Effects of Overexposure: INHALATION:Fumes may be corrosive & toxic.Symptoms of exposure include headache, nausea, dizziness, coughing, and painful redness of eyes.
INGESTION: May be corrosive and toxic. May cause, burns of mouth, throat, esophagus, and gastrointestinal tract. May cause nausea, dizziness, and headache.
SKIN CONTACT:Corrosive and irritant. Can cause redness,pain and burns. May cause tissue scarring and damage.
EYE CONTACT: Corrosive and irritant. Vapors and liquid may cause irritation to the eyes with redness, tearing, and pain. Repeated or chronic contact may cause irreversible tissue damage.
Chronic Effect: Frequent or prolonged exposure has a destructive effect on tissue. May result in skin disorders, pulmonary irritation, and visual impairment.
Emergency and First Aid Procedures:
INHALATION: Remove person to fresh air. If breathing stops, perform cardio-pulmonary resuscitation. Have oxygen ready for administration by a trained person if breathing is difficult. Immediately obtain medical assistance.
INGESTION: Never give anything by mouth to an unconscious person. If conscious, give several glasses of water or milk. Do not induce vomiting, but spontaneous vomiting may occur. Immediately obtain medical care and contact local poison control center for most current antidote.
SKIN CONTACT: Flood area with water for at least 15 minutes. Remove contaminated clothing and shoes. Wash clothing and clean shoes thoroughly before reuse. Obtain medical care.
EYE CONTACT: Immediately flush eyes with plenty of water for 15 minutes while holding lids gently, but firmly, apart. Lift upper and lower lids occasionally to ensure thorough flushing under them. Seek immediate medical aid.
Medical Conditions Aggravated by Exposure: Individuals who have pre-existing eye problems, skin disorders, or impaired liver, kidney, or respiratory function may experience increased susceptibility to substance effects.
