Which PPE item is identified as the final control option?

• A. Gown - long sleeved and water resistant.
• B. Gloves - cytotoxic resistant.
• C. Splash guard and maybe goggles.
• D. PPE (final control option).

Answer: (D)

The idea being tested is where PPE sits in the hierarchy of hazard controls. PPE is the final line of defense—the last control option—used when other measures (like eliminating the hazard, engineering controls such as splash guards, or administrative procedures) have reduced risk as far as possible but not completely. In practice, you first try to remove or isolate the hazard and put barriers in place; if that doesn’t bring exposure down to an acceptable level, you add PPE to protect the worker directly.

So identifying PPE as the final control option makes sense: it represents the protective layer worn by the person, used after all higher-level controls have been implemented. The other items listed are specific protective pieces (like a gown or gloves) or combinations that include a barrier (such as a splash guard) plus PPE, but the concept the question targets is PPE as the last safeguard protecting the wearer.
