In microbial remediation, work areas are typically _____ pressurized compared to surrounding unaffected areas.

In microbial remediation, work areas are typically maintained at negative pressure relative to surrounding unaffected areas. This practice is essential for controlling the spread of contaminants, particularly in situations involving mold or other hazardous microorganisms. By establishing a negative pressure environment, airborne spores and contaminants are drawn into the work area instead of being able to escape into adjacent spaces.

This method ensures that the affected environment is contained, which helps protect the health of both remediation workers and occupants in nearby areas. It also minimizes potential cross-contamination, allowing for a more controlled and effective remediation process. The concept of negative pressure is fundamental to microbial remediation protocols, as it supports safety and effective containment of harmful agents during the cleaning and removal processes.
