liquid product identified as a seed protectant and nutrient mixture. Employees in the granular facility were exposed to concentrations of S-(((1,1-dimethylethyl)thio)methyl)-O,O-diethyl- phosphorodithioate in excess of the environmental criteria. Heptachlor (76448) exposures in the seed protectant area were also in excess of environmental criteria. Employees were exposed to excessive levels of aliphatic solvents, benzene (71432), captan (133062), diazinon (333415), and organophosphates. There was a potential exposure to free silica (7631869) in the granular facility. A significant number of workers reported acute symptoms probably due to excessive pesticide and dust exposures. The authors recommend that immediate action be taken to lower potential exposures by providing improved engineering controls and practices at this site. More frequent cleanup of the screening pit and other areas should be implemented until improved engineering controls can be tried. Strict contamination and decontamination control procedures, a program of employee and management education, a respiratory protection program, improvements in personal protective equipment use and care, improved medical and training practices, and discontinuance of the use of solvents containing benzene are also recommended.

The survey was requested by the employer on behalf of about 320 employees. Air samples were analyzed for total nuisance particles, respirable particles, and silica. No exposures exceeded the OSHA criteria of 5 milligrams per cubic meter for respirable or total nuisance particles, and no free silica was detected. High volume air samples detected silica as 23 percent of total dust and 16 percent of respirable dust, which exceed the OSHA criteria. The author concludes that a potential hazard exists from silica exposure and recommends that a medical and environmental monitoring program be established, the working environment be evaluated every 6 months, and a respirator use and care program be developed. Improved ventilation, housekeeping procedures, and worker protection practices also are recommended.

An unidentified source requested the evaluation to investigate the possible occurrence of silicosis among the workers. Nine cases of silicosis were identified through the medical evaluation. Other disorders included allergic rhinitis, chronic bronchitis, wheezing, repeated chest infections, and shortness of breath. Twenty-seven percent of the chest examinations were positive and pulmonary function tests were abnormal in 33 percent of the workers. Six additional cases of silicosis were identified by review of company records. The author concludes that a health hazard due to overexposure of free silica dust existed at this facility in the past and at the time of this evaluation. The current medical evaluation program for workers exposed to free silica is inadequate. An environmental and medical program should be established, including an industrial hygiene program, work safety practices, proper protective equipment, dust monitoring, preplacement and periodic medical examinations, and medical management of employees with suspected or diagnosed silicosis.

The plant is involved in treating and finishing steel produced in other facilities. The study was requested after sore throat complaints from workers in the HNX area where carbon-monoxide is oxidized to carbon-dioxide and removed using an MEA solution. MEA samples were collected on silica (7631869) gel. CO samples were collected using certified length of stain detector tubes. Employees were interviewed regarding work histories and health problems. Sixteen of 18 atmospheric samples of MEA were below the limits of detection by current techniques. The remaining two breathing zone samples of HNX operators were 2.1ppm and 1.0ppm. Such exposure might contribute to frequent sore throat complaints in employees. CO samples were below the recommended 8 hour time weighted average environmental limits. It was concluded that MEA exposure is a possible contributor to frequent sore throats among workers. Drying up standing MEA puddles, cleaning the substance from pipes and machinery, and reducing leakage were recommended.
