4. FIRST AID MEASURES
Have the product container, label or Material Safety Data Sheet with you when calling Syngenta (800-888-8372), a poison

Notes to Physician
There is no specific antidote if this product is ingested.
Treat symptomatically.
Persons suffering a temporary allergic reaction may respond to treatment with antihistamines or steroid creams and/or
systemic steroids.
Skin contact paresthesia effects (itching, tingling, burning or numbness) are transient, lasting up to 24 hours. Treat
symptomatically.

None known.
5. FIRE FIGHTING MEASURES
Fire and Explosion
Flash Point (Test Method): Not Applicable
Flammable Limits (% in Air): Lower: Not Applicable Upper: Not Applicable
Autoignition Temperature: Not Available
Flammability: Not Applicable
Unusual Fire, Explosion and Reactivity Hazards
This product is a combustible powder and like all combustible powders can ignite, burn and form explosive mixtures with air
if not handled correctly. Mixtures of powder in air with flammable solvent vapors should be avoided.
This product has a minimum ignition energy between 10 and 30 millijoules. Static electricity, mechanical sparks, open
flames, and certain hot surfaces (greater than 527掳F [275掳C]) can serve as ignition sources for this material.
During a fire, irritating and possibly toxic gases may be generated by thermal decomposition or combustion.
In Case of Fire
Use appropriate extinguishing media for combustibles in the area. Wear full protective clothing and self-contained breathing
apparatus. Evacuate nonessential personnel from the area to prevent human exposure to fire, smoke, fumes or products of
combustion. Prevent use of contaminated buildings, area, and equipment until decontaminated. Water runoff can cause
environmental damage. If water is used to fight fire, dike and collect runoff.
6. ACCIDENTAL RELEASE MEASURES
Product Name: DEMON WP Page: 2
In Case of Spill or Leak
Control the spill at its source. Contain the spill to prevent from spreading or contaminating soil or from entering sewage and
drainage systems or any body of water. Clean up spills immediately, observing precautions outlined in Section 8. Sweep up
material and place in a compatible disposal container. Scrub area with hard water detergent (e.g. commercial products such
as Tide, Joy, Spic and Span). Pick up wash liquid with additional absorbent and place into compatible disposal container.
Once all material is cleaned up and placed in a disposal container, seal container and arrange for disposition.
7. HANDLING AND STORAGE
This product is not considered electrically conductive at low relative humidity.
Handle this material only in electrically conductive equipment. Electrically ground and bond this equipment as well as any
worker who could contact a dust cloud formed of this material. Eliminate the presence of mechanical sparks and other ignition
sources where dust clouds of this material could form. Bulk bags (FIBC) used to contain this material should be either type B or
type C. If type C bags are used make sure they are electrically grounded before powder is discharged from the bag.
Store the material in a well-ventilated, secure area out of reach of children and domestic animals. Do not store food, beverages
or tobacco products in the storage area. Prevent eating, drinking, tobacco use, and cosmetic application in areas where there is a
potential for exposure to the material. Wash thoroughly with soap and water after handling.
8. EXPOSURE CONTROLS/PERSONAL PROTECTION
THE FOLLOWING RECOMMENDATIONS FOR EXPOSURE CONTROLS/PERSONAL PROTECTION ARE INTENDED FOR
THE MANUFACTURE, FORMULATION, PACKAGING AND USE OF THIS PRODUCT.
FOR COMMERCIAL APPLICATIONS AND/OR ON-FARM APPLICATIONS CONSULT THE PRODUCT LABEL.
Prevent eating, drinking, tobacco usage and cosmetic application in areas where there is a potential for
Ingestion:
exposure to the material. Wash thoroughly with soap and water after handling.
Eye Contact: Where eye contact is likely, use chemical splash goggles. Facilities storing or utilizing this material should be
equipped with an eyewash facility and a safety shower.
Skin Contact: Where contact is likely, wear chemical-resistant (such as nitrile or butyl) gloves, coveralls, socks and
chemical-resistant footwear. For overhead exposure, wear chemical-resistant headgear.
Stringent housekeeping measures are necessary to prevent translocation of the material from contaminated
work surfaces to uncontaminated surfaces (railings, doors, etc.). Unprotected contact with such translocated
material can result in paresthesia effects (see Section 11).
Inhalation: A particulate filter respirator may be necessary until effective engineering controls are installed to comply
with occupational exposure limits. Use a NIOSH approved respirator with any HE filter.
Use a self-contained breathing apparatus in cases of emergency spills, when exposure levels are unknown, or
under any circumstances where air-purifying respirators may not provide adequate protection.
Avoid breathing air from drum headspace. Hydrogen cyanide gas may be released during opening and
dispensing, and in case of spills. Use local exhaust ventilation or air-supplied respiratory protection to keep
exposures below the TLV Ceiling Limit.

Reproductive/Developmental Effects
Cypermethrin Technical: There were no cypermethrin-induced effects in fertility in two separate two-litter three (filial)
generation studies in the rat.
Chronic/Subchronic Toxicity Studies
Cypermethrin Technical: NOEL (2-yr) for dogs 5 mg/kg, rats 7.5 mg/kg.
Nervous system effects typical of pyrethroids (motor incoordination, gait abnormalities) in a range of repeated dose
studies (dog and rat). Possible nerve fiber degeneration in 14-day study in rats.
Carcinogenicity
Cypermethrin Technical: Two separate 2-year feeding studies in the rat revealed no evidence of carcinogenicity that
could be attributable to cypermethrin.
Other Toxicity Information
In humans, contact with exposed skin may result in temporary itching, tingling, burning or numbness, called paresthesia.
The effect may result from splash, aerosol, or hot vapor contact, or transfer to the face from contaminated gloves and
hands. The symptoms normally disappear within 24 hours. Face and genital areas are especially susceptible to this effect.
Paresthesia involving the face is also known as "subjective facial sensation" or SFS.
Toxicity of Other Components
Amorphous Silica
Amorphous Silica is listed as an IARC (Group 3) carcinogen not classifiable as a human carcinogen (No Data
Available) with limited animal evidence. Prolonged exposure to amorphous silica may cause damage to
respiratory system and irritation to skin and eyes.
Calcium Silicate
May cause skin or eye irritation upon prolonged or repeated contact.
