Working Safely in Science

Scientists working in the field, or in a laboratory, like those in Figure 10, are trained to use safe procedures when carrying out investigations. Laboratory work may involve flames or hot plates, electricity, chemicals, hot liquids, sharp instruments, and breakable glassware.

Whenever you work in your science laboratory, it's important for you to follow safety precautions at all times. Before performing any activity in this course, study the rules in the Science Safety section of the Skills Handbook. Before you start any activity, read all the steps. Make sure that you understand the entire procedure, especially any safety precautions that must be followed.

The single most important rule for your safety is simple: Always follow your teacher's instructions and the textbook directions exactly. If you are in doubt about any step in an activity, always ask your teacher for an explanation. Because you may be in contact with chemicals you cannot see, it is essential that you wash your hands thoroughly after every scientific activity. Remember, you share responsibility for your own safety and that of your teacher and classmates.
