Which type of emitters should be inspected on both sides of the power module?

The correct answer pertains to piezo emitters, which are known for their ability to produce sound or vibrations through the piezoelectric effect. Inspecting them on both sides of the power module is crucial because these emitters rely on mechanical properties for their operation, and any damage or loose connections could affect performance. Additionally, a comprehensive inspection ensures that the entire emitter surface functions properly, as irregularities on either side can lead to inconsistent output or failures.

In the context of the other emitter types, laser emitters typically emit coherent light and may not require inspection from both sides since their functionality mainly depends on the optical path rather than mechanical integrity. Infrared emitters primarily focus on heat or light transmission and also may not necessitate dual inspections, as their operation is less affected by physical damage on both sides. LED emitters, while they do emit light in a directional manner, are generally designed for single-sided operational use and would not require inspection from both sides of the power module in the same capacity as piezo emitters.

Understanding the specific requirements and fault sensitivity of each emitter type is essential for effective maintenance of equipment utilizing the MSA G1 SCBA system.
