4. FIRST AID MEASURES
For advice, contact a Poisons Information Centre (e.g. phone Australia 131 126; New Zealand 0800 764 766) or a
doctor at once.
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.
Eye Contact:
Immediately wash in and around the eye area with large amounts of water for at least 15 minutes. Eyelids to be held
apart. Remove clothing if contaminated and wash skin. Urgently seek medical assistance. Transport promptly to
hospital or medical centre. Continue to wash with large amounts of water until medical help is available.
Ingestion:
Immediately rinse mouth with water. If swallowed, do NOT induce vomiting. Give a glass of water. Seek immediate
medical assistance.
Indication of immediate medical attention and special treatment needed:
Treat symptomatically. Material is corrosive. Can cause corneal burns. Can cause pulmonary oedema. Effects may be
delayed.

5. FIRE FIGHTING MEASURES
Suitable Extinguishing Media:
Not combustible, however, if material is involved in a fire use: Fine water spray, normal foam, dry agent (carbon
dioxide, dry chemical powder).
Hazchem or Emergency Action Code: 2X
Specific hazards arising from the substance or mixture:
Non-combustible material.
Special protective equipment and precautions for fire-fighters:
Decomposes on heating emitting toxic fumes, including those of hydrogen fluoride . Fire fighters to wear
self-contained breathing apparatus and suitable protective clothing if risk of exposure to products of decomposition.
6. ACCIDENTAL RELEASE MEASURES
Emergency procedures/Environmental precautions:
Clear area of all unprotected personnel. If contamination of sewers or waterways has occurred advise local
emergency services.
Personal precautions/Protective equipment/Methods and materials for containment and cleaning up:
Slippery when spilt. Avoid accidents, clean up immediately. Wear protective equipment to prevent skin and eye
contact and breathing in vapours. Work up wind or increase ventilation. 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.
7. HANDLING AND STORAGE
Precautions for safe handling: Avoid skin and eye contact and breathing in vapour, mists and aerosols. Always add
the acid to water, never the reverse. Not to be available except to authorised or licensed persons.
Conditions for safe storage, including any incompatibilities: Keep locked up. Keep away from children and
animals. Store in a cool, dry, well ventilated 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
Workplace Exposure Standards: No value assigned for this specific material by the New Zealand Workplace
Health & Safety Authority. However, Workplace Exposure Standard(s) for related component(s):
Fluorides, as F: WES-TWA 2.5 mg/m3, bio
Hydrogen fluoride, as F: Ceiling 3 ppm, 2.6 mg/m3
Product Name: HYDROFLUOROSILICIC ACID
Issued: 07/05/2015
Substance No: 000000015539
Version: 4

Safety Data Sheet
As published by the New Zealand Workplace Health & Safety Authority.
WES - TWA (Workplace Exposure Standard - Time Weighted Average) - The eight-hour, time-weighted average
exposure standard is designed to protect the worker from the effects of long-term exposure.
'bio' - Biological Exposure Index.
WES - Ceiling (Workplace Exposure Standard - Ceiling). A concentration that should not be exceeded during any part
of the working day.
These Workplace 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 workplace 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.
Appropriate engineering controls:
Ensure ventilation is adequate and that air concentrations of components are controlled below quoted Workplace
Exposure Standards. Keep containers closed when not in use.
If in the handling and application of this material, safe exposure levels could be exceeded, the use of engineering
controls such as local exhaust ventilation must be considered and the results documented. If achieving safe exposure
levels does not require engineering controls, then a detailed and documented risk assessment using the relevant
Personal Protective Equipment (PPE) (refer to PPE section below) as a basis must be carried out to determine the
minimum PPE requirements.
Individual protection measures, such as Personal Protective Equipment (PPE):
The selection of PPE is dependent on a detailed risk assessment. The risk assessment should consider the work
situation, the physical form of the chemical, the handling methods, and environmental factors.
OVERALLS, CHEMICAL GOGGLES, FACE SHIELD, GLOVES (Long), APRON, RUBBER BOOTS.
Wear overalls, chemical goggles, face shield, elbow-length impervious gloves, splash apron or equivalent chemical
impervious outer garment, 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 determined by a risk assessment an inhalation risk exists, wear a suitable mist respirator meeting the requirements
of AS/NZS 1715 and AS/NZS 1716.
