In handling a burner or alcohol, you must better use gloves to avoid burns that may happen accidentally in your laboratory experiment.Don't be so importunate like walking or running around while your performing your activity.Lastly,let it cool first before you move them.
In handling the platform balance or the thermometer, it is common that the person who performs the activity must focus on what their doing....(I'm not sure about this)
