In response to a request from the U.S. Department of Justice, Federal Prison System, an evaluation was made of potentially hazardous conditions at the Federal Correctional Institution (SIC- 9999), La Tuna, Texas. Concern was expressed over employee/inmate exposures to isopropyl-alcohol (67630), toluene (108883), methylene- chloride (75092), nuisance particulate matter, wood dust, iron-oxide (1309371), and welding fumes from furniture refinishing. Furniture refinishing necessitated stripping, sanding, painting and general refurbishing. Airborne concentrations of isopropyl-alcohol ranged from 42 to 160 milligrams per cubic meter (mg/m3); respirable nuisance particulate matter, 0.4 to 1.6mg/m3; total nuisance particulate matter, 2 to 82mg/m3; and iron-oxide, below detection to 1mg/m3. The only evidence of a potential hazard was in the exposure to concentrations of total wood dust. The author concludes that a potential health hazard might exist to persons exposed to wood dust; the other exposures were not considered to be hazardous. The author recommends that efforts be made to reduce dust concentrations in sanding and grinding operations. A low volume, high velocity exhaust system is recommended which uses small volumes of air at high velocities to control dust from portable hand tools.
