Poison schedule - S5.
Mammalian toxicity - Toxic to dogs. If dogs eat pellets DO NOT give dogs ipecac syrup. Take dog to a vet immediately if it has eaten pellets.
Acute oral LD50 - >500 to <1000 mg/kg (rats), [For comparison table salt is 3000 mg/kg]
Acute dermal LD50 - >2000 mg/kg (rabbit).
Skin - Not expected to irritate skin. Non irritant. Not a sensitiser.
Eye - Irritant.
Vapour inhalation - LC50 - >.224 mg/L air (rat).
Chronic oral toxicity NOEL - ppm for two years.
Not mutagenic or teratogenic (i.e. does not cause cancer). Methiocarb is considered to be a developmental toxicant in the USA.
Acceptable Daily Intake (ADI) -
23. TOXICITY SYMPTOMS:
Symptoms usually occur 1-3 hours after exposure. Onset of symptoms may be delayed and may persist for several weeks.
Mild intoxication may cause headache, blurred vision, weakness, sweating, mild chest pain, nausea and vomitting.
Severe intoxication may cause cyanosis(blueness of skin), muscular twitching, spasms, miosis(pinpoint pupils) and respiratory paralysis.
May irritate eyes.
24. FIRST AID:
If SWALLOWED - give one atropine tablet every 5 minutes until dryness of the mouth occurs (Ring 13 11 26 Poisons Information Centre to confirm atropine administration). Go to a hospital quickly. Don't give anything by mouth to a semi conscious or unconscious person.
If in EYES - Irrigate for 15 minutes with plenty of water.
If on SKIN - Rinse with plenty of water, remove contaminated clothing, wash with soap and water. Give one atropine tablet every 5 minutes until dryness of the mouth occurs (Ring 13 11 26 Poisons Information Centre to confirm atropine administration). Go to a hospital quickly.
If INHALED - Remove patient to fresh air. Give one atropine tablet every 5 minutes until dryness of the mouth occurs (Ring 13 11 26 Poisons Information Centre to confirm atropine administration). Go to a hospital quickly. If breathing stops apply artificial respiration.
If patient has symptoms or is concerned contact a doctor immediately.
Advice to doctor - Treat symptomatically. Antidote is atropine sulfate. Atropine shoud not tbe given to a cyanosed person. Oximes are contraindicated. Monitor cardiac, respiratory and central nervous system functions. Monitor red blood cell and plasma cholinesterase levels. Administer oxygen if nesessary. Watch for pulmonary oedema and delayed neurological symptoms.
Contraindications - Oximes, adrenergic derivatives. Never give patient morphine, theophylline or theophylline-ethylenediamine. Large amounts of intravenous fluids are generally contraindicated because of the threat of pulmonary oedema.
