HAZARD IDENTIFICATION |
Hazardous according to the criteria of
Worksafe Australia
Hazard Category: Toxic, Corrosive
ACUTE HEALTH EFFECTS
Swallowed:
Toxic if swallowed.
Will cause burns to the mouth, mucous membranes,
throat, oesophagus and stomach. May cause headache, nausea and vomiting. If
sufficient quantities are ingested (swallowed) death may occur.
Eye:
Will cause burns to the eyes with effects including:
Pain, tearing, conjunctivitis and if duration of exposure is long enough,
blindness will occur.
Skin:
Will cause burns to the skin, 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 exposure may lead to
irreversible damage to health. 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. Prolonged or repeated skin contact will lead to necrosis (death) of
the skin.
Boric acid has been classified as a CATEGORY 3 TOXIC
TO REPRODUCTION (WORKSAFE).
Substances suspected of impairing fertility and or
possibly causing birth defects. Are those substances which have possible
developmental toxicity effects on humans but in respect of which the available
information is not adequate for making a satisfactory assessment. There is some
evidence from appropriate animal or epidemiological studies, but this is
insufficient to place the substance in Category 2.

FIRST AID MEASURES |
Swallowed:
If swallowed, DO NOT induce vomiting. Seek urgent
medical assistance.
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.
Skin:
If material is splashed onto the skin, remove any
contaminated clothing and wash skin thoroughly with water and soap if
available.
Urgently transport to hospital or doctor.
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 - Administer oxygen if breathing is difficult.
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 or
water spray.
SPECIAL FIRE FIGHTING PROCEDURES: Self-contained breathing apparatus (SCBA)
required for fire-fighting personnel.
Flammability
Material does not burn. Containers may explode when
heated. Runoff may pollute waterways.
Fire will produce irritating, toxic and / or corrosive
gases.
|
6.
ACCIDENTAL RELEASE MEASURES |
EMERGENCY ACTION:
Keep unnecessary people away;
Isolate hazard area and deny entry. Stay upwind; Keep out of low areas. Isolate
for 100 m in all directions if tank, rail car or tanker truck is involved in
fire.
SPILL OR LEAK PROCEDURE:
No flares, smoking or flames in
hazard area as toxic decomposition products may be formed.
Stop leak if you can do it without
risk.
SMALL SPILLS:
Neutralize with lime, soda ash or
crushed limestone. Take up with sand, dirt or vermiculite. Place into 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. Safely stop flow of spill. Bund area. Trained personnel should wear
Personal Protective equipment as highlighted in this MSDS. 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 or flames,
strong alkalis, acids and oxidizing agents. Store in original packages as
approved by manufacturer. Check all fittings, valves, reticulation (piping) and
any ancillary equipment 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.

EXPOSURE CONTROLS / PERSONAL PROTECTION |
Exposure Standards
***************************
STANNOUS FLUOROBORATE
(Worksafe Australia)
[TWA] 2 mg/m³ (Inorganic compounds as Sn )
***************************
FLUOROBORIC ACID
(Worksafe Australia)
[TWA] 2.5 mg/m³ (as Fluoride)
***************************
BORIC ACID
(Worksafe Australia)
[TWA] 5 mg/m³
Engineering Controls
Toxic and corrosive liquid. Single
significant exposure may cause death. Maintain adequate ventilation at all
times. At high temperatures the solution releases a hazardous mist. Prevent
accumulation of vapours or mists in hollows or sumps.
Mechanical ventilation (dilution
and local exhaust), and control of process conditions. Corrosion resistant
materials may be needed where dust, 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: PVC, Nitrile, Neoprene,
Natural rubber or any other type of apron or splash suit as recommended by the
manufacturer.
GLOVES: PVC, Nitrile, Neoprene,
Natural rubber or any other type of glove as recommended by the
manufacturer.
EYES: Chemical goggles or
faceshield to protect eyes.
RESPIRATORY PROTECTION: Avoid
breathing of vapours 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.

boron trifluoride (speculative), fluoride compounds, and may form hydrogen
fluoride in contact with strong acids.

Stannous Fluoborate is acidic and
will react with acid incompatible materials, eg bases, sulfides, cyanides. It
may react vigourosly with strong oxidizing agents. Corrosive to aluminium.
CONDITIONS TO AVOID:
Heat, flames and incompatibles.
