4. objects being removed must be cleaned/remediated prior to removal
5. the containment is to be ventilated with HEPA ventilation unit exhausted outside the
building
✔✔What containment is recommended for removal of mold by the EPA for greater than
100sf? - ✔✔Full
1. double layers of fire retardant 6 mil poly

PPE, all contaminated PPE should be placed in sealed bag in this chamber, excluding
respirators
5. respirators should be worn until outside decon chamber.
