HEALTH HAZARD DATA
Acute Swallowed: The oral LD
(rat and mouse) is above 5000 mg/kg (low toxicity).
Eye: Eye contact withmetsulfuron methyl may cause eye irritation with tearing,
pain or blurred vision.
Skin: The acute dermal LD
(rabbit) is above 2000 mg/kg (low toxicity). Repeated
dermal contact withmetsulfuron methyl may cause skin irritation with itching,
burning, redness, swelling or rash.
Inhaled: The4 hour inhalation LC
(rat) is greater than 5.3 mg/L (low toxicity). May
irritate the throat.
Chronic Possible chronic health effects from exposure to DowAgroSciencesMetsulfuron are based on
studies on the active ingredient. Metsulfuron does not have carcinogenic, developmental or
reproductive effects. There is a report indicating thatmetsulfuron methyl produced genetic
damage in amammalian cell culture test, however, other tests withmetsulfuron methyl in
bacterial and mammalian cell cultures and in animals did not produce genetic damage. The
weight of evidence suggests thatmetsulfuron methyl does not cause genetic damage. Long
term administration caused body weight loss. The ingredients are not listed as carcinogenic in
NOHSC’s document “Exposure Standards for Atmospheric Contaminants in the Occupational
PERSONAL PROTECTION AND SAFETY DIRECTIONS
May irritate the eyes and skin. Avoid contact with eyes and skin. DO NOT inhale dust or spray mist. After use and
before eating, drinking orsmoking, wash hands, arms and face thoroughly with soap and water.
General: Consult The National Poisons Information Centre (Ph: 13 11 26) or a Doctor in every case of
suspected chemical poisoning. Never give fluids or induce vomiting if a patient is unconscious or
convulsing regardless of cause of injury. If breathing difficulties occur seek medical attention
Swallowed: If swallowed, contact the Poisons Information Centre or a doctor immediately.
Skin: If on skin,remove contaminated clothing and wash skin thoroughly with soap and water.
Eyes: If in eyes, hold eyes open and flood with water for at least 15 minutes and see a doctor.
Inhalation: If affected by dust, remove from contaminated area to fresh air. If not breathing, give artificial
respiration. If breathing is difficult, give oxygen. Seek medical attention.
PRECAUTIONS FOR USE
A time weighted average (TWA) concentration for an 8 hour day, and 5 day week has not been established by
NOHSC for the formulated product. There is a blanket limit of 10mg/m 3 for dusts or mists when limits have not
otherwise been established.AEL (DuPont) 10 mg/m 3
(8 and 12hr TWA). The ADI (Acceptable Daily Intake) for
metsulfuron methyl is set at 0.01mg/kg/day. The corresponding NOEL (No-observable-effect-level) is set at
1mg/kg/day. Values taken from Australian ADI List,January, 2001.
In industrial situations, concentrated values below the TWA value should be maintained. Values may be reduced
by process modification, use of local exhaust ventilation, capturing substances at the source, or other methods. If
you believe airborne concentrations of mists, dusts or vapours are high, you are advised to modify the process or
environment to reduce the problem.
