Today's building codes frequently require safety measures such as:

Built-in sprinkler systems are a standard safety measure required by many building codes to enhance fire protection. These systems are designed to automatically detect and suppress fires, significantly reducing the intensity and spread of flames and smoke. They can effectively control or extinguish a fire before it has a chance to spread to other parts of the building, thereby protecting both occupants and property.

The adoption of built-in sprinkler systems is informed by evidence showing that they greatly enhance safety outcomes during fire incidents. They serve to minimize the risks associated with fire emergencies, allowing for safer evacuation routes and reducing the burden on fire services during interventions. Most modern building codes incorporate these systems because they align with life safety objectives and help to meet insurance safety regulations.

In contrast, while entry doors that open inward and stairwell doors that lock when alarms sound are relevant to building safety, they do not provide the same level of direct fire suppression or control as sprinkler systems. Water buckets are outdated safety measures and do not meet current standards for fire safety infrastructure in buildings.
