If damaged TSI cannot be repaired, what is the required action?

• A. It must be enclosed
• B. It can be encapsulated
• C. It should be left as is
• D. It must be removed

Answer: (D)

When a device is damaged and cannot be repaired, the safe and correct action is to remove it from service. Keeping or attempting to fix it in place isn’t enough because the fault could still cause unsafe conditions, faulty readings, or exposure to hazardous substances. Enclosing or encapsulating the damaged unit might hide the problem but does not restore safe operation or data integrity, so it’s not an acceptable remedy. Leaving it as is leaves a known risk in the work area and could lead to accidents or unreliable monitoring results. Removing the damaged TSI ensures the equipment isn’t used until it’s properly repaired or replaced, protecting workers and maintaining data quality.
