3. Hazards Identification
EMERGENCY OVERVIEW
Non-flammable translucent white to pale yellow solid and gas with hydrogen fluoride odour. Poison gas and
solid. Can cause severe irritation and burns to the eyes, skin, and mucous membranes. Inhalation can cause
severe respiratory irritation, chemical pneumonitis and dangerous retention of body fluid in the lungs (oedema).
Effects may be delayed. Decomposes to form additional hydrogen fluoride, when heated or on contact with
moisture. Repeated overexposure to fluorides may have long-term health effects. Exposure is not expected
under normal working conditions as this electrolyte is contained in an enclosed system. The following health
information is provided for accidental releases.
Eye Effects: Contact may cause severe irritation and burns with lesions and loss of vision.
Skin Effects: Causes severe skin irritation. Irritation and burns may be delayed. Contact with wet skin
may cause severe irritation and corrosive burns. Burns are progressive while any residual
active fluorides remain.
Ingestion/ Oral Solid is expected to react with stomach acid to produce highly corrosive hydrogen fluoride.
Effects: Ingestion may cause nausea, vomiting, diarrhoea, and abdominal pain. Ingestion of
fluorides may cause circulatory or respiratory failure and death. Effects may be delayed.
Inhalation Effects: May cause severe respiratory irritation accompanied by coughing, burning sensation,
difficulty breathing and life-threatening fluid retention and swelling in the lungs (oedema).
Repeated exposure may cause chronic bronchitis or other long-term health effects (See

Section 11).
Extended Effects Extended low level systemic absorption of fluoride may cause fluorosis, an abnormal
calcification pattern of the skeletal system. Prolonged repeated exposure may cause
changes in the bone and chronic respiratory irritation, congestion, and impairment.
Medical Conditions Irritant properties may aggravate pre-existing eye, skin, and respiratory conditions.
Aggravated By Individuals suffering from diabetes or kidney problems may be more susceptible to the
Exposure: effects of fluoride.

4. First Aid Measures
Immediately flush eyes with lukewarm water for at least 15 minutes occasionally opening
Eyes:
and closing upper and lower lid to ensure adequate flushing. Continue flushing while
obtaining immediate medical attention.
Remove contaminated clothing as rapidly as possible while flushing affected area with
Skin:
copious quantities of water. Seek immediate medical attention. Dermal burns may be
treated with a calcium gluconate gel or slurry in water or glycerine. This compound binds
the active fluorides in an insoluble form and limits burn extension and relieves pain.
Administer 1-2 glassfuls of milk, calcium gluconate, or calcium lactate to bind fluoride ion in
Ingestion/Oral:
the gastrointestinal tract. Never give anything by mouth to an individual that is or could
rapidly become unconscious. Get immediate medical attention.
PROMPT MEDICAL ATTENTION IS MANDATORY IN ALL CASES OF OVEREXPOSURE.
Inhalation:
RESCUE PERSONNEL SHOULD BE EQUIPPED WITH SELF-CONTAINED BREATHING
APPARATUS. Victims should be assisted to an uncontaminated area and inhale fresh air.
Quick removal from the contaminated area is most important. If breathing is difficult,
administer oxygen. If breathing has stopped administer artificial resuscitation and
supplemental oxygen. Further treatment should be symptomatic and supportive. Assure
that mucous or vomited material does not obstruct the airway by use of positional drainage.
Delayed pulmonary oedema may occur. Keep patient under medical observation for at
Other Information:
least 48 hours.

for Fire Fighters:
clothing as necessary to prevent exposure. Runoff waters from firefighting are
corrosive. Prevent entry into waters and sewers.
For Flammability Properties - see Section 9
6. Accidental Release Measures
Immediately evacuate all personnel from affected area. Ventilate area of leak. Use appropriate protective
equipment (See Section 8). Deny entry to unauthorised or unprotected individuals. Do not walk through or
otherwise scatter spilled material.
7. Handling and Storage
Handling: Do not eat, drink, smoke, apply cosmetics or store personal items in work and storage areas. Wear
chemical resistant suit, gloves, chemical type goggles and resistant boots. Use appropriate respiratory
protection and avoid breathing fumes. Emergency shower, eye wash bottles and calcium gluconate
gel should be available.
Storage: Keep container dry. Keep in a cool, well-ventilated place. Keep away from heat and sources of ignition

11. Toxicological Information
For a comprehensive description for the various toxicological (health) effects that may arise if the user comes into
contact with the substance or preparation refer to Section 3 Hazards Identification.
INHALATION: Inhalation may cause irritation and pulmonary oedema. Repeated inhalation may have chronic
effects (See Section 3). A 1-hour LC50 of 966 (rat) has been cited for hydrogen fluoride. CGA lists the 鈥渁verage鈥?
1-hour LC50 for hydrogen fluoride in the rat as 1300 ppm.
INGESTION: Causes severe burns and tissue destruction. Adverse effects systemic effects are similar to those
following inhalation. Burns may be delayed.
SKIN AND EYE: Can cause severe burns and tissue destruction. Dilute hydrofluoric acid solutions that caused
little or no irritation at the time of exposure have caused severe and painful burns several hours later.
Animal Data:
LD50 value: LD50: No Data
LC50: 1300ppm
LC50 value:
Inhalation/rat
(1H average 鈥? CGA P-20, 1995)
Ninety-six-hour LC50s for fluoride in freshwater fish range from 51 mg/litre in the rainbow trout
(oncorhynchus mykiss) to 460 mg/litre in the threespine stickleback (Gasterosteus aculeatus).
Al 96-hour acute toxicity tests on marine fish gave results greater than 100 mg/litre.
