Fire protection engineering is fundamentally about protecting lives and property from fire and its associated hazards.
While building codes have become indispensable tools for ensuring safety standards in the built environment, today’s widespread adoption has led engineers to be over-reliant on prescriptive requirements, which risks overshadowing core engineering principles.
This article argues that hazard identification must remain the foundation of fire protection design.
By using hazard identification and evaluation techniques that recognize unique risks, engineers can move beyond prescriptive compliance toward a fit-for-purpose solution that truly mitigates fire hazards.
Codes are necessary and rightly used in many applications, but they are not substitutes for engineering judgment.
This article explores the limitations of codes, the importance of hazard identification and strategies for integrating both to achieve robust fire safety.
Fire protection engineering exists to protect life and property from loss in the event of fire.
Over time and through many painful lessons, building codes have become essential tools providing standardized requirements that ensure a baseline level of safety.
However, reliance on prescriptive codes has led to an unintended consequence: the erosion of engineering judgment. Codes are not a substitute for critical thinking but rather the framework.
The foundation of effective fire protection begins with hazard identification.

Before applying any code, engineers must understand the unique risks inherent to a facility and its processes.
This is especially true in high-hazard environments such as chemical manufacturing, large-scale warehousing and emerging technologies.
The use of “occupancy,” which is designed to address “typical” conditions for a particular type of facility, fail to address atypical hazards that can lead to catastrophic outcomes.
A return to sound engineering principles – identify hazards, assess risk and then apply engineering solutions to mitigate those risks – is needed.
If the hazards fit the occupancy definition in the codes, then the code can be used as one of many tools to mitigate those risks.
By doing so, fire protection engineers can move beyond compliance and deliver true safety.
Building codes exist for good reason. They provide a standardized framework that ensures a baseline level of safety across typical occupancies.
Codes simplify enforcement, create consistency and offer guidance for design professionals and authorities having jurisdiction (AHJs).
For most buildings such as offices, schools, residential structures, prescriptive codes work well because hazards are predictable and well understood.
However, codes are not intended to replace engineering judgment. They are tools, not solutions.
Donald Meyer
Codes assume typical conditions and cannot anticipate every unique hazard.
When engineers treat codes as the final word rather than a starting point, they risk overlooking critical vulnerabilities.
The danger lies in designing for compliance rather than mitigating the actual hazards present.
True fire protection requires understanding the specific hazards of an occupancy and applying codes in context.
Prescriptive codes often fail in environments where hazards deviate from the norm.
High-hazard industries such as chemical manufacturing involve volatile substances and complex processes that exceed the assumptions embedded in standard codes.
Warehousing presents another challenge: the storage of hazardous materials can dramatically increase fire load and heat release rates; overwhelming sprinkler systems and passive protection measures designed for conventional layouts.
Emerging technologies can introduce new risks that are not typical since they may not have existed when a code was written.
Lithium-ion battery storage facilities, for example, pose hazards related to thermal runaway, a phenomenon not fully accounted for in traditional fire protection standard.
Donald Meyer
Similarly, energy storage systems and advanced manufacturing processes create scenarios where prescriptive requirements may fall short.
In these cases, hazard identification becomes critical. Without it, engineers risk designing systems that meet code but fail under real-world conditions.
Fire Hazard identification is the systematic process of recognizing potential fire risks that focus on key factors needed for a fire to occur (such as fuel, oxygen and ignition).
It is the foundation upon which all fire protection strategies should be built.
This step precedes code application because it informs the selection of appropriate measures, whether prescriptive or performance-based.
Hazard identification includes two key tasks: (1) identification of specific undesirable consequences and (2) identification of material, system, process and facility characteristics that could produce those consequences.
Once a hazard has been identified, a hazard evaluation can be completed to ensure adequate protection is in place to mitigate the consequences of a hazard.
Donald Meyer
This methodology allows engineers to anticipate what can go wrong, evaluate the severity and prioritize mitigation strategies to reduce or eliminate the hazard.
By starting with hazard identification, engineers ensure that design decisions address actual risks rather than assumed ones.
Codes should complement hazard analysis, not replace it.
It can be the first tool evaluated to mitigate the hazard. However, if the prescriptive requirements fall short, a fit-for-purpose design should be considered as a path forward.
This approach could use both qualitative and quantitative methods to achieve safety objectives tailored to the specific hazards.
Collaboration among engineers, AHJs and stakeholders is essential to balance compliance with innovation.
The goal is not to abandon codes, but to use them intelligently – as part of a broader strategy grounded in risk assessment and sound engineering judgment.
Donald Meyer
Building codes are essential tools, but they are not substitutes for engineering judgment.
Hazard identification must remain the first principle of fire protection design.
By starting with a clear understanding of risks and integrating codes into a broader strategy, engineers can move beyond compliance and deliver true safety.
So, let’s reclaim engineering judgment and put hazard identification first.
