Composition, Information on Ingredients
||C.I. acid orange 52
Risk Phrases: 25
Section 3 - Hazards
Appearance: orange. Harmful if swallowed. Warning! May
cause respiratory and digestive tract irritation. May cause eye and skin
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.
May cause respiratory tract irritation. The toxicological properties of this
substance have not been fully investigated.
Section 4 - First Aid
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 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
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.
Section 6 -
Accidental Release Measures
Information: Use proper personal protective equipment as indicated in
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
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
Storage: Store in a cool, dry, well-ventilated
area away from incompatible substances. Keep containers tightly closed.
Section 8 - Exposure
Controls, Personal Protection
Controls: Use adequate ventilation to keep airborne concentrations low.
