Isocyanates are hazardous chemicals that are used in the manufacturing of polyurethane foams, rubbers and plastics. They are also present in the use of varnishes, adhesives and paints.

Exposure to isocyanate groups may result in occupational asthma and other severe adverse health effects.  As such it is a legislative requirement that health monitoring be provided to exposed workers for occupational safety and health purposes.

Isocyanate health surveillance programs must be conducted under the supervision of a medical practitioner with experience in health monitoring.

A health monitoring program for workers exposed to isocyanates should involve:

  • A baseline health monitoring assessment at the commencement of employment
  • A periodic health monitoring assessment after six weeks of initial exposure
  • A periodic health monitoring assessment every six months (annually after 12 months should no adverse health effects be identified)
  • An exit health monitoring assessment at the termination of isocyanate exposure.

Work activities that require health monitoring due to isocyanate exposure include:

  • Manufacturing operations, e.g. manufacturing polyurethane foams, synthetic rubbers, plastics production, insulation making, furniture making and cores for foundry casting
  • Spray painting operations, e.g. spray painting and spraying of resins, lacquers and adhesives containing isocyanates
  • The use of varnishes, e.g. timber floor finishing
