Attention:
hours after exposure.
Symptoms of poisoning.
Mild poisoning - headache, blurred vision, weakness, sweating, mild chest
pain, nausea and vomiting.
Severe poisoning - cyanosis (blueness of the skin), muscular twitching,
spasms, miosis (pinpoint pupils) and respiratory paralysis.
Repeated minor exposure may have a cumulative poisoning effect.
Treatment
Basic aid, decontamination, symptomatic treatment and administration of
antidote.
Antidote : Atropine sulphate, possibly in conjunction with toxogonin or
obidoxime (PAM). Monitor respiratory, cardiac and central nervous system
function. Monitor red blood cell and plasma cholinesterase levels. Administer
oxygen if necessary. Watch for pulmonary oedema and delayed neurological
symptoms. Continued absorption of chlorpyrifos may occur and relapse may
occur after initial improvement. VERY CLOSE SUPERVISION OF THE
PATIENT IS INDICATED FOR AT LEAST 48 HOURS.
Contraindications : Adrenergic derivatives. DO NOT give morphine or
tranquilisers.

5) FIRE FIGHTING MEASURES continued

Fire fighters should wear full protective gear, including self-contained
Precautions for
breathing apparatus (AS/NZS 1715/1716). Keep unnecessary people away. If
fighting fires
it can be done safely remove intact containers from the fire. Bund area with
sand or earth to prevent contamination of drains or waterways. Dispose of
extinguishing agent and spillage safely later. Do not release contaminated
water into the environment.

6) ACCIDENTAL RELEASE MEASURES

Avoid contact with spilled material or contaminated surfaces. Do not smoke, eat or drink during the
clean up process. Wear personal protective clothing and equipment as detailed in Section 8
PERSONAL PROTECTION. Keep people and animals away. Contain spill and absorb with earth,
sand, clay or other absorbent material. Prevent spilled material from entering drains or watercourses.
Collect and store in properly labelled drums for safe disposal. Clean floor with a damp cloth and place
it in the drum. Seal drums and label ready for safe disposal. Deal with all spillages immediately. If
contamination of drains, streams, watercourses etc is unavoidable warn the local water authority.
Chlorpyrifos can be hydrolysed in water by adjusting the pH to alkaline.

10) STABILITY AND REACTIVITY


Stable at ambient temperatures and pressures. Avoid
Chemical stability:
heating above 40潞C. Chlorpyrifos technical undergoes
exothermic decomposition at approximately 130OC which
can lead to higher temperatures and violent decomposition
if heat generation is not removed. Stable in neutral or
slightly acidic conditions at room temperature. Rate of
hydrolysis increases as temperature and pH are raised.
Hydrolysed by strong alkaline material e.g. Bordeaux mix.
Hazardous decomposition products include various oxides
and derivatives of phosphoric acids, sulphur, phosphorous,
nitrogen, carbon dioxide and hydrochloric acid. As for
many organic powders or crystals, if a severe dusty
condition occurs, this material may form explosive
mixtures with air.

Avoid extreme high or low temperatures.
Conditions to avoid:

Strong acids and strong bases.

May be a skin sensitiser
Sensitisation:

Chronic:
Not carcinogenic, not mutagenic, not teratogenic in animal experiments.
Repeated or prolonged exposure to organophosphates may result in the same effects as acute exposure
including the delayed symptoms. Other effects reported in workers repeatedly exposed include
impaired memory and concentration, disorientation, severe depressions, irritability, confusion,
headache, speech difficulties, delayed reaction times, nightmares, sleepwalking, and drowsiness or
insomnia. An influenza-like condition with headache, nausea, weakness, loss of appetite, and malaise
has also been reported . When technical chlorpyrifos was fed to dogs for 2 years, increased liver
weight occurred at 3.0 mg/kg/day. Signs of cholinesterase inhibition occurred at 1 mg/kg/day. Rats
and mice given technical chlorpyrifos in the diet for 104 weeks showed no adverse effects other than
cholinesterase inhibition . Two-year feeding studies using doses of 1 and 3 mg/kg/day of chlorpyrifos
in rats showed moderate depression of cholinesterase. Cholinesterase levels recovered when the
experimental feeding was discontinued. Identical results occurred in a 2-year feeding study with dogs.
No long term health effects were seen in either the dog or rat study . A measurable change in plasma
and red blood cell cholinesterase levels was seen in workers exposed to chlorpyrifos spray. Human
volunteers who ingested 0.1 mg/kg/day of chlorpyrifos for 4 weeks showed significant plasma
cholinesterase inhibition

13) DISPOSAL CONSIDERATIONS
Triple or preferable pressure rinse containers before disposal. Add rinsings to the mixing tank. Do not
dispose of undiluted chemical 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 500mm 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.
