3. Hazards Identification
Emergency Overview
--------------------------
Inhalation: No information found,
but compound should be handled as a potential health hazard.
Ingestion: No information found,
but compound should be handled as a potential health hazard.
Skin Contact: No information found,
but compound should be handled as a potential health hazard.
Eye Contact: No information found,
but compound should be handled as a potential health hazard.
Chronic Exposure: No information
found, but compound should be handled as a potential health hazard.
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: Get medical attention
immediately. Never give anything by mouth to an unconscious person.
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 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. Contact with strong oxidizers may cause
fire or explosion.
Fire Extinguishing Media: Use any
means suitable for extinguishing surrounding fire.
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
Warning! Use appropriate protection to avoid inhalation exposure and skin and
eye contact.
Remove all sources of ignition. Ventilate area of leak or spill. Wear
appropriate personal protective equipment as specified in Section 8. Spills:
Clean up spills in a manner that does not disperse dust into the air. Use
non-sparking tools and equipment. Reduce airborne dust and prevent scattering
by moistening with water. Pick up spill for recovery or disposal and place in
a closed container.
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 the dust or mist is apparent, a
half-face dust/mist respirator may be worn. 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 impervious
protective clothing, including boots, gloves, lab coat, apron or coveralls, as
appropriate, to prevent skin contact.
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.

conditions of use and storage.
Hazardous Decomposition Products:
Burning may produce carbon monoxide, carbon dioxide, sulfur oxides, and
nitrogen oxides.
Hazardous Polymerization: This
