Special Firefighting Procedures:
As appropriate for surrounding fire.
Unusual Fire And Explosion Hazards:
Hot or molten materials will react violently with water, liberating heat and causing splashing. Contact with metals,
particularly magnesium, aluminum, and zinc (galvanized), can rapidly generate hydrogen gas which is explosive.

Section 5 - Reactivity Data
Stability: Conditions To Avoid:
Stable Can react violently with acids and with many organic compounds.
Incompatability Aluminum, tin, lead, zinc, and their alloys and all acids.
(Materials To Avoid):
Hazardous Decomposition: Reaction with various food sugars may form carbon monoxide.
Hazardous Polymerization: Caustic soda & trichloroethylene are especially hazardous since they react to form
dichloracetylene which is spontaneously flammable.
Section 6 - Health Hazard Data
Routes of Entry: Inhalation Skin Ingestion
YES/Primary YES/Primary YES/Secondary
Health Hazards:
Caustic Soda is a corrosive material. Sodium Hydroxide: Acute Oral LD50=140-340 mg/kg (Rat) Acute Dermal
LD50=1.35 gm/kg (Rabbit)
Carcinogenicity: NTP IARC OSHA Regulated
NO NO NO
Signs And Symptoms of Exposure:
INHALATION: Airborne concentrations of dust, mist, or spray of caustic soda may cause damage to the upper
respiratory tract and even to the lung tissue proper which could produce chemical pneumonia, depending upon the
severity of exposure. SKIN CONTACT: Caustic soda is destructive to tissues contacted and produces severe
burns. EYE CONTACT: Caustic Soda is destructive to eye tissues on contact. Will cause severe burns that result in
damage to the eyes and even blindness. INGESTION: Caustic soda, if swallowed, can cause severe burns and
complete tissue perforation of mucous membranes of the mouth, throat, esophagus, and stomach.
Medical Conditions Generally Aggravated By Exposure:
EFFECTS OF OVEREXPOSURE -- ACUTE OVEREXPOSURE: Corrosive to all body tissues with which it comes in
contact. CHRONIC OVEREXPOSURE: Chronic local effect may consist of multiple areas of superficial destruction
of the skin or of primary irritant dermatitis. Similarly, inhalation of dust, spray or mist may result in varying degrees of
irritation or damage to the respiratory tract tissues and an increased susceptibility to respiratory illness.
Emergency And First Aid Procedures:
EYES: Object is to flush material out immediately then seek medical attention. Immediately flush eyes with large
amounts of water for at least 15 minutes, holding lids apart to ensure flushing of the entire surface. Washing eyes
within 1 minute is essential to achieve maximum effectiveness. Seek medical attention. SKIN: Wash contaminated
areas with plenty of water. Remove contaminated clothing and footwear and wash clothing before reuse. Discard
footwear which cannot be decontaminated. Seek medical attention immediately. INHALATION: Get person out of
contaminated area to fresh air. If breathing has stopped, resuscitate and administer oxygen if readily available.
Seek medical attention immediately. INGESTION: Never give anything by mouth to an unconscious person. If
swallowed, do not induce vomiting. Give large quantities of water. If available give several glasses of milk. If
vomiting occurs spontaneously, keep airways clear. Seek medical attention immediately.

Section 7 - Precautions For Safe Handling And Use:
Steps To Be Taken In Case Material Is Released Or Spilled:
Get complete protective equipment. Shovel spilled material into steel containers, flush with ample water, rinse with
dilute acid, preferably acetic acid, and finally with water.
Waste Disposal Method:
Dissolve and/or flush to holding area for pH adjustment and dilute before discharging to sewer or stream. For large
quantities follow state/local regulations.
Precautions To Be Taken In Handling And Storing:
Store in a cool, dry place. Keep separate from acids, metal, explosives, organic peroxides and easily ignitable
materials.
Other Precautions:
Wear complete protective equipment in handling the product in large quantities.
Section 8 - Control Measures:
Respiratory Protection:
Filter or dust-type respirator.
Special N/A
Ventilation: Local Exhaust As required to control dust or mist.
Mechanical N/A N/A
Other:
Neoprene rubber or vinyl.
Gloves:
Eye Protection: Chemical safety goggles plus face shield where appropriate.
Other Protective
Rubber safety toe shoes or boots, cotton overalls.
Clothing:
Work/Hygienic Practices Use good personal hygiene practices.
