Chronic:

Prolonged or repeated exposure may lead to irreversible damage to health. Prolonged or repeated exposure may lead to permanent irreversible injury.

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.

Lead containing compounds are classified as a CATEGORY 1 TOXIC TO REPRODUCTION (WORKSAFE).

Established human reproductive hazards are those substances known to be reproductive hazard.There is sufficient evidence to establish a casual association between human exposure to these substances and the development of birth defects.

Lead containing compounds are classified as a CATEGORY 3 TOXIC TO REPRODUCTION (WORKSAFE).

Substances suspected of impairing fertility. 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.

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.

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.
