In extreme mold remediation circumstances , Grimefighers will provide containment to prevent contamination outside the work area.  The intent of the containment is to isolate the indoor areas that are subject to contamination from the remediation activities.  The containment area is as small as possible to efficiently conduct a proper remediation.  When possible, ingress and egress of the containment area is to the outdoors.  When not possible to have ingress and egress to the outdoors, a decontamination chamber is installed.

All movable items within the proposed containment area are cleaned and removed prior to building the containment.  Items that remain in the proposed containment area including cabinets, carpet or other floor finishes, plumbing fixtures, or other non-moveable items are cleaned, sealed, and covered in plastic sheeting prior to building the containment.  Items in the containment remain sealed for the duration of the remediation activities.  After the remediation activities are completed, but prior to any clearance sampling, the containment and all items in the containment are cleaned by wet wiping and/or HEPA vacuuming.
