What is the main drawback of cartridge respirators?

1. High cost of replacement parts

2. Limited visibility for the wearer

3. Leakage around the face shield

4. Poor filtration effectiveness

The correct answer is: Leakage around the face shield

Cartridge respirators are designed to protect wearers from inhaling hazardous substances in the air, utilizing filters or cartridges that capture specific pollutants. One of the key issues associated with these types of respirators is the potential for leakage around the face seal. Proper fit is crucial for ensuring the respirator functions as intended, but any gap or misalignment can allow contaminated air to enter, undermining the protection provided. This concern about leakage emphasizes the importance of proper fitting instructions and regular checks to ensure that the respirator creates a secure seal on the wearer's face. Unlike the other potential drawbacks, such as high costs or visibility issues, which may vary based on specific models and situations, leakage around the face shield is a fundamental concern linked to the functionality and efficacy of the respirator itself. Thus, ensuring a tight seal is vital for maximum protection against inhaled hazards.
