| Other ingredients | Non hazardous | 60-100% |

4) FIRST AID MEASURES

If poisoning occurs, move out of dangerous area immediately contact a doctor or Poison
Information Centre (Ph: 13 11 26) and follow the advice given.
Show this Safety Data Sheet to the doctor.

If inhaled: If symptoms of poisoning become evident, contact a Poisons Information
Centre, or call a doctor at once. Remove source of contamination or move
victim to fresh air and keep at rest. If breathing is difficult, oxygen may be
beneficial if administered by trained personnel, preferably on a doctor’s
advice. DO NOT allow victim to move about unnecessarily. Symptoms of
pulmonary oedema can be delayed up to 48 hours after exposure.

In case of skin
contact:
Carefully remove contaminated clothing and shoes immediately. Wash gently
and thoroughly affected areas with mild soap and plenty of water for 10-20
minutes or until product is removed.

In case of eye
contact:
No effects expected. If irritation does occur, check and remove any contact
lenses. Protect unharmed eye. Rinse eyes immediately with clean water for at
least 5 minutes. Keep eye wide open while rinsing. Obtain medical advice if
irritation becomes painful or lasts more than a few minutes.

If swallowed: If swallowed, do NOT induce vomiting. Wash mouth with water and contact a
Poisons Information Centre, or call a doctor.

First Aid facilities Ensure eye wash and safety shower are available.

Medical
Attention:
Symptoms may be delayed. The first aid procedure should be established in
consultation with a doctor responsible for industrial medicine.

5) FIRE FIGHTING MEASURES

Extinguishing media Not combustible. Use extinguishing measures that are appropriate to local
circumstances and the surrounding environment.
Hazard from
combustion
products
Not combustible.
Precautions for
fighting fires
Fire fighters should wear full protective gear, including self-contained
breathing apparatus (AS/NZS 1715/1716). Keep unnecessary people away. If
it can be done safely remove intact containers from the fire. Bund area with
sand or earth to prevent contamination of drains or waterways. Dispose of
fire residues and contaminated fire extinguishing water in accordance with
local regulations. Do not release contaminated water into the environment.
Hazchem Code 2X

6) ACCIDENTAL RELEASE MEASURES

Avoid contact with spilled material or contaminated surfaces. Do not smoke, eat or drink during the
clean up process. Wear personal protective clothing and equipment as detailed in Section 8
PERSONAL PROTECTION. Keep people and animals away. Ensure adequate ventilation. Contain
spill and absorb with earth, sand, clay or other absorbent material. Prevent spilled material from
entering drains or watercourses. Collect and store in properly labelled drums for safe disposal. Clean
floor with a damp cloth and place it in the drum. Seal drums and label ready for safe disposal. Deal
with all spillages immediately. If contamination of drains, streams, watercourses etc is unavoidable
warn the local water authority.

7) HANDLING AND STORAGE

Handling Keep out of reach of children. Will irritate eyes and skin. Avoid contact with eyes
and skin. Do not inhale spray mist. After use and before eating, drinking or smoking
wash hands, arms and face thoroughly with soap and water. After each day’s use
wash gloves and contaminated clothing.
Storage Store in the closed original container in a cool well ventilated area. Do not store for
prolonged periods in direct sunlight. Store in a locked room away from children,
animals, food, animal feed, seed and fertilisers.

8) EXPOSURE CONTROL/PERSONAL PROTECTION

| Exposure Standards | TWA (mg/m³) | STEL (mg/m³) |
| :--- | :--- | :--- |
| | 0.05 as arsenic | Not set |

Exposure standard – Time Weighted Average (TWA) means the average
airborne concentration of a particular substance when calculated over a normal
eight hour working day, for a five-day working week.
Short Term Exposure Limit (STEL) means the
exposure level that may be equalled (but should not be exceeded for no longer
than 15 minutes and should not be repeated more than 4 times per day. There
should be at least 60 minutes between successive exposures at the STEL.

Biological Limit
Values
