How can humidity affect SCBA usage?

High humidity can indeed lead to condensation inside the facepiece of an SCBA, which can significantly reduce visibility for the user. When the air is saturated with moisture, any breath that is exhaled can lead to water vapor condensing on the cooler surfaces of the facepiece, creating fog or droplets that obstruct vision. This can be particularly dangerous in emergency situations where clear sight is crucial. Ensuring that SCBA equipment is designed to minimize this effect and that users are aware of potential visibility challenges in humid conditions is essential for maintaining safety and effective operation during use.
