Solution
The answer is: Personal protective equipment.
Explanation for each option:
Substitution: This control method involves replacing a hazardous material or process with a less hazardous one. It is a proactive measure and not considered the last line of defense.
Administration: Administrative controls involve changing the way people work, such as implementing new policies, procedures, or training programs. These are also not the last line of defense but rather intermediate measures.
Engineering: Engineering controls involve isolating people from the hazard, such as using ventilation systems or machine guards. These are designed to remove the hazard at the source and are not the last line of defense.
Personal protective equipment (PPE): PPE includes items like gloves, masks, and safety glasses that workers wear to protect themselves from hazards. PPE is considered the last line of defense because it does not eliminate the hazard but rather minimizes exposure to it when other controls are not sufficient.
Therefore, the correct answer is Personal protective equipment, as it is used as the last line of defense to minimize exposure to a risk.
