Tailboard Talk Questions Probies Get Asked (And How To Answer Without Looking Like You Crammed)

Tailboard talk is the informal mentoring that happens at every firehouse during the slow hours of shift. The crew is in the kitchen, at the apparatus bay, or on the back step of the rig, and a senior firefighter starts asking the probie questions. The questions are not formal. The setting is not a classroom. But the answers are being graded just as carefully as anything that happens during a written exam.

The questions tend to fall into the same five or six categories across departments. Hose loads and hydraulic calculations. Fire behavior. Knots and tools. SCBA and air management. EMS basics. Department specific SOGs. The reason the same categories show up is that the senior firefighters are checking the foundational knowledge that a probie needs to be safe and effective on a working call. If a probie cannot answer the basics in the kitchen, the senior firefighters do not want them on the back step at 0300.

This post covers the most common tailboard talk questions and the patterns for answering them well. The goal is not to memorize the answers. The goal is to understand the framework well enough that you can answer any version of the question without sounding rehearsed. Probies who memorize answers get caught the moment the question is asked a different way. Probies who understand the underlying material can answer fluently in any phrasing.

The most common tailboard topic by a wide margin. The senior firefighter will ask you about specific hose loads carried on your rig, the friction loss calculations your department uses, and the standard nozzle pressures for the lines you deploy.

Common questions in this category.

What is the friction loss for the 1 and 3 quarter inch attack line at 150 gallons per minute. The answer depends on the formula your department uses. Most departments teach the standard friction loss formula of 2 times Q squared per 100 feet for 1 and 3 quarter inch hose, where Q is the flow in hundreds of gallons per minute. At 150 GPM that is 2 times 1.5 squared, which is 2 times 2.25, which is 4.5 PSI per 100 feet. Then you multiply by the length of the lay in 100 foot sections.

What is the standard nozzle pressure on the smooth bore tip you carry. Smooth bore tips typically run at 50 PSI for handlines. Fog nozzles typically run at 100 PSI. Confirm what your department uses because some departments run smooth bore at 50 for handlines and 80 for master streams.

How much hose is on the cross lay. Standard cross lay configurations are 200 feet of 1 and 3 quarter inch. Some departments carry 150 feet, some carry 250 feet. Know yours exactly.

How would you stretch to a second floor. The standard pattern is the standpipe operation if the building has one, or a hand stretch up the interior or exterior stairs estimating one length of hose per floor for the deployment plus the working length for the fire compartment.

The pattern for answering is to give the principle, then the specific number, then the department variation if there is one. Senior firefighters want to hear that you understand the math and that you know your specific rig.

Fire behavior questions are checking whether you understand what is happening inside the structure when you are deciding how to attack it. The questions are usually phrased as scenarios.

What does dark turbulent smoke pushing out of a vent opening mean. The answer touches on incomplete combustion, fuel rich conditions, and the possibility of impending rollover or flashover. Smoke that is dark and turbulent suggests the fire is consuming oxygen faster than the openings can supply it, and the structure is approaching a critical transition point.

What are the warning signs of flashover. Rapid increase in temperature, smoke layer banking down to the floor, smoke darkening and thickening, the appearance of pyrolysis products visibly rolling across the ceiling, sudden ignition of off gassing materials, and any visible flames showing in the smoke layer near the ceiling.

What are the warning signs of backdraft. Smoke under positive pressure pushing in and out of openings in a pulsing pattern, smoke stained windows, hot doors and walls, no visible flames, and the appearance of a structure that has been burning for a long time in an oxygen limited state.

What is the difference between offensive and defensive strategy. Offensive strategy puts crews inside the structure to attack the fire directly. Defensive strategy keeps crews outside and protects exposures while letting the fire consume the structure. The decision criteria include structural integrity, fire size relative to available resources, life safety profile, and risk benefit analysis.

The pattern for answering fire behavior questions is to describe what you would observe, what it indicates about conditions, and what the appropriate response is. The senior firefighters want to hear that you can read a building and adjust.

Knots questions show up because the fire service still uses ropes and knots for hauling tools, lowering equipment, and emergency self rescue. The senior firefighters want to know that you can tie the standard knots from muscle memory.

The standard knots most departments expect from a probie include the following. Bowline, used for forming a fixed loop at the end of a line. Clove hitch, used for securing a line to an object. Figure eight on a bight, used for forming a loop in the middle of a line. Half hitch, used as a backup to a primary knot. Becket bend or sheet bend, used for tying two lines together. Water knot, used for tying webbing.

Common questions. Tie a bowline one handed. Tie a clove hitch around the bay door post. Show me how you would haul a tool up to a second floor. Show me how you would secure a line to a hose for hoisting.

Tools questions are checking that you know every tool on the rig by name and function. Halligan. Flathead axe. Pickhead axe. Pike pole. Hook of various lengths. Rabbit tool. Hydraulic spreaders. K12 saw. Chainsaw. Each tool has a purpose, a weight, a way to carry it, and a way to use it. The probie who can name every tool on the rig and describe its primary use without hesitation gets credit immediately.

The pattern for answering is to demonstrate, not just describe. If you are asked about a knot, tie it. If you are asked about a tool, show how you carry it.

SCBA questions are safety critical and the senior firefighters take them seriously.

Common questions. What is the rated duration of the bottle on the rig. Most modern departments run 30 minute or 45 minute bottles, though the actual working duration is shorter based on workload and breathing rate. The standard answer acknowledges the rating and the reality.

What is the low air alarm setting. Most SCBA units are set to alarm at 33 percent of bottle capacity per NFPA 1981. That alarm is your warning to start the egress, not the warning that you are about to run out of air.

How do you perform an emergency air share. The pattern involves accessing the trans fill or buddy breathing connection on your unit, connecting to the other firefighter's unit, and transferring air according to the specific manufacturer's procedure. The answer should reference your department's specific equipment.

What is the rule of air management. The standard answer is that you exit the IDLH atmosphere with reserve air, with the goal of being out and on fresh air before the low air alarm activates whenever possible. The rule recognizes that the low air alarm is a warning, not a usable working pressure.

How long do you have to evacuate if the low air alarm activates while you are interior. The honest answer is that it depends on your breathing rate, your distance from egress, and your workload. The general expectation is that you should be able to make egress from a reasonable interior position before the bottle is empty, but the only safe practice is to be near egress before the alarm sounds.

The pattern for answering SCBA questions is to give the rated number, the working reality, and the safe practice. Senior firefighters want to hear that you understand the equipment and that you take air management seriously.

EMS questions are checking that the firefighter side of you can also function as the EMT or paramedic side. Most career firefighters in the United States are certified at least at the EMT level, and EMS calls represent the majority of run volume at most departments.

Common questions. What are the components of a primary patient assessment. The standard answer covers airway, breathing, circulation, disability, and exposure, in that order, with a level of consciousness check and a quick scene safety evaluation upfront.

What are the standard vital signs and the normal ranges for an adult patient. Blood pressure typically 90 to 140 systolic and 60 to 90 diastolic. Pulse 60 to 100 beats per minute at rest. Respiratory rate 12 to 20 per minute. Oxygen saturation above 94 percent on room air. Temperature 97 to 99 Fahrenheit. The ranges vary slightly by source but the senior firefighters want to hear that you know the standard ranges and can recognize an abnormal value.

How do you assess a patient with chest pain. The standard pattern covers OPQRST and SAMPLE history. Onset. Provocation. Quality. Radiation. Severity. Time. SAMPLE covers signs and symptoms, allergies, medications, past medical history, last oral intake, and events leading up to the presentation.

When do you call for ALS upgrade if you are an EMT level provider. The answer involves any patient who meets ALS criteria including altered mental status, significant respiratory distress, chest pain with cardiac features, unstable vital signs, significant trauma, or any clinical presentation outside your scope of practice.

The pattern for answering EMS questions is to use the standard mnemonics and structures rather than freelancing. Senior firefighters and senior medics want to hear that you have the framework, not just the recall.

The questions above are the foundational ones. The specifics will vary by department, by region, and by what the senior firefighter felt like discussing that shift. The pattern for handling tailboard talk well is consistent regardless of the specific question.

Listen to the question fully before answering. Do not start talking on the first three words.

If you know the answer, give it cleanly and concisely. Do not pad the answer with extra commentary. A short correct answer beats a long correct answer.

If you do not know the answer, say so directly. "I don't know that one yet." Do not bluff. Do not make up a number. The senior firefighters will respect honesty far more than a guess that turns out to be wrong.

Follow up the "I don't know" with a commitment. "I'll look that up tonight and bring you the answer in the morning." Then actually do it. Coming back the next shift with the answer demonstrates that you take the gap seriously.

Ask follow up questions if there is interest. Tailboard talk works best when it becomes a conversation rather than a one way quiz. A senior firefighter who is sharing knowledge usually enjoys talking through the deeper material. Engage.

Take notes after the conversation. Not during. Pulling out a notebook during a tailboard conversation can feel performative. Walk away after the conversation, then write down the key points so they stick.

If you want a way to drill the foundational knowledge that comes up in tailboard talk between shifts, StruckBox lets you try sample training modes for free. The daily drill questions and rapid quiz sets cycle through hydraulic calculations, fire behavior scenarios, SCBA standards, knots and tools, and EMS basics across hundreds of questions. Running through them on your own time means that when a senior firefighter asks you in the kitchen, you have already thought through that exact category and the answer comes out cleanly.

Tailboard talk is one of the most underrated training systems in the fire service. It is informal, it is conversational, and it is one of the best ways to build the foundational knowledge that makes a probie into a competent firefighter. Lean into it. Be the probie who shows up with questions, takes the answers seriously, and comes back the next shift better than the one before.
