Guidance on Safe Use
Administrative data
First-aid measures
• Inhalation: Seek medical advice, if the person inhales large amounts of dust. Workers having respiratory diseases should not handle reactive dyes. If there are any complaints in connection with handling reactive dyes such as shortness of breath or asthma, seek medical advice.
• Eyes: Rinse immediately with plenty of water in order to avoid discolouring of the eye; if necessary seek medical advice.
• Skin: Wash immediately with plenty of water and soap.
• Ingestion: Drink plenty of water, if necessary with added activated charcoal. If the person feels unwell, seek medical advice.
Fire-fighting measures
• Recommended extinguishing agent: Water spray, fog, foam, dry extinguishing agent and CO2. Do not use water-jet.
• Product arising from burning: H2O, COx, NOx, SOx.
• Product determined by test: N.
• Protective equipment: Protection suit and respirator (dependent on the extent of fire and the local surroundings).
Accidental release measures
• Skin contact and inhalation of dust and dye solutions should be avoided while accidentally spilt material is collected.
• Persons performing appropriate cleaning are advised to observe the protective measures prescribed for handling of the substance.
• In the event of spilling granulated product, dust generation is best avoided by covering with moistened inert material in order to avoid formation of dust.
• Dye solutions should be taken up with an appropriate absorbing material.
• Use an approved industrial vacuum cleaner with an appropriate absorbing material.
• Label waste containers accordingly and sent for disposal via a licensed waste contractor.
Handling and storage
• Handling: Avoid formation of dust. Store separate from food, tobacco and alcohol. Wear suitable protection clothes, gloves and goggles if skin or eye contact is possible. Change spoiled clothes. It is recommended that users observe the measures mentioned in "Guidelines for the safe handling of dyestuff in colour storerooms" from ETAD.
• Use local ventilation. Use personal protective equipment. If necessary, wear dust mask suitable for prevention of dust exposure. Avoid skin contact.
• Persons with chronic respiration diseases should not handle reactive dyes. If there are any complaints such as shortness of breath or asthma in connection with the handling of reactive dyes, seek medical advice. Avoid any contact with the dye in such cases.
• Storage: Store dry and at room temperature in tightly closed containers. Keep store rooms according to principles of good industrial hygiene. Close broken containers tightly. Avoid residues on/at containers.
• Packaging of the substance and/or preparation: Cardboard boxes: (25 kg).

Exposure controls / personal protection
• The substance is not classified for hazardous effects, and as such, no hazards to either man or the environment are predicted. Standard risk management measures should be applied during use of the substance and products containing the substance. The following Risk Management Measures are therefore recommended to facilitate good hygiene standards:
- Local Exhaust Ventilation, where available,
- Hand protection, such as chemically resistant gloves ( e.g. PVC or nitrile rubber (EN374)),
- Protective clothing to EN368 standard are minimum,
- Eye protection - safety glasses with side-shields (frame goggles) (e.g. EN166),
- Respiratory protection with 95% reduction of inhaled substance when handling material that may generate dust (e.g. EN149).
Stability and reactivity
• Danger other than fire: No risks are assumed for handling the substance.
• Chemical reaction with water: Slow hydrolysis of the reaction component.
• Dust explosion: The preparations are dust-poor granulates or liquid preparations. In the production process, only solutions are used.
• Dust explosion determined by test: N.
Disposal considerations
• Industry - Possibility of recovery/recycling: Recycling of used dyes is not possible. Wash waters from the dye process is recycled to minimise loss of product.
• Industry - Possibility of neutralisation: Code 631 - Neutralisation with acid-treatment.
• Industry - Possibility of destruction: control discharge: Disposal is possible on seepage-proof waste disposal site in accordance with local regulations.
• Industry - Possibility of destruction: incineration: Incineration of dry dyes is possible. Common waste gases arise during the incineration. Incineration should be undertaken in compliance with associated legislation.
• Industry - Possibility of destruction: water purification: Organic dyes are not biodegradable (aerobic) because of the short retention time. A dispose byDisposal via the waste water should not be recommended. Also, an accumulation at thein sewage sludge is possible. Wastes from sewage plant processing should be incinerated.
• Public at large - Possibility of recovery/recycling: The substance is not available to the public at large if it is used as intended. Only products dyed with the substance are available to the public at large.
• Public at large - Possibility of neutralisation: Not applicable.
• Public at large - Possibility of destruction: controlled discharge: The coloured products containing the substance only in little amounts could be disposed with the house waste onto a licensed disposal site or better by incineration.
• Public at large - Possibility of destruction: incineration: As above.
• Public at large - Possibility of destruction: water purification: Not applicable.
• Public at large - Possibility of destruction: others: Not applicable.
