Excessive mold growth in indoor environments has become an increasing health and environmental concern as well as the subject of controversy and litigation. While human response to mold varies widely, no official exposure/response relationship exists. Neither are there currently any definitive clearance criteria or legislative guidelines for mold remediation, although a number of de facto standards are generally accepted. Work practices such as

(1) Containment and use of negative pressure for dust (spore) control.

(2) Three-stage decontamination procedures.

(3) Use of HEPA-filtered equipment.

(4) Personal protection such as respirators and protective suits are very similar to those for asbestos abatement work.

However, there are important differences that should be considered when selecting an environmental contractor to perform mold or microbial remediation services. We will begin by looking at the nature of mold infestations and then discuss existing guidelines and recommended work practices. Most important, we will look closely at how a mold remediation project differs from an asbestos abatement project, including the health and safety training requirements for workers and important contractor insurance coverage that should not be overlooked.
