Activity 6: Hot Work
Sparks and slag can scatter throughout an area where hot work is going on — sometimes up to 35 feet or more. Sparks and slag can also pass through cracks, gratings, doors, drains, open hatches and other openings in walls, floors or vessels, creating fire/explosion hazards in sometimes distant areas.

Slag Driveway Pros and Cons
Slag has a great appearance and is a low-cost alternative that conserves the environment. A slag driveway has higher strength and better adhesion, making it more durable than most materials. On the other hand, the limitations of slag are; that it's expensive to acquire, it can be toxic, and it has a high swelling potential. What is a slag ...
