Storage and handling
Carbon black should be stored in a clean, dry,
uncontaminated area away from exposure to high
temperatures, open flame sources and strong oxidizers
(e.g., chlorates, bromates, and nitrates). Since
carbon black will adsorb moisture and chemical
vapors, it should be stored in closed containers.
Housekeeping
Spill clean-up and general housekeeping are very
important for controlling carbon black exposures.
Carbon black dust spreads easily in air through
virtually any air current or movement. Additionally,
because carbon black is a pigment, it may stain
exposed surfaces. Housekeeping procedures that
avoid the production of dust or generation of
fugitive emissions in the process are highly recommended.
Dry vacuuming, with appropriate filtration, is
the preferred method for removing surface dust
and cleaning spills. Dry sweeping should be avoided.
Bulk carbon black should always be covered or
contained. Care should be taken to avoid generating
conditions that may result in unnecessary exposure.
Acute First Aid
There is no evidence to suggest that acute exposure
to carbon black may result in life threatening
injury or illness. Carbon black is not a respiratory
irritant, as defined by the Occupational Safety
and Health Administration (OSHA), and does not
produce respiratory or dermal sensitization. Ingestion
is an unlikely method of accidental exposure.
Like many dusts, inhalation may initiate a bronchial
response among individuals with pre-existing lung
conditions.
Inhalation: Short-term
exposures to elevated concentrations may produce
temporary discomfort to the upper respiratory
tract, which may result in coughing and wheezing.
Removal from carbon black exposure is normally
sufficient to cause symptoms to subside without
lasting effects.
Skin: Carbon
black dust or powder may cause drying of the skin
with repeated and prolonged contact. Skin drying
may also result from frequent washing of carbon
black contaminated skin. Carbon black may be washed
from the skin using mild soap and water along
with gentle scrubbing action. A waterless skin
cleaner may also be used. Repeat washing may be
necessary to remove carbon black. A protective
barrier cream on exposed skin surfaces may also
be an effective method for minimizing dermal exposure.
Ingestion: No
adverse effects are expected from carbon black
ingestion. Do not induce vomiting.
Eye: Carbon black
is not a chemical irritant. Treat symptomatically
for mechanical irritation. Rinse eyes thoroughly
with water to remove dust. If irritation persists
or symptoms develop, seek medical attention.
