How do a fit test and a seal check differ for respirators?

• A. A fit test measures battery life under exercise conditions.
• B. A seal check verifies airtight seal before each use.
• C. A fit test assesses fit under training conditions; a seal check verifies airtight seal before each use.
• D. A fit test is optional and can be skipped.

Answer: (C)

The main idea is that fit testing and seal checks serve different purposes and happen at different times. A fit test is a formal assessment done in a controlled setting to see whether a specific respirator model fits the user across a range of movements and activities. It’s about judging overall compatibility and seal quality under conditions that simulate real use and is typically done periodically or when a new model or facial change occurs. A seal check, on the other hand, is a quick, pre-use check to confirm that the respirator is seated properly and there are no obvious leaks for that particular session. It doesn’t evaluate fit across multiple movements or over time; it just verifies the immediate seal before use. So the statement that best fits is that a fit test assesses fit under training conditions, while a seal check verifies an airtight seal before each use. The other options describe unrelated or incomplete ideas.
