Industrial hygiene survey report of Modern Home Insulation, Inc. in Dallas, Texas.
NIOSH 1978 Jun; :1-49
Worker exposure to airborne mineral fibers, total airborne particulate matter, respirable particulate matter, and trace metals were determined for insulators employed by Modern Home Insulation, Incorporated (SIC-3296), in Dallas, Texas, on April 28 and 29, 1977. No formal health or safety program was implemented at the facility. The peak exposure to fibers for the insulation installer in the truck was 0.035 fibers per cubic centimeter (f/cc), and 0.552f/cc for the insulation installer in the house. Peak total airborne particulate material was less than 0.01 milligrams per cubic meter (mg/m3) for the installer in the truck and 0.41mg/m3 for the installer in the house. Carbon-monoxide (630080) concentrations were below 10 parts per million (ppm) in and out of the truck and in the house. Concentrations were 10 to 20ppm in the attic with the blower running and 90ppm in the truck where the worker was emptying bags. The author concludes that the relatively high concentrations of total particulate material observed indicates the potential for respiratory irritation. Other potential hazards include heat stress during attic work and carbon-monoxide exposure while working in the insulation truck. The author recommends continued use of dust masks, attic ventilation, redirection of the exhaust discharge from the blower in the truck, and provisions for ventilation in the truck.
