Abstract
A trough surrounding the base of a machine for trapping the spilled chemical and draining it into a pit in which a pump is located that is automatically engaged to pump the spilled chemical into a closed holding tank. A vapor detecting device will, upon the detection of toxic vapors, automatically turn on a ventilation system that will remove vapors from the area of the trough and from an optional isolation tent surrounding the machine and force the vapors through a filter having a bed of charcoal for absorbing the toxic vapors from the air. The filtered air is then vented to the atmosphere. A splash curtain is also used to direct the spilled chemicals into the trough. A substantial portion of the apparatus may be molded as a single unit or as separate sections that may be readily assembled and fixed into a unit at the installation site.
