Demystifying Mold - Part II
Remediation
Remediation Planning
The first step in remediation planning is to assess the size of the moisture problem and the type of damaged materials before beginning any remediation work. Medium and large size projects should have a written plan in place before work commences. The written plan should include the steps to fix the water or moisture problem. The plan should outline the use of appropriate Personal Protective Equipment (PPE) and include steps to contain and remove the affected building materials to avoid the spreading of the mold. The remediation plan will vary depending on the size and complexity of the job, and may require revisions if circumstances change and when new facts are discovered.
The following questions should be considered prior to remediation:
• Are there ongoing moisture problems in the building?
• Are there hidden sources of water or moisture?
• Have the building materials been wet for more then 48 hours?
• Does the building smell musty or moldy?
• Are building occupants reporting heath problems?
• Has the building been recently remodeled or has the building use changed?
What is Mold Remediation?
Remediation is the physical removal, collection, and containment of mold growth and mold spores from the air, surfaces, and materials. Remediation should always address the underlying problem(s), such as moisture accumulation or water damage, that led to mold growth in the first place.
Remediation is intended to reduce the likelihood of exposure, correct the deficiencies that caused mold growth, and restore the area to an acceptable condition consistent with the needs and susceptibility of the occupants.
When to Remediate
Remediation is appropriate when the mold growth presents an unacceptable risk to human health and comfort. There are no standards or guidelines for remediation. The level of risk and remedial action depend on many factors, some of which are controllable and some not. The following bulleted items are "no brainers" for when remediation is necessary:
• Where there is water damage and/or visible mold growth.
• Where there is confirmed medical diagnosis of a fungi-related disease.
• Where there is a clear link between negative health effects and extensive visible growth indoors.
