4. FIRST AID MEASURES
General advice: Have the product container, label or Material Safety Data Sheet with you
when calling the Syngenta emergency number, a poison control centre or physician, or
going for treatment.
Inhalation: Remove to fresh air. If breathing is irregular or stopped, administer artificial
respiration. Keep patient warm and at rest. Call a physician or Poison Control Centre
immediately.
Skin contact: Take off all contaminated clothing immediately. Wash off immediately with
plenty of water. If skin irritation persists, call a physician. Wash contaminated clothing
before re-use.
Eye contact: Rinse immediately with plenty of water, also under the eyelids, for at least 15
minutes. Remove contact lenses. Immediate medical attention is required.
Ingestion: If swallowed, seek medical advice immediately and show the container or label.
Do NOT induce vomiting.
Medical advice: There is no specific antidote available. Treat symptomatically.
5. FIRE-FIGHTING MEASURES
Suitable extinguishing media:
Extinguishing media - small fires: Use water spray, alcohol-resistant foam, dry chemical or
carbon dioxide.
Extinguishing media - large fires: Use alcohol-resistant foam or water spray.
Extinguishing media which must not be used for safety reasons: Do not use a solid
water stream as it may scatter and spread fire.
Specific hazards during fire fighting: As the product contains combustible organic
components, fire will produce dense black smoke containing hazardous products of
combustion (see section 10). Exposure to decomposition products may be a hazard to
health.
Special protective equipment for fire fighters: Wear full protective clothing and
self-contained breathing apparatus.
Further information: Do not allow run-off from fire fighting to enter drains or water courses.
Cool closed containers exposed to fire with water spray.
6. ACCIDENTAL RELEASE MEASURES
Personal precautions: Refer to protective measures listed in sections 7 and 8.
Environmental precautions: Prevent further leakage or spillage if safe to do so. Do not
flush into surface water or sanitary sewer system.
Methods for cleaning up: Contain and collect spillage with non-combustible absorbent
material, (e.g. sand, earth, diatomaceous earth, vermiculite) and place in container for
disposal according to local / national regulations (see section 13).
Additional advice: If the product contaminates rivers and lakes or drains inform respective
authorities.

7. HANDLING AND STORAGE
Advice on safe handling: No special protective measures against fire required. Avoid
contact with skin and eyes. Avoid contact with skin and eyes. When using, do not eat, drink
or smoke. For personal protection see section 8.
Requirements for storage areas and containers: No special storage conditions required.
Keep containers tightly closed in a dry, cool and well-ventilated place. Keep out of the reach
of children. Keep away from food, drink and animal feeding stuffs.
Other data: Physically and chemically stable for at least 2 years when stored in the original
unopened sales containers at ambient temperatures.
8. EXPOSURE CONTROLS/PERSONAL PROTECTION
Exposure Controls
Occupational Exposure Limits ?Hazardous ingredients
Propane-1,2-diol (Propylene glycol), HSE/EH40/2002, LTEL, 8 hr TWA Total (vapour &
particulates) 150 ppm 474 mg/m3. Particulates: 10 mg/m3.
Chlorothalonil, Syngenta Standard; 8 hr TWA 0.1 mg/m3.
ENGINEERING MEASURES
Containment and/or segregation is the most reliable technical protection measure if
exposure cannot be eliminated. The extent of these protection measures depends on the
actual risks in use. If airborne mists or vapours are generated, use local exhaust ventilation
controls. Assess exposure and use any additional measures to keep airborne levels below
any relevant exposure limit. Where necessary, seek additional occupational hygiene
advice.
PERSONAL PROTECTIVE EQUIPMENT
When using this product refer to the label for details. In all other cases, use the following
Personal Protective Equipment:
Protective measures: The use of technical measures should always have priority over the
use of personal protective equipment. When selecting personal protective equipment, seek
appropriate professional advice. Personal protective equipment should be certified to
appropriate standards.
Respiratory protection: A combination gas, vapour and particulate respirator may be
necessary until effective technical measures are installed. Protection provided by
air-purifying respirators is limited.
Use a self-contained breathing apparatus in case of emergency spills, when exposure
levels are unknown, or under any circumstances where air-purifying respirators may not
provide adequate protection.
Hand protection: Chemical resistant gloves should be used. Gloves should be certified to
an appropriate standard. Gloves should have a minimum breakthrough time that is
appropriate to the duration of exposure. The breakthrough time of gloves varies according
to the thickness, material and manufacturer. Gloves should be changed when
breakthrough is suspected.
Suitable material: nitrile rubber.
Eye protection: If eye contact is possible, use tight-fitting chemical safety goggles.
Skin and body protection: Assess the exposure and select chemical resistant clothing
based on the potential for contact and the permeation / penetration characteristics of the
clothing material. Wash with soap and water after removing protective clothing.
Decontaminate clothing before re-use, or use disposable equipment (suits, aprons, sleeves,
boots, etc.). Wear as appropriate: impervious protective suit.

Sensitisation, man: Causes sensitisation
Long term toxicity
Did not show mutagenic effects in animal experiments. Chlorothalonil causes kidney
tumours in rats and mice via a non-gentoxic mode of action secondary to target organ
toxicity. Did not show reproductive toxicity effects in animal experiments. Did not show
teratogenic effects in animal experiments.
No adverse effects in humans are expected at levels below the occupational exposure limit
and when the product is handled and used according to the label.
This information refers to chlorothalonil.
12. ECOLOGICAL INFORMATION
