PHENOLDISULFONIC ACID

EMERGENCY OVERVIEW
Causes severe burns.Corrosive.Water-reactive.
Potential Health Effects
Eye:
Contact with liquid is corrosive to the eyes and causes severe burns. May cause eye injury.
Skin:
Contact with liquid is corrosive and causes severe burns and ulceration.
Ingestion:
May cause severe gastrointestinal tract irritation with nausea, vomiting and possible burns. May cause corrosion and permanent tissue destruction of the esophagus and digestive tract.
Inhalation:
Causes chemical burns to the respiratory tract. Inhalation may be fatal as a result of spasm, inflammation, edema of the larynx and bronchi, chemical pneumonitis and pulmonary edema.
Chronic:
Repeated inhalation may cause chronic bronchitis. Repeated exposure may cause erosion of teeth.

Section 4 - FIRST AID MEASURES
Eyes: Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately.
Skin:
Get medical aid immediately. Immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes.
Ingestion:
Do not induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. Get medical aid immediately.

Section 5 - FIRE FIGHTING MEASURES
General Information:
As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Reacts violently with water.
Extinguishing Media:
Use water spray to cool fire-exposed containers. Use extinguishing media most appropriate for the surrounding fire. If water is the only media available, use in flooding amounts.

Section 6 - ACCIDENTAL RELEASE MEASURES
General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks:
Clean up spills immediately, observing precautions in the Protective Equipment section. Cover with sand, dry lime or soda ash and place in a closed container for disposal. Isolate area and deny entry. Provide ventilation.
