What approach is used to change the probability of failure?

Reinforcing a facility structure is an effective approach to change the probability of failure because it directly strengthens the integrity of the building or system. This process involves assessing potential weak points and enhancing materials or designs to withstand stresses, environmental factors, or operational loads. By increasing the resilience of the structure, the likelihood of structural failure due to various stressors is reduced, leading to a more robust and reliable facility.

In contrast, demolishing old structures may eliminate risks associated with outdated designs, but it does not address current structures' vulnerabilities. Increasing training for staff could improve operational safety and maintenance practices, but it does not directly alter the structural integrity of the facility itself. Implementing stricter regulations can ensure that future designs adhere to higher standards, but without direct reinforcement of existing structures, it does not affect their current state.
