COSHH Assessment — Optical Instrument Cleaner (Triethanolamine / TEA Aqueous Solution)

This pre-completed COSHH assessment covers optical instrument cleaner based on triethanolamine (TEA) — a mildly alkaline aqueous solution used for cleaning precision optical surfaces including lenses, prisms and coated glass in laboratory, medical and scientific instrument settings.

What Does This COSHH Assessment Cover?

The assessment is fully completed and ready to use, covering all sections required for a complete hazardous substance risk assessment:

  • Substance identification — trade name, chemical name (TEA-based aqueous surfactant blend), SDS reference and physical state
  • Health effects and first aid — inhalation, ingestion, skin contact and eye contact, with specific first aid for each route
  • Alkaline contact hazard — mildly alkaline formulation (pH 8–10); prolonged skin contact and eye exposure can cause irritation beyond mild effects
  • Workplace exposure limits — TEA TWA and guidance on ventilation for regular use
  • CLP hazard classification — Irritant and Corrosive pictograms
  • PPE requirements — including eye protection and chemical-resistant gloves
  • Emergency procedures — spillage and fire response
