Answer:

Standard safety precessions

Explanation:

The students should be required to pass a standard safety quiz before being allowed to participate in chemical experiments.

The standard safety requirements for heating are

  1. Always wear safety glasses.

  2. Always point the test tube away from any other person in the lab.

  3. Heat the test tube being held at an angle so there is a way for the gases produced to escape safely.

  4. Heat the test tube at the top of the solution not the bottom where a gas bubble can cause an explosion.

  5. Heat the test tube gently moving the heat away as the solution begins to boil.
