IV FIRE AND EXPLOSION HAZARDS DATA
Flash Point: N/A Autoignition Temperature: N/E
Flammable Limits: Lower: N/E Upper: N/E
Extinguishing Media: CO2, dry chemical, water spray or regular foam.
Special Firefighting Procedures: Firefighters must wear full face, self-contained breathing apparatus with full protective clothing to
prevent contact with skin and eyes. Fumes form fire are hazardous. Isolate runoff to prevent environmental pollution.
Unusual Fire & Explosion Hazards: When burned, hazardous products of combustion including fumes of carbon monoxide, carbon
dioxide, and fluorine can occur. Avoid breathing fumes from fire exposed material. Avoid needless exposure to gas, fume or vapor.
If practical, remain upwind when approaching a fire outdoors, even when wearing a corrosive and/or toxic gases. Some of these
materials may burn, but none ignite readily. Containers may explode when heated.
V HEALTH HAZARD INFORMATION
Effects of Exposure:
Long-term overexposure to fluorides results from excessive deposition in bone which is the primary target organ. Dental
fluorosis typically results in staining and pitting of teeth in humans with fluoride concentrations in the drinking water greater than 2
ppm. At higher fluoride levels in the drinking water (greater than 10 ppm), skeletal fluorosis and osteosclerosis have been observed.
Epidemiology studies of human populations exposed to fluoride in the drinking water have not shown any evidence for an increase in
cancer or birth defects. Fluoride is readily absorbed in the lungs from inhalation and in the gastrointestinal tract. Both uptake in bone
and urinary excretion are rapid processes. Daily retention in bone of increased amounts of fluoride intake is estimated to be 50%. If
intake is reduced, a two-phase resorption of fluoride from bone occurs with a rapid process on the order of weeks and a slower phase
with a half-life of 8 years.
Acute and Chronic Effects:
Inhalation and skin contact are expected to be the primary routes of occupational exposure to sodium fluoride. Based on
single exposure animal tests, sodium fluoride is considered to be moderately toxic if swallowed, no more than slightly toxic if
absorbed through the skin, slightly irritating to skin and corrosive to eyes. Severe or repeated exposure may cause kidney damage and
bone effects including joint pain, tooth erosion and discoloration. Workers with kidney disease should limit exposure to this material.
Target Organs: Eyes, skin, kidney, liver, lung, bone.
EMERGENCY AND FIRST AID PROCEDURES:
INHALATION: Remove to fresh air.
INGESTION: Induce vomiting immediately by medical personnel. Get medical attention. Call a Poison Control Center. Never give
anything by mouth to an unconscious person.
SKIN: Flush the area with plenty of water. Remove contaminated clothing and shoes. Wash clothing before reuse. Get medical
attention. Thoroughly clean shoes before reuse.
EYE: Immediately flush with plenty of water for at least 15 minutes. Get medical attention immediately.
VI REACTIVITY DATA
Stability: Stable
Conditions to Avoid: N/A
Incompatibility (Material to avoid): Contact with acids or water may result in a low energy release.
Hazardous Decomposition Products: None known
Hazardous Polymerization: Will not occur.
VII SPILL OR LEAK PROCEDURES
Steps to Be Taken in Case Material Is Released or Spilled: Stop the leak if you can do so without risk. Ventilate the space
involved. Fully encapsulating, vapor protective clothing should be worn for spills and leaks with no fire. Do not touch or walk
through spilled material. Prevent entry into waterways, sewers, basements, or confined areas. Avoid generation of dusts. Remove
from spill location. Decontaminate area.
Waste Disposal Method: Dispose of in accordance with Federal, State and Local regulations.
VIII SPECIAL PROTECTION INFORMATION
Respiratory Protection: NIOSH approved dust-fume-mist cartridge respirator.
Ventilation: Use local exhaust to maintain concentration of exposure below PEL, TLV. Use adequate ventilation.
Protective Gloves: Polyvinyl chloride, natural rubber, polyethylene.
Eye Protection: Chemical goggles.
Other Protective Clothing or Equipment: Protective gear suitable to prevent contamination.
IX SPECIAL PRECAUTIONS
Precautions to Be Taken in Handling and Storage: Do not get in eyes, on skin or on clothing. Avoid breathing dust. Do not taste
or swallow. Use only with adequate ventilation. Keep container closed. Wash thoroughly after handling. This material is not
hazardous under normal storage conditions, however, material should be stored in closed containers, in a secure area to prevent
container damage and subsequent spillage.
Work Practices: Implement engineering and work practice controls to reduce and maintain concentration of exposure. Use good
housekeeping and sanitation practices. Do not use tobacco or food in work area. Wash thoroughly before eating or smoking. Do not
blow dust off clothing or skin with compressed air. Maintain eyewash capable of sustained flushing, safety drench shower and
facilities for washing.
The above information is believed to be correct, but does not purport to be all inclusive and shall be used only as a guide.
ESPI shall not be held liable for any damage resulting from handling or from contact with the above product.
