Answer:

D

Step-by-step explanation:

Solution

A: You have to alert someone if there is glass on the floor. Consider the kind of shoes that most people wear. It would be a disaster to be cut by something that had contained a chemical. The action is true and therefore A is not the answer.

B: You always replace any glass wear that is cracked. What if it breaks, then what. The answer is a correct answer, and therefore you would not pick B.

C: You always treat fire with care. It's not C.

D: I don't know about you, but I'd be awfully careful about putting my mouth over something that I'm not sure what it would do if I accidently swallowed the contents of the pipette. D is not a good procedure, but it is the answer.
