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.
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:
Causes severe irritation and possibly burns to the skin. May be absorbed through
the skin. Effects may not appear immediately.
Eye Contact:
Causes irritation. May be extremely irritating with possible burns to eye tissue
and permanent eye damage may result.
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.
Explosion:
Not considered to be an explosion hazard. Reacts with chlorine trifluoride to
form explosive reaction product.
Fire Extinguishing Media:
Dry chemical, foam or carbon dioxide. 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
Ventilate area of leak or spill.
Wear appropriate personal protective equipment as specified in Section 8. Spills:
Pick up and place in a suitable container for reclamation or disposal, using
a method that does not generate dust. 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.
Store in a cool, dry, ventilated area. Protect against physical damage. Separate
from acids and alkalis. Containers of this material may be hazardous when empty
since they retain product residues (dust, solids); 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)
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 Respirators (NIOSH Approved):
If the exposure limit is exceeded, a half-face dust/mist respirator may be worn for up to ten times the exposure limit or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier, whichever is lowest. A full-face piece dust/mist respirator 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 full face shield where dusting or splashing
of solutions is possible. Maintain eye wash fountain and quick-drench facilities
in work area.
