How often does a person need to be fit tested for a respirator?

Every 6 months
Every year
Every 2 years
Every 3 years

The correct answer is: Every year

The recommended frequency of fit testing for respirators is annually. This requirement is based on guidelines set by occupational health and safety regulations, which emphasize ensuring that the respirator provides an adequate seal for the user. Factors that could affect the seal include weight fluctuations, facial changes due to aging, or dental work, all of which could affect the fit over time. Annual fit testing ensures that workers are protected against respiratory hazards throughout the year, as even small changes in facial structure can significantly impact the effectiveness of a respirator. Regular testing is essential to maintain a proper fit for safety and compliance with health regulations.
