Mold Remediation - Plan the Remediation Before Starting Work

Questions to Consider Before
Remediating

Are there existing moisture problems in the building?
Have building materials been wet more than 48 hours? (See Table 2 and text)
Are there hidden sources of water or is the humidity too high (high enough to cause condensation)?
Are building occupants reporting musty or moldy odors?
Are building occupants reporting health problems?
Are building materials or furnishings visibly damaged?
Has maintenance been delayed or the maintenance plan been altered?
Has the building been recently remodeled or has building use changed?
Is consultation with medical or health professionals indicated?

Mold Remediation Plan

Assess the size of the mold and/or moisture problem and the type of damaged materials before planning the remediation work. Select a remediation manager for medium or large jobs (or small jobs requiring more than one person). The remediation plan should include steps to fix the water or moisture problem, or the problem may reoccur. The plan should cover the use of appropriate Personal Protective Equipment (PPE) and include steps to carefully contain and remove moldy building materials to avoid spreading the mold.(2) A remediation plan may vary greatly depending on the size and complexity of the job, and may require revision if circumstances change or new facts are discovered.

The remediation manager's highest priority must be to protect the health and safety of the building occupants and remediators. It is also important to communicate with building occupants when mold problems are identified.(3) In some cases, especially those involving large areas of contamination, the remediation plan may include temporary relocation of some or all of the building occupants.

The decision to relocate occupants should consider the size and type of the area affected by mold growth, the type and extent of health effects reported by the occupants, the potential health risks that could be associated with debris, and the amount of disruption likely to be caused by remediation activities. If possible, remediation activities should be scheduled during off-hours when building occupants are less likely to be affected.

Remediators, particularly those with health-related concerns, may wish to check with their doctors or health care professionals before working on mold remediation or investigating potentially moldy areas. If you have any doubts or questions, you should consult a health professional before beginning a remediation project.
