Thus, it is very important to wipe off tar stains on clothes or even rags just the same way you would do with gas spills. This is because it is only a matter of time before a burning cloth spreads fire in the entire house.

Typically, tar has high viscosity (relatively thick). And when you subject this fluid to a specific hot temperature, it undergoes some changes.

First, tar becomes less viscous and because of this, it flows faster along a narrow tube or container. Then, it develops foams and gradually rises to the tip of this container.

Thereafter, the overfilled tar container will shed off some drops of tar on its sides or the floor. So, if the accumulated drops of tar on the floor come in contact with another fire source, it will be only a matter of time before the tar ignites.

Why Is Burning Tar Always Sticky?
