3. HAZARD
IDENTIFICATION |
Hazardous according to the criteria of
Worksafe Australia
Hazard Category: Toxic, Corrosive
ACUTE HEALTH EFFECTS
Swallowed:
Will cause severe burns 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:
Vapours will irritate the eyes and cause tearing. The
liquid will cause severe burns to the eyes with possible permanent corneal
damage and blindness.
Skin:
Will cause severe irritation and will cause burns to
the skin (if not removed promptly), with effects including: redness,
blistering, localised pain and dermatitis.
Inhaled:
Will cause severe irritation to the nose, throat and
respiratory system with effects including: coughing wheezing, laryngitis,
shortness of breath. 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:
Prolonged or repeated skin contact may lead to skin
death (necrosis). 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.

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 material is splashed into eyes,
flush with plenty of water for at least 15 minutes, ensuring eye lids are held
open. Immediately transport to hospital or doctor. Examine the eyes for possible
corneal damage.
Skin:
If material is splashed onto the
skin, 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.
UNUSUAL FIRE AND
EXPLOSION HAZARDS: If tanks, drums or containers of this material are heated,
they may rupture and project corrosive liquids over a wide area.
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.
Stop leak if you can do it without risk. Contain and prevent from spreading and
entering drains.
SMALL SPILLS:
Neutralize with lime, soda ash or
crushed limestone. Take up with sand, dirt or vermiculite. Place into plastic,
clean, labelled drum(s) for later
disposal.
LARGE SPILLS: Notify Emergency Services (Police or Fire
Brigade). Tell them location, nature and any information that would be helpful.
Contain spill. If possible safely stop flow of spill. Bund area. Trained
personnel should wear personal protective equipment as highlighted in this
MSDS.
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 as approved by manufacturer. Check all fittings,
valves, reticulation (piping) and any ancillary equipment for leaks.
Toxic and corrosive fumes may be
released. 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 |
Exposure Standards
***************************
Fluorides (as F) (which can be formed)
[TWA] 2.5 mg/m³ (Worksafe Australia)
[
***************************
Borate, tetra, sodium salt (which can be formed)
[TWA] 1 mg/m3 (Worksafe Australia)
***************************
Engineering Controls
Corrosive and toxic liquid. Single significant
exposure may cause severe injury. Maintain adequate ventilation at all times.
Prevent accumulation of fumes in hollows or sumps.
Engineering controls include process or personnel
enclosure (fully enclosed systems),
mechanical ventilation (dilution and local exhaust), and control of process
conditions. Corrosion resistant materials will be needed for liquid splashes,
mists and fumes.
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 gases.
Select and use respirators in accordance with AS/NZS 1715/1716. When the
concentration of airborne contaminants reach the exposure standards then the
use of a half-face respirator with acid vapour cartridge is recommended. For
high concentration use a 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.
If entering spaces where the airborne concentration of
a contaminant is unknown then the use of a Self-contained breathing apparatus
(SCBA) with positive pressure air supply complying with AS/NZS 1715 / 1716, or
any other acceptable International Standard is recommended. The use of fully-encapsulating, gas-tight
suits is also recommended.
