Apparently, it's a painful process. If a liquid drips on you, you are supposed to immediately get in a safety shower for 15 minutes unless the liquid is determined to be water before time's up. Oh, and the safety shower water isn't heated. It's room temperature, at first, then it gets really cold.
not the first time I've heard that the safety shower needs to be cold, rather than warm. A local farmer died about 20yr ago when he accidentally splashed concentrated roundup on him self. He raced inside and jumped under the warm shower. According to what we were told, the warm water opened his pores, and allowed more of the poison into his system. Had he had a cold shower, less of the poison would have been absorbed, and he may have survived. The advice above, in a much more official memo was posted at all out local farm supply places as a result of his death as a warning to everyone buying and using roundup concentrate.
