Isocyanates are now a cause of chemical safety concerns. They are classified as hazardous substances and can cause sensitisation.

Their applications and handling methods are a major factor in deciding how users should protect themselves from such hazards. Some knowledge is required in order to use isocyanates safely - to protect yourself, observe a few rules of thumb.

  1. Remember to ensure effective and appropriate ventilation.
  2. Protect your skin and eyes from spatters.
  3. Employer: If you are unsure about exposure levels in the workplace, measure them!
