There are many hazards associated with working in glass, but very few schools are likely to use the material extensively.

7.4.1    Batch Mixing and Loading
7.4.2    Hot Glass
7.4.3    Cutting, Grinding and Polishing

7.4.1    Batch Mixing and Loading

In batch mixing and loading in which silicaceous and toxic dusts are likely to be created, a batch must always be mixed in a sealed container and all appropriate safety measures must be observed.

7.4.2   Hot Glass

When working with hot glass, eye protection, protective clothing, safety spectacles and other appropriate personal protection precautions must be used. Kilns are subject to the same regulations and safety procedures as for ceramics kilns.

7.4.3    Cutting, Grinding and Polishing

Precautions should include the use of personal protective clothing, eye shields and glasses. Grinding wheels must be run at the appropriate settings for 'trueness' and wheel speeds, and enough water should be used to ensure coolness and remove waste.

Handling lead can result in particles being trapped under fingernails or accidentally ingested. Hands should be thoroughly washed and fingernails scrubbed, and care taken to keep hands away from the mouth when working.
