6. Laboratory Safety
Students should not enter the laboratory unless a teacher (or laboratory technician) is present.
Students should follow teacher’s instructions strictly.
Students should not remove anything from the laboratory without permission.
Students should not rush around or play in the laboratory.
Students should return apparatus and chemicals to the appropriate places after used.
Students should report all accidents and breakages to their teachers.

7. Laboratory Safety (cont)
Eating, drinking and smoking are strictly forbidden in the laboratory.
Wear safety goggles in the laboratory whenever necessary.
Always read the label on a reagent bottle carefully before use.
Do not taste anything in the laboratory.
Always wash hands thoroughly after experiment.
Always tie up your long hair.

8. Common apparatus Add some water in a BEAKER.
Pour some water into a TEST TUBE.
Hold the test tube using a TEST TUBE HOLDER and shake it.
Pour some water into a MEASURING CYLINDER and read the volume.
Remove some water from the measuring cylinder with a DROPPER.

9. Prepare a solution Transfer some salt into a beaker using a SPATULA.
Add water to the 50 cm3 mark.
Stir the liquid with a GLASS ROD so as to dissolve the salt.
A clear solution is obtained.
