Which body system is primarily affected by OC spray?

• A. The eyes and respiratory tract
• B. The digestive system
• C. The circulatory system
• D. The nervous system

Answer: (A)

OC spray primarily targets the eyes and the upper airway. When exposure happens, the capsaicinoids irritate the mucous membranes, triggering an immediate burning sensation, tearing, redness, and swelling of the eyes, which often makes it hard to keep them open or see. At the same time, the irritation reaches the nose and throat and inflames the airway, leading to coughing, a choking feeling, runny nose, and sometimes breathing difficulties. This combination of reflexive eye closure and airway irritation is what makes OC spray effective for temporary incapacitation. While there can be discomfort elsewhere with higher exposure, the digestive, circulatory, and nervous systems aren’t the primary targets; the eyes and respiratory tract are the most sensitive and quickest-responding areas.
