Advice to Doctor
Treat symptomatically
SECTION 5 ?FIRE FIGHTING MEASURES
Fire/Explosion Hazards
Dangerous decomposition or Combustion Products
Thermal decomposition
Extinguish fire with foam and water spray. If area is heavily exposed to fire and if conditions permit let fire
burn itself out since water may increase the contamination hazard. Fine dust dispersed in air (particularly in
confined spaces) may ignite if exposed to high temperature ignition source. Fire fighters to wear full
protective clothing such and self contained breathing apparatus
Hazardous decomposition products
None known
Hazardous reactions
None known
Extinguishing Media
Extinguish fire with foam and water spray
SECTION 6 ?ACCIDENTAL RELEASE MEASURES
Spills and Disposal
DO NOT contaminate streams, rivers or waterways with the chemical or used containers. Pick up bulk
material by sweeping or other effective means and place into drums. Do not flush with water. If spill area is
on ground near trees or other valuable plants remove top 15cm of soil after initial cleanup. Should product
contact soil apply activated charcoal. Activated charcoal will absorb but not completely neutralise the
product. Cleanup crew should wear rubber gloves, protective clothing, boots and eye goggles. Dispose of by
burying in an approved landfill site.
Disposal
(1) After intended use:
Shake empty into application equipment. Destroy empty bags by puncturing or shredding them. Dispose
of empty bags at a local authority landfill. If no landfill is available, bury the containers below 500 mm in
a licensed/ approved disposal site. Empty containers and product should not be burnt.
(2) After spill or accident
Dispose of sealed containers at approved local waste disposal site.
SECTION 7 ?HANDLING AND STORAGE
Storage and Transport
Keep container tightly closed. Store in a cool and ventilated area away from foodstuffs. During storage keep
from contact with fertilisers, other pesticides and seeds. Store in the closed original container in a well-
ventilated area, as cool as possible but out of direct sunlight.
This product is not a dangerous good

SECTION 11 ?TOXICOLOGICAL INFORMATION
Health Effects
Acute: Swallowed: No LD50 information is available for the formulated product.
Details for the active constituents are as follows:
Low toxicity through this route
Acute oral LD50 rat: 1690 mg/kg (hexazinone)
Acute oral LD50 rat: > 1869-3080 mg/kg (atrazine)
Eye: A severe eye irritant (due to hexazinone component). May cause
conjunctivitis, mild to moderate corneal clouding and moderate iritis.

May cause skin irritation.
Inhaled: Low toxicity through this route. May cause irritation.
Chronic: None established for formulated product.
Hexazinone:
At high levels (1250 ppm active ingredient) dog studies show growth retardation and evidence of anaemia.
No evidence of mutagenicity. teratogenicity or oncogenicity.
Atrazine:
Atrazine technical has been extensively tested in laboratory animals and in test tube systems. No evidence
of mutagenic, teratogenic or reproductive effects was obtained. After chronic administration a slight increase
in the evidence of mammary tumours was reported in one species (rat) one sex (female) and one strain
(Sprague Dawley) at higher doses. The relevancy of these findings to humans is heavily doubted. Atrazine
has been listed by IARC as a Class 2B suspected carcinogen (ie a possible human carcinogen).
Atrazine has demonstrated the potential to contaminate ground and surface water. To minimise the entry to
ground and surface water the following recommendations are made:
Do not use in irrigation channels or in drains where water is discharged onto pasture land or crop land.
Do not empty equipment in above situations.
Do not apply within 60m of a recognised waterway or dam.
Do not load or apply within 20m of any well, sink hole, intermittent or perennial stream or river.
SECTION 13 - DISPOSAL CONSIDERATIONS
Do not dispose of undiluted chemicals on site. Puncture or shred and bury empty containers at a local
authority landfill. If no landfill is available, bury the containers below 500mm in a disposal pit specifically
marked and set up for this purpose clear of waterways, desirable vegetation and tree roots. Empty
containers and product should not be burnt.
