Mold Remediation Certification Practice Exam

What pressure range is typically used for low pressure flushing during remediation?

1. 10 - 30 psi

2. 20 - 60 psi

3. 30 - 50 psi

4. 40 - 80 psi

The correct answer is: 20 - 60 psi

The pressure range of 20 to 60 psi is considered optimal for low pressure flushing during mold remediation. This range is effective because it is strong enough to dislodge contaminants and mold spores while remaining gentle enough to avoid causing damage to the surfaces being cleaned. Flushing at this pressure helps to minimize the risk of disturbing settled spores and prevents further spread of mold. Using pressures below 20 psi may not sufficiently remove debris, while exceeding 60 psi could lead to excess water intrusion or damage to material surfaces, thereby complicating the remediation process. Therefore, the 20 to 60 psi range strikes a balance between effective cleaning and preserving the integrity of the materials being treated.
