Operation

Spraying a liquid nanodispersion

Potential Risk

Spraying the liquid dispersion will result in aerosolization of the dispersion into small droplets that have the potential for inhalation, dermal and eye contact.

Controls

• Ventilated spraying & process equipment
• The ventilation exhaust must be processed with HEPA* exhaust filtration
• When exhaust ventilation is not feasible, PPE shall be utilized to prevent potential inhalation, dermal and eye contact with the aerosolized dispersion
• Latex or nitrile clean room gloves
• Wet cleaning methods when cleaning equipment

Note: Additional PPE and or EHS controls may be required based on the suspension solvent selection

Alternatively, Control Banding may be employed when more is known about material reactivity, exposure duration and material state.
