ABC of Safety in the Biological Sciences
METANIL YELLOW (Colour Index No. 13065) (C18H14N3O3SNa)
SYNONYMS
Acid yellow R, soluble yellow OL, yellow M, tropaeolin G, orange
MNO or MN.
GENERAL PRECAUTIONS
Avoid skin and eye contact.
Avoid inhalation or ingestion of the powder.
Keep away from heat.
Wash hands thoroughly after handling.
CHARACTERISTICS
Brownishyellow powder. Monoazo group of dyes.
HEALTH HAZARD DATA
There is insufficient data available on the toxic effects of
this dye. However, other dyes in this group are known to be
highly toxic and carcinogenic. Handle with care. It is a skin,
eye and respiratory tract irritant.
TREATMENTS
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 dye 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 dye 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.
INCOMPATIBILITY
Heating produces toxic fumes of carbon, nitrogen and sulphur.
STORAGE
Store in a cool, dry atmosphere away from heat.
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.
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.
