What level of PPE is required for a confirmed airborne hazard and why?

• A. Level B; provides protective clothing for splash and contact exposure.
• B. Level C; provides basic respiratory protection.
• C. Level A; provides full encapsulation and respirator protection from vapors.
• D. Level D; provides nothing beyond basic safety.

Answer: (C)

Airborne hazards demand protection that blocks both inhalation of vapors and skin contact with toxic agents. The highest level of PPE provides full encapsulation plus a self-contained breathing apparatus, creating a sealed barrier around the worker and supplying independent air. This Level A ensemble prevents vapors from reaching skin or eyes and protects the lungs from inhalation, which is essential when the atmosphere is known to be contaminated with hazardous vapors or gases. Other levels either leave skin exposed (Level B), rely on air-purifying respirators (Level C) that don’t offer full encapsulation, or provide only basic work clothing (Level D). So for a confirmed airborne hazard, Level A is required to ensure maximum protection.
