esophagus, and stomach; mucous membranes turn white; vomiting, severe purging, weak pulse,
cardiovascular collapse, neuromuscular symptoms. Contact with eyes causes irritation. Contact with
skin causes irritation of severe burns; General Treatment for Exposure: Speed is essential.
INHALATION: remove to fresh air. INGESTION: call physician immediately; induce vomiting.
EYES: flush with water and seek medical attention. SKIN: flush with water. OTHER: watch for
swelling of the glottis and delayed constriction of the esophagus; Toxicity by Inhalation (Thresho1dLim.t
