ALIZARIN (Colour Index No. 58000) (Cl4H8O4)
Alizarin P, VI or Le, mordant red II, pigment red 83, 1,2-dihydroxy-9,10-anthracenedione.
Red, combustible powder, anthraquinone group of dyes.
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.
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.
Store in a cool, dry atmosphere.
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.
