• Description:
  A local exhaust ventilation system designed to control exposure of furniture stripping workers to methylene-chloride (75092) fumes was described. A new ventilation system was developed by NIOSH researchers for a furniture stripping facility after it was found that the ventilation system installed by the owners of the facility decreased methylene-chloride levels from 2,160 parts per million (ppm) to 230ppm, which still exceeded the OSHA permissible exposure limit of 25ppm. The design and construction of a slotted hood ventilation system was described. After installation of the new system around the stripping area, air samples were evaluated for methylene-chloride, methanol (67561), toluene (108883), perchloroethylene (127184) and 1,1,1-trichloroethane (71556). No perchloroethylene was detected and 1,1,1-trichloroethane was not detected in 65% of the samples with the others containing no more than 5ppm. Breathing zone samples contained up to 25ppm methanol. Methylene-chloride levels during stripping and rinsing operations fell to 59ppm with the use of the new system and to 13ppm when only stripping operations were being performed. The installation of a local ventilation system in the rinsing area was recommended. [Description provided by NIOSH]
