Check your batteries
By Mark van der Feyst
Most SCBAs have battery-powered components. These items can include the heads-up display, the chest gauge and the voice communicator. The lifespan of a battery can vary, but the common denominator is that the battery will fail.
Some SCBAs have low-battery indicators to alert us to change them; others do not. Be sure to check and change your batteries. It's better to waste batteries with some life left than what's left of your own life.
