How Much Mold Are You Dealing With and How are You Trying To Treat It?

If you are trying to research how to remove a small amount of mold, please try here:  How to Remove Mold, Level 1

The goal of a remediation or mold removal project is to remove or clean mold­ damaged materials using work practices that protect occupants by controlling the spreading of microbial from the work area and protect remediation workers from exposures to mold.
This article is for reference and research only and all work completed should be done by a licensed and certified mold remediation contractor. Before starting a mold removal job, the structure should be properly inspected for other hazardous materials such as lead and asbestos.

When completing a mold removal project, the underlying cause, such as the cause of the dampness and moisture must be resolved prior to the built back or repair. For large areas greater than 100 square feet, properly trained and equipped mold remediation technicians should complete the mold removal. Having an Indoor Air Quality Professional oversee the project is also helpful to maintain compliance. All OSHA Regulations for Mold Remediation should be strictly be followed.

When large­scale remediation is performed, the manager of the building should notify all occupants. Notification should include a description of the remedial measures to be taken and a timetable for completion. Signs should also be posted to warn of areas that are off limits. Proper equipment will be required for the mold removal see: Equipment Required for Mold Removal.

Proper Personal Protective Equipment should be worn when completing the remediation inside of the containment. This includes a mold approved face mask, fully body mold removal suit, glove and eye protection. Before the demolition is to begin, a Mold Containment will need to be in place. See How To Enter and Exit a Mold Containment Properly With Proper Protective Equipment.

A mold containment with 6 mil clear plastic should be set up to contain the work area. See How to Build a Mold Containment.  The HVAC system within the work area should be shut down and all vents should be covered with plastic sheeting and sealed with duct tape. The containment should be put under negative pressure using a HEPA filtration device. Egress to the containment should be covered with plastic sheeting.

Any pourous contents affected by the mold should be discarded and thrown away. See How to
Remove and Throw Away Moldy Contents.   To Demolish and Remove Mold Affected Materials Limiting dust is encouraged by cleaning gently, misting surfaces with antimicrobial cleaning agents, and using high powered HEPA vacuums. After the contaminated materials have been removed from their original place, they should be disposed of in 3 mil trash bags. See How to Properly Dispose of Mold.  After demolition, a Final Detailed Cleaning Before Removing a Mold Containment should be completed. This involves HEPA vacuuming, cleaning
the area with a damp cloth, and HEPA vacuuming again for zero debris allowance.

Before leaving the mold containment, technicians should dispose of the mold suits and clean equipment. All plastic sheeting and disposable items should be discarded. The work area should be left dry and dust free. If required, the cleaning of HVAC system should also be completed.
