Potential Health Effects
----------------------------------
Inhalation:
May cause irritation to the respiratory tract, (nose and throat); symptoms
may include coughing and sore throat.
Ingestion:
Large oral doses may cause abdominal pain, sore throat, nausea, and
vomiting.
Skin Contact:
If allowed to remain on skin, may cause irritation with redness and pain.
Eye Contact:
Causes irritation with 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:
Give several glasses of water to drink to dilute. If large amounts were
swallowed, get medical advice.
Skin Contact:
Wash exposed area with soap and water. Get medical advice if irritation
develops.
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:
Flash point: 121C (250F) CC
Autoignition temperature: 570C (1058F)
Explosion:
Fine dust dispersed in air in sufficient concentrations, and in the
presence of an ignition source is a potential dust explosion hazard.
Minimum explosible concentration 0.011 g/l. Vapor may explode if ignited in
an enclosed area. Vapor from molten benzoic acid may form explosive mixture
with air.
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. 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. 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, stored in a cool, dry, ventilated area.
Protect against physical damage. Isolate from any source of heat or
ignition. Isolate from oxidizing materials. Isolate from flammable
materials.
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 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.

Environmental Fate:
When released into the soil, this material may leach into groundwater. When
released into the soil, this material is expected to readily biodegrade.
When released into the soil, this material is expected to have a half-life
between 1 and 10 days. When released into water, this material is expected
to readily biodegrade. When released into the water, this material is
expected to have a half-life between 1 and 10 days. When released into
water, this material is not expected to evaporate significantly. This
material has a log octanol-water partition coefficient of less than 3.0.
This material may bioaccumulate to some extent. When released into the air,
this material is expected to be moderately removed from the atmosphere by
wet deposition. When released to the air, this material is subject to
removal from the atmosphere by gravitational settling.
