Question 5: During a risk assessment of a chemical manufacturing facility, how would you quantify the potential impact of a failure in a critical component such as a pump?

Which action should you take?

Choose only one option

Checking the brand and specifications of the pump

Using a combination of failure modes and effect analysis (FMEA) and reliability modeling

Estimating the cost of replacement for the pump

Question 6: How does data from predictive maintenance sensors impact decision-making for equipment replacement in a petrochemical facility?

Which action should you take?

Choose only one option

It reduces the need for any further maintenance

It helps predict failure time and optimize the replacement schedule

It forces immediate replacement of all components regardless of condition

It only provides data about current performance without forecasting failure
