HAZARD IDENTIFICATION
Emergency overview: CAUTION! Causes moderate eye irritation. Avoid contact with eyes,
skin, or clothing. Wear long-sleeved shirt and long pants, socks and shoes and waterproof
gloves.
Potential health effects: Based on animal data, skin contact with tribenuron methyl may
cause skin irritation with discomfort or rash significant skin permeation, and systemic toxicity,
after contact appears unlikely. There are no person of human skin sensitization. Based on
animal data, eye contact with tribenuron methyl may cause eye irritation with discomfort,
tearing, or blurring of vision. Based on animal data, inhalation of tribenuron methyl may
cause irritation of the upper respiratory passages, with coughing and discomfort.
Carcinogenicity information: None of the components present in this material at
concentrations equal to or greater than 0.1 % are listed by IARC, NTP, OSHA or ACGIH as a
carcinogen.

TOXICOLOGICAL INFORMATION
ANIMAL DATA
Inhalation 4 hour LC50: > 6.7 mg/L in rats. (very low toxicity)
Skin absorption LD50: > 2000 mg/kg in rabbits. (very low to moderately toxic)
Oral LD50: > 5000 mg/kg in rats. (very low toxicity)
Tribenuron methyl is an eye irritant, and a skin sensitizer, but is not a skin irritant in
animals.The effects in animals from a single ingestion exposure to tribenuron methyl include
severe weight loss and decreased food consumption. Repeated ingestion doses caused body
weight loss, increased liver and thyroid/parathyroid weights , altered clinical Chemical
parameters, but no significant gross or microscopic treatment related effects were noted.
long-term dosing caused body weight loss, alteration in clinical chemical parameters, and
testicular atrophy (considered to be biologically insignificant). Tribenuron methyl produced
an increased incidence of mammary tumors in female rats at dose levels also producing other
significant effects. developmental effects occurred in the rat, but only at a dose also toxic to
the dam. no reproductive effects were observed in rats. tribenuron methyl did not produce
genetic damage in bacterial or mammalian cell cultures or in animals.

DISPOSAL CONSIDERATIONS
WASTE DISPOSAL: Do not contaminate water, food, or feed by disposal. Waste resulting
from the use of this product may be disposed of on site or at an approved waste disposal
facility. Environmental hazards do not apply directly to water, or to areas where surface water
is present, or to intertidal areas below the mean high water mark. Do not contaminate water
when disposing of equipment washwaters. Do not apply where/when conditions favor runoff.
CONTAINER DISPOSAL: For plastic containers: Triple rinse (or equivalent). Then offer
for recycling or reconditioning, or puncture and dispose of in a sanitary landfill, or
incineration, or, if allowed by state and local authorities, by burning. If burned, stay out of
smoke.
FOR FIBER SACKS: Completely empty fiber sack by shaking and tapping sides and bottom
to loosen clinging particles.Empty residue into manufacturing or application equipment.Then
dispose of sack in a sanitary landfill or by incineration if allowed by state and local authorities.
For fiber drums with liners: completely empty liner by shaking and tapping sides and bottom
to loosen clinging particles. Empty residue into application equipment. Then dispose of liner
in a sanitary landfill or by incineration if allowed by state and local authorities. If drum is
contaminated and cannot be reused, dispose of in the same manner. For bags containing
water-soluble packets: do not reuse the outer box or the resealable plastic bag. when all
water-soluble packets are used, the outer packaging should be clean and may be disposed of
in a sanitary landfill or by incineration, or if allowed by state and local authorities, by open
burning. if burned, stay out of smoke. if the resealable plastic bag contacts the formulated
product in any way, the bag must be triple-rinsed with clean water. Add the rinsate to the
spray tank and dispose of the outer wrap as described above. For metal containers (non
aerosol): triple rinse (or equivalent) the container. then offer for recycling or reconditioning,
or puncture and dispose of in a sanitary landfill, or by other procedures approved by state and
local authorities. For paper and plastic bags: completely empty bag into application
equipment. then dispose of empty bag in a sanitary landfill or by incineration, or, if allowed
by state and local authorities, by burning. if burned, stay out of smoke.
