Section III - Physical/Chemical Characteristics of Hazardous Ingredients
Sodium Metasilicate Nonahydrate
BOILING POINT: NA SPECIFIC GRAVITY: NA
VAPOR PRESSURE: N/A SOLUBILITY IN WATER: Soluble APPEARANCE/ODOR: Solid
Section IV - Fire and Explosion Hazard Data
FLASH POINT (Method used): N/A AUTO IGNITION TEMPERATURE: N/A FLAMMABLE LIMITS LEL N/A UEL N/A
N/A
EXTINGUISHING MEDIA: Water, dry chemical or soda ash
SPECIAL FIRE FIGHTING PROCEDURES: Move containers from fire area if you can do so without risk. Apply cooling water to sides of containers that are exposed to
flames until well after fire is out. Stay away from ends of tanks. For massive fire in cargo area, use unmanned hose holder or monitor nozzles, if this is impossible
withdraw from area and let fire burn. Use flooding amounts of water as fog, cool containers with flooding amounts of water, apply from as far a distance as possible.
Avoid breathing corrosive vapors, keep upwind. Consider evacuation of downwind area if material is leaking.
UNUSUAL FIRE AND EXPLOSION HAZARDS: Concentrated nitric acid is not combustible, but is a strong oxidizer and its heat of reaction with reducing agents or
combustibles may cause ignition. Concentrated nitric acid reacts explosively with combustibles organic or readily oxidizable materials such as alcohol, wood, turpentine,
metal powders, etc.
Section V - Reactivity Data
Unstable Stable Conditions to Avoid: Incompatible materials, see above.
STABILITY:
INCOMPATIBILITY (Materials to avoid): Concentrated nitric acid will react with organic and hydrophobic compounds. The analytical standard should not be exposed to
water reactive substances.
HAZARDOUS DECOMPOSITION PRODUCTS: Nitric oxides
HAZARDOUS May Occur Will Not Occur Conditions to Avoid: None known.
POLYMERIZATION:
Section VI - Health Hazard Data
ROUTES OF Inhalation? Yes Skin? Yes Ingestion? Yes
ENTRY
HEALTH (Acute and Chronic): ACUTE: Concentrated nitric acid vapor or mist is an irritant to the eyes and skin. The sample solution may cause irritation if inhaled,
ingested or absorbed through the skin. A burning sensation may occur. With concentrated nitric acid, these symptoms are very severe. CHRONIC: Repeated and
prolonged contact with concentrated nitric acid can result in mouth and bronchial problems. Prolonged skin contact results in dermatitis.
COMPONENTS LISTED AS CARCINOGENS OR POTENTIAL CARCINOGENS: N/A
Page 2
SIGNS AND SYMPTOMS OF EXPOSURE: Irritation of eyes with coughing and burning sensation on skin.
MEDICAL CONDITIONS GENERALLY AGGRAVATED BY EXPOSURE: Individuals with bronchial symptoms and sensitive dermatitis.
EMERGENCY AND FIRST AID PROCEDURES: Seek medical assistance for treatment, observation and support if necessary. EYE CONTACT: Corrosive, may cause
pain, flush with water. Get IMMEDIATE medical attention. SKIN CONTACT: Corrosive, may cause burns, flush with water for several minutes, get medical attention.
INHALATION: Remove to fresh air, if breathing has stopped, start artificial respiration. Obtain medical assistance. INGESTION: Corrosive, immediate pain, dilute the
acid immediately by giving large amounts of water. Do not induce vomiting. If vomiting occurs, administer fluids repeatedly. Ingested acid must be diluted 100 times to
render it harmless to tissue. Obtain medical attention.
Section VII - Precautions for Safe Handling and Use
STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED: May neutralize with lime, limestone, or Sodium Bicarbonate. Absorb with nonreactive
material. Wash down with water.
WASTE DISPOSAL METHOD: Dispose of in a manner consistent with federal, state, and local regulations.
PRECAUTIONS TO BE TAKEN IN HANDLING AND STORAGE: Store at room temperature capped.
OTHER PRECAUTIONS* Avoid vapors, wear protective clothing, gloves.
Section VIII - Control Measures
RESPIRATORY PROTECTION (Please specify): None needed with sample or diluted solution.
VENTILATION: Local exhaust
PROTECTIVE GLOVES: Vinyl or latex EYE PROTECTION: Safety glasses
OTHER PROTECTIVE EQUIPMENT: Impervious Clothing.
EMERGENCY WASH FACILITIES: Maintain eye wash and quick drench showers in work area.
