Toxicity	A potent lacrimator which is chemically stable and retains its irritancy in water and so can be used in liquid jets in personnel control. In addition to lacrimation, it causes eye pain, blepharospasm, eyelid swelling, irritation of the conjunctiva, a rise in intraocular pressure, and erythema of the skin. Because it can be used in water, its use is less affected by changes in climatic conditions. It is a more potent lacrimator than CS but it is less potent in lethality than CS.
