SECTION 3. HAZARDS IDENTIFICATION
NOTE: Please refer to Section 11 for detailed toxicological information.
Emergency Overview Warning! May be fatal if swallowed. May be harmful if inhaled. May be harmful if
absorbed through skin. May cause eye irritation. May cause mild skin
sensitization.
Physical State liquid
Odor sulfur-like odor
Appearance cream colored
Immediate Effects
Eye Causes redness, irritation, tearing.
Skin Harmful if absorbed through skin. May produce symptoms similar to those from
ingestion.
Ingestion May be fatal if swallowed. This product causes reversible cholinesterase
inhibition. Repeated overexposure may cause more severe cholinesterase
inhibition with more pronounced signs and symptoms. May lead to rapid onset of
nausea, vomiting, diarrhea, pinpoint pupils, blurred vision, profuse sweating,
temporary paralysis, respiratory depression, and convulsions.
Inhalation Highly toxic if inhaled. May produce symptoms similar to those from ingestion.
Chronic or Delayed This product does not contain any ingredients designated by IARC, NTP, ACGIH
Long-Term or OSHA as probable or suspected human carcinogens.
Medical Conditions Inhalation of product may aggravate existing chronic respiratory problems such
Aggravated by Exposure as asthma, emphysema or bronchitis. Skin contact may aggravate existing skin
disease.
SECTION 4. FIRST AID MEASURES
Eye Hold eyelids open and flush with a steady, gentle stream of water for at least 15
minutes. Seek medical attention.
Skin In case of contact, immediately wash with plenty of soap and water for atleast 15
minutes. Seek medical attention. Remove contaminated clothing and shoes
while washing. Clean contaminated clothing and shoes before re-use or discard
if they cannot be thoroughly cleaned.
Ingestion If victim is conscious and alert, give 2-3 glasses of water to drink and induce
vomiting by touching back of throat with a finger. Do not induce vomiting or give
anything by mouth to an unconscious person. Seek immediate medical attention.
Do not leave victim unattended. Vomiting may occur spontaneously. To prevent

aspiration of swallowed product, lay victim on side with head lower than waist. If
vomiting occurs and the victim is conscious, give water to further dilute the
chemical.
Inhalation Remove victim from immediate source of exposure and assure that the victim is
breathing. If breathing is difficult, administer oxygen, if available. If victim is not
breathing, administer CPR (cardio-pulmonary resuscitation). Seek medical
attention.
Note to Physician All treatment should be based on observed signs and symptoms of distress in
the patient. Consideration should be given to the possibility that overexposure to
materials other than this product may have occurred.
This product contains a methyl carbamate insecticide, which is a chloinesterase
inhibitor. Overexposure to this substance may cause toxic signs and symptoms
due to stimulation of the cholinergic nervous system. These effects of
overexposure are spontaneously and rapidly reversible.
Specific treatment consists of parenteral atropine sulfate. Improve tissue
oxygenation as much as possible before administering atropine to minimize the
risk of ventricular fibrillation. Mild cases may be given 1 to 2 mg intramuscularly
every 10 minutes until full atropinization has been achieved and repeated
thereafter whenever symptoms reappear. Severe cases should be given 2 to 4
mg intravenously every 10 minutes until fully atropinized, then intramuscularly
every 30 to 60 minutes as needed to maintain the effect for at least 12 hours.
Dosages for children should be appropriately reduced. Complete recovery from
overexposure is to be expected within 24 hours.
To aid in confirmation of a diagnosis, urine samples should be obtained within 24
hours of exposure and immediately frozen. Call 1-800-334-7577 before sending
samples. Analysis will be arranged by Bayer.
Persons regularly exposed in manufacturing and handling this product should
have a preexposure and periodic red blood cell cholinesterase level checks.
Narcotics and other sedative should not be used. Further, drugs like 2-PAM
(pyridine-2-aldoxime methiodide) are NOT recommended.

area to prevent runoff and contamination of water sources. Dispose of fire
control water later. Persons who may have been exposed to contaminated
smoke should be immediately examined by a physician and checked for
symptoms of poisoning. The symptoms should not be mistaken for heat
exhaustion or smoke inhalation.
SECTION 6. ACCIDENTAL RELEASE MEASURES
General and Disposal Evacuation Procedures and Safety: Evacuate and isolate spill area.
Cleanup and Disposal of Spill: Recover material, if possible. Pump any free
liquid into an appropriate closed container. Absorb with vermiculite or other inert
absorbent. Shovel up into an appropriate closed container (see Section 7:
Handling and Storage). Decontaminate tools and equipment following cleanup.
Land Spill or Leaks Containment of Spill: Dike spill using absorbent or impervious materials such as
earth, sand or clay. Follow procedure under Cleanup and Disposal of Spill.
Collect and contain contaminated absorbent and dike material for disposal.
Environmental and Regulatory Reporting: Prevent material from entering public
sewer system or any waterway. Spills may be reportable to the National
Response Center (800-424-8802) and to state and/or local agencies. If spilled on
the ground, the affected area should be removed to a depth of one or two inches
and placed in an appropriate container for disposal.
SECTION 7. HANDLING AND STORAGE
Handling Procedures Avoid direct or prolonged contact with skin and eyes. Do not ingest. Do not
breathe vapors and mists.
Storing Procedures Store in original container. Store unused product in a cool, ventilated, dry, locked
area. Keep out of reach of children and domestic animals. Store in an area that
is away from food, feedstuffs, fertilizers and seed, away from the home or home
garden.
Work/Hygienic Personal hygiene is an important work practice exposure control measure and
Procedures the following general measures should be taken when working with or handling
this material:
Do not store, use, and/or consume foods, beverages, tobacco products, or
cosmetics in areas where this material is stored.
Wash hands and face carefully before eating, drinking, using tobacco, applying
cosmetics, or using the toilet.
Wash exposed skin promptly to remove accidental splashes of contact with this
material.

SECTION 8. EXPOSURE CONTROLS/PERSONAL PROTECTION
Engineering Controls Where engineering controls are indicated by use conditions of a potential for
excessive exposure exists, the following traditional exposure control techniques
may be used to effectively minimize employee exposures: local exhaust
ventilation at the point of generation.
Eye/Face Protection Eye and face protection requirements will vary dependent upon work
environment conditions and material handling practices. Appropriate ANSI Z87
approved equipment should be selected for the particular use intended for this
material.
Eye contact should be prevented through use of chemical safety glasses with
side shields or splash proof goggles. An emergency eye wash must be readily
accessible to the work area.
Body Protection Skin contact should be prevented through use of suitable protective clothing,
gloves and footwear, selected with regard of use conditions and exposure
potential. Consideration must be given both to durability as well as permeation
resistance.
Respiratory Protection When respirators are required, select NIOSH/MSHA approved equipment based
on actual or potential airborne concentrations and in accordance with the
appropriate regulatory standards and/or industrial recommendations.
Under normal conditions, in the absence of other airborne contaminants, the
following should provide protection from this material up to the conditions
specified by the appropriate OSHA, WHMIS or ANSI standard(s): Air-purifying
(half-mask/full-face) respirator with cartridge/canister approved for use against
pesticides.
Under conditions immediately dangerous to life or health, or emergency
conditions with unknown concentrations, use a full-face positive pressure air-
supplied respirator equipped with an emergency escape air supply unit or use a
self-contained breathing apparatus unit.
General Protection These recommendations provide general guidance for handling this product.
Because specific work environments and material handling practices vary, safety
procedures should be developed for each intended application. While developing
safe handling procedures, do not overlook the need to clean equipment and
piping systems for maintenance and repairs. Waste resulting from these
