GENERAL PRECAUTIONS
Mutagen not to be handled by pregnant staff.
Use a fume hood potential carcinogen.
Avoid skin and eye contact.
Keep away from heat.
Keep away from oxidising materials.
Avoid creating a dust.
Wash hands thoroughly after handling.
CHARACTERISTICS
Red brown, combustible powder. Disazo group of dyes.
HEALTH HAZARD DATA
This is a combustible substance and should never be handled
close to heat or a naked flame. It is an animal mutagen and a
potential carcinogen. It must never be handled by staff who are
pregnant and should only be handled beneath a fume hood. It is
highly toxic by the intravenous route but has not been
quantified through other routes. The dust when finely divided
can be explosive. It is an eye and respiratory tract irritant.
TREATMENTS
Skin remove contaminated clothing then 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 seek medical advice. 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 persists seek
immediate medical attention.
Inhalation remove from the area of exposure to fresh air. If
breathing has ceased apply artificial respiration. Give oxygen
if required. Keep warm and allow to rest. Seek immediate medical
attention.
Ingestion wash out the mouth thoroughly with water and give
water to drink. If the victim is conscious induce vomiting by
touching a finger to the back of the throat. Seek immediate
medical attention.
INCOMPATIBILITY
Heating produces toxic fumes of nitrogen compounds. Can react
with oxidising materials. This is a combustible substance and
should never be handled close heat or a naked flame.
STORAGE
Store in a cool, dry atmosphere away from heat or oxidising
materials.
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. 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.
