Which term describes the isolation of an exposure from other exposures, hazards, or perils to reduce severity?

• A. Risk Segregation
• B. Risk Separation
• C. Risk Duplication
• D. Risk Transfer

Answer: (A)

Isolating an exposure from other exposures to reduce severity is described as risk segregation. The idea is to deliberately keep hazards apart so that a problem in one area cannot easily interact with others, which limits how bad an incident can become. This is achieved through controls like barriers, distance, zoning, or dedicated equipment that physically or functionally separates hazards.

This differs from transferring risk, which moves potential losses to another party (like insurance) rather than reducing the hazard's potential impact itself. It also differs from the less-specific idea of separation and from duplication, which would not achieve the goal of reducing severity and can even amplify risk.
