Section II
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.

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:
New Jersey "Right to Know" laws - Yes
Toxic Substances Control Act Inventory of Toxic Substances (TSCA) - Yes
Workplace Hazardous Materials Information System (WHMIS) - Yes
OSHA Health Hazard Classification: Toxic.
Primary Route(s) of Entry: Eye and skin contact, inhalation
Symptoms of Exposure:
Acute: Fluoride dust may cause irritation to eyes and respiratory tract.
Swallowing fluoride dust may cause nausea, vomiting, abdominal pain or burning, diarrhea,
shortness of breath, difficulty in speaking, thirst, weakness of pulse, disturbed color vision,
muscular weakness, convulsions, loss of consciousness and death. Kidney injury and bleeding
from injury may occur.
Chronic: Repeated exposure above the PEL or TLV to fluoride dust may cause excessive
calcification of ligaments of the ribs, pelvis and spinal column. Sclerosis of changes of
bones and ligaments can be seen by x-ray. Enzyme system effects and pulmonary fibrosis are
reported. Stiffness and limitation of motions may result. Common findings are eye, skin, and
mucous membrane irritation, loss of weight, anorexia, anemia, wasting, cachexia, and dental defects.
Repeated or prolonged exposure to the skin may cause skin rash.
Aggravated Medical Condition: Pre-existing respiratory diseases including
asthma and emphysema.
toxic Data: 125 mg/kg (Oral - Rat)
Section IV
EMERGENCY AND FIRST AID PROCEDURES
Inhalation: If a person breathes in chemical dust, 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 breath easily by themselves. 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.

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.
