Safety
Eye protection should be worn.
Take special care when heating any sample. Make sure you heat only a small amount, over a heat proof surface. Handle hot things with care and ensure good ventilation. If you are in any doubt as to whether or not to heat something, do not heat it or check with your teacher first.
Be careful when testing things for hardness. You do not have to hit them very hard. Test only a small sample. A small tap with a hammer or blunt object is sufficient.
For substances from Group 4, except salt, you should wear disposable gloves and wash your hands thoroughly after handling.
