Suitable extinguishing media: If involved in a fire, the product will not burn. Choose extinguishing media to suit the burning material. Water, foam, carbon dioxide or dry chemical. Hazards from Combustion Products: Keep upwind. This product, or spray solutions of this product, react with galvanised steel or unlined steel (except stainless steel) containers and tanks, to produce hydrogen gas which may form a highly flammable or explosive gas mixture. If involved in a major fire, could evolve oxides of nitrogen or phosphorus. Special Protective Equipment for fire fighters: Breathable air apparatus may have to be worn if material is involved in fires especially in confined spaces. Other Information: STOP FIRE WATER FROM ENTERING DRAINS OR WATER BODIES.

6. Accidental Release Measures

Spills & Disposal: Contain spill and absorb with clay, sand, soil or proprietary absorbent (such as vermiculite). Collect in sealed open top containers for disposal. Final clean-up with degreasing agent or detergent is advised. Environmental Precautions: Prevent from entering drains, waterways or sewers.

Personal Protective Equipment: When opening the container, preparing the spray and using the prepared spray, wear cotton overalls buttoned to the neck and wrist (or equivalent clothing) and a washable hat, nitrile or elbow-length PVC gloves and face shield or goggles. Hygiene Measures: After each day's use, wash contaminated clothing and safety equipment. After use and before eating, drinking or smoking, wash hands, arms and face thoroughly with soap and water. Requirements Concerning Special Training: Check State or Territory regulations that require people who use pesticides in their job or business to have training in the application of the materials.

9. Physical and Chemical Properties

Form: Liquid Appearance: Green viscous liquid Odour: Slight ammonia odour. Melting Point: N/A Boiling Point: >105°C Solubility in Water: Soluble in water. Specific Gravity: 1.29 @ 20°C pH: 5.1 Volatile Component: N/A Flash Point: None Flammability: Non combustible material.

10. Stability and Reactivity

Incompatible Materials: Corrosive to mild steel, galvanised steel and zinc. Non corrosive to stainless steel, polyethylene and plastics. Do not mix, store or apply the product or spray solutions of the product in galvanised steel or unlined steel (except stainless steel) containers or spray tanks. Possibility of hazardous reactions: Avoid contact of the concentrate with strong alkalis and alkaline materials such as lime. Such contact may release ammonia vapour with a strong characteristic odour, which is an irritant to eyes. Ammonia is moderately toxic, with a TLV of 25ppm (TWA) or 17mg/m3 which has been set. Hazardous Polymerization: Hazardous polymerisation is not possible.

11. Toxicological Information

Toxicology Information: No harmful effects are expected if the precautions on the label and this SDS are followed. Acute Toxicity - Oral: LD50 (rat) >5000 mg/kg for a similar formulation Acute Toxicity - Dermal: LD50 (rabbits) >5000 mg/kg for a similar formulation Ingestion: The concentrate is of low toxicity if swallowed. Amounts swallowed incidental to normal handling procedures and use are not expected to cause injury. Possible symptoms of exposure include: nausea, vomiting and gastrointestinal discomfort and diarrhoea. Ingestion of a large quantity of the undiluted product may result in hypotension and pulmonary oedema. Inhalation: When applying the product as a spray avoid breathing in spray mist. May cause irritation to mucous membranes and respiratory tract. Skin: The concentrated product may cause slight irritation on contact. Prolonged contact is likely to result in irritation.

Eye: The concentrate may cause irritation of the eyes. Prolonged contact with the concentrate may cause damage to the eye. Carcinogenicity: The Australian Pesticide and Veterinary Medicine Authority (APVMA) and other regulatory agencies classify glyphosate as non-carcinogenic based on the weight-of-evidence. In 2015 the International Agency for Research on Cancer (IARC) concluded that glyphosate was probably carcinogenic to humans. This finding was considered by the APVMA in its 2016 review (1). Chronic Effects: No information available, no chronic effects expected. Serious eye damage/irritation: The product is an eye irritant. Skin corrosion/irritation: The product is a skin irritant. Other Information: The Australian Acceptable Daily Intake (ADI) for glyphosate for a human is 0.3 mg/kg/day, set for the public for daily, lifetime exposure. This is based on the NOEL of 30 mg/kg/day, the level determined to show no effects during long term exposure for the most sensitive indicators and the most sensitive species. (Ref: Aust Govt Dept. of APVMA, 'ADI List', Edition 3/2021).

12. Ecological Information

Persistence and degradability: Adsorption studies indicate that glyphosate has very low mobility. Average field half life of glyphosate is 47 days. Known Harmful Effects on the Environment: Harmful to fish and other aquatic organisms (mainly due to the surfactant). Other Precautions: Do not spray in high winds. Do not contaminate dams, waterways or sewers with this product. Environmental Protection: Glyphosate is a non-selective contact herbicide. Spray drift can cause damage. Acute Toxicity - Fish: The following is data for a similar product. LC50 (96hr) for rainbow trout is 3.13 mg/l. TL50 (96hr) carp is 19.7 ppm Acute Toxicity - Daphnia: EC50 (48hr) for daphnia magna is 8.0 mg/l. Acute Toxicity - Algae: EC50 for 72hrs is 0.124 mg/l for Selenastrum capricornutum Acute Toxicity - Other Organisms: The following data is for the active ingredient, glyphosate. Birds: Not toxic to birds. LD50 for bobwhite quail is >3850 mg/kg Bees: Not toxic to bees. LD50 >100 µg/bee.

13. Disposal Considerations

Product Disposal: On site disposal of the concentrated product is not acceptable. Ideally, the product should be used for its intended purpose. If there is a need to dispose of the product, approach local authorities who hold periodic collections of unwanted chemicals (ChemClear®). Container Disposal: Triple or preferably pressure rinse containers before disposal. Add rinsings to the spray tank. Do not dispose of undiluted chemicals on site. If recycling, replace cap and return clean containers to recycler or designated collection point. If not recycling, break, crush or puncture and deliver empty packaging for appropriate disposal at an approved waste management facility. If an approved waste management facility is not available, bury the empty packaging 500mm below the surface in a disposal pit specifically marked and set up for this purpose clear of waterways, desirable vegetation and tree roots, in compliance with relevant local, state or territory government regulations. Returnable containers: empty contents fully into application equipment. Replace cap, close all valves and return to the point of supply for refill or storage. Empty containers and product should not be burnt.
