Here's the dilemma: The fire marshal does not approve of the Class C fire rated Sonex polyurethane foam that lines our bat flight chamber. Sonex makes a ceramic based, Willtec foam that meets the Class A fire rating the marshal requires. This foam is naturally white. It would only take a few days for our bats to soil the foam and its likely that tracking our bats on film, illuminated in the infrared, would be compromised with a white background. So, the options are to buy foam painted or dyed a dark color.
Here are a few questions, but any thoughts would be appreciated: Does anyone have any experience with painted (latex or hypalon covered) foams reflective characteristics in the ultrasound range of 30-90 kHz? How have your Animal Care and Use Committees responded to painted or dyed acoustic foams? Toxicity? Thanks, Jesse Barber [EMAIL PROTECTED]
