I've also been talking to two friends on a fanfic list who have relatives who are retired firefighters, and I've gotten some conflicting information. I realize that it might be that the technology has improved since these people were on active duty.
Basically, one friend tells me that firefighters are trained to search a room sightlessly because the smoke and flames would obscure their vision, BUT that night-vision goggles would work if they weren't so expensive. Infra-red would blind the wearer in a fire.
The other friend tells me it's the night-vision goggles that would be blinding and "heat-vision goggles" would be best. Is this the same as infra-red?
What's the correct answer?
Note: I should mention that this is a Batman fanfiction and the goggles would be "bat" equipment. I want them to be something available with existing technology, but since we're dealing with the Wayne fortune, the expense is irrelevant. So if night-vision is technologically superior but would cost too much to be standard gear, that's not a concern.
