Safety procedures for mold contamination investigators. Here we cite the importance of using good safety procedures when looking for mold or when cleaning up mold in buildings and we provide links to mold inspection, testing, and remediation guidelines. To assure that a mold cleanup has been properly performed, see MOLD CLEARANCE INSPECTIONS.

Mold Safety Warnings for Do-It-Yourself'ers

Three Serious Mold Inspection or Cleanup Mistakes

There are the most common and most serious mistakes that we encounter when reviewing mold inspection and mold cleanup or "remediation" jobs.

Failure to protect the inspector, worker or occupants from toxic or allergenic mold that may be disturbed and brought to elevated levels in the building during inspection and testing.

These errors include failure to wear proper protective equipment during inspection and remediation work, and failure to establish and maintain adequate dust control measures during a mold remediation project.

The second example often results in an extended and unnecessarily costly mold cleanup job, while the first example can lead to temporary or even more serious illness of the inspector or occupants.
Failure to find and remove the problem mold in a building. Too often, incomplete inspection, incompetent testing, or hasty "magic bullet" approaches to mold remediation result in incomplete work, and often they even result in removing materials that were not the mold problem while leaving the problem mold in place.

We have reviewed too many projects for which the building owners have paid a high fee for work that did little or nothing to remove the mold problem.
Mold Cleanup Project Containment Failures: perhaps the most common mold remediation project failure after failing to properly and thoroughly inspect and diagnose the locations and causes of mold reservoirs prior to starting work, is failure to properly control dust and debris caused by demolition and removal of moldy materials such as carpeting, drywall, or plaster.
Reliance on shortcuts for mold inspection, mold testing, and mold remediation.

Examples are sole reliance on infra-red inspection or mold sniffing dogs or air tests to find mold in buildings, inadequate dryout methods after flooding in buildings, and use of bleach or fungicides as a substitute for actual cleaning or removal of problem mold.

Such measures are ineffective and in some cases, they can be dangerous for building occupants.

Mold Cleanup Safety Procedures & Remediation Procedures

Guidelines defining what's a "large amount" of mold and what's reasonable for a homeowner to handle have been published by several states including New York and California.

Links to key documents describing mold cleanup and mold remediation procedures are at ACTION GUIDE - WHAT TO DO ABOUT INDOOR MOLD

People who are allergic, asthmatic, infant, elderly, immune-impaired, etc., should not disturb mold and should not be in the area where mold remediation is being performed. Consult with your doctor, health department or other professional before tackling this job yourself.

OTHER IAQ ISSUES: How To Find and Address Other Indoor Air or Indoor Environment Contaminants Besides Mold

Mold or allergens may not be the only or even the main indoor environmental contaminant. Don't let media attention to mold cause so much enviro-scare fear that other, possibly more urgent hazards go un-addressed.

Sewage and Septic backup contamination in buildings: inspection, testing, remediation, & references to expert sources
Other environmental risks: Asbestos, carbon monoxide, electromagnetic fields, environmental illness, fiberglass, MCS - multiple chemical sensitivity, toxic gases, etc
Indoor Gas Sampling Plan for Residential Buildings lists a number of toxic indoor gases which we test for, depending on the building complaint and building conditions
Ozone Warnings - Use of Ozone as a "mold" remedy is ineffective and may be dangerous.
Pet control - if you can't say goodbye to your bird, cat, dog, guinea pig, hamster, tropical fish, then limit the areas they occupy and limit the airflow from that area to sleeping or other areas of the building, use allergenic bedding, eliminate wall-to-wall carpeting, improve housecleaning including use of a HEPA-rated vacuum cleaner. For more details see our article Dog, Cat, and Other Animal Dander - Information for Asthmatics and Indoor Air Quality
Rodents, Mice, Squirrel Control - I find high levels of mouse and rodent dander, fecal dust, and urine-contaminated dust in some buildings, and high levels of these materials in building insulation in those locations. If you have a mouse problem, particularly if mice and their waste (fecals or urine) are contaminating the building HVAC or building insulation, may need both steps to clean up or remove infected materials and steps to stop an ongoing rodent problem. If squirrels are a problem, the cleanup needs to include closing off entry openings into the building. Get some help from a licensed pest control expert.
