Answer 1

An SCBA cylinder needs to be replaced when it is damaged or has exceeded its service life.

Step-by-step explanation:

The correct answer is 1) When the cylinder is damaged or has exceeded its service life. An SCBA cylinder, which stands for Self-Contained Breathing Apparatus, needs to be replaced if it is damaged or has reached the end of its service life. This is because a damaged cylinder may not be able to hold the high pressure of the compressed air, posing a safety risk to the user. Additionally, cylinders have a limited service life and need to be replaced according to the manufacturer's guidelines.
