SIRIUS RED F3B (Colour Index No. 35780) (C47H50N14O9Na2S2)

Chlorantine fast red 7BLN, 5BRL, durazol brilliant red B, chloramine chrome red BL, pontamine fast red 7BNL, fast red B, 5B or 8B, solantine red 8BLN.
Avoid skin and eye contact.
Avoid inhalation or ingestion of the powder.
Wash hands thoroughly after handling.
Dark red powder, polyazo group of dyes.
There is insufficient data available on the toxicity of this dye. However, other dyes in this group are known to be mutagenic and carcinogenic. Handle with care. It is a skin irritant and may irritate eyes.
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 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 advice.
Heating produces toxic fumes of carbon, nitrogen and sulphur.
Store in a cool, dry atmosphere away from heat.
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.
Leather gloves, heavy face shield and laboratory coat. Work from behind a barricade (body shield or wall). Avoid unnecessary heat, friction or impact.
Absorb the liquid with paper or vermiculite. If it is a solid, dampen then brush on to paper with great care. Place in a plastic bag and remove outside for burning.
Sponge up with water, followed by decontamination with 10% ammonium ceric nitrate solution. 'Kill', by adding to a greater stoichiometric amount of ammonium ceric nitrate solution with agitation sufficient to provide suspension of all solids. Cool the reaction. The organic azides and heavy metal azides are explosive. Alkali and alkaline earth azides are not considered explosives under normal laboratory conditions. Keep the stock of azides very low. Stamp the date of receipt upon the package.
