Wear goggles and a laboratory apron

Hold the test tube with a test tube clamp not in your bare hand.

If the liquid is nonflammable it may be heated in the flame of a Bunsen burner, otherwise a hot water bath over a hot plate may be more advisable.

If heating in the flame of a Bunsen burner hold the test tube at an angle and move the tube in and out of the cool area of the flame.

Alway point the opening of the test tube AWAY from yourself and others.

Does Liquid nitrogen explode with heat?

Liquid nitrogen expands rapidly when heated, which can lead to a pressure build-up. If contained in a sealed container, this pressure can cause the container to rupture explosively. Liquid nitrogen itself does not explode when heated, but the rapid expansion can lead to potential safety hazards.
