3. Hazards Identification
Emergency Overview :
WARNING! Causes irritation to skin, eyes and respiratory track.
Harmful if swallowed or
inhaled. May affect the heart, blood, thyroid and central nervous
system.
Health Rating: 1 - Slight
Flammability Rating: 0 - None
Reactivity Rating: 1 - Slight
Contact Rating: 1 - Slight
Lab Protective Equip: GOGGLES; LAB COAT
Storage Color Code: Orange (General Storage) Potential Health
Effects
Inhalation:
May cause irritation to the respiratory tract. Symptoms may include
coughing and shortness of breath.
Ingestion:
May cause vomiting, disorientation, weakness, low blood pressure,
convulsions and death which may be delayed. The probable lethal
dose is between 15-30 grams.
Skin Contact:
Causes irritation to skin. Symptoms include redness, itching,
and pain.
Eye Contact: Causes irritation, redness, and pain.
Chronic Exposure:
Prolonged or repeated skin exposure may cause dermatitis. Repeated
ingestion of small amounts may cause hives, abnormal bleeding,
enlarged thyroid, weakness, confusion, diarrhea, psychosis, and
collapse.
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. Get medical attention.
Ingestion:
If swallowed, Don't induce vomitting. Give large quantities of
water. Never give anything by mouth to an unconscious person.
Get medical attention immediately.
Skin Contact:
Immediately flush skin with plenty of 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.
5. Fire Fighting Measures
Fire: Not considered to be a fire hazard.
Explosion: Not considered to be an explosion hazard.
Fire Extinguishing Media: Water, sand earth, foam.
Special Information: In the event of a fire, wear full protective
clothing and self-contained breathing apparatus with full face
piece operated in the pressure demand or other positive pressure
mode. Poisonous gases are produced in fire.
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 light-resistant container, stored in
a cool, dry, ventilated area. Protect against physical damage.
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.
8. Exposure Controls/Personal Protection
Airborne Exposure Limits: None established.
Ventilation System: In general, dilution ventilation is a satisfactory
health hazard control for this substance. However, if conditions
of use create discomfort to the worker, a local exhaust system
should be considered.
Personal Respirators: For conditions of use where exposure to
dust or mist is apparent and engineering controls are not feasible,
a particulate respirator may be worn. If oil particles (e.g. lubricants,
cutting fluids, glycerine, etc.) are present, use a 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.
