Which of the following is a type of containment used in construction?

The identification of active containment as a type of containment used in construction stems from its focus on preventing the spread of contaminants and managing hazards in an ongoing, dynamic manner. Active containment systems involve the use of barriers, diversion techniques, and other interventions that can respond to changing conditions in the construction environment, thereby ensuring the safety of workers and the surrounding areas.

This approach contrasts with passive methods that may simply involve physical barriers without the capability or interventions to adapt to or manage spills or hazardous situations dynamically. Active containment is crucial, especially in environments where hazardous materials may be present, as it enhances the overall effectiveness of safety protocols and present a more robust response to potential risks.

When evaluating other types of containment, temporary containment often refers to short-term measures set up for a specific project phase and may not encompass the proactive management aspect of active containment. Restrictive and adaptive do not align directly with commonly recognized types of containment in the construction industry. Restrictive suggests limitations rather than a proactive system, and adaptive does not typically define the standard containment practices in such scenarios. Hence, the focus on active strategies provides the most relevant and effective method of containment in construction settings.
