What does the wait time after tear gas indicate about grounding requirements?

• A. No grounding unless systemic residual side effects
• B. Always ground for 24 hours
• C. Ground only if dizziness occurs
• D. Ground for 12 hours

Answer: (A)

Tear gas is mainly a local irritant with little chance of ongoing systemic toxicity. The reason for a waiting period after exposure is to ensure there are no systemic effects that could impair performance. If there are no systemic symptoms—no dizziness, chest tightness, shortness of breath, headache, or generalized malaise—the crew member does not need to be grounded. Grounding is needed only when systemic residual side effects persist after exposure. Once those systemic symptoms have resolved, flight duties can be resumed.
