Mold Remediation Certification Practice Exam

What is the pressure range for low pressure spraying used in mold remediation?

1. 0 - 20 psi

2. 20 - 60 psi

3. 60 - 100 psi

4. 100 - 150 psi

The correct answer is: 20 - 60 psi

The range of 20 to 60 psi is considered optimal for low-pressure spraying in mold remediation because it provides sufficient force to effectively apply mold removal agents without causing overspray or atomization that high pressures might create. This controlled pressure minimizes the risk of dispersing spores into the air, which can occur at higher pressures, thus enhancing safety and efficacy during the remediation process. Additionally, low-pressure spraying allows for better saturation of the surface being treated, ensuring that the mold remediation solution penetrates effectively into any porous materials, which is essential for achieving desirable results. Maintaining this pressure range supports both thorough application and the safety of the environment where remediation is performed.
