?? Sensitization: No sensitizing effects known.

?? Subacute to chronic toxicity:

Organic phosphorus compounds exhibit a wide range of toxicity.
Most are skin and eye irritants with the more volatile also
being respiratory irritants. Those exhibiting substantial
water reactivity will have stronger irritating properties and
may be corrosive enough to cause severe burns. Some organic
phosphorus compounds are cholinesterase inhibitors. Symptoms
associated with these include muscle twitching, convulsions,
