Which of the following is NOT a symptom of chlorine inhalation?

Inhalation of chlorine gas can produce a variety of symptoms due to its irritant properties. Symptoms commonly associated with chlorine inhalation include coughing, which is a reflex response to irritation of the respiratory tract, ocular irritation as the gas can affect the eyes, and severe chest pain, which may occur from damage to lung tissue or heightened respiratory distress.

Fatigue, while it may occur in the aftermath of exposure or reaction to other symptoms, is not directly recognized as an immediate symptom of chlorine inhalation. Instead, the acute effects of chlorine gas are more prominently characterized by the respiratory and ocular symptoms listed. Thus, fatigue stands out as not being a primary, immediate symptom associated with chlorine exposure. Understanding these clinical manifestations helps in managing and treating patients who have encountered chlorine inhalation effectively.
