Arkansas Boiler Operator Practice Exam

A high-pressure boiler operates at what pressure level?

1. Above 5 PSI

2. Above 10 PSI

3. Above 15 PSI

4. Above 20 PSI

The correct answer is: Above 15 PSI

A high-pressure boiler is defined by operating at a pressure level above 15 PSI. This classification is crucial because it determines the safety regulations and licensing requirements that must be adhered to by operators. Boilers classified as high-pressure typically involve more complex safety considerations, maintenance, and operational practices compared to low-pressure boilers, which operate at 15 PSI or below. Therefore, recognizing that 15 PSI is the threshold establishes the correct understanding of what constitutes a high-pressure boiler within the context of boiler operation standards. Understanding this classification is essential for safe and effective boiler management in various industrial and commercial settings.
