EOSIN B (Colour Index No. 45400) (C20H6N2O9Br2Na2)
Eosine I bluish, eosin BN, eosin BA, eosin BS, eosin BW, eosin DHV, saffrosin, eosin scarlet B, scarlet J, scarlet JJ, scarlet V, napolin G, imperial red, acid red 91.
Red powder, may explode when exposed to heat or a naked flame. Xanthene group of dyes.
Heating produces highly toxic fumes of bromine and oxides of sodium. May explode when exposed to heat or a naked flame.
HEALTH HAZARD DATA
This substance may explode when exposed to heat or a naked flame. It is a skin irritant and has also caused photosensitisation, cheilitis and stomatitis when used in lipstick preparations. Causes transient eye irritation. There is no data available regarding inhalation or ingestion. Because of its chemical structure it is assumed that it will irritate the respiratory system.
HANDLING and GENERAL PRECAUTIONS
Avoid skin and eye contact.
Keep away from heat or naked flames.
Wash hands thoroughly after handling.
Wear protective clothing to avoid skin or eye contact. A long sleeved laboratory coat or gown, rubber gloves, safety goggles as a minimum standard.
Skin 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 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 persists seek immediate medical attention.
Inhalation remove from the area of exposure to fresh air. Keep warm and allow to rest. If discomfort develops and persists seek medical attention.
Ingestion wash out the mouth thoroughly with water and give two four glasses of water to drink. Induce vomiting by touching a finger to the back of the throat. If discomfort persists seek medical advice. Never give anything by mouth to a person that is not conscious.
Store in a cool, dry atmosphere away from heat or naked flame.
Butyl rubber gloves, laboratory coat, self contained breathing apparatus and protective shoes.
On skin and clothing: wash skin with a strong soap solution immediately. Rinse well. Contaminated clothing should be removed and cleaned at once or destroyed by burning.
Small spills: absorb liquid on paper towels or vermiculite; sweep solid spills on to paper. Put on an iron pan in a fume hood and allow to evaporate. Burn the paper or vermiculite in the absence of other inflammables. Wash the site thoroughly with a strong soap solution.
Large spills: absorb or mix with vermiculite, sodium bicarbonate or sand. Package this in a paper carton and burn in an open pit. Use wood scraps and crumpled paper to augment burning. Wash the site thoroughly with a strong soap solution.
PACKAGE LOTS: Either
1 Pour os sift on to sodium bicarbonate or a sand, soda ash mixture (90/10). Mix and package in heavy paper cartons with plenty of paper packing to serve as fuel. Burn in an incinerator.
2 Mix with a flammable solvent and spray into a firebox of an incinerator equipped with an afterburner and scrubber.
Destruction by chemical decomposition is recommended for dinitro, trinitro and other compounds with explosive potential. Add the material, slowly, while stirring, to 30 times its weight of a solution prepared by dissolving 1 part sodium sulphide in 6 parts water. For unstable acidic materials (eg. picric acid) dissolve in 25 times its weight in a solution from 1 part sodium hydroxide and 21 parts sodium sulphide in 200 parts water. Some hydrogen sulphide and ammonia is evolved.
