Section II
PERSONAL PROTECTION INFORMATION
Respiratory Protection: A NIOSH approved single-use dust respirator.
Self-contained breathing apparatus may be required when dealing with spills or when
heated to decomposition.
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.

HEALTH INFORMATION
OSHA Permissible Exposure Limit (PEL): 2.5mg/m
3(as F)
ACGIH Threshold Limit Value (TLV): 2.5mg/m
3(as F)
Listing in the following:
Massachusetts "Right to Know" laws - Yes
New Jersey "Right to Know" laws - Yes
Toxic Substances Control Act Inventory of toxic Substances (TSCA) - Yes
Comprehensive Env. Response, Compensation & Liability Act (CERCLE) - Yes
Workplace Hazardous Materials Information System (WHMIS) - Yes
OSHA Health Hazard Classification: Toxic.
Primary Route(s) of Entry: Inhalation, eye and skin contact, ingestion.
Symptoms of Exposure:
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.
Aggravated Medical Condition: Any skin, respiratory or mucous membrane conditions.
toxic Data: 180 mg/kg (Oral - Rat)
Section IV
EMERGENCY AND FIRST AID PROCEDURES
Inhalation: If a person breathes in chemical dust or mist, remove exposed person promptly
to fresh air. If breathing has stopped, perform artificial respiration. Keep the affected
person warm and at rest. Get medical attention as soon as possible.
Eye Contact: 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: 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 thy seem.
Ingestion: If conscious, give the exposed person large quantities of water immediately.
Do
NOT induce vomiting. 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: Contact with strong acids will product
hydrogen fluoride. Avoid extreme temperatures, such as fires, they will cause decomposition
and formation of hydrofluoric acid and fluorine.
Hazardous Decomposition Products: Extreme temperatures, such as fires, will cause
decomposition and formation of hydrofluoric acid and fluorine.

Special Fire Fighting Procedures and Precautions: Although this chemical is not
flammable, when heated to temperatures such as fire, it will release hydrogen fluoride gas.
Auto Ignition Temperature: N/A
Unusual Fire and Explosion Hazards: 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, as in a fire, it will
decompose, releasing highly toxic hydrogen fluoride gas.
