7. HANDLING AND STORAGE
Handling:
Avoid inhalation of vapors or spray mist, and contact with skin, eyes and clothing. Wash hands before
eating, drinking, chewing gum, using tobacco or using the toilet. Remove clothing immediately, if
pesticide gets inside. Then wash thoroughly and put on clean clothing. Remove Personal Protection
Equipment immediately after handling this product. Wash the outside of gloves before removing. As soon
as possible, wash thoroughly and change into clean clothing.
Storage:
Always use original container to store pesticides in a secured warehouse or storage building. Containers
should be opened in well-ventilated areas. Keep container tightly sealed when not in use. Do not stack
cardboard cases more than two pallets high. Do not store near open containers of fertilizer, seed or other
pesticides. Do not contaminate water, food, or feed by storage or disposal.
8. EXPOSURE CONTROLS / PERSONAL PROTECTION
Engineering Controls:
If container is over one gallon and less than five gallons, then persons engaged in open pouring of this
product must also wear coveralls or a chemical-resistant apron. If this container is five gallons or more in
capacity, do not open pour product from this container. A mechanical system (such as a probe and pump
or spigot) must be used for transferring the contents of this container. If the contents of a non-refillable
pesticide containers are emptied, the probe must be rinsed before removal.
When handlers use closed systems, enclosed cabs, or aircraft in a manner that meets the requirements
listed in the Worker Protection Standard (WPS) for agricultural pesticides [40 CFR 170.240(d)(4-6)], then
handler PPE requirements may be reduced or modified as specified in the WPS.
Personal Protective Equipment:
Eye/Face Protection: To avoid contact with eyes, wear face shield, goggles or safety glasses with front,
brow and temple protection. An emergency eyewash should be readily accessible to the work area.
Skin Protection: To avoid contact with skin, wear long pants, long-sleeved shirt, socks, shoes and
chemical-resistant gloves. An emergency shower should be readily accessible to the work area.
Respiratory Protection: Not normally required. If vapors or mists exceed acceptable levels, wear
NIOSH approved air-purifying respirator with cartridges/canisters approved for use against pesticides.
General Hygiene Considerations: Personal hygiene is an important work practice exposure control
measure and the following general measures should be taken when working with or handling this
material: 1) Do not store, use and/or consume foods, beverages, tobacco products, or cosmetics in areas
where this material is stored. 2) Wash hands and face carefully before eating, drinking, using tobacco,
applying cosmetics or using the toilet.

11. TOXICOLOGICAL INFORMATION
Toxicological Data:
Data from laboratory studies conducted on a similar, but not identical, formulation:
Oral: Rat LD50: 1,161 mg/kg; FIFRA Category III
Dermal: Rabbit LD50: >2,000 mg/kg; FIFRA Category III
Inhalation: Rat 4-hr LC50: >5 mg/L; FIFRA Category IV
Eye Irritation: Minimally irritating (Rabbit).
Skin Irritation: Minimally irritating (Rabbit).
Subchronic (Target Organ) Effects: Repeated overexposure to phenoxy herbicides may cause effects
to liver, kidneys, blood chemistry, and gross motor function. Rare cases of peripheral nerve damage have
been reported, but extensive animal studies have failed to substantiate these observations, even at high
doses for prolonged periods.
Carcinogenicity / Chronic Health Effects: The International Agency for Research on Cancer (IARC)
lists exposure to chlorophenoxy herbicides as a class 2B carcinogen, the category for limited evidence for
carcinogenicity in humans. However, more current 2,4-D lifetime feeding studies in rats and mice did not
show carcinogenic potential. The U.S. EPA has given 2,4-D a Class D classification (not classifiable as
to human carcinogenicity).
Reproductive Toxicity: No impairment of reproductive function attributable to 2,4-D have been noted in
laboratory animal studies.
Developmental Toxicity: Studies in laboratory animals with 2,4-D have shown decreased fetal body
weights and delayed development in the offspring at doses toxic to mother animals
Genotoxicity: There have been some positive and some negative studies, but the weight of evidence is
that 2,4-D is not mutagenic.
Assessment Carcinogenicity:
This product contains substances that are considered to be probable or suspected human carcinogens
as follows:
Regulatory Agency Listing As Carcinogen
Component ACGIH IARC NTP OSHA
Chlorophenoxy Herbicides No 2B No No

12. ECOLOGICAL INFORMATION
This product is toxic to aquatic invertebrates. Drift or runoff may adversely affect aquatic invertebrates
and non-target plants. For terrestrial uses, do not apply directly to water, or to areas where surface water
is present or to intertidal areas below the mean high water mark. Vapors from this product may injure
susceptible plants in the immediate vicinity. Use care to avoid spray contact or drift of 2,4-D susceptible
plants such as cotton, flowers, fruit trees, grapes, okra, ornamentals and tomatoes. Do not permit spray
mist containing this product to drift onto them. Do not spray when the wind is blowing towards susceptible
crops or ornamental plants. Use coarse sprays and/or low spray pressure
Most cases of groundwater contamination involving phenoxy herbicides such as 2,4-D have been
associated with mixing/loading and disposal sites. Caution should be exercised when handling 2,4-D
pesticides at such sites to prevent contamination of groundwater supplies. Use of closed systems for
mixing or transferring this pesticide will reduce the probability of spills. Placement of the mixing/loading
equipment on an impervious pad to contain spills will help prevent groundwater contamination.
Ecotoxicity:
Data on 2,4-D EHE
96-hour LC50 Bluegill: >5 mg/l
96-hour LC50 Rainbow Trout: 7.2 mg/l
48 hour EC50 Daphnia: >5 mg/l
Bobwhite Quail Oral LD50: >5620 mg/kg
Mallard Duck 8 day Dietary LC50: >5620 ppm
Environmental Fate:
In laboratory and field studies, 2,4-D 2-ethylhexyl ester rapidly de-esterfied to parent acid in the
environment. The typical half-life of the resultant 2,4-D acid ranged from a few days to a few weeks.
13. DISPOSAL CONSIDERATIONS
Do not contaminate water, food or feed by storage or disposal.
Waste Disposal Method:
Pesticide wastes are toxic. If container is damaged or if pesticide has leaked, contain all spillage. Absorb
and clean up all spilled material with granules or sand. Place in a closed labeled container for proper
disposal. Improper disposal of excess pesticide, spray mixtures, or rinsate is a violation of Federal law
and may contaminate groundwater. If these wastes cannot be disposed of by use according to label
instructions, contact your State Pesticide or Environmental Control Agency, or the Hazardous Waste
representative at the nearest EPA Regional Office for guidance.
Container Handling and Disposal:
Triple rinse (or equivalent). 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. Plastic containers are
also disposable by incineration, or if allowed by State and local authorities, by burning. If burned, stay out
of smoke.
