HEALTH HAZARD DATA
HEALTH EFFECTS
The active ingredient in Lorsban 500 EC is the organophosphate compound chlorpyrifos. Excessive exposure may
cause organophosphate type cholinesterase inhibition. Symptoms of excessive exposure to chlorpyrifos may
include pallor, nausea, vomiting, diarrhea, abdominal cramps, headache, dizziness, eye pain, blurred vision,
constriction or dilation of the eye pupils, tears, salivation, sweating, and confusion.
The information provided below is from studies conducted with a formulation similar to Lorsban 500EC.
Acute
Swallowed:
The oral LD50 (rat) is 230 to 310 mg/kg (moderately toxic).
Will cause temporary, moderate eye irritation.
The dermal LD50 (rabbit) is above 2000 mg/kg. Toxicity is low and less than3% of applied is absorbed. Prolonged contact may result in absorption ofharmful amounts.
Inhaled:
The inhalation LC50(rat) is 2000 to 2400 mg/m3 for 4 hours exposure(moderate to low toxicity). Excessive exposure to spray mist may beharmful. Prolonged exposure to solvent vapour from the concentrate maycause eye and respiratory tract irritation, headache, dizziness and narcoticeffects.
Chronic
Possible chronic health effects from exposure to Lorsban 500 EC are based on studies usingthe active ingredient. Chlorpyrifos has been shown not to cause cancer and does not interferewith reproduction and does not cause genetic damage or birth defects. Chlorpyrifos is rapidlymetabolised and excreted, and as a result, does not accumulate in the body. Repeated minorexposure may have a cumulative poisoning effect. The ingredients are not listed ascarcinogenic in NOHSC’s document “Exposure Standards for Atmospheric Contaminants in theOccupational Environment” (May 1995).
PERSONAL PROTECTION AND SAFETY DIRECTIONS
Product is poisonous if absorbed by skin contact, inhaled or swallowed. Repeated minor exposure may have a
cumulative poisoning effect. Obtain an emergency supply of atropine tablets 0.6 mg. Will irritate eyes and skin.
Avoid contact with eyes and skin. Avoid inhaling spray mist. When opening the container, preparing the spray or
bait, or using the prepared spray or bait, wear cotton overalls buttoned to the neck and wrist and a washable hat,
elbow-length PVC gloves, face shield or goggles. If product on skin, immediately wash area with soap and water.
After use and before eating, drinking or smoking, wash hands, arms and face thoroughly with soap and water. After
each day's use wash gloves, face shield or goggles and contaminated clothing.
FIRST AID
General: Consult The National 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
cabinet.
Swallowed:
If swallowed, give one atropine tablet every 5 minutes until dryness of the mouth occurs. Get toa doctor or hospital quickly.
If poisoned by skin absorption or through lungs, remove any contaminated clothing and washskin 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. Ensureirrigation under eyelids by occasionally lifting them. Do not try to remove contact lenses unlesstrained.
Inhalation:
If affected, remove from contaminated area to fresh air. If breathing is difficult give oxygen and ifnecessary 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 therapeuticif used early but only if used in conjunction with atropine. Lorsban 500 EC contains petroleum-like solvents. If lavage is performed endotracheal or oesophagioscopic control is advisable.
PRECAUTIONS FOR USE
EXPOSURE STANDARDS
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.
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
you believe airborne concentrations of mists, dusts or vapours are high, you are advised to modify the process or
environment to reduce the problem.

OTHER INFORMATION
ECOTOXICITY DATA
Chlorpyrifos is highly toxic to birds, fish, aquatic invertebrates and estuarine and marine organisms. Chlorpyrifos is
also highly toxic to honeybees and should not be used when bees are actively collecting pollen and nectar.
Chlorpyrifos is moderately toxic to pets and livestock and has low toxicity to earthworms
ENVIRONMENTAL FATE
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. The soil half-life of chlorpyrifos for concentrations
representing agricultural use practices approximates 70 days depending on sunlight, soil type and climatic
conditions. Adsorbed chlorpyrifos is subject to degradation by UV light, chemical hydrolysis and by soil microbes.
In situations where the product accidentally enters water bodies, chlorpyrifos will bind to organic particles in thewater and sediment. The concentration of chlorpyrifos that dissolves (approx. 1ppm) is hydrolysed rapidly in twelvehours to six days depending on pH. Both adsorbed and dissolved chlorpyrifos are also lost from water throughvolatilization and to a lesser extent photodegradation. Chlorpyrifos is degraded eventually into carbon dioxide andsimple organic molecules.
