Re: [DCHAS-L] Art Studio
Contact me off the forum and I'll send you pictures of the ventilation that should be available for the brush cleaning and the SAA where the three containers for 1) solvent-based, 2) water-based, and 3) paint rags are kept for EH&S pick up from UMass-Amherst where they do this right.
Be aware, the solvents for painting are used at each easel. There is no way they can work in a fume hood, so there has to be
1) local exhaust for area solvents are dispenses and brushes are cleaned and these systems must provide which are part of the total exhaust for
2) the rapid dilution the room needs for the open solvent use. For a good solvent like Gamsol, that rate is 100 to 200 cfm/person depending on the location of the supply and exhaust relative to the breathing zone of the painters.
If you like I'll send you also the chapter on ventilation which has the formula for the dilution rate which depends on the TLV and evaporation rate of the solvent used.
All of the parameters for solvent exposure ventilation are in the ACGIH's Industrial Ventilation: A Manual of Recommended Practice. Be aware, you cannot set this up without a ventilation engineer to do the design, a rebalance the building's HVAC system, and a good EH&S department to handle the waste.
