Potential Health Effects
----------------------------------
Inhalation: May cause
irritation to the respiratory tract. Symptoms may include coughing and
shortness of breath.
Ingestion: Large oral doses may
cause irritation to the gastrointestinal tract.
Skin Contact: May cause
irritation with redness and pain.
Eye Contact: May cause
irritation, redness and pain.
Chronic Exposure: No
information found.
Aggravation of Pre-existing
Conditions: No information found.
4. First Aid
Measures
Inhalation: Remove to fresh
air. Get medical attention for any breathing difficulty.
Ingestion: Induce vomiting
immediately as directed by medical personnel. Never give anything by mouth to
an unconscious person. Get medical attention.
Skin Contact: Immediately flush
skin with plenty of water for at least 15 minutes. Remove contaminated
clothing and shoes. Wash clothing before reuse. Thoroughly clean shoes before
reuse. Get medical attention if irritation develops.
Eye Contact: Immediately flush
eyes with plenty of water for at least 15 minutes, lifting upper and lower
eyelids occasionally. Get medical attention if irritation persists.
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
Ventilate area of leak or spill. Wear appropriate personal protective
equipment as specified in Section 8. Spills: Sweep up and containerize for
reclamation or disposal. Vacuuming or wet sweeping may be used to avoid dust
dispersal.
7. Handling and
Storage
Keep in a tightly closed container, stored in a cool, dry, ventilated area.
Protect against physical damage. 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. Maintain eye wash fountain and quick-drench facilities in work
area.
