What is a common sign of chemical exposure?

A common sign of chemical exposure is skin irritation or respiratory issues. These symptoms are closely linked to the body’s reaction to harmful substances encountered through inhalation, skin contact, or ingestion.

Skin irritation can manifest as redness, rash, or burning sensations in areas that came into contact with chemicals, indicating that the skin is reacting adversely to potentially harmful compounds. Respiratory issues may include coughing, wheezing, or difficulty breathing, which signify a negative reaction to inhaled chemicals, highlighting the urgency for further medical evaluation or removal from the environment where exposure occurred.

The other options do not typically indicate chemical exposure. Loss of appetite, while potentially a symptom of various conditions, is not specific to chemical exposure. Increased productivity typically reflects a positive response to working conditions and does not align with the adverse effects of chemical exposure. Excessive sweating can have several causes, such as heat or anxiety, but is not a definitive sign of chemical exposure. Thus, the clear and direct signs of irritation or respiratory issues are why this option is correct.
