3. Hazards identification
Risk Phrases: Causes burns. Risk of serious damage to eyes.
Poisons Schedule: S7 Dangerous Poison.
4. First-aid measures
For advice, contact a Poisons Information Centre (Phone eg. Australia 131 126; New Zealand 0 800 764766) or a doctor.
Inhalation: Remove victim from area of exposure - avoid becoming a casualty. Remove contaminated clothing and
loosen remaining clothing. Allow patient to assume most comfortable position and keep warm. Keep
at rest until fully recovered. If patient finds breathing difficult and develops a bluish discolouration of the
skin (which suggests a lack of oxygen in the blood - cyanosis), ensure airways are clear of any
obstruction and have a qualified person give oxygen through a face mask. Apply artificial respiration if
patient is not breathing. Seek immediate medical advice.
Skin Contact: If skin contact occurs, immediately remove contaminated clothing. Flush skin under running water for
15 minutes. Then apply calcium gluconate gel. Contact the Poisons Information Centre. For skin
burns, cover with a clean, dry dressing until medical help is available.

Material Safety Data Sheet
Eye Contact: If in eyes, hold eyelids apart and flush the eye continuously with running water. Continue flushing
until advised to stop by the Poisons Information Centre or a doctor, or for at least 15 minutes.
Ingestion: Immediately rinse mouth with water. If swallowed, do NOT induce vomiting. Give a glass of water.
Seek immediate medical assistance.
Notes to physician: Treat symptomatically. Effects may be delayed. Can cause corneal burns.
5. Fire-fighting measures
Specific Hazards: Non-combustible material.
Fire-fighting advice: Decomposes on heating emitting toxic fumes, including those of hydrogen fluoride .
Keep containers cool with water spray. Fire fighters to wear self-contained breathing
apparatus and suitable protective clothing if risk of exposure to products of
decomposition.
Suitable Extinguishing Media: Not combustible, however, if material is involved in a fire use: Water fog (or if unavailable
fine water spray), foam, dry agent (carbon dioxide, dry chemical powder).
6. Accidental release measures
Clear area of all unprotected personnel. Wear protective equipment to prevent skin and eye contact and breathing in vapours.
Contain - prevent run off into drains and waterways. Use absorbent (soil, sand or other inert material). Neutralise with lime or
soda ash. Collect and seal in properly labelled containers or drums for disposal. If contamination of sewers or waterways has
occurred advise local emergency services.
7. Handling and storage
Handling advice: Avoid skin and eye contact and breathing in vapour, mists and aerosols. Always add the acid to water,
never the reverse.
Storage advice: Store in cool place and out of direct sunlight. Store away from foodstuffs. Store away from incompatible
materials described in Section 10. Keep dry - reacts with water, may lead to drum rupture. Keep
containers closed when not in use - check regularly for leaks.
8. Exposure controls/personal protection
Occupational Exposure Limits:
No value assigned for this specific material by the National Occupational Health and Safety Commission. However,
Exposure Standard(s) for constituent(s):
Fluorides (as F): 8hr TWA = 2.5 mg/m3
As published by the National Occupational Health and Safety Commission.
TWA - The time-weighted average airborne concentration over an eight-hour working day, for a five-day working week over
an entire working life.
These Exposure Standards are guides to be used in the control of occupational health hazards. All atmospheric
contamination should be kept to as low a level as is workable. These exposure standards should not be used as fine
dividing lines between safe and dangerous concentrations of chemicals. They are not a measure of relative toxicity.

Material Safety Data Sheet
Engineering Control Measures:
Ensure ventilation is adequate and that air concentrations of components are controlled below quoted Exposure
Standards. If inhalation risk exists: Use with local exhaust ventilation or while wearing suitable mist respirator. Keep
containers closed when not in use.
Personal Protective Equipment:
Orica Personal Protection Guide No. 1, 1998: D - OVERALLS, RUBBER BOOTS, FACE SHIELD, SAFETY SHOES,
GLOVES (Long), APRON.
Wear overalls, face shield, elbow-length impervious gloves, splash apron and rubber boots. Always wash hands before
smoking, eating, drinking or using the toilet. Wash contaminated clothing and other protective equipment before storage or re-
use.
If risk of inhalation exists, wear suitable mist respirator meeting the requirements of AS/NZS 1715 and AS/NZS 1716.
