3. Hazards Identification

Toxicity - This product is unlikely to present a hazard during normal use

(WHO Class III) Swallowed: low toxicity Tests on rats indicate a low toxicity

following single doses of undiluted product. (LD50 = 2675 mg/kg) Dermal absorption: low toxicity Tests on rats indicate a slight toxicity due to

skin contact with undiluted product. (LD50 >3100 mg/kg)

4. First Aid Measures

Inhalation: Remove victim from 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. Seek medical advice if effects persist.

Skin contact: If skin or hair contact occurs, immediately remove

contaminated clothing and flush skin and hair with running water. Continue

flushing with water until advised to stop by the Poisons Information Centre or

a Doctor; or for 15 minutes and transport to Doctor or Hospital.

Eye contact: If in eyes, hold eyelids apart and flush the eyes continuously

with running water. Continue flushing until advised to stop by the Poisons

Information Centre or a Doctor; or for at least 15 minutes and transport to

Doctor or Hospital.

Ingestion: Immediately rinse mouth with water. If swallowed, do not induce

vomiting. Give a glass of water to drink. Never give anything by the mouth to

an unconscious patient. If vomiting occurs give further water. Get to a doctor

or hospital quickly.

Notes to physician: Treat symptomatically.

5. Fire-Fighting Measures

Specific hazards: Non-combustible material.

Fire fighting further advice: Not combustible, however following evaporation

of aqueous component residual material can burn if ignited. On burning may

emit toxic fumes. Fire fighters to wear self-contained breathing apparatus

and suitable protective clothing if risk of exposure to vapour or products of

combustion.

Hazchem Code: Not applicable.

Suitable extinguishing media: Not combustible, however, if material is

involved in a fire use water fog (or if unavailable fine water spray), foam, dry

agent (carbon dioxide, dry chemical powder).

6. Accidental Release Measures

Small spills: Wear protective equipment to prevent skin and eye

contamination. Collect and seal in properly labeled containers or drums for

disposal.

Large spills: Slippery when spilt. Avoid accidents, clean up immediately.

Wear protective equipment to prevent skin and eye contamination and the

inhalation of vapours. Work up wind or increase ventilation. Contain –

prevent run off into drains and waterways. Use absorbent (soil, sand or other

inert material). Collect and seal in properly labeled containers or drums for

disposal. If contamination of crops or waterways has occurred advise emergency services or State Department of Agriculture.

Dangerous Goods – Initial Emergency Response Guide No: Not applicable.

7. Handling And Storage

Handling: Avoid skin and eye contact and inhalation of vapour, mist or

aerosols.

Storage: Store in a cool, dry, well ventilated place and out of direct sunlight.

Store away from foodstuffs. Keep containers closed when not in use - check

regularly for leaks.

This material is a Scheduled Poison S5 and must be stored, maintained and

used in accordance with the relevant regulations.

8. Exposure Controls/Personal Protection

National occupational exposure limits: No value assigned for this specific

material. Stel (Short Term Exposure Limit) - the average airborne

concentration over a 15 minute period which should not be exceeded at any

time during a normal eight-hour workday.

Personal protection equipment: overalls, safety shoes, chemical googles,

gloves.

11. Toxicological Information

Acute Effects

Inhalation: Material may be irritant to mucous membranes and respiratory

tract.

Skin contact: A skin sensitiser. Repeated or prolonged skin contact may

lead to allergic contact dermatitis. Eye contact: An eye irritant.

Ingestion: Swallowing can result in nausea, vomiting and abdominal pain.

Acute Toxicity: Ametryn is slightly toxic to humans. Symptoms of acute

exposure to high doses include nausea, vomiting, diarrhea, muscle

weakness, and salivation . Ametryn is moderately irritating to the eyes, skin,

and respiratory tract. The LD50 is the dose of ametryn which is lethal to half

of the test animals that ingest it. The oral LD50 of ametryn is 508 mg/kg for

rats and 945 mg/kg for mice. The LC50 for rats that inhale ametryn for four

hours is greater than 2.2 mg/l of air. The dermal LD50 is greater than 3,100

mg/kg for rats and 8,160 mg/kg for rabbits. Acute eye exposure in rabbits

causes a temporary irritation .

Chronic Toxicity: No information is currently available

Reproductive Effects: No information is currently available.

Teratogenic Effects: No information is currently available.

Mutagenic Effects: Studies have shown that ametryn is not mutagenic.

Carcinogenic Effects: There is not adequate data to determine if ametryn

can increase the risk of cancer in humans.

Organ Toxicity: Animal studies indicate that consuming large amounts of

ametryn over a long period of time results in liver damage.

12. Ecological And Ecotoxicological Information

Effects on Birds: Ametryn is only slightly toxic to birds. The dietary LC50 (8

day) is 30,000 mg/kg for bobwhite quail and 23,000 mg/kg for mallard

ducks.

Effects on Aquatic Organisms: Ametryn is moderately toxic to fish. The

LC50 for rainbow trout exposed for 96 hours is 8.8 mg/l. The LC50 for

bluegill is 4.1 mg/l and for goldfish it is 14.1 mg/l . Ametryn is highly toxic to

crustaceans and moderately to highly toxic to mollusks.

Effects on Other Animals (Nontarget species): Ametryn is only slightly toxic

to bees.

13. Disposal Considerations

Refer to State/Territory Land Waste Management Authority. Triple or

preferably pressure rinse containers before disposal. Add rinsings to 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 bury empty containers in a

local authority landfill. If no landfill is available, bury the containers below

500 mm 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.
