SECTION 3: Hazards Identification
Emergency Overview: Corrosive to skin and eyes. Material hydrolyzes in contact with moisture releasing toxic and corrosive fumes of hydrogen chloride and aqueous hydrochloric acid.
Primary Routes of Exposure: Contact with skin and eyes. Inhalation of dust.
Eye Contact: Corrosive irritant to the eyes.
Skin Contact: Corrosive to skin.
Inhalation: Forms hydrogen chloride in the presence of moisture. Inhalation can lead to burning of the respiratory tract.
Ingestion: No information is available on the acute physiological effects of ingestion.
Acute Health Effects: Corrosive to skin, eyes and respiratory tract. Causes eye and skin burns, dyspnea (difficulty breathing) and pulmonary edema.
Chronic Health Effects: No information available on long-term chronic effects.
NTP: No
IARC: No
OSHA: No
SECTION 4: First Aid Measures
Eye Exposure: Immediately flush the eyes with copious amounts of water for at least 10-15 minutes. A victim may need assistance in keeping their eye lids open. Get immediate medical attention.
Skin Exposure: Wash the affected area with water. Remove contaminated clothes if necessary. Seek medical assistance if irritation persists.
Inhalation: Remove the victim to fresh air. Closely monitor the victim for signs of respiratory problems, such as difficulty in breathing, coughing, wheezing, or pain. In such cases seek immediate medical assistance.
Ingestion: Seek medical attention immediately. Keep the victim calm. Give the victim water (only if conscious). Induce vomiting only if directed by medical personnel.
SECTION 5: Fire Fighting Measures
Flash Point: not applicable
Autoignition Temperature: none
Explosion Limits: none
Extinguishing Medium: None. Material is non-flammable.
Special Fire Fighting Procedures: If this product is involved in a fire, fire fighters should be equipped with a NIOSH approved positive pressure self-contained breathing apparatus and full protective clothing.
Hazardous Combustion and Decomposion Products: If involved in a fire this material may emit toxic fumes of hydrogen chloride.
Unusual Fire or Explosion Hazards: No unusual fire or explosion hazards.
SECTION 6: Accidental Release Measures
Spill and Leak Procedures: Small spills can be mixed with powdered sodium bicarbonate, lime, or calcium carbonate and swept up. Avoid raising dust.
SECTION 7: Handling and Storage
Handling and Storage: Store solid in a tightly sealed bottle away from moisture. If possible, handle solid in an efficient fume hood. Prolonged exposure to the atmosphere will lead to degradation of the product.
SECTION 8: Exposure Controls and Personal Protection
Eye Protection: Always wear approved safety glasses when handling a chemical substance in the laboratory.
Skin Protection: Wear protective clothing and gloves. Consult with glove manufacturer to determine the proper type of glove.
Ventilation: The solid may form corrosive vapors. It should be handled in an efficient fume hood.
Respirator: If in form of fine dust and ventilation is not available a respirator should be worn. The use of respirators requires a Respirator Protection Program to be in compliance with 29 CFR 1910.134.
Additional Protection: No additional protection required.
