Arkansas Boiler Operator Practice Exam

What characteristic is not true about high-pressure boilers?

1. They must be monitored constantly

2. They contain fitting appliances

3. They require stringent safety standards

4. They operate above 15 psi

The correct answer is: They contain fitting appliances

The assertion that high-pressure boilers contain fitting appliances is not characteristic of high-pressure boilers as typically defined in operational contexts. While it is common for boilers to be equipped with various fittings and appliances necessary for their operation, this statement does not inherently describe the nature of high-pressure boilers specifically. High-pressure boilers are primarily characterized by their operating pressure, which is above 15 psi, requiring stringent safety standards due to the risks associated with higher pressures. This includes constant monitoring to ensure safe operation—both of which are crucial aspects of high-pressure boiler management. The inclusion of fittings and appliances varies between different types of boilers and is not a defining characteristic of high-pressure classifications.
