B8.3 Storage of Hazardous Materials



Hazardous materials include:

  • Substances used directly in work activities (e.g. adhesives, paints, cleaning agents).
  • Substances generated during work activities (e.g. fumes from soldering and welding).
  • Naturally occurring substances (e.g. grain dust).
  • Biological agents such as bacteria and other micro-organisms.


Hazardous substances may be found in almost all environments, including factories, farms, shops, laboratories and offices.

  • Skin irritation or dermatitis as a result of skin contact.
  • Asthma as a result of developing allergy to substances used at work.
