How does a person accidentally douse themselves twice in Roundup (weed killer)?

Panhandler of the century should be laughed out of court.

If it is being used on a farm with big machines and pump pressurised pipes then failure of a pipe or a pipe connector could happen as can wind blowing the spray back on the operator.

Obviously any chemical spraying should only be carried in in calm conditions and using equipment that is regularly checked and serviced, but some people ignore such obvious directions.
