Deputy School Exam 5 Practice

In riot-control chemistry, how strong an agent is depends on how intensely it irritates the eyes and airways and how long its effects last. CS tear gas is stronger because it produces more intense irritation and tends to linger on surfaces and in the environment, delivering a longer, more persistent irritant effect. CN, while irritating, volatilizes more readily and dissipates faster, leading to a quicker but shorter-lived response and generally less overall irritant strength. So, CS is considered the stronger agent.
