Chemicals are part of our daily life. Virtually every manufactured product involves the use of chemicals. Many chemicals can significantly contribute to the improvement of our quality of life, health and well-being, when properly used. However when improperly handled, can negatively affect our health and environment.

The use of chemicals continues to grow in Uganda. This is likely to result in greater negative effect on health if sound chemicals management is not ensured. Therefore, action is urgently needed from the government, employers and the public, to protect human health from the harmful effects of improperly managed chemicals.

The chemical inventory here is a one-stop shop for occupational chemical information suitably designed for emergency responders, first aiders, chemical users including employers, farmers and the general public. It compiles information from several international agencies and organizations such as OSHA, NIOSH, WHO, CDC. Information available here includes:

  • Chemical identification
  • Associated major hazards
  • Exposure limits
  • Safety Data Sheets
  • Regulatory obligation and
