Mold Remediation

FACT SHEET 9580.100

Overview

Extensive disaster-related damages may result in public facilities becoming inundated or exposed to wet and humid weather conditions for extended periods of time. The limited availability of repair and restoration contractors may delay clean-up activities. In addition, the disruption of electrical power can inhibit the use of water extraction, pumping and drying electric equipment. As such, the damaged structures and their contents may remain waterlogged until power is restored and remediation can begin. Such water saturation may cause growth and propagation of mold on structures and interior contents, causing health-related problems and increasing the cost of repairs. The following guidance is provided to assist Public Assistance staff and applicants (entities that meet the requirements of 44 CFR 206.222 - State, local governments, Indian tribes or authorized tribal organizations, and certain private non-profits) with the remediation and/or repair of their damaged facilities.

Sizing the Scope of Work

The extent of contamination will dictate the containment and personal protection equipment used by the Applicant or contractor during remediation work. The following parameters may be used as a general guideline.
*Size designation *Personal Protective Equipment *Containment Remediator
Small (<10 sf) Minimum RN-95 respirator
Gloves
Goggles
None required Force Account
Medium (10 - 100 sf) Limited or Full OSHA requirements Limited, containment of the contaminated area using sheeting Force Account or Remediation Contractor depending on contaminated materials
Large (>100 sf) Full OSHA requirements Full containment Remediation Contractor

Mold Remediation Methods

Method Application
Wet Vacuum
  • Use when materials are wet
  • Use where water has accumulated, such as on floors, carpets and hard surfaces
  • Do not use when sufficient liquid is not present
Damp Wipe
  • Wipe or scrub non-porous (hard) surfaces with water and detergent
  • Follow instructions listed on the product label
High Efficiency Particulate (HEPA) Vacuum
  • Final clean-up after thoroughly dry, and contaminated materials are removed
  • Recommended for cleanup of dust outside of the remediation area
  • Properly seal HEPA filter
  • Personal protection equipment (PPE) is highly recommended; filter and contents must be disposed of in well-sealed bags
Discard
  • Building materials and furnishings that cannot be remediated
  • Seal contents in two bags using 6-mil polyethylene sheeting
  • Large items may be covered in polyethylene sheeting and sealed with duct tape
  • Sealing materials must be within containment area to limit further contamination

  • Scrubbing may be necessary
  • Allow to dry
Upholstered furniture
  • Wet vacuum
  • Accelerate drying process with dehumidifiers, fans and/or heaters
Wallboard (dry wall and gypsum board)

  • Ventilate wall cavity
Window drapes
  • Launder or clean according to manufacturer's instructions
Wood surfaces
  • Remove water with wet vacuum
  • Accelerate drying process with dehumidifiers, fans and/or heaters
  • Treated or finished wood, damp wipe
