3. HAZARDS IDENTIFICATION SUMMARY
KEEP OUT OF REACH OF CHILDREN ?WARNING - AVISO ?Si usted no entiende la etiqueta, busque a alguien para que se la explique a usted en
detaile (If you do not understand the label, find someone to explain it to you in detail.) May be fatal if swallowed. Causes substantial but temporary eye

Warning Statements:
NOTE TO PHYSICIAN : This product is an organophosphate (cholinesterase-inhibiting) insecticide. Atropine is antidotal and should be only if symptoms of
cholinesterase inhibition are present. In severe cases Pralidoxime chloride (2-PAM; PROTOPAM) may be given as an adjunct to atropine. Use
according to label directions. Monitor serum and RBC cholinesterase. Morphine, theophylline, aminophylline, phenothiazines, reserpine, furosemide, or
ethacrynic acid are contraindicated in organophosphates poisonings. Administer intravenous fluids cautiously, if needed, to correct dehydration.
Symptoms of cholinesterase inhibition include headache, dizziness, blurred vision, weakness, nausea, cramps, diarrhea, discomfort in the chest,
nervousness, sweating, miosis, tearing, salivation, pulmonary edema, incontrollable twitches, convulsions, coma, and loss of reflexes and sphincter
control.
4. FIRST AID MEASURES
If swallowed: Call a poison control center or doctor immediately for treatment advice. Have person sip a glass of water if able to swallow.
Do not induce vomiting unless told to do so by a poison control center or doctor. Do not give anything by mouth to an
unconscious person.
If in inhaled: 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 treatment advice.
If on skin or clothing: Take off contaminated clothing. Rinse skin immediately with plenty of water for 15-20 minutes. Call a poison control center or
doctor for treatment advice.
If in eyes: Hold eye open and rinse slowly and gently with water for 15-20 minutes. Remove contact lenses, if present, after the first
5 minutes, then continue rinsing eye. Call a poison control center or doctor for treatment advice.
FOR A MEDICAL EMERGENCY INVOLVING THIS PRODUCT CALL: 1-866-303-6950. Have the product label or container with you when calling a poison control
center or doctor, or going for treatment.
5. FIRE FIGHTING MEASURES
>109oF/>42.8oC (PMCC)
FLASH POINT (癋/Test Method):
FLAMMABLE LIMITS (LEL & UEL): None established
EXTINGUISHING MEDIA: Dry chemical, carbon dioxide, foam, water spray or fog.
HAZARDOUS COMBUSTION PRODUCTS: Oxides of sulfur, phosphorus -containing compounds, carbon monoxide and other unknown hazardous
materials may be formed.
SPECIAL FIRE FIGHTING PROCEDURES: Wear self-contained breathing apparatus with full protective clothing. Fight fire from upwind and keep
all non-essential personnel out of area.
UNUSUAL FIRE AND EXPLOSION HAZARDS: If water is used to fight fire and cool the containers, contain run-off by diking to prevent
contamination of water supplies. Containers in fire may burst or explode from excessive heat.
6. ACCIDENTAL RELEASE MEASURES
STEPS TO BE TAKEN IF MATERIAL IS RELEASED OR SPILLED:
For small spills, absorb wi an absorbent material such as pet litter. Sweep up and transfer to containers for possible land application according to label
th
use or for proper disposal. Wash the spill with water containing a strong detergent, absorb with pet litter or other absorbent material, sweep up and
place in a chemical container and handle in an approved manner. Check local, state and federal regulations for proper disposal. Flush the area with
water to remove any residue. For large spills: contain liquid by diking the area, keep product out of water supplies. If possible, use a pump to pick up
liquid, then use absorbent material to absorb any residual liquid. Place both in a chemical container. Flush area with a household bleach and water
mixture (1:1) and then absorb the liquid as described above in small spills.
CAUTION: Keep spills and cleaning runoff out of municipal sewers and open bodies of water.

EPA HANDLER REQUIREM ENTS
Worker Protection Standard ?40 CFR 170
Personal Protective Equipment: Applicators and other handlers must wear: long sleeved shirt and long pants, chemical-resistant gloves, such as
barrier laminate, butyl rubber, nitrile rubber or Viton? chemical-resistant footwear plus socks, protective eyewear and chemical-resistant headgear for
overhead exposure. For exposures in enclosed areas, a respirator with organic vapor removing cartridge and with a prefilter approved for pesticides
(MSHA/NIOSH approval number prefix TC-23C), or a canister approved for pesticides (MSHA/NIOSH approval number prefix TC-14G) or a NIOSH
approved respirator with an organic vapor (OV) cartridge or canister with any R, P, or HE prefilter. For exposures outdoors, dust/mist filtering respirator
NIOSH/MSHA approval number prefix TC-21C, or a NIOSH approved respirator with any R, P, of HE filter. Discard clothing and other absorbent
materials that have been drenched or heavily contaminated with this product's concentrate. Do not reuse them. Follow manufacturer's instructions for
cleaning and maintaining PPE. If no instructions for washables, use detergent and hot water. Keep and wash PPE separately from other laundry.

ENGINEERING CONTROLS: When handlers used closed systems, enclosed cabs, or aircraft in a manner that meets with the requirements listed
in the Worker Protection Standard (WPS) for agricultural pesticides [40 CFR 170.240 (d) (4-6)], the handler PPE
requirements may be reduced or modified as specified in the WPS.
RESPIRATORY PROTECTION: Not normally required, if vapors or mists exceed acceptable levels, wear a NIOSH approved pesticide respirator with
cartridges for pesticide vapors.
EYE PROTECTION: Chemical goggles or shielded safety glasses.
SKIN PROTECTION: Wear protective clothing: long-sleeved shirts and pants, hat, rubber boots with socks. Wear rubber or chemical-
resistant gloves.
