6 Risk Assessment and Management of Chemical Products
• The uncertainty is relatively high as many extrapolation steps had to be made.
• The assessment factor of 1000, however, is relatively conservative and may
compensate for this uncertainty.
6.8.5 Risk Management (Step 5)
To reduce the risk of adverse effects on the employees, safety measures could be
considered to reduce exposure to the dye, including:
• Using a liquid formulation of the dye or a formulation as low-dust granules
• Applying closed handling processes during dyeing
• Improving building ventilation
• Using personal protective equipment
To reduce the risk of adverse effects on the environment, risk reduction measures
that could be considered include:
• Minimizing residues of the dye in the dyeing liquor, e.g., by maximum extraction
• Adsorption to activated carbon
• Concentrating and desalinating the wastewater using reverse osmosis
While these risk reduction options focus on minimizing exposure, an alternative dye
could also be sought that has reduced inherent hazardous properties.
