Operation

Machining polymer nanocomposites

Potential Risk

Machining solid polymer nanocomposites at high speed, could result in generation of nanocomposite particles or free nanoparticles

Controls

• Ventilated machining equipment (mechanical process, or agitation).
  • 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 exposure to nanocomposite particles.
• 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.
