Fire extinguishers should be inspected:

A) Annually

B) Bi-Annually

C) Monthly

D) Daily

It all depends on which type of inspection they are talking about.

- A visual inspection is recommended Monthly.

- A maintenance inspection is recommended Annually.

So, if I was the one who had this question, I would put C) Monthly. As monthly checks are recommended by many websites that I saw.

You have to check monthly to insure that the extinguishers is in good working order. If not then replace it.
