SECTION 4: First Aid Measures
Symptoms of exposure:
Snare Termiticide may cause moderate eye irritation and/or corneal injury, vapours may irritate the eyes. Skin:
Prolonged exposure may cause moderate skin irritation. If swallowed in large amounts serious injury may
occur even death.
If aspirated (liquid enters the lung) may cause lung damage or even death due to chemical pneumonia. Inhalation
: Symptoms typical of organophosphate-type cholinesterase inhibition may occur. Excessive exposure
to the liquid hydrocarbon vapour may cause respiratory irritation and central nervous system depression. Signs
and symptoms of central nervous system depression in order of increasing exposure are headache, dizziness,
drowsiness, and incoordination. Systemic (other target organ effects):
Excessive exposure may cause organophosphate type cholinesterase
inhibition. Signs and symptoms of excessive exposure to chlorpyrifos may include headache, dizziness,
incoordination, muscle twitching, tremors, nausea, abdominal cramps, diarrhoea, sweating, pinpoint pupils, blurred
vision, salivation, tearing, excessive urination, tightness in the chest and convulsions. The liquid hydrocarbon has
been reported to cause liver, kidney, kidney, and blood effects at high exposure levels.
General: Consult the Poisons Information Centre (Ph: 13 11 26) or a Doctor in every case of suspected
chemical poisoning. Never give fluids or induce vomiting if a patient is unconscious or convulsing
regardless of cause of injury. If breathing difficulties occur seek medical attention immediately.
Atropine tablets 0.6mg should be available in the area where this product is used, or in a nearby unlocked medicine
swallowed, give one atropine tablet every 5 minutes until dryness of the mouth occurs. Get to
If poisoned by skin absorption or through lungs, remove any contaminated clothing and wash skin thoroughly and give one atropine tablet every 5 minutes until dryness of the mouth occurs. If safety shower is available, use it promptly. Get to a doctor or hospital quickly.
If in eyes, hold eyes open and flood with water for at least 15 minutes and see a doctor. Ensure irrigation under eyelids by occasionally lifting them. Do not try to remove contact lenses unless trained.
If affected, remove from contaminated area to fresh air. If breathing is difficult give oxygen and if necessary artificial respiration. Get to a doctor or hospital quickly.
Advice to Doctor
: Chlorpyrifos is a cholinesterase inhibitor. Atropine by injection or ATROVENT/ipratropium by
airway puff are the preferred antidotes. Oximes such as 2 PAM/ protopam, may be therapeutic if used early but only if used in conjunction with atropine. Snare contains liquid hydrocarbon solvents. If lavage is performed endotracheal or oesophagioscopic control is advisable
Workplace facilities (manufacturing and packaging):
Provide emergency showers and eyewash facilities.
SECTION 5: Fire Fighting Measures
Combustible liquid. (Flashpoint 66 ˚C by PMCC)
Upper Value: 6.0%, Lower Value: 0.9% (solvent)
This product is unlikely to spontaneously decompose.
Materials to avoid:
Hazardous Decomposition Products:
During a fire smoke may contain the original material in addition to unidentified toxic and/or irritating compounds. Hazardous combustion
products may include and are not limited to sulphur oxides, phosphorous compounds, nitrogen oxides, hydrogen chloride, carbon monoxide and/or carbon dioxide
Fire & Explosion Hazards:
Combustible liquid. There is a moderate risk of an explosion from this product if it is involved in a fire. Fire decomposition products from this product may form toxic and corrosive mixtures in confined spaces.
Special Fire Fighting procedures:
Evacuate personal to a safe area. Stay upwind. Keep out of low areas where gasses (fumes) can accumulate. Eliminate ignition sources. Burning liquids may be extinguished by dilution with water. Do not use direct water stream to prevent spread of fire. Use water spray to
cool fire exposed containers. Do not allow water from fire-fighting to enter water supplies, or drainage systems
Protective equipment for fire-fighters:
Wear positive-pressure self-contained breathing apparatus and full protective clothing (includes fire fighting helmet, coat, pants, boots and gloves. If protective equipment is not available or not used, fight fire from a protected location or safe distance.
Carbon dioxide, dry chemical, foam, water fog or fine spray. Alcohol resistant foams (ATC type) are preferred if available because uncontrolled water can spread possible contamination. General-purpose synthetic foams (including AFFF) or protein foams may function, but much less effectively.
Media to be avoided:
SECTION 6: Accidental Release Measures
Wear appropriate protective equipment (see Section 8). Clear area of all unprotected personnel. Prevent
entry of chemical or used/damaged containers into sewers, drains, streams or waterways. If necessary,
inform the police and the relevant Environmental Agency.
For clean-up of a spill from a single shipping pack soak up with sand or other non-combustible absorbent material and place into containers for disposal. If applicable wash area with a solution of bleach (sodium hypochlorite) prepared according to the bleach label instructions.
Eliminate all sources of sparks or open flame. Wear protective clothing. Stop further release or spread of spilled material. For clean up of multiple shipping packs, place leaking container into a salvage drum and pump or scoop up liquid into the salvage drum. Absorb remaining liquid as for small spills. Place clean-up material and damaged containers into salvage drums for disposal. If applicable, wash the area with a solution of bleach (sodium hypochlorite) prepared according to the bleach label instructions. On soils, skim off the upper contaminated layer and collect it for disposal. If further information is required, telephone 000 and the emergency contact number or Dow AgroSciences Australia.
SECTION 7: Handling and Storage
Keep out of reach of children and animals. Do not swallow. Do not get in eyes, on skin or on clothing. Avoid
breathing spray mist or vapours. After work, remove protective equipment, and wash hands before eating,
smoking, drinking or using the toilet. Clean up spilled material immediately, and wash clothes, equipment and work
area after use. .
Keep out of reach of children and animals. Store in tightly closed original containers in a cool, well-ventilated area
set aside for hazardous materials and out of direct sunlight. Do not store with food, feedstuffs, fertilisers or seeds.
SECTION 8: Exposure Control/Personal Protection
These precautions are suggested for conditions where a potential for exposure exists. Emergency conditions may
require additional precautions
A time weighted average (TWA) has been established for chlorpyrifos of 0.2mg/m3. The corresponding STEL level
is "not set". The exposure value at the TWA is the average airborne concentration of a particular substance when
calculated over a normal 8 hour working day for a 5 day working week. The ADI (Acceptable Daily Intake) for
chlorpyrifos is set at 0.003mg/kg/day. The corresponding NOEL (No-observable-effect-level) is set at
0.03mg/kg/day. Values taken from Australian ADI List, January, 2001.
The supplier of the liquid hydrocarbon recommends an 8-hour time weighted average (TWA) exposure of 500
mg/m3 total vapour/aerosol (approx. 100 ppm vapour) or 5 mg/m3 stable aerosols. ENGINEERING CONTROLS
In industrial situations, concentrated values below the TWA value should be maintained. Values may be reduced
by process modification, use of local exhaust ventilation, capturing substances at the source, or other methods. If
airborne concentrations of mists, dusts or vapours are believed to be high, it is advisable to modify the process or
environment to reduce the problem.
Personal Protection for manufacturing and packaging.
Atmospheric levels should be maintained below the exposure guidelines. When respiratory protection is required
use an approved air-purifying or positive –pressure supplied-air respirator depending of the potential airborne
concentration. For emergency and other conditions where the exposure guideline may be greatly exceeded, use
an approved positive-pressure self-contained breathing apparatus or positive-pressure airline with auxiliary self-
contained air supply. Skin protection
Use protective clothing impervious to this material. Selection of specific items such as face shield, gloves, boots,
apron, or full body suit will depend on the operation. Remove contaminated clothing immediately, wash skin area
with sap and water, and launder clothing before reuse. Contaminated leather items, such as shoes, belts and
watchbands, should be removed and destroyed. Eye/face protection
Use chemical goggles. If vapour exposure causes eyes discomfort, use an approved full-face respirator.
Personal Protection for applicators and all other handlers
Personal Protection for application and all other handlers.

Materials to avoid:
Avoid contact with oxidizing materials and bases.
Hazardous Decomposition Products:
Hazardous decomposition products depend upon temperature, air supply and the presence of other materials. Hazardous decomposition products may include and are not limited to hydrogen chloride, organic sulphides and sulphur dioxide. Toxic gases are released during decomposition
SECTION 11: Toxicological Information
Based on the individual components present in the formulation.
The rat oral LD50 is 230 – 310 mg/kg (moderately toxic). Eye:
May cause temporary, moderate eye irritation and/or corneal injury. Vapours may irritate the eyes.
Prolonged exposure may cause skin irritation. Skin sensitisation is not known to occur. The dermal LD50
(rabbit) is above 2000 mg/kg. Toxicity is low with short term contact and less than 3% of applied chlorpyrifos is
The aerosol 4 hour LC50 for a similar material is 2.7 mg/L. No adverse effects are anticipated from a
single short-time exposure to vapour.
Based on a majority of negative data and some equivocal or marginally positive results, chlorpyrifos
is considered to have minimal mutagenic potential. No information has been found for the other components.
Terratology (birth defects)
Chlorpyrifos did not cause birth defects in laboratory animals. No information found
for the other components.
Reproductive and Developmental toxicity:
Chlorpyrifos did not interfere with fertility in reproduction studies in
laboratory animals. Some evidence of toxicity to the offspring occurred, bur only at a hose high enough to produce
significant toxicity to the parent animals. No information was found for the other components.
Chlorpyrifos did not cause cancer in laboratory animals. The MSDS for the liquid hydrocarbon
reports that skin tumours have occurred in laboratory mouse skin painting tests, but these have usually been
associated with a high level of skin irritation and further tests have determined that the irritation causes the
tumours. Therefore, if the precautions are taken to minimise repeated of prolonged skin contact which could cause
irritation there should be no carcinogenic hazard to humans. No information was found for the other components.
SECTION 12: Ecological Information
Based on information for chlorpyrifos.
chlorpyrifos is highly toxic to birds on a dietary basis (LC50 between 50 and 500 ppm
The liquid hydrocarbon is practically non-toxic to birds on an acute and dietary basis ( LD50 > 2000 mg/kg and
LC50 > 5000 ppm). No information was found for the other components.
Chlorpyrifos is very highly toxic to aquatic organisms on an acute basis (LC50 /EC50 < 0.1
mg/L in most sensitive species). The liquid hydrocarbon is moderately toxic (LC50 /EC50 between 1 and 10
mg/L in most sensitive species). No information was found for the other components.
Chlorpyrifos is very highly toxic to terrestrial non-vertebrates (Honey bees topical LD50 is 0.114 µg/bee)
No information was found for the other components.
Chlorpyrifos is practically non toxic to earthworms (14 day LC50 210 – 313 mg/kg soil) No
information was found for the other components.
• Breakdown of Chemical in Soil and Groundwater:
The breakdown of chlorpyrifos in soils is to largely
dependant on soil concentration, soil type, and pH. It will degrade faster under alkaline conditions, and in soils with higher moisture content and higher temperature. At termiticide use rates, the half-life is approximately 380 days. Chlorpyrifos adsorbs strongly to soil particles and it is not readily soluble in water. It is therefore immobile in soils and unlikely to leach or to contaminate groundwater. No information was found for the other components.
• Breakdown of Chemical in Surface Water:
Chlorpyrifos readily adsorbs to suspended sediment and
bottom materials. Volatilization is probably the primary route of loss from water. The photolysis half-life in water is 3-4 weeks. Hydrolysis increases with temperature and in alkaline waters Most of the dissolved chlorpyrifos (approximately 1 ppm) is hydrolysed in 12 hours to 6 days depending on pH. No information was found for the other components.
• Breakdown of Chemical in the atmosphere:
Chlorpyrifos is estimated to have a tropospheric half-life of
• Breakdown of Chemical in plants:
Chlorpyrifos remains on the plant surfaces for approximately 10 – 14
days. No information was found for the other components.
SECTION 13: Disposal Considerations
Contaminated material must be disposed of in accordance with all State and/or local authority requirements.
Triple or preferably pressure rinse containers before disposal. Add rinsings to spray tank. Do not dispose of
undiluted chemicals on site. If recycling, replace cap and return clean containers to recycler or designated
collection point. 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. Rinsate/rinse water should be disposed of in accordance with appropriate State legislation and should
preferably be sprayed on to an application site or added as up to 10% of the diluent the next time this product or
another similar termiticide is used. Do not put down sewers, gutters or storm water drains. In some States wastes
can only be buried at a licensed landfill.
If disposing of unwanted product, contact Dow AgroSciences or your local authority.
