POTENTIAL HEALTH EFFECTS
EYES: The undiluted product is moderately irritating to the eyes. Eye contact may include discomfort, tearing, swelling, redness, and blurred vision.
SKIN: The undiluted product is considered a slight skin irritant. Skin irritation may include discoloration, itching and swelling. This substance is slightly toxic to internal organs if absorbed through the skin. The degree of injury will depend on the amount absorbed.
INGESTION: This substance is slightly toxic to internal organs if swallowed. The degree of injury will depend on the amount absorbed from the gut.
INHALATION: The systemic toxicity of this substance has not been determined. However, results of a rat 4 hour aerosol inhalation study on a similar formulation, indicated a slight degree of toxicity.
Chronic Health Effects: From MSDS
NEUROTOXICITY: Numerous neurotoxicity studies involving several species, using high dose and repeated administration of 2,4-D, failed to demonstrate any clinically or histological evidence that the chemical is a neurotoxin.
REPRODUCTIVE TOXIN: 2,4-D has not demonstrated adverse reproductive effects or to have been associated with any teratological or birth defects.
MUTAGENICITY: 2,4-D is not considered a mutagen.
Carcinogenicity: From MSDS
CARCINOGENICITY COMMENTS:
Based on the results of animal toxicology studies, epidemiological investigations and findings from scientific review groups, 2,4-D is not considered to be a carcinogen. The EPA has classed 2,4-D in carcinogenic category ***D*** meaning the weight of the scientific evidence does not demonstrate a cause and effect relationship between 2,4-D and cancer.
First Aid: From MSDS
EYES: Hold eye open and rinse slowly and gently with water for 15 to 20 minutes. Remove contact lenses, if present, after the first 5 minutes, then continue rinsing eyes. Call a poison control center or doctor for treatment advice.
SKIN: If on skin or clothing, take off contaminated clothing. Rinse skin immediately with plenty of water for 15 to 20 minutes. Call a poison control center or doctor for treatment advice.
INGESTION: If swallowed, call a poison control center or doctor immediately for treatment advice. Have person sip glass of water if able to swallow. Do not induce vomiting unless told to by a poison control center or doctor. Never give anything by mouth to an unconscious person.
INHALATION: Move person to fresh air. If person is not breathing, call 911 or an ambulance, then give artificial respiration, preferably by mouth-to-mouth, if possible. Call a poison control center or doctor for further treatment advice.

Handling/Disposal
Handling: From MSDS
GENERAL PROCEDURES: Keep pesticide in original container. Do not put concentrate or dilute into food or drink containers. Store in a secure, preferably locked, storage area. Protect container from freezing.

ECOTOXICOLOGICAL INFORMATION: This product is toxic to aquatic invertebrates. Drift or runoff may adversely affect aquatic invertebrates and non-target plants. Do not apply directly to water, or 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 when weather conditions favor drift from target area. When cleaning equipment, do not pour the washwater on the ground, spray or drain over a large area away from wells and other sources. Most cases of groundwater contamination involving phenoxy herbicides such as 2,4-D and MCPP have been associated with mixing/loading and disposal sites. Caution should be exercised when handling 2,4-D and MCPP 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.
Disposal: From MSDS
If necessary to dispose of partially filled product container, securely wrap it in several layers of newspaper and discard in trash.
EMPTY CONTAINER: Do not reuse container. Rinse thoroughly before discarding in trash.
