3. HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW:
DANGER! Corrosive to eyes. Causes Irreversible Eye Damage. May be fatal
if ingested. Harmful if absorbed through the skin. Causes skin irritation.
Keep out of reach of children! Do not contaminate food or feed products. Do
not breathe mists.
Toxic to fish, birds and other wildlife. Do not contaminate bodies of water.
POTENTIAL HEALTH EFFECTS
ROUTE(S) OF ENTRY: Poisonous if swallowed, inhaled or absorbed through skin. Contact
with the eyes may cause irreversible eye damage.
SIGNS OF ACUTE OVEREXPOSURE: Symptoms may include, but are not limited to, skin
irritation, blurred vision, and nausea.
SIGNS OF CHRONIC OVEREXPOSURE: There are no known chronic effects associated with
this product.
OTHER POTENTIAL HEALTH EFFECTS: Laboratory studies have shown no carcinogenic
effects in laboratory animals. IARC lists Dichloroethane (Ethylene dichloride) as Group
2B (possibly carcinogenic to humans) and NTP lists Ethylene dichloride as reasonably
anticipated to be a human carcinogen.
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE: Preexisting skin or respiratory
disorders may be aggravated by exposure to components of this product. Avoid skin
contact.
CARE SHOULD BE TAKEN WHEN HANDLING DIFENZOQUAT METHYL SULFATE
AND ITS FORMULATIONS.
4. FIRST AID MEASURES
EXPOSURE TO AVENGE庐 200 C WILD OAT HERBICIDE (DIFENZOQUAT METHYL
SULFATE) CAN CAUSE PERMANENT EYE DAMAGE. MAKE SURE TREATING
PERSONNEL WEAR PROTECTIVE EYEWEAR DURING INITIAL TREATMENT OF
THE EXPOSED INDIVIDUAL.
AMVAC CHEMICAL CORPORATION Page 3 of 8
AVENGE庐 200 C Wild Oat Herbicide AMVAC MSDS No. 345_1
4. FIRST AID MEASURES
EYES: Immediately flush the eyes with copious amounts of clear, cool running water for a
minimum of 15 minutes. Hold the eyelids apart during the flushing to ensure rinsing of
the entire surface of the eyes and lids with water. Contact a physician immediately. If
there will be a delay in getting medical attention, rinse the eyes for at least another 15
minutes.
INHALATION: Remove victim to fresh air if symptoms are observed. If breathing has ceased,
clear the victim's airway and start mouth-to-mouth artificial respiration. If breathing is
difficult, give oxygen. Contact a physician immediately. Be sure the contact areas are
clean to prevent contamination of the rescuer.
INGESTION: Contact a physician or poison control center immediately. Do not induce vomiting.
Immediately dilute the swallowed product by giving large quantities of milk, egg white,
gelatin solution, or, if none of the others is available, water (at least 1 to 2 large glasses).
SKIN: Wash affected areas thoroughly with soap and water. Remove contaminated clothing. Do
not attempt to neutralize with chemical agents. Wash clothing before reuse. If skin
irritation or overexposure symptoms develop, contact a physician immediately.
NOTES TO PHYSICIANS: Probable mucosal damage from swallowing product may
contraindicate the use of gastric lavage.
There is no specific antidote for exposure to this product. There is some evidence from
animal studies that physostigmine sulfate, used in conjunction with norepinephrine, by
injection, may be beneficial in the treatment of acute intoxication by AVENGE庐
following accidental ingestion. Treatment of overexposure should be directed at the
control of symptoms and the clinical condition.
5. FIRE FIGHTING MEASURES
FLAMMABLE PROPERTIES
Flash Point: ~ 217/F (Setaflash Closed-Cup Method)
Autoignition Temperature: Not available

AVENGE庐 200 C Wild Oat Herbicide AMVAC MSDS No. 345_1
5. FIRE FIGHTING MEASURES, cont鈥檇
FIRE FIGHTING INSTRUCTIONS: Evacuate nonessential personnel to a safe area upwind of
the fire. Wear self-contained breathing apparatus. Wear full protective equipment to
prevent skin contact. Runoff from fire control may be a pollution hazard. Wash all
equipment thoroughly with detergent and water before reuse.
6. ACCIDENTAL RELEASE MEASURES
GENERAL: Evacuate personnel and thoroughly ventilate the area. Use adequate ventilation and
appropriate personal protective equipment (PPE, Section 8). Keep bystanders upwind
and away from the spill.
SMALL SPILL: Cover the spill with absorbent material. Shovel the mixture into a sealable
container for disposal as a hazardous waste. If spilled on the ground, the affected area
should be removed and placed into an appropriate container for disposal. Close the drum
and dispose of properly, according to hazardous waste disposal procedures for your
locality.
LARGE SPILL: Dike the spill to prevent contamination of local water sources. Siphon the liquid
into a closed container. Clean up the area as for a small spill.
7. HANDLING AND STORAGE
HANDLING: Avoid exposure to mists and vapors by wearing appropriate personal protective
equipment (PPE, section 8) and adequate ventilation. Always wash hands, face, and arms
with soap and water before smoking, eating, drinking, or going to the toilet.
STORAGE: Store in the original container in a secure, temperate, dry place. Keep away from
heat and open flame. Do not contaminate water, food, or feed. Do not contaminate bodies
of water.
8. EXPOSURE CONTROLS/PERSONAL PROTECTION
ENGINEERING CONTROLS: Ventilation should be sufficient to keep exposures to vapors
below the TLV for the hazardous ingredients of this product (see Section 2). Use of
mechanical or local exhaust systems is recommended.
RESPIRATORY PROTECTION: When respiratory protection is required, or concentrations
may exceed the TLV or PEL, use a NIOSH/MSHA approved air-purifying respirator
equipped with organic vapor cartridges or canisters. It is recommended that the canisters
be changed whenever breakthrough occurs or eight (8) hours of use has occurred,
whichever comes first. For emergency and other conditions where the exposure limit may
be greatly exceeded, use an approved positive-pressure, self-contained breathing
apparatus or positive-pressure airline with auxiliary self-contained air supply.

AVENGE庐 200 C Wild Oat Herbicide AMVAC MSDS No. 345_1
8. EXPOSURE CONTROLS/PERSONAL PROTECTION, cont鈥檇
SKIN PROTECTION: Prevent skin contact. Chemical resistant gloves(preferably nitrile),
coveralls or long-sleeved shirt and pants, and chemical resistant shoes or boots, are
necessary to prevent skin contamination. Remove contaminated clothing as soon as
possible. Wash dirty or contaminated clothing separately from other clothes. Wear clean
clothes daily. Wash well with soap and water after handling this product. See the label
for more specific instructions.
EYE PROTECTION: Safety glasses with sideshields must be worn whenever working with this
product. In addition, goggles or a faceshield are required if there is a chance of splashing
or mist formation.
OTHER PROTECTION: There should be an eyewash station and a safety shower in the work
area.
