Questions Asked in Fire Protection Drawings Interview
Q 1. Explain the difference between active and passive fire protection systems.
Active and passive fire protection systems work together to protect a building from fire. Think of it like a two-pronged approach to defense. Passive fire protection acts as the first line of defense, aiming to contain the fire and prevent its spread. This includes things you don’t have to actively operate, like fire-resistant walls, doors, and floor assemblies. These materials are designed to withstand high temperatures and prevent the passage of flames and smoke for a specified period.
Active fire protection systems, on the other hand, are actively involved in suppressing or extinguishing the fire once it starts. These are the systems that do something; they actively fight the fire. This includes things like sprinklers, fire alarms, and smoke detectors, which automatically detect and respond to a fire.
- Example of Passive System: A two-hour rated fire-rated wall, separating different areas of a building, slowing down the fire spread and providing time for evacuation.
- Example of Active System: A sprinkler system that automatically activates when a fire is detected, suppressing flames and reducing the spread of fire and smoke.
In essence, passive systems focus on containment and delay, while active systems focus on suppression and extinguishment.

- Drawing Coordination: I ensure that all relevant drawings are properly referenced and aligned, creating a consistent and unified set of documents.
This collaborative effort leads to a cohesive design and reduces the likelihood of conflicts during the construction phase, ensuring the seamless integration of fire protection systems within the overall building design.
Q 7. Describe your experience with fire modeling software.
While I haven’t personally used fire modeling software on every project, I understand its value and application. I’m familiar with several software packages used for computational fluid dynamics (CFD) modeling, which can simulate fire spread and smoke movement within a building. This data can inform the design of fire protection systems, optimizing their placement and ensuring effective fire suppression and occupant evacuation. I can interpret and utilize the results of such modeling to inform my design decisions and improve the overall fire safety design of the project.
For example, if a CFD model shows that smoke is likely to accumulate in a specific area of a building, this could influence the placement of smoke detectors or the design of the smoke evacuation system. While not directly involved in the modeling process in every project, my understanding of its output and implications allows me to collaborate effectively with fire modelers and incorporate their findings into the fire protection drawings.
Q 8. How do you handle conflicts or discrepancies between different fire protection drawings?
Resolving conflicts in fire protection drawings requires a methodical approach. Think of it like a detective investigation – you need to find the source of the discrepancy and determine the most accurate and code-compliant solution. I begin by carefully comparing all relevant drawings – architectural, structural, mechanical, and fire protection – to identify the conflicting information. This often involves cross-referencing plan numbers, details, and specifications. If the conflict is between two different fire protection drawings, for instance, one showing a sprinkler line in a certain location and another showing it elsewhere, I’d consult the project specifications and relevant codes (like NFPA 13) to determine the correct placement. If neither drawing aligns with the code, I’d consult the project engineers and potentially the fire marshal to reach a consensus. Documentation of the conflict resolution process is critical, and I always create a revision log detailing the changes and the reasoning behind them.
For example, if a mechanical drawing shows a duct running through a sprinklered area and the sprinkler drawing doesn’t account for the penetration, this presents a significant risk. My process would involve consulting the mechanical drawings to confirm the duct location and size and then coordinating the placement of fire dampers on those penetrations according to NFPA standards. I would then update the sprinkler drawing to reflect the changes and have it approved by the relevant stakeholders.
Q 9. What are the key considerations for designing fire protection systems in high-rise buildings?
Designing fire protection for high-rises presents unique challenges. The key considerations revolve around life safety, property protection, and efficient evacuation. Think of it like building a layered defense system. First, you need robust fire-resistant construction: compartmentalization through fire-rated walls and floors is crucial to prevent the rapid spread of fire. Then, you layer on the active fire protection systems. Sprinkler systems are vital, often requiring higher-pressure systems and specialized riser designs to reach upper floors. Standpipes are equally important, enabling firefighters to quickly access water supplies for effective fire suppression. Stairwells and elevator shafts need to be fully protected with fire-rated construction, smoke control systems (including pressurization and smoke dampers), and potentially dedicated fire pumps. Evacuation plans become extremely complex, often utilizing dedicated fire command centers and advanced communication systems. Finally, thorough design reviews and compliance with specific high-rise codes are non-negotiable, ensuring the integrity and safety of the system.
For example, in a high-rise, you might find the use of a dedicated fire pump room on a lower floor, feeding into a network of risers that reach every level. The design would include detailed calculations to determine water pressure and flow rates to ensure adequate coverage of all floors. The drawings would show the precise placement of these risers, sprinkler heads, standpipes, fire pumps, and all related equipment.
Q 10. Explain your understanding of fire dampers and their placement in drawings.
Fire dampers are crucial for preventing the spread of fire and smoke through ductwork. They’re automatically activated by heat or smoke, effectively sealing off the duct system to limit fire propagation. On drawings, fire dampers are typically represented by a specific symbol, often a rectangle with a diagonal line, clearly labelled as “Fire Damper.” Their placement is dictated by building codes and fire safety requirements. They need to be located in strategic locations such as: at the penetration points of fire-rated walls or floors, within air handling units, or at significant branch points within the duct system. The drawings will show their exact location within the ductwork, and usually will include a detail drawing showing the size, type, and manufacturer of the damper. Proper clearances need to be indicated to ensure they can function correctly without interference.
For instance, a drawing might show a fire damper in the HVAC ductwork penetrating a 2-hour fire-rated wall, clearly indicating its location in relation to the wall and the duct system. A detailed view would show the damper’s specifications, including its size, activation temperature, and whether it’s a single or double damper design. A proper annotation would clearly indicate the NFPA standard reference that mandates this type of damper.
Q 11. Describe your experience with detailing fire sprinkler systems in drawings.
My experience with detailing fire sprinkler systems involves a comprehensive understanding of hydraulic calculations, pipe sizing, fitting selection, and placement of sprinkler heads. I’m proficient in using CAD software to create accurate and detailed drawings, showing the entire network – from the fire pump (if present) and main riser to the individual sprinkler heads. These drawings need to be clear and unambiguous; they need to communicate the location of every component, the pipe sizes and materials, and the system’s overall layout. Each component is depicted using standard symbols, and the drawings should include notes, specifications, and references to relevant codes (like NFPA 13). I frequently use isometric views to showcase the pipe runs and connections better. Detailed schedules are essential, listing out each sprinkler head, its location, and its design characteristics. Collaboration with mechanical engineers and plumbing contractors is crucial to ensure the drawings accurately reflect the final system.

Hi, are you owner of interviewgemini.com? What if I told you I could help you find extra time in your schedule, reconnect with leads you didn’t even realize you missed, and bring in more “I want to work with you” conversations, without increasing your ad spend or hiring a full-time employee?
All with a flexible, budget-friendly service that could easily pay for itself. Sounds good?
Would it be nice to jump on a quick 10-minute call so I can show you exactly how we make this work?
Best,
Hapei
Marketing Director
