Control tables reduce the need for programming similar structures or program statements over and over again. The two-dimensional nature of most tables makes them ...
Engineering controls is the third of five members of the hierarchy of hazard controls, which orders control strategies by their feasibility and effectiveness. Engineering controls are preferred over administrative controls and personal protective equipment (PPE) because they are designed to remove the hazard at the source, before it comes in ...
