Respirators are used to protect against inhaling which of the following?

• A. Soot and dust
• B. Chemicals, smoke, and vapors
• C. Cold air and moisture
• D. Carbon dioxide

Answer: (B)

Respirators are specifically designed to protect the wearer from inhaling harmful substances present in the air, including chemicals, smoke, and vapors. These substances can pose serious health risks when inhaled, leading to respiratory issues or long-term health problems. Respirators serve as a barrier, filtering out airborne contaminants before they can reach the lungs, which is crucial in environments where these harmful agents are present. While soot and dust can also be a concern for respiratory health, they are typically managed by different types of masks or filters rather than specifically classified as the primary purpose of respirators. Cold air and moisture do not constitute harmful inhalants in the same way chemicals or vapors do, hence would not be a focus for respirators. Similarly, carbon dioxide is a normal component of the atmosphere and is not typically filtered out by respiratory protection devices designed for industrial or medical use.
