According to EPA guidance, what containment type is required for 10 to 100 sq feet?

In the context of mold remediation, the Environmental Protection Agency (EPA) outlines specific containment requirements based on the size of the area affected by mold. For areas measuring between 10 to 100 square feet, the guidelines recommend "minimum containment." This type of containment is designed to limit the spread of mold spores and other contaminants while still allowing for the necessary accessibility to perform remediation work effectively.

Minimum containment typically involves sealing the affected area with plastic sheeting and using equipment to mitigate dust and spore dispersal, such as negative air machines. The objective is to create a controlled environment that prevents cross-contamination while also ensuring the safety of the workers handling the remediation process.

Understanding the correct type of containment is crucial because using an inappropriate level of containment could either underestimate the risk, allowing mold spores to escape and affect other areas, or overestimate the situation, leading to unnecessary complexity and cost in the remediation process.
