Chemical Defense

Respiratory Exposure

Respiratory responses to OC spray include burning of the throat, wheezing, dry cough, shortness of breath, gagging, gasping, inability to breathe or speak, and, rarely, cyanosis, apnea, and respiratory arrest.

Nasal application of capsaicin causes sneezing, irritation, and reflex mucus secretion. Its inhalation may cause acute hypertension (similar to ammonia inhalation), which in turn may cause headache and increase the risk of stroke or heart attack.

Eye Exposure

Common ocular symptoms associated with OC spray exposure include redness, swelling, severe burning pain, stinging, inflammation, an involuntary or reflex closing of the eyelids. Ocular exposure to OC should be treated by flushing for at least 15 minutes with fresh water.
