True or False: Under Texas code, unfired boilers are required to have regular internal inspections.

Unfired boilers indeed require regular internal inspections as mandated by Texas code. An unfired boiler, which typically includes equipment like heat exchangers or other devices that use pressurized fluids but do not generate steam, must adhere to safety standards that ensure their operational integrity and safety. Regular internal inspections are critical for identifying potential issues such as corrosion, wear, and accumulation of deposits, which could lead to failure or unsafe conditions if left unchecked.

The necessity for these inspections stems from the need to protect public safety and maintain compliance with regulations set forth by the Texas Boiler Law. These inspections help ensure that unfired boilers remain in good working condition, thus minimizing risks associated with leaks or other mechanical failures.

In contrast, other options that suggest inspections may be conditional, like only in certain circumstances or based on the age of the boiler, do not align with the requirement of routine safety checks established under Texas law. This underscores the importance of regular maintenance and oversight of all unfired boilers regardless of their specific circumstances or age.
