ABC of Safety in the Biological Sciences
FAST GREEN FCF (Colour Index No. 42053) (C37H34N2O10S3Na2)
SYNONYMS
Food green 3, alzen food no. 3.
CHARACTERISTICS
Maroon powder with a metallic sheen. Aminotriarylmethane group
of dyes.
INCOMPATIBILITY
Heating produces toxic fumes of nitrogen and sulphur.
HEALTH HAZARD DATA
This substance is a known animal carcinogen having produced
sarcomas in rats. There is no data available about its effects
upon humans but because of its chemical structure it is deemed
to be a skin, eye and mucous membrane irritant.
HANDLING and GENERAL PRECAUTIONS
Use a fume hood.
Avoid skin and eye contact.
Keep away from heat.
Avoid inhalation or ingestion.
Wash hands thoroughly after handling.
Use a fume hood to avoid all contact with 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 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.
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. Keep
warm and allow to rest. If discomfort or irritation persist seek
medical attention.
Ingestion wash 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 medical advice.
STORAGE
Store in a cool, dry atmosphere away from heat.
DISPOSAL
WEAR:
Leather gloves, heavy face shield and laboratory coat. Work from
behind a barricade (body shield or wall). Avoid unnecessary
heat, friction or impact.
SPILLS:
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.
OR
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.
