[Occupational asthma in a teacher after repeated exposure to tear gas]

Acute exposure to tear gas causes generally reversible cutaneous and mucosal irritations. Lasting respiratory manifestations after exposure are exceptional. We report the case of a 26-year-old female teacher with no history of respiratory disease who developed asthma after repeated exposure to tear gas discharged in her class room. The disorders occurring during these repeated exposures to the irritating gas were consistent with the recently described low level reactive airway dysfunction syndrome (low level RADS).
