Paint mixing and storage areas.
Am Ind Hyg Assoc J 1984 May; 45(5):B7-B8
The problem of high concentrations of solvent vapors in paint mixing and storage rooms was addressed. According to the author, the vapors come from two major sources: evaporation during filling and pouring, and evaporation from paint containers, spills and leaks. The exposure of paint room personnel to organic solvent vapors can be minimized through the use of proper work practices and equipment that minimize solvent evaporation. It has been shown that close fitting drum covers with integral agitators and closable access doors are considerably more effective in preventing solvent evaporation than clamp on agitators and loose fitting lids. The authors suggest that: safety cans be used below solvent spigots to catch drippage and reduce evaporation; solvents should be pumped rather than poured and the height of free fall minimized; clean up of paint and solvent spills should be rapid; floors and work surfaces should be smooth for easy cleaning, and floor drains should be cleaned frequently to prevent pooling and should be made with a steep slope. The effectiveness of such measures was illustrated with measurements of solvents in a mixing room where some of the suggestions listed had been followed.
