The correct choice for ensuring safety in the event that pressure becomes excessive is a pressure release valve. This type of valve is specifically designed to automatically open to release excess pressure from a system, preventing possible explosion or damage due to over-pressurization. Pressure release valves are crucial in maintaining safe operational conditions within systems that involve steam or other pressurized fluids.

In contrast, back pressure relief valves are utilized in specific scenarios to control pressure downstream in a system, but they do not function as a safety mechanism for excessive pressure build-up. Check valves are intended to prevent backflow in a system rather than to relieve pressure. Flow control valves serve to regulate the flow of fluid, but they do not address pressure issues directly.

Understanding these distinctions is vital for safe boiler operation as well as compliance with safety regulations in boiler management.
