Effects of Overexposure:INFLAMMATION OF THE NOSE, THROAT, UPPER
RESPIRATORY TRACT, IRRITATION, COUGH, CHEST PAIN, NAUSEA, VOMITING,
COLLAPSE. VERY CORROSIVE CAUSES SEVERE BURNS AND DAMAGE TO ALL
TISSUES.
Medical Cond Aggravated by Exposure:PERSONS WITH A HISTORY OF AILMENTS
OR WITH A PRE-EXISTING DISEASE INVOLVING THE EYES, SKIN, OR
