4. FIRST AID MEASURES
Chlorpyrifos is an organo-phosphate insecticide and will inhibit cholineesterase. Symptoms of
overexposure to the active constituent may include headaches, dizziness, incoordination,
muscle twitching, tremors, nausea, abdominal cramps, diarrhoea, sweating, constrictive pupils,
blurred vision, salivation, tightness of the chest, excessive urination and convulsions.
SWALLOWED
The acute oral toxicity of the active constituent is high with reported LD50 measurements for the
active at 115mg/Kg. Because of the low levels of active constituent in this product the risk of
serious poisoning by ingestion is low.
EYES
May irritate eyes.
SKIN
The acute dermal toxicity for the active constituent is low and the formulation makes the risk of
poisoning by this route
very small. The product may cause some skin irritation after prolonged contact and will irritate
broken skin.
INHALED
The risk of poisoning by dust inhalation is low but the dust will irritate the mucous membranes and cause sinuous discomfort. Prolonged exposure to the product may cause headaches and other discomfort as a result of the presence of petroleum solvents. Material Safety Data Sheet – Pyrifos G Rats and mice which were administered the active ingredient in long term studies showed no
increase in tumours compared to the control. Studies in rats and rabbits indicate that the active
constituent does not cause birth defects or interfere with reproduction. There is no known
evidence of genetic change or accumulation of the active constituent in the body.
SWALLOWED
If swallowed contact a doctor or the National Poisons Centre (0800 764 766)
EYES
If in eyes hold eyelids open, flood with water for at least 15 minutes and see a doctor if irritation
persists.
SKIN
Wash skin with soap and water.
INHALED
Remove victim to fresh air and seek medical advice if effects persist. If breathing difficulties
become acute give oxygen.
ADVICE TO DOCTOR:
Chlorpyrifos is a cholinesterase inhibitor. Atropine by injection or Atrovent/ipratropium by airway
puffs are the desirable antidotes. Oximes such as 2 PAM/protopam may be therapeutic if used
early but only in conjunction with atropine.
5. FIRE FIGHTING MEASURES

Product is not highly flammable although the small amount of petroleum solvent will support
short term combustion.
