Workers were in the process of removing insulation from a boiler at the time four personal breathing zone samples were taken, extending over a period of about 0.5 hours. During the removal operation, one worker continually sprayed the boiler with water, thus minimizing the amount of dust generated by the other worker who was removing the insulation. Respirators were worn by these workers. Persons were engaged in this type of activity for only 4 to 8 hours per week. At no time were workers found to be exposed to levels of asbestos fiber which exceeded the Department of Labor allowable limit of 5 fibers/cubic centimeter (f/cc). No distinction was made between fibers of asbestos and glass (14808607). The concentrations for fibers of asbestos and glass together ranged from present at the site and encourages the continued use of both respirators and the wetting process when this activity is being performed.

(1973) Colorado Brick Company Boulder, Colorado. (Click to open report) Determination of respirable dust, free silica (7631869), lead (7439921), manganese (7439965), chromium (7440473), iron (7439896), and carbon-monoxide (630080) in 37 personal air samples taken at a brick manufacturing (SIC-3251) facility reveals that only respirable free silica exceeds the OSHA standard. Respirable samples taken at various working locations exceeded the federal standards, with the exception of the maintenance superintendent.

Noise is found to be above permissible exposure levels. Symptoms include burning or itching eyes, tiredness, heart palpitations, cough, weakness, dizziness, changes in skin color, interaction with alcohol, nervousness and headache.

Data are given for the toxic effects and standard concentration of the chemicals, and the respirable fractions for inert or nuisance dusts. Results indicate that the chemicals are not toxic and the nuisance dust levels not hazardous in the amounts used in the automotive company surveyed. Recommendations include installation of local exhaust ventilation, and dilute ventilation in specific areas, supply of fresh air to the toe-in pits in assembly lines, improved housekeeping, respirators for painters, provision of a maintenance program to control vapors, mists and gases, and environmental monitoring in areas where employees are significantly exposed to carbon-monoxide, including blood analysis for carboxyhemoglobin.

(Click to show more)Environmental samples for airborne silica containing dusts are collected at seven different job areas involved in making abrasive chips, 18 samples for total dust and 16 samples for respirable dust. The substances evaluated include aluminum-oxide (1344281), silicon carbide, iron-oxide (1332372), quartz (14808607), and tremolite (14567738), and the standard concentration is given for each substance. The physical agent evaluated, noise, has a standard level of 90 decibels. The silica (7631869) dust levels are found to exceed the Federal silica standard in the aluminum oxide separation area, inspection and boxing area, material handling area, special refracting area, and batch-mixing area. The tremolite concentrations exceed the standard in the batch mix area. No radiographic or other evidence is found for any serious respiratory problem from the dusts, although much dust is found accumulated in workers' nose at the end of the day. Recommendations include replacement of tremolite by a non-fibrous material; installation of a local exhaust system on the vibrating screens and hoppers, improved housekeeping, provision of respirators and ear protectors, periodic medical examination, and introduction of a hearing correction program.
