Exposure to Asbestos,..however small, does carry a threat,....not now, not 5 years from now...more like 30 years, but the threat is there...you obviously have a concern...or you would,nt be asking....as to whether this fireproofing material thats within the walls of the safe..is Asbestos...i can,t say, but..if it was...how did it leak out from within the sealed walls of the safe....is there a hole/crack.or any aperture from,whence it came....
