Yes Yes No
PRIMARY ROUTE OF ENTRY: Dermal/ Eye: Oral: Inhalation:
Nonspecific: muscle weakness, lethargy, loss of appetite, abdominal
SYMPTOMS OF OVEREXPOSURE:
pains, headache, or shortness of breath.
ACUTE HEALTH EFFECTS
Inhalation: Avoid inhaling vapors or mist. May irritate the respiratory tract or cause
dizziness.
Eyes: Direct and prolonged eye exposure to the concentrated product may
cause corneal opacity, irreversible eye damage.
This product is considered a minimal skin irritant and is not a dermal
Skin:
sensitizer. Harmful if absorbed through skin. May cause similar
symptoms to ingestion.
May cause muscle weakness, nausea, diarrhea, and abdominal pain. Fall

in blood pressure or myotonia (prolonged muscular spasm) may occur
under extreme exposure conditions. Can be fatal.

MEDICAL CONDITIONS POSSIBLY
AGGRAVATED BY EXPOSURE: Skin exposure may aggravate existing skin conditions. Exposure to mist
may aggravate existing respiratory conditions.
Chronic overexposure to dicamba may cause liver changes or a decrease
CHRONIC HEALTH EFFECTS:
in body weight. The EPA's Science Advisory Panel has given dicamba a
Agency Listing Carcinogen class D classification (not classifiable as to human carcinogenicity).
NTP IARC OSHA Animal tests with Dicamba have not demonstrated carcinogenic,
No
No No teratogenic, or reproductive effects with the exception of slightly reduced
fetal body weights and post implantation losses reported at the Maximum
Tolerated Dose level. The majority of evidence suggests that dicamba is
not a mutagen. Repeated or prolonged overexposure to phenoxy
herbicides may cause liver, kidney, gastrointestinal or muscular system
effects. The available evidence on MCPA indicates that it is not a
carcinogen or mutagen. No conclusions can be drawn about the
teratogenic risk of MCPA. Other chronic effects of MCPP have not been
determined.
3. FIRST AID MEASURES
Hold eyelids open and flush entire eye with a steady, gentle stream of
EYE CONTACT:
water for 15 minutes. Get medical attention at once.
Remove victim to fresh air. If not breathing, give artificial respiration
INHALATION:
preferably mouth to mouth. Get medical attention.
Call a physician or Poison Control Center. Drink promptly a large
INGESTION:
quantity of milk, egg whites or gelatin solution, or, if these are not
available, drink large quantities of water. Avoid alcohol. Do not induce
vomiting or give anything by mouth to an unconscious person.
If contacted with the concentrate, wash with plenty of soap and water.
SKIN CONTACT:
Get medical attention. If contact is made after this product has been
diluted, wash with plenty of soap and water. Rinse thoroughly.
Probable mucosal damage may contraindicate gastric lavage. If large
NOTE TO PHYSICIAN:
amounts of the product were ingested, the stomach should be emptied by
gastric intubation.
4. FIRE FIGHTING MEASURES
N/A
FLASH POINT (F):
None-aqueous solution
FLASH POINT METHOD USED:
EXTINGUISHING MEDIA: Use C02 or dry chemical for small fires and foam, water fog, or water
stream for large fires. Use water spray to cool closed containers.
May include, but are not limited to: hydrogen chloride and nitrogen
COMBUSTION PRODUCTS:
oxides.
May produce toxic and noxious fumes under extreme fire conditions. Use
SPECIAL FIRE FIGHTING PROCEDURES:
positive pressure self-contained breathing apparatus and acid resistant
protective clothing. Any water used to extinguish the fire should be
contained by diking to prevent contamination of the public water system.
UNUSUAL FIRE & EXPLOSION HAZARDS: Drums of product will burst from steam pressure under prolonged fire
conditions.
See Section 13, REGULATORY INFORMATION, for NFPA ratings.

5. ACCIDENTAL RELEASE MEASURES
STEPS TO BE TAKEN IN CASE MATERIAL IS SPILLED OR RELEASED:
When cleaning large spills, wear the suggested safety equipment (see section 7). Surround with impervious material such as dirt or clay
to prevent run-off. Absorb product with an inert absorbent such as granules. Contain all affected material in a closed, labeled container
for proper disposal. Treat contaminated area with detergent and water.
6. HANDLING AND STORAGE
PRECAUTIONS TO BE TAKEN IN HANDLING AND STORAGE:
Always use original container to store pesticides in a secured warehouse or storage building. Do not store near seeds, fertilizers,
insecticides, or fungicides. Store at temperatures above 32 F. If allowed to freeze, remix before using. Freezing does not alter this
product. 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 contaminate water, food, or feed by storage or disposal.
WORK HYGIENIC PRACTICE:
Wash thoroughly with soap and water after handling. Remove contaminated clothing and wash before reuse.
7. EXPOSURE CONTROL/PERSONAL PROTECTION
Respiratory protection is not normally required. Use a NIOSH/MSHA
RESPIRATORY PROTECTION:
approved respirator when directly exposed to mist.
Open ventilation. Reduce all mist with local exhaust.
VENTILATION:
PROTECTIVE GLOVES: Rubber or chemical-resistant gloves
Wear splash goggles or face shield when mixing or loading.
EYE PROTECTION:
Long sleeved shirt, long pants, socks and shoes are recommended.
