HEALTH HAZARD DATA

HEALTH EFFECTS

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.

FIRST AID

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

immediately.

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

EXPOSURE STANDARDS

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.

ENGINEERING CONTROLS

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.
