SAWS
deep cuts, such as in walls, a chain saw or Cut-n-Break would be better to use than a typical power cutter.
The type of material also will establish what type of blade to use. If the proper blade is not used for the material to be cut, safety hazards increase, and the power cutter potentially can perform poorly and lose productivity.
Dust and debris.
If the indoor area is not properly ventilated, dust can accumulate in the space and can be hazardous to the operator.
Dust and debris can make it difficult to see if it accumulates in the area for a long period. It also is dangerous to the operator's health if inhaled for an extended amount of time.
If the area to be cut has poor air flow and dust/debris needs to be controlled, the best tool to use would be an electric power cutter, due to the fact that it is lightweight and can be used either wet or dry. However, how safe is it to use an electric power cutter, especially if the contractor is going to cut wet?

An electric power cutter specifically designed to cut wet will have a GFCI or Ground-Fault Circuit Interrupter installed to help protect the user if there is damage to the electric circuit. Saws intended to cut with water are designed in a way to protect the electrical components from water that would otherwise interfere with safe operation of the power cutter. Power cutters that are intended to cut with water have special
