ALIZARIN (Colour Index No. 58000) (Cl4H8O4)
SYNONYMS
Alizarin P, VI or Le, mordant red II, pigment red 83,
1,2-dihydroxy-9,10-anthracenedione.
CHARACTERISTICS
Red, combustible powder, anthraquinone group of dyes.
INCOMPATIBILITY
Non known, although heating may produce toxic fumes.
HEALTH HAZARD DATA
There is insufficient data available on the toxic effects of
this dye. However, other dyes in this group (indigo carmine) are
known to be mutagenic and highly toxic. Handle with caution.
HANDLING and GENERAL PRECAUTIONS
Avoid skin and eye contact.
Avoid inhalation or ingestion of the powder.
Avoid creating a dust.
Keep away from heat or naked flames.
Wash hands thoroughly after handling.
Use a fume hood to minimise exposure to this substance. Wear
protective clothing. A long sleeved laboratory coat or gown,
rubber gloves, safety goggles and a face mask as a minimum
standard.
TREATMENTS
Skin immediately remove contaminated clothing and wash the
affected area with soap or mild detergent and large amounts of
water until all evidence of the chemical has been removed
(approximately 15 minutes). If irritation develops and persists
seek medical attention. Wash contaminated clothing before
reuse.
Eyes immediately wash the affected eye with large amounts of
water until all evidence of the chemical has been removed
(approximately 15 minutes). If irritation or pain persist seek
medical attention.
Inhalation remove from the area of exposure to fresh air. If
breathing has ceased apply artificial respiration. Keep warm and
allow to rest. If irritation persists or develops seek medical
attention.
Ingestion wash out the mouth thoroughly with water and give
water to drink. Seek immediate medical attention.
STORAGE
Store in a cool, dry atmosphere.
DISPOSAL
Wear rubber gloves, face shield and laboratory coat. Have an all
purpose canister respirator available.
SPILLS: A liquid solution - absorb on paper. Evaporate in an
iron pan in a flame proof fume hood then burn the paper.
A solid - sweep on to paper and place in an iron pan in a fume
hood. Burn the paper and compound.
PACKAGE LOTS: Make up packages in paper or other flammable
material. Burn in the incinerator. Or the solid may be dissolved
in a flammable solvent and sprayed into a fire chamber.
ENVIRONMENT
No data available.
