(4) Accessibility. Ensure that containers of paint materials are readily accessible at all times.
Do not stack other materials on top of paint materials. In addition, you should--
Store and issue containers in the order of the manufacture date shown on the labels.
Use material bearing the oldest date first. If the manufacture date is not shown on the
container, you may consider the date of receipt as the approximate manufacture date
for purposes of storage and issue.
(5) Temperature. For best results, the temperature of paint materials should be between 65
and 85€F (room-temperature range) at the time of use. If storage conditions result in paint temperatures
being below 55€F or above 95€F, you should store the container at room temperature for approximately
24 hours before use.
(6) Internal pressure. Containers of paint may develop internal pressure from high
temperatures. For safe release of internal pressure, use the following precautions:
(a) Internal pressure is apparent as bulging in light-gauge tin containers, but it is not
evident in heavy-gauge steel drums. Use care when opening containers so that you allow the pressure to
dissipate slowly before the seal is completely removed. If you fail to observe this precaution, you may
be spattered with paint that explodes because of a sudden release of pressure.
(b) Open containers sealed with bungs by turning out the bung slowly until a hissing
sound is heard. When the hissing ceases, indicating equalization of pressure with the atmosphere, the
bung can be completely removed.
(c) Containers that are bulged or misshapened from internal pressure should have a small
hole punctured in the top to release the pressure. Use a fine, nonspark producing tool, such as aluminum
or copper. After correcting the bulged or misshapened containers, post signs on the storage building that
read: FLAMMABLE-KEEP FIRE AWAY.
c. Disposing. Dispose of paints and chemicals when they become old, dried out, or
contaminated with foreign matter. Take them to a sanitary fill, open the containers, and toss them into
the fill. When acids become contaminated or have served their purpose, bury them about 2 feet deep in
a designated disposal area. Remember, chemicals are dangerous; therefore, follow all directions and
procedures when you use or dispose of them.
