SECTION 鈥? 4: FIRST AID MEASURES
IF POISONING IS SUSPECTED, immediately contact the poison information centre, doctor or nearest hospital. Have
the product container, label or Material Safety Data Sheet with you when calling Syngenta, a poison control center or
doctor, or going for treatment. Tell the person contacted the complete product name, and the type and amount of exposure.
Describe any symptoms and follow the advice given. Call the Syngenta Emergency Line [1-800-327-8633 (1-800-
FASTMED)], for further information.
EYE CONTACT: Immediately flush eyes with clean water, holding eyelids apart for a minimum of 20 minutes.
Remove contact lenses, if present, after 5 minutes, then continue rinsing eye. Call Syngenta, a
poison control center or doctor for treatment advice. Obtain medical attention immediately if
irritation persists.
SKIN CONTACT: Immediately remove contaminated clothing and wash skin, hair and fingernails thoroughly with
soap and water. Flush skin with running water for a minimum of 20 minutes. Obtain medical
attention if irritation occurs.
INHALATION: Remove victim to fresh air. If not breathing, give artificial respiration, preferably mouth-to-
mouth. If breathing is laboured, give oxygen. Obtain immediate medical attention.
INGESTION: If swallowed, immediately contact Syngenta, a poison control centre, doctor or nearest hospital for
treatment advice. Provided the patient is conscious, wash out mouth with water. Do not give
anything by mouth to an unconscious person. Do not induce vomiting unless directed by a
physician or a poison control center. If spontaneous vomiting occurs, have victim lean forward
with head down to avoid breathing in of vomitus, rinse mouth and administer water.
NOTES TO PHYSICIAN:
There is no specific antidote if this product is ingested. Treat symptomatically. Contact with eyes may require
specialised ophthalmologic attention.
CAUTION: Contains petroleum distillate - vomiting may cause aspiration pneumonia. Do not induce emesis.
If a large amount has been ingested, lavage stomach carefully to avoid aspiration.
MEDICAL CONDITIONS KNOWN TO BE AGGRAVATED:
Persons with preexisting dermatitis, respiratory disorders, or an allergic history should use extra care in handling
this product.
SECTION 鈥? 5: FIRE FIGHTING MEASURES
Flash point and method: 76.7 潞C.
Upper and lower flammable (explosive) limits in air: Not available.
Auto-ignition temperature: Not Available.
Flammability: Combustible liquid.
Hazardous combustion products: Toxic, flammable fumes are released by thermal decomposition in a fire. Thermal
decomposition products may include oxides of nitrogen, carbon and chlorine.
Conditions under which flammability could occur: Can release vapours that form explosive mixtures at temperatures at
or above the flash point. Heavy vapours can flow along surfaces to distant ignition sources and flash back. Keep fire
exposed containers cool by spraying with water.
Extinguishing media: Use foam, carbon dioxide, dry powder, halon extinguishant or water fog or mist, (avoid use of
water jet). 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,
PRIMO MAXX庐

area, and equipment until decontaminated. Water runoff can cause environmental damage. Contain run-off water with, for
example, temporary earth barriers.
Sensitivity to explosion by mechanical impact: No.
Sensitivity to explosion by static discharge: No.
National Fire Code classification: Class IIIA Combustible Liquid.
SECTION 鈥? 6: ACCIDENTAL RELEASE MEASURES
Personal Precautions: Make sure all personnel involved in the spill cleanup follow good industrial hygiene practices. A
small spill can be handled routinely. Wear suitable protective clothing and eye protection to prevent skin and eye contact.
Use adequate ventilation and wear an air-supplied respirator to prevent inhalation.
Procedures for dealing with release or spill: 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 Sections 7 and 8. Pump or scoop large amounts of liquid into a disposable container.
Absorb remaining liquid or smaller spills with clay, sand or vermiculite. Scoop or sweep up material and place into a
disposal container. Wash area with detergent and water. Pick up wash liquid with additional absorbent and place into
compatible disposal container. On soils, skim off the upper contaminated layer and collect for disposal. Once all material is
cleaned up and placed in a disposal container, seal container and arrange for disposition. Spillages or uncontrolled
discharges into watercourses must be alerted to the appropriate regulatory body.
SECTION 鈥? 7: HANDLING AND STORAGE
Handling practices: KEEP OUT OF REACH OF CHILDREN and animals. Prevent eating, drinking, tobacco use, and
cosmetic application in areas where there is a potential for exposure to the material. After work, rinse gloves and remove
protective equipment. Wash hands thoroughly with soap and water after handling, and before eating, tobacco use,
drinking, or using the toilet. Wash contaminated clothing before re-use and separate from household laundry. Keep
containers closed when not in use. Keep product, wash or rinse water, and contaminated materials out of water, away
from crops, and away from access by people, animals and birds.
Appropriate storage practices/requirements: Store in original container only in a well-ventilated, cool, dry, secure area.
Protect from heat, sparks and flame. Do not expose containers to temperatures above 40 掳C. Keep separate from other
products to prevent cross contamination. Rotate stock. Clean up spilled material immediately.
SECTION 鈥? 8: EXPOSURE CONTROLS/PERSONAL PROTECTION
Applicable control measures, including engineering controls: This product is intended for use outdoors where engineering
controls are not necessary. If necessary, ensure work areas have ventilation, containment, and procedures sufficient to
maintain airborne levels below the TLV. Warehouses, production area, parking lots and waste holding facilities must have
adequate containment to prevent environmental contamination. Provide separate shower and eating facilities.
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.
Personal protective equipment for each exposure route:
General: Avoid breathing dust, vapours or aerosols. Avoid contact with eye, skin and clothing. Wash thoroughly after
handling and before eating, drinking, or handling tobacco.
INGESTION: Do not eat, drink, handle tobacco, or apply cosmetics in areas where there is a potential for exposure to
this material. Always wash thoroughly after handling.
EYES: 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: 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.
INHALATION: Use process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels
below exposure limits. A NIOSH-certified combination air-purifying respirator with an N, P or R 95 or
HE class filter and an organic vapor cartridge may be permissible under certain circumstances where
airborne concentrations are expected to exceed exposure limits. Protection provided by air-purifying
PRIMO MAXX庐

Environmental Fate
The active ingredient, trinexapac-ethyl, has a low bioaccumulation potential, low mobility, and low persistence in
soil and water. The dissipation half-life (DT50) in soil was 1 day for the parent compound via hydrolysis (under moist,
aerobic conditions) and 3-6 days in aquatic systems. The main route of degradation is by hydrolysis as well microbial
degradation and formation of bound residues. The bulk material sinks in water (after 24 h test) and mixes with water
(water based).
