Tetrasodium 2,2''-diamino-8,8''-dihydroxy-4',4'''-{4-[bis(2-hydroxyethyl)amino]-1,3,5-triazine-2,6-diyldiimino}bis(naphthalene-1-azobenzene-2',6-disulfonate)

Guidance on Safe Use

First-aid measures

Emergency measure - Inhalation: Move exposed person to fresh air. In case of indisposition seek medical advice.
Emergency measure - Eyes: Rinse with plenty of water and seek medical advice.
Emergency measure - Skin: Wash with soap and water.
Emergency measure - Ingestion: Symptomatic treatment. In case of indisposition seek

medical advice.

Fire-fighting measures

Recommended extinguishing agent: Water, dry powder, foam, carbon dioxide.
Product arising from burning: Combustion products may contain carbon, nitrogen oxydes and other derivatives.
Protective equipment: Wear self-contained breathing apparatus.

Accidental release measures

Emergency measures in case of spillage: Wear protective clothing (dust mask, safety goggles and impermeable gloves).
Solids: Sweep up (wet powders with water) and place in suitable containers for disposal.
Liquids: Absorb using an adequate absorbent (eg. kiesel- gur, sand, saw dust, kieselgel), collect and place in suitable containers for disposal.
Dispose of waste material in authorised incineration facility.

Handling and storage

Handling: Observe the usual precautions for handling chemicals. If the pure substance is handled as powder, avoid inhalation of dust and wear dust mask. Use equipment for handling powders or other appropriate engineering controls.
Avoid eye and skin contact and wear safety goggles and impermeable gloves.
Take precautionary measures against static charges.
Storage: The substance should be stored in well sealed and secure containers in adequate rooms at room temperature.
Avoid residues outside the containers.
Packaging of the substance and or preparation: The commercial preparation is supplied in 60-l and 1000-l containers.

SpecialProvisions

Exposure controls / personal protection

In case of inadequate ventilation wear respiratory protection.
Avoid contact with eyes.
Ensure adequate ventilation.
Do not empty into drains.
Do not dispose of waste into sewer.
Take up as such and consider recycling.

Stability and reactivity

Danger other than fire: Not known.
Chemical reaction with water: No dangerous reaction with water.
Dust explosion: Not to be expected if handled under good industrial hygiene practices.
The dyestuff preparation will be marketed in a dust-free sales form.

Dust explosion determined by test: N

Disposal considerations

Industry - Possibility of recovery/recycling: Normal application results in a high consumption of the dyestuff (approx. 99%) by irreversible binding to the paper fibres. Therefore, recovery/recycling of the substance is not possible.
Industry - Possibility of neutralisation: Not applicable.
Industry - Possibility of destruction: controlled discharge: Not suitable for deposit in landfill site.
Industry - Possibility of destruction - incineration: Code 661: Incinerator with flue gas scrubbing.
Industry - Possibility of destruction - water purification: Code 641: Removal by controlled discharge to a waste water treatment plant.
It is estimated that approx. 1% of the total quantity used is discharged into internal industrial effluents as highly diluted solution.
A purification of the waste water in a waste water treatment plant is recommended.
The dyestuff should be used in a well equiped dye house.
If necessary, the waster water can be purified prior to the waste water treatment by membrane filtration or by floculation with cationic agents or by treatment with ozone. The most effective method is the membrane filtration: more than 99% of the remaining dyestuff can be removed from the waste water.
Industry - Possibility of destruction - other: None.
Public at large - Possibility of recovery/recycling: Not applicable.
Public at large - Possibility of neutralisation: Not applicable.
Public at large - Possibility of destruction: controlled discharge: Not applicable.
Public at large - Possibility of destruction - incineration: Not applicable.
Public at large - Possibility of destruction - water purification: Not applicable.
Public at large - Possibility of destruction - others: Not applicable.
