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
Engineering Controls: Adequate ventilation to maintain fluoride
concentrations below applicable standards.

OSHA Health Hazard Classification: N/A
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
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: LD50 150
mg/kg (Oral - Rat)
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. Medical attention should be given as soon as possible for all burns,
regardless of how minor they seem.
Ingestion: Do NOT induce vomiting. If conscious, give the
exposed person large quantities of water immediately. 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.

Hazardous Polymerization: Will not occur.
Conditions and Materials to Avoid: Strong acids, water, heat in
excess of 100°C. These situations will cause highly toxic hydrogen fluoride
gas to form and/or hydrofluoric acid, which is very corrosive.
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.
FIRE AND EXPLOSION HAZARDS
Flash Point and Method Used: N/A
Flammable Limits - % Volume in Air: Lower N/A
Extinguishing Media: This chemical is not flammable, but for fires
in area where this chemical is stored, foam, dry chemicals or CO2
may be used.
Unusual Fire and Explosion Hazards: When this product is 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 self-contained breathing apparatus.
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
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.
Waste Disposal Method: Used
or unused product should be tested to determine hazard status and disposer must
comply with federal, state, and local disposal or discharge laws.
