What characteristic enhances the effectiveness of Personal Protective Equipment (PPE) while also making it more uncomfortable to wear?

The effectiveness of Personal Protective Equipment (PPE) is greatly influenced by the material's resistance to penetration. This characteristic is crucial for ensuring that hazardous substances, such as chemicals or biological agents, do not breach the protective barrier that the PPE provides. When a material is highly resistant to penetration, it effectively safeguards the wearer from harmful exposures, making it a fundamental quality for PPE used in environments where such risks are present.

However, materials designed with high resistance to penetration often sacrifice comfort in terms of breathability and weight. For example, while a thicker or more robust material may enhance protective qualities, it can also lead to increased heat retention and reduced airflow, making the PPE feel hotter and heavier during use. This discomfort can discourage proper use, thus impacting the overall safety of the individual relying on that equipment.

In contrast, characteristics like airflow allow for increased comfort but can diminish the protective capacity against certain hazards. Similarly, while weight can indeed affect the wearer's comfort level, heavier materials are often structured for maximum protection, thus creating a trade-off between comfort and safety. Color generally does not impact the protective capabilities of PPE but may provide visibility or identification benefits in certain settings. Therefore, the characteristic that truly enhances protective effectiveness while introducing discomfort is the material's resistance
