“For these reasons, we recommend
half-face respirators with NIOSH
P100, R100, or N100 particulate
±lters as the minimum respiratory
equipment used for CARC sanding
and grinding operations. You should
also wear coveralls that can be washed
or disposed of at work and wash
carefully before eating, drinking,
smoking,
applying
cosmetics
or
going home from work. Remember
to use skin and eye protection when
painting with or removing CARC.
“The dust residue from sanding and
grinding on CARC coatings should
be handled as if it were hazardous
waste.
Cleaning
with
a
HEPA
vacuum cleaner is the best method.
However, you can use wet cleanup
methods or sweeping compounds as
an alternative. CARC residue should
never
be swept dry or dispersed with
compressed air.
“Items that are used in sanding and
grinding operations—including sand-
paper and abrasive blasting grit—
should also be considered hazardous
waste and disposed of properly.
Applying CARC by spray requires the use of
respiratory protection because the liquid coatings contain
isocyanates and organic solvents. WD CARC has much
lower levels of organic solvents but may actually contain
increased amounts of prepolymers with hexamethylene
diisocyanate, which is a type of isocyanate.
“Normally, airline respirators are used when painting
materiel with CARC in spray booths. For smaller spot
painting tasks, air purifying respirators with organic
vapor cartridges and paint pre±lters are adequate if
okayed by an industrial hygienist. Some brush and roller
spot painting tasks may not require the use of respiratory
protection. Ask your industrial hygienist to evaluate the
work you are doing.”
