(1) Engineering Controls, where feasible, are the preferred method for controlling WMSD hazards. Engineering controls are the physical changes to jobs that control exposure to WMSD hazards. Engineering controls act on the source of the hazard and control employee exposure to the hazard without relying on the employee to take self-protective action or intervention. Examples of engineering controls for WMSD hazards include changing, modifying or redesigning the following:
Workstations
Tools
Equipment
Materials
Processes
(2) Work Practice Controls are controls that reduce the likelihood of exposure to WMSD hazards through alteration of the manner in which a job or physical work activities are performed. Work practice controls also act on the source of the hazard. However, instead of physical changes to the workstation or equipment, the protection work practice controls provide is based upon the behavior of managers, supervisors and Employee(s) to follow proper work methods. Work practice controls include procedures for safe and proper work that are understood and followed by managers, supervisors and Employee(s). Examples of work practice controls for WMSD hazards include:
