FIRE AND EXPLOSION DATA
========================================================================
Fire:
Flash point: 180掳C (356掳F) OC
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. Water or foam may cause frothing.
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.
========================================================================
REACTIVITY DATA
========================================================================
Stability: Stable under ordinary conditions of use and storage.
Hazardous Decomposition Products:
May emit oxides of carbon and phosphorous oxides and/or phosphine when heated to decomposition.
Hazardous Polymerization: Will not occur.
Incompatibilities: Strong acids and strong oxidizers.
Conditions to Avoid: Heat, flames, ignition sources and incompatibles.

HEALTH HAZARD DATA
========================================================================
Potential Health Effects
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. Has
caused weakness and incoordination in laboratory animals.
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: No information found.
========================================================================
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:
Immediately flush skin with plenty of soap and 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.

PREVENTATIVE MEASURES
========================================================================
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 protective gloves and clean body-covering clothing.
Eye Protection:
Use chemical safety goggles. Maintain eye wash fountain and quick-drench facilities in work area.
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. 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.
========================================================================
ENVIRONMENTAL PROTECTION DATA
========================================================================
Remove all sources of ignition. Ventilate area of leak or spill. Wear appropriate personal protective
equipment. 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.
