The primary purpose of the first safety valve on a boiler is to prevent the boiler from exceeding its maximum allowed working pressure. This safety feature is crucial in protecting the integrity of the boiler and ensuring safe operation.

When the steam pressure inside the boiler rises beyond the designed safety limits, the safety valve automatically opens to release excess steam, thus preventing dangerous overpressure situations that could lead to catastrophic failures, explosions, or damage to the boiler system. This function is critical for maintaining safe operating conditions and complying with regulatory standards, which dictate that a boiler must have at least one safety valve to safeguard against excessive pressure.

The other options involve important functions related to boiler operation, but they do not pertain to the specific role of the first safety valve. Maintaining water level, regulating steam flow, and increasing pressure all refer to different components or functions within a boiler system, but they do not fulfill the essential safety purpose of the safety valve, which is fundamentally about pressure control.
