4. FIRST AID MEASURES
Eye
If in eyes, hold eyelids apart and flush the eye continuously with running water. Continue flushing until advised to stop
by the Poison Information Centre or a doctor, or for at least 15 minutes.
Inhalation
If inhaled, remove from contaminated area. Apply artificial respiration if not breathing.
Skin
If skin or hair contact occurs, remove contaminated clothing and flush skin and hair with running water.
Ingestion
For advise, contact a Poison Information Centre on 13 11 26 (Australia Wide) or a doctor at once.
Advice to Doctor
Treat symptomatically.
5. FIRE FIGHTING MEASURES
Flammability
Non flammable. May evolve toxic gases (phosphorus oxides) when heated to decomposition.
Fire and Explosion
Non flammable. If product is present in a fire, toxic gases (phosphorus oxides) may be evolved. Evacuate area and
contact emergency services. Remain upwind and notify those downwind of hazard. Wear full protective equipment
including Self Contained Breathing Apparatus (SCBA) when combating fire. Use waterfog to cool intact containers and
nearby storage areas.
Extinguishing
Non flammable.

6. ACCIDENTAL RELEASE MEASURES
Spillage
If spilt (bulk), wear dust-proof goggles, PVC/rubber gloves and a Class P1 (Particulate) respirator (where a dust
inhalation risk exists). Ventilate spillage area. Collect and place in sealable containers for disposal. Avoid generating
dust.
7. STORAGE AND HANDLING
Storage
Store in cool, dry, well ventilated area, removed from oxidising agents, acids and foodstuffs. Ensure product is
adequately labelled. This product when stored in a confined are, unventilated space/hold can give off ammonia or
other odour and lead to the depletion of oxygen within this space and other confined spaces. Do not allow to come in
contact with water, either from rain, condensation or the surface on which stored. Store away from farm chemicals,
e.g. insecticides, fungicides and herbicides.
Handling
Before use carefully read the product label. Use of safe working practices is recommended to avoid eye or skin
contact and inhalation. Observe good personal hygiene, including washing of hands before eating. Prohibit eating,
drinking and smoking in contaminated areas.
8. EXPOSURE CONTROLS/PERSONAL PROTECTION
Exposure Standards
No exposure standard(s) allocated.
Biological Limits
No biological limit allocated.
Engineering Controls
Ensure adequate natural ventilation. Avoid inhalation. Maintain dust levels below the recommended exposure
standard.
PPE
Wear dust-proof goggles and rubber or PVC gloves. When using large quantities or where heavy contamination is
likely, wear: coveralls. Where an inhalation risk exists, wear: a Class P1 (Particulate).

10. STABILITY AND REACTIVITY
Chemical Stability
Stable under recommended conditions of storage.
Conditions to Avoid
Avoid heat, sparks, open flames and other ignition sources.
Material to Avoid
Incompatible with oxidising agents (e.g. peroxides) and acids (e.g. hydrochloric acid).
Decomposition
May evolve toxic gases (phosphorus oxides, sulphur/ nitrogen oxides, ammonia) when heated to decomposition. May
also evolve toxic nitrogen oxides and ammonia when heated to decomposition.
Hazardous Reactions
Polymerization is not expected to occur.
11. TOXICOLOGICAL INFORMATION
Health Hazard Summary
Low toxicity. This product may only present a hazard with eye contact, prolonged and repeated skin contact or with
dust inhalation at high levels.
Eye
Irritant. Contact may result in irritation, lacrimation, pain and redness
