<reasoning>

Analyze individual statements regarding PPE

• Statement 1: PPE is used when engineering and administrative controls cannot reduce hazards to safe levels.
• Statement 2: Under the hierarchy of controls, PPE is positioned at the bottom as the final line of defense (last resource).
• Statement 3: Chemical PPE standardly consists of protective eyewear (goggles), hand protection (gloves), body protection (aprons), and respiratory protection (respirators).

Determine the correct option

• Since all three individual statements are factually correct, the option "All of the above" must be the correct choice.
