(2) In property insurance, this term refers to a situation where there is a mixture of covered and uncovered perils acting together (either in sequence or simultaneously) to produce the same property damage.
Drywall is relatively fireproof, but manufacturing processes such as adding glass fibers can increase the resistance. Drywall is relatively fire resistant. It's composed of gypsum pressed between two sheets of thick paper. Gypsum is a soft mineral that by itself is not flammable. Additionally, water is incorporated into its structure. In the presence of fire, heat energy vaporizes the water, removing it gradually. Water effectively blocks the transfer of heat through the drywall.
A restriction in the venting can cause lint to build-upinside the dryer where it is a very real fire hazard! Between 1980-1998 an average of 14,500 fires * per year * are known to have been the result of dryers. Those fires average 13 deaths, 239 injuries and $53.1 million in property damage * per year *.n a properly installed vent, any lint that escapes the dryer's lint filter should be blown right outdoors. Any accumulation which occurs inside a dryer's ducting is usually a sign of poor air flow, especially near the location(s) it occurs.
