TRACT. MAY BE HARMFUL IF SWALLOWED.
Potential Health Effects
D&J Chemicals Co., Ltd.
Information on the human health effects from exposure to this substance is
limited.
Inhalation:
Inhalation of dust is irritating to the upper respiratory tract.
Ingestion:
Moderately toxic by ingestion based on LD50 data.
Skin Contact:
Causes moderate skin irritation based on Draize information for rabbits.
Eye Contact:
Causes severe eye irritation based on Draize information for rabbits.
Chronic Exposure:
No information found.
Aggravation of Pre-existing Conditions:
No information found.
4. First Aid Measures
Inhalation:
Remove to fresh air. If not breathing, give artificial respiration. If breathing is
difficult, give oxygen. Call a physician.
Ingestion:
Induce vomiting immediately as directed by medical personnel. Never give
anything by mouth to an unconscious person. Get medical attention.
Skin Contact:
Remove any contaminated clothing. Wash skin with soap or mild detergent and
water for at least 15 minutes. Get medical attention if irritation develops or
persists.
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.
D&J Chemicals Co., Ltd.
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.
7. Handling and Storage
Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect
from physical damage. Separate from oxidizing materials. Store in the dark.
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
D&J Chemicals Co., Ltd.
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.
9. Stability and Reactivity
Stability:
Stable under ordinary conditions of use and storage.
Hazardous Decomposition Products:
Carbon dioxide and carbon monoxide may form when heated to decomposition.
Hazardous Polymerization:
Will not occur.
Incompatibilities:
Oxidizing agents, bases, alkali metals and amines.
Conditions to Avoid:
Heat and incompatibles.
10. Toxicology Information
LD50 oral mouse: 1600mg/kg
Standard Draize/rabbit skin: 500mg/24H, moderate;
rabbit eye: 750ug/24H, severe.
11. Ecological Information
Environmental Fate:
When released into the air, this material is expected to be readily degraded by
reaction with photochemically produced hydroxyl radicals. When released into
the soil, this material is expected to readily biodegrade. When released into
water, this material is expected to readily biodegrade. This material is not
expected to significantly bioaccumulate.
Environmental Toxicity:
No information found.

12. Disposal Considerations
Whatever cannot be saved for recovery or recycling should be managed in an
appropriate and approved waste disposal facility. Processing, use or
contamination of this product may change the waste management options.
State and local disposal regulations may differ from federal disposal
regulations. Dispose of container and unused contents in accordance with
federal, state and local requirements.
13. Transport Information
Not regulated.
