Key Engineering Controls and Work Practices

  • Develop a suitable mold remediation plan.  If abatement procedures are expected to generate a lot of dust (e.g., abrasive cleaning of contaminated surfaces, demolition of plaster walls) or the visible concentration of mold is heavy (i.e., blanket versus patchy coverage) follow the extensive contamination procedures below
  • Consult with industrial hygienists or other environmental health and safety professionals with experience performing microbial investigations and/or mold remediation before beginning remediation
  • The work area and areas directly adjacent to it should be unoccupied
  • Cover surfaces in the work area and adjacent areas that could become contaminated with secured plastic sheets to contain dust and debris and prevent further contamination
  • Seal ventilation ducts/grills in the work area and areas directly adjacent with plastic sheeting
  • Use dust suppression methods (e.g., misting (not soaking) surfaces prior to remediation)
  • Clean and/or remove materials as noted in the damage materials page.  Seal materials being removed in plastic bags
  • The work and surrounding areas should be HEPA vacuumed and cleaned with a damp cloth or mop and a detergent solution
  • All areas should be left dry and free from contamination and debris
