3. 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.

 

 

 

4. 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.

 

 

 

8. 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.
