Poison schedule - S6
Summary:
Details:
Poison schedule - S6
Mammalian toxicity -
Acute oral LD50 - 380 mg/kg (rats), Harmful. [For comparison table salt is 3000 mg/kg]
Acute dermal LD50 - > 3000 mg/kg (rabbit). Harmful.
Skin - Irritating.
Eye - Irritating.
Vapour inhalation - LC50 - > mg/L air (rat).
Chronic oral toxicity NOEL - ppm for two years.
Not carcinogenic, oncogenic, mutagenic or teratogenic (i.e. does not cause cancer or reproductive problems).
Acceptable Daily Intake (ADI) -

23. TOXICITY SYMPTOMS:

Most field cases result from skin absorption.
Mild exposure - Headache, Blurred vision, weakness, giddiness, sweating, mild chest pain, nausea and vomiting.
Severe exposure - Cyanosis, muscular twitching, spasms, miosis and respiratory paralysis.

24. FIRST AID:

If SWALLOWED - The concentrate is dangerous. Induce vomiting preferably with Ipecac syrup APF and give one atropine tablet every 5 minutes until dryness of mouth occurs.
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 mouth occurs. See a doctor immediately.
If INHALED - Remove patient to fresh air. See a doctor immediately.
If patient has symptoms or is concerned contact a doctor immediately.
Advice to doctor - Treat symptomatically. If necessary apply artificial respiration and administer atropine sulphate at 5-10 minute intervals until dryness of mouth occurs. This will relieve mucalinic manifestations. Atropine should not be given to a cyanosed patient. In cases of severe poisoning with respiratory depression or muscle twitching administer pralidoxime preferably less than 48 hours after exposure to relive nicotinic effects.
Contraindications - Never give patient morphine, theophylline or theophylline-ethylenediamine. Large amounts of intravenous fluids are generally contraindicated because of the threat of pulmonary oedema.
