Treatment of Riot Control Agents: Tear Gas and Pepper Spray

by Orwell Warned
History, description, effects, and treatment of riot control agents (Tear Gas and Pepper Spray). Treatment recommendations taken from the U.S. Army's Chemical Casualty Care Division. Full document available at:

MEDICAL CARE

The effects from riot control agents are usually self-limiting, and medical attention is usually not required. Exiting the contaminated area should bring some measure of relief in 15 to 30 minutes or sooner. In rare circumstances, complications may occur on the skin, in the eyes, or in the airways.

Decontamination

The use of water on the skin may result in transient worsening of the burning sensation. Soap and water may be more effective but may also cause a momentary increase in the symptoms. CS rapidly hydrolyzes in an alkaline solution; a solution containing 6% sodium bicarbonate, 3% sodium carbonate, and 1% benzalkonium chloride was found to bring prompt relief of symptoms and to hydrolyze the agent. No form of hypochlorite should be used.

Skin

For dermatitis, a topical steroid preparation (eg, triamcinolone acetonide, fluocinolone acetonide, flurandrenolone, or betamethasone-17-valerate) is the principal therapeutic agent. Oozing lesions should be treated with wet dressings (moistened with fluids such as 1:40 Burow’s solution). Appropriate antibiotics should be given for secondary infection, and oral antihistamines for itching. Vesicating lesions have been successfully treated with compresses of a cold silver nitrate solution (1:1,000) for 1 hour, applied six times daily. One person with severe lesions and marked discomfort was given a short course of an oral steroid. An antibiotic ointment was applied locally, but systemic antibiotics were not used.

Eye

A local anesthetic might be applied once for severe pain, but continued use should be restricted. The eye should be thoroughly flushed to remove any particles of the agent. If the lesion is severe, the patient should be sent to an ophthalmologist.

Respiratory Tract

Usually, the cough, chest discomfort, and mild dyspnea are gone 30 minutes after exposure to clean air. However, both the animal data (detailed in the section on CS) and the clinical experience with the infant exposed to CS suggest that severe respiratory effects may not become manifest until 12 to 24 hours after exposure. An individual who has prolonged dyspnea or objective signs should be hospitalized under careful observation. Further care should be as described in Chapter 9 (http://ccc.apgea.army.mil/Documents/HTML_Restricted/chapters/Chapter_9.htm), Toxic Inhalational Injury. Although people with chronic bronchitis have been exposed to riot control agents without untoward effects, any underlying lung disease (eg, asthma, which affects one person in six in the general, or the military, population) might be exacerbated by exposure to CS.

Cardiovascular System

Transient hypertension has been noted after exposure to riot control agents, primarily because of the anxiety or pain of exposure rather than a pharmacological effect of the compound. Whatever the cause, adverse effects may be seen in individuals with hypertension, cardiovascular disease, or an aneurysm.

by tears in my eyes
There are a number of easily available treatments for tear gas and pepper spray. Don't believe the hype posted here, just because it is from 'official' sources. How many of you carry around local anesthetic in your pocket or 1st aid kit?
Refer to the Quebec Street Medic information site or Black Cross Health Collective or any reliable 1st Aid worker at a demo for accurate information on the use of Maalox and water, Mineral Oil and rubbing alcohol or just plain vinegar-soaked handkerchiefs and fresh air for tear gas.
In the meantime, get back on the street.
We are 100% volunteer and depend on your participation to sustain our efforts!
