Ventilation – Local. Other – Handle in accordance with good industrial hygiene and safety practice.

Ecological Information : Well eliminable from water by absorption on activated sludge. The product is not very soluble in water and can thus be removed from water mechanically in suitable effluent treatment plants. Other adverse effects – Absorbable organically-bound halogen (AOX): 2.5%. This product contains according to the formulation, organically bound halogen. It can increase the AOX-value in the water purification plants overflow or if it reaches waters. The product contains: 8,8 W /W% copper. The heavy metals are present in complex bound form as substantial constituent of the colorant. The inhibition of the degradation activity of activated sludge is not anticipated when introduced to biological treatment plants in appropriate low concentrations.
