  • Never work alone when using this substance.
  • Ensure someone can see or hear you.

Sermonic Example:

There are substances in this world, that when you read the precautions, reveal how dangerous they are.  The precautions alert you to the dangerous nature of the substance.  Sometimes it is a prescription that lists all the possible side-effects.  At other times it is a warning sign about the presence of something, “Do Not Enter Without Protective Equipment.”  Sometimes, the list of precautions one must take in handling a substance says it all . . . .

Here are some of the precautions indicated for handling a particular substance . . . .

(use whatever information and details you might find useful)

Those are the precautions that one must take when handling a pyrophoric substance.  A pyrophoric substance is one that will ignite spontaneously if exposed to air or water.

Just look at the warnings, the precautions, the admonitions and you can tell it is dangerous and how dangerous it is to experiment with it.

The book of Proverbs gives us warnings, admonitions, and precautions about three areas of life — sexual promiscuity, laziness, and foolish companions. . . . .
