DOI: 10.1177/1420326X04044208 Final Clearance Criteria After Mould RemediationADS Consulting, Las Vegas, USA
Envirosafe Training and Consultants, Pittsburgh, USA john.pam.lange{at}worldnet.att.net Final clearance sampling practices for mould abatement projects have not been evaluated. This paper proposes procedures to remedy this. It is suggested that following remediation and after the visual inspection at least five to seven air samples should be collected. These sampling practices can also be used to screen for mould problems as part of a visual inspection and to assist in recognizing a problem dwelling. It is suggested that screening should involve taking at least four samples. To determine if the air concentration of mould is elevated it is necessary to sample inside and outside the building (abatement area). Since these samples have been shown to be non-normal in distribution, transformation is required or non-parametric statistic testing must be performed to determine whether the airborne mould concentration is elevated inside the area of interest (the building).
