24 TOXICITY:

Summary:

Solvents and other formulating agents are likely to be more hazardous than the active ingredient.

Details:

Poison schedule - S6

Mammalian toxicity - Medium

Acute oral LD50 - 1369-2077 mg/kg (rats), [For comparison table salt is 3000 mg/kg]

Acute dermal LD50 - >2000 mg/kg (rabbit).

Skin - Non irritant but solvents can be irritating. Repeated or prolonged contact may cause dermatitis.

Eye - Non irritant but solvents can be irritating.

Vapour inhalation - LC50 - 4.8 mg/L air (rat).

Chronic oral toxicity NOEL - mg/kg for two years.

Not carcinogenic, mutagenic or teratogenic (i.e. does not cause cancer or reproductive problems).

Acceptable Daily Intake (ADI) - 0.1 mg/kg/day

Liver enlargement and elevated cholesterol levels have been seen in animals fed large prolonged doses.

Other Species -

Birds - toxicity. Oral LD50 >2510 mg/kg. Dietary LD50 >5620 mg/kg feed.

Fish - toxicity LC50 - 19-34 mg/L.

Invertebrates - toxicity LC50 - 5.2 mg/L (Daphnia).

Bees - toxicity.

25 TOXICITY SYMPTOMS:

Swallowing can cause nausea, vomiting and central nervous system depression (drunkenness). Breathing vomit may lead to aspiration pneumonia.

On skin it may cause degreasing and dermatitis.

Inhalation may cause dizziness, headache and nausea. High concentrations may cause central nervous system depression, lack of coordination and judgement and eventual unconsciousness.

26 FIRST AID:

If SWALLOWED - Rinse mouth with water. Do NOT induce vomiting. Give a glass of water. Seek medical advice. May cause lung damage if swallowed.

If in EYES - Irrigate with plenty of water.

If on SKIN - Rinse with plenty of water, remove contaminated clothing, wash with soap and water. If irritation occurs then see a doctor.

If INHALED - Remove patient to fresh air and rest until fully recovered. If patient has difficulty breathing or develops a bluish colour of the skin (cyanosis) give oxygen and take to a hospital quickly. Apply artificial respiration if patient stops breathing. See a doctor.

Advice to doctor - Treat symptomatically.
