3. HAZARD
IDENTIFICATION |
Hazardous according to the criteria of Worksafe
Australia
Hazard Category: Toxic, Irritant
ACUTE HEALTH EFFECTS
Swallowed:
Will cause severe irritation to the mouth, mucous
membranes, throat, oesophagus and stomach. May result in difficult breathing, stomach
pain and circulatory shock. Toxic if swallowed.
Due to acid in the stomach, hydrofluoric acid will be
released with systemic fluoride poisoning likely with severe and potentially
fatal hypocalcemia.
Eye:
Will cause severe irritation to the eyes, with effects
including: tearing, pain, and stinging. Depending upon duration of exposure,
eye damage may occur.
Skin:
Will cause irritation to the skin, with effects
including; redness, itchiness, and possible dermatitis.
Inhaled:
Dusts may cause irritation to the nose, throat and
respiratory system with effects including: coughing, choking. In severe cases,
inhalation may result in spasm, inflammation and edema of the larynx and
brochi, chemical pneumonitis and pulmonary edema. Extremely destructive to tissue
of the mucous membranes and upper respiratory tract.
Chronic:
This product may cause severe eye irritation and
depending upon duration of exposure, some form of permanent eye damage may
occur. Prolonged or repeated skin contact may lead to dermatitis. Exposure to
fluorides is associated with fluorosis. Kidney damage, asthma and rheumatism
symptoms may occur if exposure standards are exceeded. Chronic effects include
excessive calcium precipitation by the fluoride ion in the bones, ligaments and
tendons. Prolonged or repeated skin contact will lead to necrosis (death) of
the skin.

4. FIRST AID
MEASURES |
Swallowed:
If swallowed, DO NOT induce vomiting. Seek urgent
medical assistance. GIve large quantities of milk or water. Give at least 30 mL
of milk of magnesia or aluminium hydroxide gel in equal amount of water to
react with and reduce the fluoride present. If these are not available, the
whites of 2 to 3 eggs may be used.
Eye:
If crystals enter the eyes, flush with plenty of water
for at least 15 minutes, ensuring eye lids are held open. Immediately transport
to hospital or doctor.
Skin:
If skin contact occurs, remove any contaminated
clothing and wash skin thoroughly with water and soap. Seek medical attention.
Inhaled:
Remove victim to fresh air. Apply resuscitation if
victim is not breathing - DO NOT USE DIRECT MOUTH - TO - MOUTH METHOD if victim
ingested or inhaled substance; use alternative respiratory method or proper
respiratory device -
First Aid Facilities:
Eye wash fountain, safety shower and normal wash room
facilities.
Advice to Doctor:
Treat symptomatically. Symptoms of fluoride
overexposure may include salivation, nausea, vomiting, abdominal pain, fever,
laboured breathing. Fluoride ion can reduce serum calcium levels possibly
causing fatal hypocalcemia. Prolonged exposure to fluoride dusts, vapours or
mists results in perforation of the nasal septum. Chronic effects include
excessive calcium precipitation by the fluoride ion in the bones, ligaments and
tendons.

5. FIRE-FIGHTING
MEASURES |
Fire/Explosion Hazard
EXTINGUISHING MEDIA: Use dry chemical, carbon dioxide, foam,
water spray or water fog.
Bund the area to stop runoff. Minimise the
use of water.
SPECIAL FIRE FIGHTING PROCEDURES: Emits toxic fumes under fire conditions.
Self-contained breathing apparatus (SCBA)
required for fire-fighting personnel.
Use water spray to spray to cool
fire-exposed surfaces and to protect personnel.
Flammability
Not combustible. If involved in a fire may generate
toxic and corrosive fumes.
|
6. ACCIDENTAL
RELEASE MEASURES |
EMERGENCY ACTION:
Keep unnecessary people away;
Isolate hazard area and deny entry.
SPILL OR LEAK PROCEDURE:
Ensure there are no flares, smoking or
flames in hazard area which can cause decomposition and form toxic fumes.
Contain powder and prevent from spreading and entering drains.
SMALL SPILLS:
Take up with sand, dirt or
vermiculite. Place into plastic, clean, labelled drum(s) for later disposal. Neutralize any residues
with lime, or soda ash.
LARGE SPILLS: Notify Emergency Services (Police or Fire
Brigade). Tell them location, nature and any information that would be helpful.
Contain spill. Trained personnel should wear personal protective equipment as
highlighted in this MSDS if dust clouds are formed.
Pump into clean, labelled tanks.
Treat any residues as for SMALL SPILLS.
Consult an expert regarding disposal
of this product.
|
7. HANDLING AND
STORAGE |
Store in a cool place and out of
direct sunlight. Store away from
sources of heat, strong alkalis, acids, combustibles and oxidizing agents.
Store in original packages. Check all containers for leaks. A supplied air
respirator or a Self-Contained Breathing Apparatus (SCBA) for emergencies
should be available and checked regularly. For further information please refer
to the Engineering Controls of this MSDS.

8. EXPOSURE
CONTROLS / PERSONAL PROTECTION |
EExposure Standards
***************************
Fluorides (as F) (which can be formed)
[TWA] 2.5 mg/m³ (Worksafe Australia)
[TWA] 2.5 mg/m³ (American Conference of Govt. Industrial Hygienists)
***************************
Borate, tetra, sodium salt (which can be formed)
[TWA] 1 mg/m3 (Worksafe Australia)
***************************
Engineering Controls
Corrosive, toxic solid. Single significant exposure
may cause severe injury. Maintain adequate ventilation at all times.
Mechanical ventilation (dilution and local exhaust),
and control of process conditions. Corrosion resistant materials may be needed
where acid liquid splashes, mists and fumes may be formed. It may be necessary
to consider process or personnel enclosure
(fully enclosed systems).
If engineering controls and work practices are not
effective in preventing or controlling exposure, then suitable personal
protective equipment, which is known to perform satisfactorily, should be used.
Personal Protection Equipment
CLOTHING: Wear impervious apron and long sleeved
clothing or splash suit as appropriate (e.g. from PVC, Nitrile, Neoprene,
Natural rubber.
GLOVES: Wear impervious gloves (e.g. PVC, Nitrile,
Neoprene, Natural rubber gloves).
EYES: Wear chemical goggles or faceshield to protect
eyes.
RESPIRATORY PROTECTION: Avoid breathing of dusts or
mists. Select and use respirators in accordance with AS/NZS 1715/1716. When
vapours or mists exceed the exposure standards then the use of an
atmosphere-supplied, positive pressure demand self-contained or airline breathing
apparatus supplied air respirator complying with the requirements of AS/NZS
1715 is recommended. Filter capacity
and respirator type depends on exposure levels.
