Potential Health Effects
----------------------------------
Inhalation:
Causes irritation to the respiratory tract. Symptoms may include coughing, shortness of
breath. Higher concentrations may cause severe irritation.
Ingestion:
Causes irritation to the gastrointestinal tract. Symptoms may include nausea, vomiting and
diarrhea.
Skin Contact:
Causes irritation to skin. Symptoms include redness, itching, and pain.
Eye Contact:
Causes irritation, redness, and pain.
Chronic Exposure:
No information found.
Aggravation of Pre-existing Conditions:
Persons with impaired respiratory function may be more susceptible to the effects of the
substance.
4. First Aid Measures
Inhalation:
Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give
oxygen. Get medical attention.
Ingestion:
Give large amounts of water to drink. Never give anything by mouth to an unconscious
person. Get medical attention.
Skin Contact:
Wipe off excess material from skin then immediately flush skin with plenty of water for at
least 15 minutes. Remove contaminated clothing and shoes. Get medical attention. Wash
clothing before reuse. Thoroughly clean shoes before reuse.
Eye Contact:
Immediately flush eyes with plenty of water for at least 15 minutes, lifting lower and upper
eyelids occasionally. Get medical attention immediately.
5. Fire Fighting Measures
Fire:
As with most organic solids, fire is possible at elevated temperatures or by contact with an
ignition source.
Explosion:
Fine dust dispersed in air in sufficient concentrations, and in the presence of an ignition
source is a potential dust explosion hazard.
Fire Extinguishing Media:
Water spray, dry chemical, alcohol foam, or carbon dioxide.
Special Information:
In the event of a fire, wear full protective clothing and NIOSH-approved self-contained
breathing apparatus with full facepiece operated in the pressure demand or other positive
pressure mode.
6. Accidental Release Measures
Remove all sources of ignition. Ventilate area of leak or spill. Keep unnecessary and
unprotected people away from area of spill. Wear appropriate personal protective equipment
as specified in Section 8. Spills: Pick up and place in a suitable container for reclamation or
disposal, using a method that does not generate dust. US Regulations (CERCLA) require
reporting spills and releases to soil, water and air in excess of reportable quantities. The toll
free number for the US Coast Guard National Response Center is (800) 424-8802.
7. Handling and Storage
Keep in a tightly closed container. Store in a cool, dry, ventilated area away from sources of
heat or ignition. Protect against physical damage. Store separately from reactive or
combustible materials, and out of direct sunlight. Containers of this material may be
hazardous when empty since they retain product residues (dust, solids); observe all
warnings and precautions listed for the product.
8. Exposure Controls/Personal Protection
Airborne Exposure Limits:
None established.
Ventilation System:
A system of local and/or general exhaust is recommended to keep employee exposures as
low as possible. Local exhaust ventilation is generally preferred because it can control the
emissions of the contaminant at its source, preventing dispersion of it into the general work
area. Please refer to the ACGIH document, Industrial Ventilation, A Manual of
Recommended Practices, most recent edition, for details.
Personal Respirators (NIOSH Approved):
For conditions of use where exposure to dust or mist is apparent and engineering controls
are not feasible, a particulate respirator (NIOSH type N95 or better filters) may be worn. If
oil particles (e.g. lubricants, cutting fluids, glycerine, etc.) are present, use a NIOSH type R
or P filter. For emergencies or instances where the exposure levels are not known, use a
full-face positive-pressure, air-supplied respirator. WARNING: Air-purifying respirators do
not protect workers in oxygen-deficient atmospheres.
Skin Protection:
Wear protective gloves and clean body-covering clothing.
Eye Protection:
Use chemical safety goggles and/or full face shield where dusting or splashing of solutions
is possible. Maintain eye wash fountain and quick-drench facilities in work area.
