What symptom might a worker experience when exposed to excessive mold growth in the supply air plenum?

1. Blurred vision

2. Anaphylactic shock

3. Allergic rhinitis

4. Chest pain

The correct answer is: Allergic rhinitis

When workers are exposed to excessive mold growth in the supply air plenum, one common symptom they may experience is allergic rhinitis. This condition, often referred to as hay fever, is triggered by allergens such as mold spores, leading to symptoms like sneezing, runny or congested nose, itchy eyes, and throat irritation. The presence of mold can significantly impact indoor air quality, exacerbating allergies and respiratory conditions. Allergic rhinitis occurs due to the immune system's response to mold allergens, making it a prevalent issue in environments where mold is significant. In contrast, while blurred vision, anaphylactic shock, and chest pain can occur in various health-related contexts, they are less commonly associated specifically with mold exposure and do not represent the typical symptoms seen in many cases of allergic reactions to airborne mold particles.
