Tear gas exposure prompts a flight status decision because it can irritate the eyes and airways and, in some individuals, trigger delayed respiratory or ocular symptoms. The safety-first approach is to give the aircrew time to recover and to watch for any late-developing impairment that could affect flight performance, judgment, or safety.

A 48-hour grounding period is used because symptoms such as eye irritation, tearing, photophobia, coughing, or chest tightness can persist or recur after the initial exposure, especially with physical exertion or continued exposure in a stressful environment. Even in the absence of systemic symptoms at first, there’s a real risk of delayed bronchospasm or impaired vision and comfort that could compromise flying safety. Waiting 48 hours allows a clear assessment window to ensure the individual is fully capable of operating aircraft safely.

shorter intervals (like 12 or 24 hours) risk missing late symptoms, while grounding only for systemic symptoms would not account for lingering local irritation that can still impair performance. The 48-hour rule provides a conservative, safety-centered standard for determining when flight duties can resume.
