4. FIRST AID MEASURES
Skin contact: Remove contaminated clothing. Wash contaminated skin with soapy water. If
skin irritation develops, get medical attention. Wash clothing thoroughly before re-use.
Eye contact: Rinse eye(s) with clean running water for 15 mins. Get medical attention.
Ingestion: Rinse mouth. Give water to drink if patient is conscious. DO NOT induce
vomiting. If vomiting occurs ensure patient can breathe, then give water to drink. Get medical attention.
Atropine tablets 0.6mg and activated charcoal should be available in the area where this product is used, or in a
nearby unlocked medicine cabinet. If swallowed, splashed on skin or inhaled, contact a Poisons
Information Centre or a doctor at once. Remove any contaminated clothing and wash skin thoroughly. If
swallowed, use of activated charcoal may be advised. Give atropine if instructed. The usual instruction is
to give one atropine tablet every 5 minutes until dryness of the mouth occurs.
If breathing has stopped, trained personnel should begin artificial respiration or, if the heart has stopped,
cardiopulmonary resuscitation (CPR) immediately.
Advice to doctor: This chemical is a cholinesterase inhibitor. Treat appropriately.
5. FIRE FIGHTING MEASURES

6. ACCIDENTAL RELEASE MEASURES
Emergency procedures: Wear protective equipment to prevent skin and eyes being affected.
Evacuate unprotected and unnecessary personnel from area of spill.
If material is leaking from a container, stop the leak only if this can be done safely.
Prevent spillage entering drains or watercourse.
Methods for containment & cleanup: Vermiculite, Sand, Soil is a suitable absorbent, especially soils high
in clay.
Soil can be used to form bunds to contain spillage.
Contaminated soil should be collected for disposal at a suitable landfill.
Contaminated area and tools should be washed down with hypochlorite bleach.
Personal protective equipment and clothing should be washed with soapy water.
7. HANDLING AND STORAGE
Handling: Keep away from food, drink, and animal feedstuff.
KEEP OUT OF REACH OF CHILDREN.

8. EXPOSURE CONTROLS
National exposure standards: Exposure Limits TWA 0.2 mg/m3, STEL not set.
Biological limit values: The ADI for Chlorpyrifos is set at 0.003mg/kg/day. The corresponding NOEL is
set at 0.03mg/kg/day.
Engineering measures: Use assisted ventilation in enclosed spaces if needed, especially storage areas.
Personal protection equipment:
Eye/face protection: Goggles or glasses to AS 1366, AS/NZS1337
Hand/skin protection: Overalls, PVC gloves and apron, face shield
Respiratory protection: Should not be necessary under normal conditions. If spray mist may be

11. TOXICOLOGICAL INFORMATION
Acute toxicity: Oral LD50 for rats is 135-163 mg/kg, for rabbits is 1000-2000 mg/kg.
Inhalation LC50 for rats is 0.2 mg/L.
Chronic toxicity: NOEL for rats is 1 mg/kg bw for 2 years.
Possible routes of exposure: Inhalation of spray mist is the most likely cause of exposure. Skin absorption
from spilled concentrate is also a possibility.
Range of effects. This product is an organophosphate insecticide that is a cholinesterase inhibitor. Excessive
exposure can result in symptoms consistent with its main mode of action. Its main hazard is from short
term acute poisoning and medium effects from depressed cholinesterase levels. It is not a significant
carcinogen.
Symptoms of acute exposure to organophosphate or cholinesterase-inhibiting compounds may include the
following: numbness, tingling sensations, incoordination, headache, dizziness, tremor, nausea, abdominal
cramps, sweating, blurred vision, difficulty breathing or respiratory depression, and slow heartbeat. Very
high doses may result in unconsciousness, incontinence, and convulsions or fatality
Dose/conc./conditions likely to cause injury: 10 to 20 mls.
Delayed effects if any: Onset of symptoms is usually rapid, so delayed effects are not seen. Generally
recovery is fairly rapid once exposure has ceased.
Relevant negative data: Not known to be carcinogenic, mutagenic, or teratogenic.
12. ECOLOGICAL INFORMATION
Ecotoxicity:
Aquatic organisms: Very toxic to fish, crustaceans, insects and arachnids.
Flora: Not toxic.
Fauna: Moderate to very toxic.
Soil organisms: Low toxicity to worms, very toxic to insects and arachnids.
Bees: Very toxic.
Long term:
Ozone effects: None recorded.
Persistence/degradation: Degrades in soil with a half-life measured in weeks rather than months.

Bioaccumulative potential: Unknown but probably low.
13. DISPOSAL CONSIDERATIONS
Product: Whenever possible, product should be used for its intended purpose, even if
reclaimed from spillage (reclaimed product must be uncontaminated).
Containers: Whenever possible, follow directions given on container.
If not available, triple or pressure rinse plastic or metal containers before disposal. Recycle containers if
