Which term describes securing or isolating the root of the problem?

• A. Indirect attack
• B. Direct attack
• C. Fog attack
• D. Mechanical isolation

Answer: (D)

Securing or isolating the root of a problem means cutting off the source so the issue can’t continue or spread. This is accomplished through mechanical isolation—physically disconnecting or closing the path feeding the hazard. In practice, you’d shut valves, disconnect power or fuel, stop pumps, seal off lines, or close compartments to prevent the problem from worsening. This approach targets the origin of the damage rather than trying to attack or suppress it at a distance, which is what direct or indirect fire attacks and other techniques focus on.
