EMERGENCY OVERVIEW
Appearance: orange solid.
Warning! Harmful if swallowed. May cause eye,
skin, and respiratory tract irritation.
Target Organs: None.
Potential Health Effects
Eye:
May cause eye irritation. This product contains an anionic dye.
Similar dyes have not caused injury to the cornea or conjunctiva in
documented exposure cases with human or rabbit eyes.
Skin:
May cause skin irritation.
Ingestion:
Harmful if swallowed. May cause gastrointestinal irritation with
nausea, vomiting and diarrhea.
Inhalation:
May cause respiratory tract irritation. The toxicological properties
of this substance have not been fully investigated.
Chronic:
No information found.
Section 4 - First Aid Measures
|
Eyes:
Flush eyes with plenty of water for at least 15 minutes, occasionally
lifting the upper and lower eyelids. Get medical aid.
Skin:
Get medical aid if irritation develops or persists. Wash clothing
before reuse. Flush skin with plenty of soap and water.
Ingestion:
If victim is conscious and alert, give 2-4 cupfuls of milk or water.
Never give anything by mouth to an unconscious person. Get medical
aid immediately.
Inhalation:
Remove from exposure and move to fresh air immediately. If not
breathing, give artificial respiration. If breathing is difficult,
give oxygen. Get medical aid.
Notes to Physician:
Treat symptomatically and supportively.
Section 5 - Fire Fighting Measures
|
General Information:
As in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. During a fire, irritating and highly toxic gases
may be generated by thermal decomposition or combustion. Vapors may
be heavier than air. They can spread along the ground and collect
in low or confined areas.
Extinguishing Media:
Use extinguishing media most appropriate for the surrounding fire.
Use water spray, dry chemical, carbon dioxide, or appropriate foam.
Flash Point: Not applicable.
Autoignition Temperature: Not applicable.
Explosion Limits, Lower:Not available.
Upper: Not available.
NFPA Rating:
(estimated) Health: 2; Flammability: 0; Instability: 0
Section 6 - Accidental Release Measures
|
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Clean up spills immediately, observing precautions in the Protective
Equipment section. Sweep up or absorb material, then place into a
suitable clean, dry, closed container for disposal. Avoid generating
dusty conditions. Provide ventilation.
Section 7 - Handling and Storage
|
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use with adequate ventilation. Avoid contact with
skin and eyes. Keep container tightly closed. Do not ingest or
inhale.
Storage:
Store in a cool, dry, well-ventilated area away from incompatible
substances. Keep containers tightly closed.
Section 8 - Exposure Controls, Personal Protection
|
Engineering Controls:
Use adequate ventilation to keep airborne concentrations low.
