3. Hazards Identification

Emergency Overview
DANGER! MAY BE FATAL IF SWALLOWED OR INHALED. AFFECTS RESPIRATORY
SYSTEM, HEART, SKELETON, CIRCULATORY SYSTEM, CENTRAL NERVOUS
SYSTEM AND KIDNEYS. CAUSED IRRITATION TO SKIN, EYES AND RESPIRATORY
TRACT. IRRITATION EFFECTS MAY BE DELAYED.

Health Rating: 3 Severe (Poison)
Flammability Rating: 0 None
Reactivity Rating: 1 (Slight)
Contact Rating: 2 Moderate
Lab Protective Equipment: Goggles, Lab Coat, Vent Hood, Proper Gloves

Potential Health Effects
If inhaled or swallowed, this compound can cause fluoride poisoning. Early symptoms
include nausea, vomiting, diarrhea, and weakness. Later effects include central nervous
system effects, cardiovascular effects and death.
Inhalation: Causes severe irritation to the respiratory tract, symptoms may include
coughing, sore throat, and labored breathing. May be absorbed through inhalation
of dust; symptoms may parallel those from ingestion exposure. Irritation effects may
not appear immediately.

Ingestion: Toxic! May cause salivation, nausea, vomiting, diarrhea, and abdominal
pain. Symptoms of weakness, tremors, shallow respiration, cardopedal spasm,
convulsions, and coma may follow. May cause brain and kidney damage. Affects
heart and circulatory system. Death may occur from respiratory paralysis. Estimated
lethal dose=5-10 grams.

Skin Contact: Causes irritation, with redness and pain. Solutions are corrosive.
Effects may not appear immediately.

Eye Contact: Eye Irritant! May cause irritation and serious eye damage. Effects may
not immediately appear.

Chronic Exposure: Chronic exposure may cause mottling of teeth and bone damage
(osteosclerosis) and fluorosis. Symptoms of fluorisis include brittle bones, weight
loss, anemia, calcified ligaments, general ill health and joint stiffness.

Aggravation of Pre-existing Conditions: Populations that appear to be at increased
risk from the effects of fluoride are individuals that suffer from diabetes insipidus or some forms
of renal impairment.

4. First Aid Measures

First Aid procedures should be pre-planned for fluoride compound emergencies.

Inhalation: If inhaled, remove to fresh air. If not breathing, give artificial respiration.
If breathing is difficult, give oxygen. CALL A PHYSICIAN IMMEDIATELY.

Ingestion: Administer milk, chewable calcium carbonate tablets or milk of magnesia. Never
give anything by mouth to an unconscious person. CALL A PHYSICIAN IMMEDIATELY.

Skin Contact: Wipe off any excess material from skin and then immediately flush skin
with large amounts of soapy water. Remove contaminated clothing and shoes. Wash
clothing before re-use. Apply bandages soaked in magnesium sulfate. CALL A
PHYSICIAN IMMEDIATELY.

Eye Contact: Immediately flush eyes with gentle but large stream of water for at least
15 minutes, lifting lower and upper eyelids occasionally. CALL A PHYSICIAN
IMMEDIATELY.

Note to Physician: For large exposures, systemic effects (hypocalcaemia and hypo-
magnesia) may occur.
5. Fire Fighting Measures

Fire: Not considered to be a fire hazard.
Explosion: Not considered to be an explosion hazard.
Fire Extinguishing Media: Use any means suitable for extinguishing surrounding fire.
Special Instructions: In the event of a fire, wear full protective clothing and NIOSH-approved
self-contained breathing apparatus with full face-piece operated in the pressure demand or other
positive pressure mode.

6. Accidental Release Measures

Ventilate area of leak or spill. Wear appropriate personal protective equipment as
specified in Section 8. Spills: Pick up and place in a suitable container for reclamation or
disposal, using a method that does not generate dust. US Regulations (CERCLA)
require reporting spills and releases to soil, water and air in excess of reportable quantities.
The toll free number for the US Coast Guard National Response Center is 800-424-8802.

7. Handling and Storage

Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against
physical damage. Separate from acids and oxidizing materials. Containers of this
material may be hazardous when empty since they retain product residues (dusts,
solids); observe all warnings and precautions listed for the product.

8. Exposure Controls / Personal Protection

Airborne Exposure Limits:
-OSHA Permissible Exposure Limit (PEL): 2.5 mg(F)/m3 (TWA)

-ACGIH Threshold Limit Value (TLV): 2.5 mg(F)/m3 (TWA)


Ventilation System: A system of local and/or general exhaust is recommended to keep
employee exposures below the Airborne Exposure Limits. Local exhaust ventilation
is generally preferred because it can control the emissions of the contaminant at its
source, preventing dispersion of it into the general work area. Please refer to the
ACGIH document, Industrial Ventilation, A Manual of Recommended Practices, most
recent edition, for details.

Personal Respirators (NIOSH Approved): If the exposure limit is exceeded, a half-face
dust/mist respirator may be worn for up to ten times the exposure limit or the maximum
use concentration specified by the appropriate regulatory agency or respirator supplier,
whichever is lowest. A full-face piece dust/mist respirator may be worn up to 50 times
the exposure limit, or the maximum use concentration specified by the appropriate
regulatory agency, or respirator supplier, whichever is lowest. For emergencies or
instances where the exposure levels are not known, use a full-facepiece positive-
pressure, air-supplied respirator.
Skin Protection: Wear impervious protective clothing, including boots, gloves, lab coat,
apron or coveralls, as appropriate, to prevent skin contact.

Eye Protection: Use chemical safety goggles and/or full face shield where dusting or
splashing of solutions is possible. Maintain eye wash fountain and quick-drench
facilities in work area.
