What is NOT a part of the criteria for checking a fire extinguisher?

A fire extinguisher is a critical piece of safety equipment, and conducting regular checks ensures it is ready for use in case of a fire. The criteria for checking a fire extinguisher typically include verifying that it is fully charged, located in a designated area, and free from visible damage.

The reference to "one-time use only" is not accurate in this context. Fire extinguishers can be used multiple times, and after each use, they should be recharged or replaced to ensure they are functional in future emergencies. This makes it clear that the notion of them being for one-time use is not aligned with the intended purpose of a fire extinguisher, which is to be a reusable safety device. Hence, identifying "one-time use only" as not being part of the criteria is correct.
