Section 3 - Composition/Information on Ingredients
TWA (mg/m3) STEL (mg/m3)
Ingredients CAS No Conc,%
Metsulfuron methyl 74223-64-6 60 not set not set
Other non hazardous ingredients secret to 100 not set not set
This is a commercial product whose exact ratio of components may vary slightly. Minor quantities of other non
hazardous ingredients are also possible.
The TWA exposure value is the average airborne concentration of a particular substance when calculated over a normal 8 hour working day for a 5
day working week. The STEL (Short Term Exposure Limit) is an exposure value that should not be exceeded for more than 15 minutes and should
not be repeated for more than 4 times per day. There should be at least 60 minutes between successive exposures at the STEL. The term "peak "is
used when the TWA limit, because of the rapid action of the substance, should never be exceeded, even briefly.
Section 4 - First Aid Measures
General Information:
You should call The Poisons Information Centre if you feel that you may have been poisoned, burned or irritated by
this product. The number is 13 1126 from anywhere in Australia (0800 764 766 in New Zealand) and is available at all
times. Have this MSDS with you when you call.
Inhalation: First aid is not generally required. If in doubt, contact a Poisons Information Centre or a doctor.
Skin Contact: Gently brush away excess solids. Irritation is unlikely. However, if irritation does occur, flush with
lukewarm, gently flowing water for 5 minutes or until chemical is removed.
Eye Contact: Quickly and gently brush particles from eyes. No effects expected. If irritation does occur, flush
contaminated eye(s) with lukewarm, gently flowing water for 5 minutes or until the product is removed. Obtain medical
advice if irritation becomes painful or lasts more than a few minutes.
Ingestion: If product is swallowed or gets in mouth, wash mouth with water and give some water to drink. If
symptoms develop, or if in doubt contact a Poisons Information Centre or a doctor.
Section 5 - Fire Fighting Measures
Fire and Explosion Hazards: There is no risk of an explosion from this product under normal circumstances if it is
involved in a fire.
Fire decomposition products from this product may be toxic if inhaled. Take appropriate protective measures.
Extinguishing Media: Preferred extinguishing media are carbon dioxide, dry chemical, foam, water fog.
Fire Fighting: If a significant quantity of this product is involved in a fire, call the fire brigade.
Flash point: Not flammable.
Upper Flammability Limit: No data.
Lower Flammability Limit: No data.
Autoignition temperature: No data.

Section 6 - Accidental Release Measures
Accidental release: Minor spills do not normally need any special cleanup measures. In the event of a major spill,
prevent spillage from entering drains or water courses. As a minimum, wear overalls, goggles and gloves. Suitable
materials for protective clothing include rubber, PVC. Eye/face protective equipment should comprise as a minimum,
protective glasses and, preferably, goggles. If there is a significant chance that dusts are likely to build up in cleanup
area, we recommend that you use a suitable Dust Mask.
Stop leak if safe to do so, and contain spill. Sweep up and shovel or collect recoverable product into labelled
containers for recycling or salvage, and dispose of promptly. Consider vacuuming if appropriate. Recycle containers
wherever possible after careful cleaning. Refer to product label for specific instructions. After spills, wash area
preventing runoff from entering drains. If a significant quantity of material enters drains, advise emergency services.
Full details regarding disposal of used containers, spillage and unused material may be found on the label. If there is
any conflict between this MSDS and the label, instructions on the label prevail. Ensure legality of disposal by
consulting regulations prior to disposal. Thoroughly launder protective clothing before storage or re-use. Advise
laundry of nature of contamination when sending contaminated clothing to laundry.
Section 7 - Handling and Storage
Handling: Keep exposure to this product to a minimum, and minimise the quantities kept in work areas. Check
Section 8 of this MSDS for details of personal protective measures, and make sure that those measures are followed.

weakness, dizziness, headache, nausea, vomiting, coma, convulsions, and death. Death results from respiratory
arrest. Hydrogen cyanide gas acts very rapidly; symptoms and death can both occur quickly.
Polymerisation: This product will not undergo polymerisation reactions.
Section 11 - Toxicological Information
Toxicity: Acute Toxicity: Metsulfuron methyl has very low toxicity in mammals. LD50 is > 5,000 mg/kg in rats. It has
low dermal toxicity in tests with rabbits, with an LD50 > 2,000 mg/kg, and low inhalation toxicity in rats, with a median
lethal concentration in air of greater than 5 mg/L air. Moderate but reversible eye irritation has been seen in rabbits,
and mild skin irritation has been observed in guinea pigs. No skin sensitization has been observed in guinea pigs.
Chronic Toxicity: A 2-year feeding study in rats resulted in a NOEL of 25.0 mg/kg/day (or 500 ppm in feed), based
on decreased body weights seen at 250 mg/kg/day (5,000 ppm) which was the highest dose tested. EPA has based
its reference dose (0.25 mg/kg/day) on this study.
Reproductive Effects: Multigenerational studies in rats did not result in any reproductive effects at the highest doses
tested of 250 mg/kg/day.
Teratogenic Effects: Metsulfuron-methyl did not cause developmental abnormalities to offspring of rats and rabbits
fed 1000 mg/kg/day and 700 mg/kg/day respectively during gestation. These doses represent the highest dose tested
for each experiment.
Mutagenic Effects: The weight of evidence presented by a battery of tests to measure mutagenicity and other
adverse effects on DNA indicates that Metsulfuron-methyl is neither mutagenic nor genotoxic.
Carcinogenic Effects: Negative for rats and mice in laboratory tests, but studies may not have been at maximum
tolerated dose.
Organ Toxicity: Metsulfuron-methyl is a moderate eye irritant.
Fate in Humans and Other Animals: The chemical is broken down quickly and eliminated from the body. In tests
with radio labelled Metsulfuron-methyl in rats, the excretion half-lives ranged from 9 to 16 hours and 23 to 29 hours for
rats administered low and high doses, respectively. It did not bioaccumulate in fish.
Section 12 - Ecological Information
Breakdown of Chemical in Soil and Groundwater: The breakdown of Metsulfuron-methyl in soils is largely dependant
on soil temperature, moisture content, and pH. The chemical will degrade faster under acidic conditions, and in soils
with higher moisture content and higher temperature. The chemical has a higher mobility potential in alkaline soils
than in acidic soils, as it is more soluble under alkaline conditions. Metsulfuron-methyl is stable to photolysis, but will
break down in ultraviolet light. Half-life estimates for Metsulfuron-methyl in soil are wide ranging from 14 - 180 days,
with an overall average of reported values of 30 days. Reported half-life values (in days) for soil include: clay - 178 ;
sandy loam - 102 ; clay loam - 70 , 14-28 , 14-105 ; silty loam - 120-180.
Breakdown of Chemical in Surface Water: The dissipation time for Metsulfuron-methyl was investigated in a mixed
wood/boreal forest lake. The DT50 or length of time required for half of the material to dissipate in water was >84 days
when high concentrations of Metsulfuron-methyl were applied, and 29.1 days at concentrations that might be
expected if the chemical is applied for forestry uses. It is stable to hydrolysis at neutral and alkaline pHs, and has a
half-life of 3 weeks at pH 5.0, 25掳C and >30 days at 15掳C.
Breakdown of Chemical in Vegetation: Metsulfuron-methyl is rapidly taken up by plants at the roots and on foliage.
The chemical is translocated throughout the plant, but is not persistent. It is broken down to non-herbicidal products in
tolerant plants.
