Handle all glass material carefully. Breakages are dangerous and may result in losing important materials.
Place flasks and beakers on a gauze mat or wire gauze when heating over a Bunsen burner flame.
When diluting concentrated acids, use thin-walled glassware since the heat evolved by the procedure often cracks thick glassware.
Number containers and their corresponding ground glass stoppers to ensure direct matching when you replace the stopper.
All chemicals should be well labelled and stored in the right place using proper containers.
Handling of the Bunsen Burner.
Always turn off the Bunsen burner after use.
Always make sure that flammable liquids and combustible materials are not near the Bunsen burner to avoid the risk of unwanted fires and explosions.
When lighting the gas, have your strikers ready to avoid excess gas leakage that might lead to an explosion.
Once you are done with the Bunsen burner, it is critical to turn off the main gas valve to avoid leakages.
The burner should cool completely after use before any further handling.
Handling a light microscope.
Always use both hands when carrying a light microscope.
Do not place a light microscope on the edge of a bench or table as it may fall.
Do not place specimens directly on the stage of a light microscope. Always place them on a microscope slide and cover them with a cover slip.
Always use a lens tissue to cleans the lenses. Hard materials are likely to scratch the lenses.
Ensure that the low power lens is in position before storing the microscope.
Always dust the microscope using a soft cloth, for example linen
