Cardboard burning test
Hi guys! I have recently asked about some cardboard in the basement, and instead of making lab test i decided to burn piece of it. One piece flamed immediately, other did n't burned well, but finally turned into ash. So - does it prove that it was regular cardboard, not asbestos? Or i am superdumb and contaminated wholearea? video with burning https://drive.google.com/file/d/1ZbHGCFbWjrxyXJBNR7DEBKfCuaxzKdYa/view?usp=sharing
Also, what about other visible types of insulation? Grey stuff looks like damaged foam rubber. And also there is something looking like some fabric or even bandage - what is it?
