Chemical Safety in TB Lab Settings

Workers in microbiological laboratories are not only exposed to pathogenic microorganisms, but also to chemical hazards. Therefore, knowledge of the toxic effects of these chemicals, exposure routes and hazards, that may be associated with handling and storage, is important.

A few important general safety measures against chemical exposure in laboratories are:

1. Wear eyeglasses when using a chemical that can cause fumes or vapours.
2. Wear gloves at all times.
3. Wear lab coat all the time.
4. Do not eat in laboratories.
5. Tightly secure lids of all chemical bottles when not in use.
6. Read chemical cautions on the labels carefully for all chemicals before use.
7. Label the chemicals with appropriate icons to mark the potential risks (Figure).

Safety data sheets or other chemical hazard information are available from chemical manufacturers and/or suppliers. These should be part of the safety or operations manual and easily accessible.
