TG No. 144 August 1987

(4) The physical parameters and evaluation methodology for spray
booths or spray rooms are discussed In Appendix D. Based on these physical
parameters and sampling results, recommendations concerning the operation of
an individual booth can be made.

c. Inadequate ventilation (when compared with the requirements shown in
Appendix E) will not require upgrade unless an exposure exceeding the
appropriate standard has been documented. Therefore sam ling data is critical
.P
to documenting the hazard potential of a painting operation.

d. When an upgrade Is required or a new booth is being designed, the
physical parameters provided In the references listed In paragraph 2-2a must
be incorporated into the design.

e. Solvents encountered may be methyl eth I ketone (MEK), xylone,
toluene, ethyl acetate, and others. The MSDS @or all materials used must be
consulted (see para 4-1).

f. Paints and primers which contain less toxic materials may be
available. Whenever possible, Type II or III aliphatic PUP should be
substituted for MIL-C-46168 Type I since they are lead and chromate free.
Non-lead-containing primers should be used when available (see App C. para
C-15).

2-3. BRUSH OR ROLLER PAINTING (recognition). Brush or roller painting does
not cause significant aerosolization of paint or primer constituents, and
ur. However, solvent
concentrations are present in the air from vaporization. Solvent emissions
from brush or roller painting will be less than spray painting since the
materials are applied without additional thinning and usually less
paint/solvent is used. Solvent exposures would be expected only in very
confined spaces.

2-4. INDOOR OR OUTDOOR BRUSH AND ROLLER PAINTING (et,almatio,. a,.d control).
PPE and respiratory protection requirements are determined by the quantity of
material being used and the location of the operation. For example, in
confined spaces a supplied air respirator is required. In large open bays and
outdoors the potential for overexposure is extremely remote and a lesser
requirement for a respirator may exist.

2-5. DRYING (recognition). Solvents are released during the drying or curing
process. The vapor concentrations measured at many paint operations indicate
that levels are usually well below current health standards. However, the
solvent vapors are typically Irritating to the eyes and have low odor
thresholds. Drying painted items in an occupied, unventilated space may cause
solvent overexposure. After drying, there is no hazard from the solvents.
