Emergency Overview:
WARNING! CAUSES IRRITATION TO SKIN, EYES AND RESPIRATORY
TRACT. MAY BE HARMFUL IF SWALLOWED.
D&J Chemicals Co., Ltd.
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. Extremely large oral dosages may produce
gastrointestinal disturbances. Calcium deficiency in blood may result in severe
cases of ingestion.
Skin Contact:
Causes irritation to skin. Symptoms include redness, itching, and pain.
Eye Contact:
Highly irritating; may also be abrasive.
Chronic Exposure:
Chronic or heavy acute ingestion may cause tooth enamel erosion.
Aggravation of Pre-existing Conditions:
No adverse health effects expected.
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:
Autoignition temperature: 1011C (1852F)
As with most organic solids, fire is possible at elevated temperatures or by
D&J Chemicals Co., Ltd.
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
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
D&J Chemicals Co., Ltd.
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 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.
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:
Metal nitrates (potentially explosive reaction), alkali carbonates and
bicarbonates, potassium tartrate. Will corrode copper, zinc, aluminum and their
alloys.
Conditions to Avoid:
Heat and incompatibles.
