Abstract
A walk through survey was made at the Ronald Alsip Furniture Refinishing (SIC-7641) facility located in Cincinnati, Ohio for the purpose of evaluating various control measures used to reduce exposure of employees to methylene-chloride (75092). This site was chosen for a survey because of the existing ventilation system on its Flow Over system and because it used a methylene-chloride based paint stripper. Paint was stripped by dipping the object in an open tank containing the stripper by spraying or brushing recycled stripper on the surface of the furniture in a large open tank, by a combination of these two methods, or by manual application. This company installed a 24 inch diameter wall fan on the floor under the flow over system. This was reasonable in that the methylene-chloride vapors were heavier than air. However, such a location would only be effective if the air velocity induced across the liquid surface is significantly higher than ambient room air currents. In this case the system was not effective and the workers were exposed to high levels of methylene-chloride; 618 and 85 parts per million for methylene-chloride and methanol (67561), respectively. The authors recommend that substitute stripping products be considered.
