Resisting boiling pressure in low-pressure steam boilers can lead to significant safety risks. When a boiler is designed to operate at low pressure, it relies on specific pressure regulations to ensure safe and efficient operation. If the boiling pressure is not adequately maintained and the pressure within the boiler system becomes too high or unstable, it can cause failure in critical safety devices or even lead to a catastrophic boiler explosion.

Levels of pressure exceeding the design specifications can overwhelm safety valves designed to relieve excess pressure, causing them to fail. Additionally, materials used in these boilers may not withstand excessive pressure, leading to structural failures or leaks that could pose hazards to operators and surrounding areas. Thus, managing boiling pressure within designed limits is essential for maintaining both safety and operational integrity in low-pressure steam boiler systems.
