SECTION 2: Composition and Information on Ingredients
Ingredient CAS Number Percent ACGIH (TWA) OSHA (PEL)
Title Compound 10049-10-2 100 0.5mg/m3 (as Cr) 0.5mg/m3 (as Cr)
SECTION 3: Hazards Identification
Emergency Overview: If inhaled or swallowed this compound may cause fluoride poisoning by reducing cellular calcium function. Early symptoms include nausea, vomiting, diarrhea, and weakness. Corrosive to skin and eyes.
Primary Routes of Exposure: Ingestion, inhalation, skin, eyes
Eye Contact: Causes serious eye damage. Effects may not immediately appear.
Skin Contact: Causes burning with redness and pain. Soluble fluoride may be corrosive. Effects may not appear immediately
Inhalation: Inhalation of dust causes severe irritation to the respiratory tract, causing coughing, sore throat, and labored breathing.
Ingestion: May cause salivation, nausea, vomiting, diarrhea, and abdominal pain.
Acute Health Effects: Fluoride poisoning may cause nausea, vomiting, diarrhea, weakness, coma, and respiratory paralysis. Corrosive to skin and eyes.
Chronic Health Effects: Prolonged exposure to soluble fluorine compounds can cause deterioration of bone and tooth structure, and kidney damage. Although less toxic than Chromium (VI), some animal studies show chromium (III) to act as a mutagen and tumorigen.
NTP: yes
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 required
Special Fire Fighting Procedures: If 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: none
Unusual Fire or Explosion Hazards: No unusual fire or explosion hazards.
SECTION 6: Accidental Release Measures
Spill and Leak Procedures: To avoid raising dust, small spills may be mixed with diatomaceous earth, sand, vermiculite or other suitable inert material and swept up.
SECTION 7: Handling and Storage
Handling and Storage: Store solid in a tightly sealed container.
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 glove manufacturer to determine the proper type of glove.
Ventilation: If possible, handle the material 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.
