Potential Health Effects
----------------------------------
Information on the human health effects from exposure to this substance is
limited.
Inhalation: Causes irritation to the respiratory tract. Symptoms may
include coughing, shortness of breath.
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. Photosensitizer.
Eye Contact: Causes irritation, redness, and pain.
Chronic Exposure: Cyclic hydrocarbons may cause dermatitis on prolonged
or frequent contact with the skin. The substance may also produce liver or
kidney complications.
Aggravation of Pre-existing Conditions: Persons with pre-existing skin
disorders or eye problems or 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: 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 soap and water.
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 upper and lower eyelids occasionally. Get medical
attention.
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. Isolate from
incompatible substances. 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.
