What common symptom may indicate exposure to hazardous gas during capping?

1. Dry throat

2. Dehydration

3. Irritation of the eyes

4. Runny nose

The correct answer is: Irritation of the eyes

Irritation of the eyes is a common symptom that indicates exposure to hazardous gas during capping. This reaction occurs because many hazardous gases can irritate mucous membranes, leading to inflammation and discomfort in the eyes. When exposed to these gases, the body often reacts by producing tears in an effort to flush out the irritant, which is why eye irritation is a notable sign of potential exposure. In environments where capping concrete samples is performed, awareness of such symptoms is critical for ensuring safety and taking necessary precautions against exposure. The other symptoms, such as dry throat, dehydration, and runny nose, may be related to various other conditions or irritants, but eye irritation is particularly characteristic of an immediate response to hazardous gas exposure.
