PERSONAL PROTECTION INFORMATION
Respiratory Protection: A NIOSH approved respirator should be worn.
Self-contained breathing apparatus may be required when chemical is heated to decomposition
or in a spill area.
Eye and Face Protection: Splash-proof goggles should be worn when there is danger
of splash from solution containing chemical. Protection against splash or mist from solution
containing chemical with 8-inch minimum face shield is recommended. Eye protection should be
worn in presence of dry chemical, or solution containing chemical, at all times.
Hand, Arm and Body Protection: Impervious gloves should be worn. Protective, impervious clothing
should be worn in presence to prevent contact with skin (coveralls, boots, etc.)
Other Protective Clothing and Equipment: Protect open wounds. Heating to decomposition
requires full protective clothing and self-contained breathing apparatus.
Engineering Controls: Adequate ventilation to maintain fluoride concentrations below
applicable standards.

Primary Route(s) of Entry: Eye and skin contact, inhalation
Symptoms of Exposure: Prickling or burning sensation of skin and mucous membranes.
Coughing, sneezing,tightness of chest, difficulty in breathing.
Acute: Inhalation of dust or mist may cause severe mucous membrane irritation and
burns. Effects may not be immediately apparent, especially with diluted solutions. First aid
procedures should be followed even in cases of suspected contact.
Chronic: Causes severe skin irritation and burns. Ingestion or inhalation may be
harmful and possibly fatal depending on severity and length of over-exposure. Chronic over-
exposure may cause fluorosis. Product may be absorbed through the skin and produce signs
of fluorosis such as weight loss, brittleness of bones, anemia, weakness and stiffness of
joints. Internal bleeding may develop. First aid procedures should be followed even in cases
of suspected contact.
Aggravated Medical Condition: Any skin disorder, respiratory and/or mucous membrane
condition.
Toxic Data: LD
50 200 mg/kg (Oral - Rat)
Section IV
EMERGENCY AND FIRST AID PROCEDURES
Inhalation: Remove exposed person promptly to fresh air. If breathing has
stopped, perform artificial respiration. Oxygen should be provided for a person having
difficulty breathing (but only administered by an authorized individual) until the person
is able to breathe easily by themselves. Keep the affected person warm and at rest. Get
medical attention as soon as possible.
Eye Contact: If chemical or solution containing chemical contacts the eyes,
immediately flush eyes with large amounts of water, lifting the upper and lower lids
at periodic intervals to insure contact of water with all accessible tissue of the eyes
and lids. Medical attention should be given as soon as possible, preferably an eye specialist.
Skin Contact: If chemical, or solution containing chemical, gets on the skin, promptly
wash the contaminated skin using soap or mild detergent and water. If chemical, or solution
containing chemical soaks through clothing, remove the clothing promptly and wash the skin
using soap or mild detergent and water. If irritation persists after washing, get medical attention as soon
as possible.
Ingestion: Do
NOT induce vomiting. If conscious, give the exposed person
large quantities of water immediately to dilute the acid. Several glasses of milk may be given
for its soothing effect. A physician should be contacted immediately.
Note to Physician: Exposed person should be observed for 48 - 72 hours for delayed
onset of pulmonary edema.

REACTIVITY
Stability: Stable.
Hazardous Polymerization: Will not occur.
Conditions and Materials to Avoid: Strong acids, water, heat in excess
of 100°C. These situations may cause formation of toxic irritating hydrogen fluoride gas.
Hazardous Decomposition Products: Temperatures above 100°C, such as fires,
will cause decomposition and release highly toxic hydrogen fluoride gas to form and/or
hydrofluoric acid, which is very corrosive.
Section VIII
FIRE AND EXPLOSION HAZARDS
Flash Point and Method Used: N/A
Flammable Limits - % Volume in Air: Lower N/A
Upper N/A
Extinguishing Media: This chemical is not flammable, but for fires in area where
this chemical is stored, foam, dry chemicals or CO
2 may be used.
Special Fire Fighting Procedures and Precautions: Although this chemical is not
flammable, when heated to temperatures exceeding 100°C, it will emit very toxic fumes of
fluorine and nitrogen oxides. Firefighters should avoid all bodily contact, wear full protective
clothing and NIOSH approved self-contained breathing apparatus.
Auto Ignition Temperature: N/A
Unusual Fire and Explosion Hazards: When this product is heated to temperatures
exceeding 100°C, it will emit very toxic fumes of fluorines. Firefighters should avoid
all bodily contact, wear full protective clothing and self-contained breathing apparatus.
Section IX
STORAGE AND SPECIAL PRECAUTIONS
Handling and Storing Precautions: Store in a cool, dry place and away from acids. Use
only with adequate ventilation, dust mask or self-contained breathing apparatus. Protective
clothing should always be worn. Avoid contact with eyes, skin, and clothing. Keep bag or
container closed when not in use. Avoid breathing dust or mist.
Ventilation: Provide adequate general and/or local exhaust to maintain vapors below
acceptable air level maximums.
Other Precautions: If chemical should become heated in excess of 100°C, it will
decompose, releasing highly toxic hydrogen fluoride gas. If contact with water occurs,
hydrofluoric acid will form, which is highly corrosive.
