BASIC FUCHSIN Colour Index No. 42510
Basic fuchsin is a mixture of pararosanilin, rosaniline and magenta II.

Pararosanilin (C19H18N3Cl)

Rosaniline (C20H20N3Cl)

Magenta II (C21H22N3Cl)

Basic red 9, basic violet 14, solvent red 41, free base, fuchsine base, magenta base, rosaniline base, waxoline red A, fuchsine HF base.
Dark green powder or greenish crystals with a bronze lustre. Triaminotriphenylmethane group of dyes.
Heating produces toxic fumes of chlorides.
This substance is a potential carcinogen and should therefore be handled with extreme care. It is toxic and an irritant. Acute exposure to the skin may cause irritation. Prolonged contact may cause dermatitis. Acute exposure to the eyes may cause redness and irritation. Prolonged exposure may cause conjunctivitis. Acute exposure to the respiratory system may cause coughing and irritation. Ingestion may cause gastrointestinal irritation, nausea, vomiting and diarrhoea.
Use a fume hood.
Potential carcinogen.
Avoid skin and eye contact.
Avoid inhalation or ingestion of the powder.
Keep away from heat.
Wash hands thoroughly after handling.
Use a fume hood to keep the level of exposure to a minimum. Wear protective clothing. A long sleeved laboratory coat or gown, rubber gloves, safety goggles and a face mask as a minimum standard.
Skin ­ remove contaminated clothing and immediately wash the affected area with soap or mild detergent and large amounts of water until all evidence of the dye has been removed (approximately 15 minutes). If irritation persists or dermatitis develops seek medical attention. Wash contaminated clothing before re­use.
Eyes ­ immediately wash the affected eye with large amounts of water until all evidence of the dye has been removed (approximately 15 minutes). If irritation or pain persist seek immediate medical attention.
Inhalation ­ remove from the area of exposure to fresh air. If breathing has ceased apply artificial respiration. Give oxygen if necessary. Keep warm and allow to rest. Seek medical advice or if distress continues seek immediate medical attention.
Ingestion ­ wash out the mouth thoroughly with water and give two to four glasses of water to drink. If the victim is conscious induce vomiting by touching a finger to the back of the throat. Seek immediate medical attention.
Store in a cool, dry atmosphere away from heat.
A gas leak keep the concentration of the gas below the explosive mixture range by forced ventilation. Remove the tank to an open area and allow dissipation to the atmosphere. Attempt to cap the valve outlet and return the tank to the supplier.
A liquid 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.
A gas pipe the gas into an incinerator or lower into a pit and allow to burn.
A liquid atomise into an incinerator. Combustion may be improved by mixing with a more flammable solvent.
A solid 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.
