22. TOXICITY:

Poison schedule - S7
Mammalian toxicity - Highly toxic.
Acute oral LD50 - 29 mg/kg
Acute dermal LD50 - mg/kg
Vapour inhalation - LD50 mg/L
Skin - Mildly irritating.
Eye - Mildly irritating
Main exposure routes - Handling concentrate. Air blast application.

Summary:
Details:
Poison schedule - S7

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

23. TOXICITY SYMPTOMS:

Initial symptoms include headache, nausea, lack of appetite and fatigue during exposure or several hours later. Dizziness, vomiting, stomach pains, contracted pupils, muscle weakness, twitching, tremor, slow heart beat, blurred vision and sweating may occur with higher exposure levels.
Continual low level exposure may cause influenza like symptoms.

24. FIRST AID:

Contact a doctor or poison information centre on 008 119 244.
Give atropine (0.6mg) tablets every quarter hour then every half hour until signs of flushed face, dilated pupils, dry mouth and fast pulse appear. Medical attention must be sought after taking atropine.
Remove contaminated clothing and wash skin.
If breathing has stopped apply resuscitation
Poisoning usually occurs through skin absorption. Effects are cumulative and dangerous levels may develop before symptoms become noticeable. If you are exposed to organophosphate for more than 30 hours per month then levels of acetylcholinesterase enzyme should be regularly checked. If levels drop below 60% of normal then work with organophosphates should stop until levels improve. This may take several weeks.
