Balancing Reliability, Security, and Egress in Door Hardware Standards

Every door opening serves two fundamental purposes: it allows people in, and it allows people out. At first glance, that seems simple. In practice, these two goals (ingress and egress) are often in tension. A secure opening is designed to keep unauthorized individuals out, while a safe opening must always allow occupants to exit quickly and easily. When it matters most, particularly in an emergency, egress must take priority. 

At the heart of this balance is reliability. A lock function defined on paper has little value if the hardware does not perform in the field. Latches must retract. Doors must open under pressure and exit devices must function after years of wear. This is where BHMA standards play a critical role, establishing performance benchmarks for durability, strength, and operational consistency. Reliability is not simply a product feature; it is a life safety requirement.

One of the ways BHMA standards bring clarity to door hardware is through function numbers, as defined in ANSI/BHMA A156.2. These function numbers create a common language across the industry, precisely defining how a lock operates. They answer key questions: who can enter, who can exit, and under what conditions. While they may appear technical, their purpose is straightforward. Every function ultimately answers a single, essential question: what happens when someone tries to leave? This question becomes more complex when considering the competing priorities of security and life safety. On one hand, buildings must protect occupants from unauthorized access (this concern has grown in recent years, particularly in schools, healthcare facilities, and public spaces). On the other hand, life safety demands immediate and intuitive egress in the event of a fire, emergency, or other threats. These priorities can appear to conflict, for example, in lockdown scenarios, but standards are designed to ensure that security measures never compromise safe exit.

The principles behind these standards are not new. Many lock functions have been codified for decades, with roots going back to the 1970s and earlier. They are grounded in both mechanical logic and predictable human behavior. However, while the fundamentals remain stable, the environments in which they are applied continue to evolve.

Understanding how hardware should perform is only part of the equation. Standards define performance but building and fire codes determine where and when specific hardware must be used. Codes address factors such as occupancy load, the number and arrangement of exits, and the capacity of exit doors. Together, standards and codes create a comprehensive system. However, this system only works when standards are properly referenced and codes are consistently enforced.

Today’s built environment is introducing new pressures that require ongoing attention. Electronic access control systems are becoming more common, adding flexibility but also complexity. These technologies must integrate with mechanical hardware without compromising the fundamental requirement of safe exit. As systems become more interconnected, the need for clarity and consistency in standards becomes even more important.

This is why continuous evaluation and education are essential. Even the most well-developed standards can fall short if they are misunderstood, misapplied, or poorly maintained. Specifiers, installers, and building owners all play a role in ensuring that openings function as intended. Ongoing training and awareness help bridge the gap between design and real-world performance.

The role of BHMA will continue to expand as new technologies emerge and safety expectations evolve; standards must adapt to address changing conditions. At the same time, alignment with codes and increased industry education will remain critical to ensure that these standards are effectively implemented.

Door hardware is often overlooked until the moment it is needed most. In that moment, there is no time for confusion or failure. The true measure of any standard is not how it reads on paper, but how it performs in real life. When properly designed, specified, and maintained, door hardware quietly fulfills its most important role: helping people move safely through the built environment, every time.
