In what way do engineering controls differ from administrative controls?

The distinction between engineering controls and administrative controls is vital in understanding workplace safety and health practices. Engineering controls involve implementing physical modifications to the workplace or processes that are designed to eliminate or reduce exposure to hazards. These modifications can include installing ventilation systems, using safety guards on machinery, or redesigning equipment to minimize risks. Essentially, engineering controls focus on changing the work environment itself to protect workers.

On the other hand, administrative controls are centered around policies, procedures, and practices aimed at managing how work is conducted. This includes training workers, scheduling shifts to limit exposure time, creating safe work practices, and establishing safety protocols. Administrative controls do not inherently change the physical work environment but rather change how workers interact with it.

Thus, the correct answer accurately reflects the fundamental difference: engineering controls involve physical modifications to reduce exposure, while administrative controls rely on policies and procedures to manage risks.
