SECTION 3: Hazards Identification
Emergency Overview: Toxic by inhalation, in contact with skin and if swallowed. This material is a strong, corrosive fuming acid. Extremely corrosive to skin, eyes, mucous membranes and respiratory tract.
Primary Routes of Exposure: Ingestion, inhalation, eyes and skin
Eye Contact: Severe corrosive to the eyes. Exposure can lead to permanent eye damage.
Skin Contact: Severe corrosive to skin. Unless treated, contact can lead to delayed deep and painful chemical burns. Toxic in contact with skin.
Inhalation: Material is a fuming liquid releasing toxic and corrosive fumes. Inhalation can lead to burning of the mucous membranes and lungs.
Ingestion: Material is highly toxic and corrosive. Ingestion may be fatal unless immediate treatment is available.
Acute Health Effects: Severe corrosive to eyes, skin, mucous membranes and respiratory tract. Ingestion may be fatal. Hydrofluoric acid, a decomposition byproduct, may cause delayed deep slow healing painful burns.
Chronic Health Effects: Prolonged exposure to hydrolysable fluorine compounds can cause deterioration of bone and tooth structure.
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. After water wash, apply calcium gluconate or water soluble calcium salts as antidote. Seek medical assistance.
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: not applicable
Explosion Limits: not applicable
Extinguishing Medium: None required. Material is non-flammable.
Special Fire Fighting Procedures: If compatible with burning material, water spray will suppress hydrogen fluoride fumes. Fire fighters should use approved self- contained breathing apparatus and full protective clothing.
Hazardous Combustion and Decomposion Products: If involved in a fire this material may emit corrosive fumes of hydrofluoric acid.
Unusual Fire or Explosion Hazards: No unusual fire or explosion hazards.
SECTION 6: Accidental Release Measures
Spill and Leak Procedures: Small spills can be adsorbed into and neutralized with sodium carbonate, sodium bicarbonate or lime powders. In the case of a large spill, the area should be evacuated. Personnel should only enter the area fitted with a self-contained breathing apparatus.
SECTION 7: Handling and Storage
Handling and Storage: Store in a tightly sealed non-metallic container. Keep away from heat and direct sunlight. Material can fume strongly on exposure to air. Handle the material only in an efficient fume hood.
SECTION 8: Exposure Controls and Personal Protection
Eye Protection: In addition to approved safety glasses, a face shield should be worn when working with this material.
Skin Protection: When handling this material rubber gloves and an apron should be worn.
Ventilation: Material has a pungent odor. Always handle material in an efficient fume hood.
Respirator: In the absence of adequate ventilation a respirator should be worn. The use of a respiratory requires a Respirator Protection Program to be in compliance with 29 CFR 1910.134.
Additional Protection: No additional protection required.
