Potential Health Effects
If inhaled or swallowed, this compound can cause fluoride poisoning. Early symptoms include nausea,
vomiting, diarrhea, and weakness. Later effects include central nervous system effects, cardiovascular effects
and death.

MSDSNumber: A5810 ffective Date: 11/21/00Supercedes: 11/17/99
Inhalation:
May cause irritation and burns to the respiratory tract, symptoms may include coughing, sore throat, and
labored breathing. May be absorbed through inhalation of dust; symptoms may parallel those from ingestion
exposure. Irritation and burning effects may not appear immediately.
Ingestion:
May cause salivation, nausea, vomiting, diarrhea, and abdominal pain, followed by weakness, tremors,
shallow respiration, cardopedal spasm, convulsions, and coma. May cause brain and kidney damage. Death
may be caused by respiratory paralysis. Affects heart and circulatory system.
Skin Contact:
Solution is acidic and can cause severe burns, especially in sensitive areas of the skin. Effects may not appear
immediately. May be absorbed through the skin with possible systemic effects.
Eye Contact:
May cause irritation and serious eye damage.
Chronic Exposure:
Chronic exposure may cause mottling of teeth and bone damage (osteosclerosis) and fluorosis. Symptoms of
fluorisis include brittle bones,weight loss, anemia, calcified ligaments, general ill health and joint stiffness.
Aggravation of Pre-existing Conditions:
Populations that appear to be at increased risk from the effects of fluoride are individuals that suffer from
diabetes insipidus or some forms of renal impairment.
4. First Aid Measures
First aid procedures should be pre-planned for fluoride compound emergencies.
Inhalation:
If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.
CALL A PHYSICIAN IMMEDIATELY.
Ingestion:
Administer milk, chewable calcium carbonate tablets or milk of magnesia. Never give anything by mouth to an
unconscious person. CALL A PHYSICIAN IMMEDIATELY.
Skin Contact:
Wipe off any excess material from skin and then immediately flush skin with large amounts of soapy water.
Remove contaminated clothing and shoes. Wash clothing before re-use. Apply bandages soaked in
magnesium sulfate. CALL A PHYSICIAN IMMEDIATELY.
Eye Contact:
Immediately flush eyes with gentle but large stream of water for at least 15 minutes, lifting lower and upper
eyelids occasionally. Call a physician immediately.
Note to Physician:
For large exposures, systemic effects (hypocalcemia and hypomagnesia) may occur.
5. Fire Fighting Measures
Fire:
Not considered to be a fire hazard. If involved in a fire, can emit toxic fumes and irritating and corrosive gases.
Explosion:
May react with metals to form flammable hydrogen gas.
Fire Extinguishing Media:
Use any means suitable for extinguishing surrounding fire. Water spray may be used to extinguish surrounding
fire and cool exposed containers. Water spray will also reduce fume and irritant gases.
Special Information:
In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus
with full facepiece operated in the pressure demand or other positive pressure mode.
6. Accidental Release Measures
Page 2 of 6
MSDS Number: A5810 ffective Date: 11/21/00 Supercedes: 11/17/99
Ventilate area of leak or spill. Wear appropriate personal protective equipment as specified in Section 8.
Isolate hazard area. Keep unnecessary and unprotected personnel from entering. Contain and recover liquid
when possible. Neutralize with alkaline material (soda ash, lime), then absorb with an inert material (e. g.,
vermiculite, dry sand, earth), and place in a chemical waste container. Do not use combustible materials, such
as saw dust. Do not flush to sewer! US Regulations (CERCLA) require reporting spills and releases to soil,
water and air in excess of reportable quantities. The toll free number for the US Coast Guard National
Response Center is (800) 424-8802.
7. Handling and Storage
Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against physical damage.
Isolate from acids and alkalis. Solution is acid. Can cause glass and metal corrosion. Containers of this
material may be hazardous when empty since they retain product residues (vapors, liquid); observe all
warnings and precautions listed for the product.
8. Exposure Controls/Personal Protection
Airborne Exposure Limits:
-OSHA Permissible Exposure Limit (PEL):
2.5 mg (F)/m3 (TWA)
-ACGIH Threshold Limit Value (TLV):
2.5 mg (F)/m3 (TWA) 5 mg (F)/m3 (STEL)
-OSHA Permissible Exposure Limit (PEL):
3 ppm (TWA) , 6 ppm (STEL) for Hydrogen Fluoride
-ACGIH Threshold Limit Value (TLV):
3 ppm Ceiling as F for hydrogen fluoride
Ventilation System:
A system of local and/or general exhaust is recommended to keep employee exposures below the Airborne
Exposure Limits. Local exhaust ventilation is generally preferred because it can control the emissions of the
contaminant at its source, preventing dispersion of it into the general work area. Please refer to the ACGIH
document, "Industrial Ventilation, A Manual of Recommended Practices", most recent edition, for details.
Personal Respirator (NIOSH Approved)
If the exposure limit is exceeded, a full facepiece respirator with an acid gas cartridge and dusUmist filter may
be worn up to 50 times the exposure limit, or the maximum use concentration specified by the appropriate
regulatory agency or respirator supplier, whichever is lowest. For emergencies or instances where the
exposure levels are not known, use a full-facepiece positive-pressure, air-supplied respirator. WARNING: Air
purifying respirators do not protect workers in oxygen-deficient atmospheres.
Skin Protection:
Wear impervious protective clothing, including boots, gloves, lab coat, apron or coveralls, as appropriate, to
prevent skin contact.
Eye Protection:
Use chemical safety goggles and/or a full face shield where splashing is possible. Maintain eye wash fountain
and quick-drench facilities in work area.
