Which of the following is a characteristic of 'Active Containment'?

Active containment systems are designed to respond dynamically to the presence of a hazardous material, such as a spill, requiring human intervention to be effectively deployed. This means that personnel must actively engage the system, whether through the activation of equipment or making decisions based on the situation. This characteristic distinguishes active containment from passive systems, which are designed to contain spills or leaks without the need for immediate human action, relying instead on built-in features that respond to incidents automatically.

In contrast, options suggesting independent operation without monitoring, reliance on absorbent materials, or a comparison of efficiency with passive systems do not align with the nature of active containment. Such systems are specifically formulated to necessitate a proactive response, ensuring that containment measures are undertaken in real time to mitigate hazards effectively. This understanding of active containment is vital in contexts like spill response, emergency management, and environmental protection, where the ability to act swiftly is critical.
