Riot control agents like CS and OC are generally safe but can cause harm with high or prolonged exposure. More research is needed to understand their long-term health effects and risks.
Area of Science:
- Toxicology
- Pharmacology
- Public Health
Background:
- Riot control agents (RCAs) aim to temporarily disable individuals via mucous membrane and skin irritation.
- Older agents like CN and DM have been replaced by newer agents such as CS and OC.
- Despite being considered safer, widespread RCA use raises health and safety concerns.
Purpose of the Study:
- To review the health effects and safety of riot control agents.
- To highlight the risks associated with high exposure levels and prolonged use.
- To identify the need for further research on the chronic effects of RCAs.
Main Methods:
- Literature review of existing studies on riot control agents.
- Analysis of toxicity data for agents including CS, CR, and OC.
- Examination of reported adverse events and fatalities.
Main Results:
- Modern RCAs (CS, CR) have a wide safety margin but are not risk-free.
- High exposure levels and prolonged durations increase the risk of ocular, pulmonary, and dermal injury.
- Deaths are rare but have occurred with prolonged, high-concentration exposures, including with OC.
Conclusions:
- While modern RCAs have low toxicity, risks exist, particularly in enclosed spaces or with extended use.
- Long-term/chronic effects of RCAs are not well understood.
- Further research is crucial to define the biological actions and full health consequences of RCAs.
