ABC of Safety in the Biological Sciences
MARTIUS YELLOW (Colour Index No. 10315 (C10H6N2O5)
SYNONYMS
Manchester yellow, naphthol yellow.
GENERAL PRECAUTIONS
Avoid skin and eye contact.
Avoid inhalation or ingestion.
Keep away from heat.
Wash hands thoroughly after handling.
CHARACTERISTICS
Orange yellow powder. Nitro group of dyes.
HEALTH HAZARD DATA
This substance is very toxic. It can be absorbed through the
skin in concentrations sufficient to cause toxicity. It is an
eye irritant. Inhalation or ingestion of the powder will cause
systemic poisoning.
TREATMENTS
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 evidence of toxicity develops
seek immediate 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 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 necessary. Keep warm and allow to rest. Seek immediate
medical attention.
Ingestion if the victim is conscious rinse the mouth
thoroughly with water and seek immediate medical attention.
Apply artificial respiration if necessary.
INCOMPATIBILITY
Heating produces toxic fumes of nitrogen compounds.
STORAGE
Store in a cool, dry atmosphere away from heat.
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:
Butyl rubber gloves, laboratory coat and self contained
breathing apparatus.
SPILLS:
On skin and clothing: wash skin with strong soap solution
immediately. Rinse thoroughly. Contaminated clothing should be
removed, dried and washed with strong soap solution or
destroyed. It may be necessary to destroy shoes by burning.
Small spills: absorb liquid on paper towels. Brush solids on to
paper. Place in an iron pan and allow evaporation in a fume
hood. Add crumpled paper and burn. Wash spill site with a strong
soap solution.
Large spills: cover with sand and soda ash mixture (90/10). Mix
and shovel into a cardboard box. Pack with a large excess of
crumpled paper. Burn in an open pit or incinerator equipped with
an afterburner and scrubber.
PACKAGE LOTS: Either
1 Pour or sift on to a thick layer of sand and soda ash mixture
(90/10). Mix, and shovel into a heavy paper box with much paper
packaging. Burn in an incinerator. The fire may be augmented
with scrap wood. Stay on the upwind side.
OR
2 Dissolve in a flammable solvent and spray into the firebox of
an incinerator equipped with an afterburner and scrubber.
