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. Induce vomiting if patient is
conscious. If vomiting occurs in an unconscious patient ensure they can breathe. Give CPR if
needed. Get medical attention.
Advice to doctor: Gastric lavage if there are no signs of impending convulsions.
Cautious administration of short-acting anticonvulsant drug if convulsions appear imminent.
General supportive measures for central nervous system depression.
If hypotension appears, search vigorously for a contributing cause (e.g. dehydration, electrolyte balance,
acidosis, myocardial disturbances and hyperpyrexia).
As appropriate, treat dehydration, electrolyte disturbances, acidosis, and hyperexia.
To promote excretion, initiate alkaline diuresis, as in salicylate poisoning by injecting sodium
bicarbonate, intravenously, until urine pH exceeds 7.5 and then infuse mannitol; renal clearance
rises sharply as urine pH rises above 7.5.
If cardiac disturbances are suspected, monitor ECG continuously if possible.
Prepare to deliver defibrillating shocks in the event of ventricular fibrillation.
If hypotension intensifies, a trial with a vasopressor drug may be appropriate.
Adrenalin (epinephrine) should be avoided because of possible fibrillation.
If myotonia appears, a trial with quinidine maybe helpful.
Physiotherapy may be necessary for motion disorders associated with peripheral neuritis, myopathy or
brain stem dysfunction.

5. FIRE FIGHTING MEASURES
Suitable extinguishing media: Carbon dioxide, dry chemical, foam, water fog.
Unsuitable extinguishing media: Water stream.
Special hazards in fire: Product is flammable. Combustion may release carbon dioxide, nitrogen oxides,
and/or chlorine compounds.
Required special protective equipment for fire-fighters: Wear self contained breathing apparatus if in
enclosed space.

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.

DO NOT store with food, seed, or animal feedstuff.
8. EXPOSURE CONTROLS
National exposure standards: Not established, use default of 10 mg
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
encountered, a particulate filter to AS/NZS 1715 should be worn.

10. STABILITY AND REACTIVITY
Chemical stability: Normally stable. Will hydrolyse in contact with acidic or alkaline solutions.
Active may degrade in UV light.
Conditions to avoid: Very high or low temperatures.
Materials to avoid: Oxidising agents, acids and alkalies.
Hazardous decomposition products: May emit hydrogen chloride and/or chlorine oxides in fire.
Hazardous reactions: Will not polymerise or otherwise react spontaneously.
11. TOXICOLOGICAL INFORMATION
(These comments apply largely to 2,4-D acid. Esters may be slightly less damaging).
Acute toxicity: Unknown. 2,4-D acid has Oral LD50 for rats of 639-765 mg/kg.
Chronic toxicity: Unknown. 2,4-D has 2y NOEL for rats of 5 mg/kg.
Possible routes of exposure: Inhalation of spray mist is the most likely cause of exposure.
Range of effects. Excessive exposure may affect human health as follows:
Skin contact: May cause inflammation of the skin.
May accentuate any pre-existing dermatitis condition.
Entry into blood-stream, through, for example, cuts, abrasions or lesions, may produce systemic injury
with harmful effects.
Toxic effects may result from skin absorption. 2,4-D esters can be absorbed through the skin of
humans. Severe peripheral neuropathy may follow causing limb paralysis and loss of sensation.
Fatigue, nausea, vomiting, anorexia, diarrhoea and swelling occur, followed by "pins and needles", pain
and paralysis. Disability will be on-going.
Eye contact: Can cause severe eye damage.
Corneal injury resulting from 2,4-D exposure may be slow to heal.
Inhalation/ingestion: May cause irreversible damage of organs if swallowed once.
Chlorphenoxy compounds irritate the digestive system, causing nausea and vomiting, chest pain, and
diarrhoea.
Large doses can result in mineral imbalance, temperature changes, hyperventilation, low blood
pressure, dilated blood vessels, damage to the heart and liver with death of white blood cells, and
convulsions.
Massive doses can cause ventricular fibrillation followed by death. If death is delayed, there may be
sluggishness followed by spastic changes in muscles and inco-ordination. Severe cases cause
apathy, weakness in the legs, regular muscle spasms and coma.
Subacute poisonings cause severe nosebleeds, bleeding from the mouth and irritation of the eye and
nose.
2,4-D in not metabolised and is excreted only slowly from the body, in the urine.
Can cause respiratory irritation.
Dose/conc./conditions likely to cause injury: Ingestion of more than 10 mls could cause acute poisoning.
Delayed effects if any: May cause asthma like symptoms, nausea, liver changes, skin eruptions, irritation of
the airways and eyes, as well as nervous changes.
Suspected carcinogen/mutagenacin.

13. DISPOSAL CONSIDERATIONS
Product: Whenever possible, product should be used for its intended purpose, even if
reclaimed from spillage (reclaimed product must be uncontaminated). Otherwise treat as rinsings.
Containers: Whenever possible, follow directions given on container.
If not available, triple or pressure rinse plastic or metal containers before disposal. Recycle containers if
possible (replace cap and return clean containers to recycler or designated collection point). Treat
rinsings as for product above.
If not recycling, break, crush or puncture and bury empty containers in a local authority landfill. If no
landfill is available, bury the containers below 500 mm in a disposal pit specifically marked and set up
for this purpose clear of waterways, desirable vegetation and tree roots. Empty containers and product
should not be burnt.
Rinsings: If possible, add rinsings to spray tank and use as per product directions. If not,
spray onto suitable bare ground (firebreaks etc). Otherwise drain to a chemical sump/sullage pit.
