Reading Comprehension - Applying SOG 4.3 at 02:10
The following excerpt appears in the Riverton Fire Department study packet you were issued before the promotional exam:
4.3.1 No member shall enter an IDLH atmosphere unless at least two members are positioned outside the structure and able to initiate rescue. 4.3.2 The incident commander may set aside 4.3.1 only when a known life hazard exists. The commander shall announce the reason over the radio and document it on the incident report. 4.3.3 Members shall leave the hazard zone immediately when a low-air alarm activates and shall notify the incident commander. 4.3.4 Members who work in an IDLH atmosphere for 30 minutes shall report to rehabilitation for at least 15 minutes before re-entering.
It is 02:10. Engine 4 arrives first at a two-story duplex with smoke pushing from a second-floor window. A woman on the sidewalk says her father sleeps in the back bedroom. The second-due engine is four minutes away and the battalion chief is ten minutes out. Your company officer looks at you and says, 'You have the SOG. What do we do?'
1. May Engine 4's crew enter the duplex before the second engine arrives? Answer using only the four sections above, and name the two things that must happen if the answer is yes.

The only lawful path in is 4.3.2. Read on its own, 4.3.1 forbids entry: one crew inside with nobody outside able to rescue is exactly the condition it names. 4.3.2 is the sole exception, and it is written as a two-part test:
- A known life hazard exists - not a possibility, not a rumor.
- The commander announces the reason by radio and documents it on the incident report. Both verbs are 'shall,' so both are mandatory.
The report from the woman cuts both ways. She is an occupant who names a specific location ('back bedroom'), which is the strongest kind of information the section contemplates - far stronger than 'somebody might be in there.' But she is also outside the building and may be wrong about who is home. The commander's radio transmission is where that judgment becomes visible: 'Engine 4 on scene, occupant reports one victim in the rear second-floor bedroom, entering under 4.3.2.' That single sentence satisfies the announcement, records the basis, and lets later readers audit the decision.
Two things the SOG does not do: it does not turn the arriving chief's ten-minute ETA or the four-minute second engine into a waiting requirement, and it does not let the commander skip the documentation because the rescue 'worked out.' The exception is procedural, not retrospective.
2. At 02:31 a firefighter inside reaches 28 minutes of IDLH work time and his low-air alarm activates. He is 40 feet from the door. Which section governs his next move, and what exactly must he do and say?
Read the worked answer
4.3.3 governs, and it governs immediately. The trigger is the equipment state, not the clock. The word 'immediately' is attached to leaving the hazard zone, and notification to the IC is a separate 'shall' - the exit is not conditioned on getting an acknowledgment on the radio.
A tempting misread: treating 4.3.4 as a right to stay two more minutes to reach 30 and 'do it properly.' That inverts the text. 4.3.4 is about rehabilitation before re-entering; it never authorizes staying inside, and it cannot override a shall that fires at 28 minutes.
Radio content should be short and useful to the people who have to come get him: unit and name, location and floor, 'low-air alarm, exiting,' and the route out. The outside team can then position on that route rather than guessing.
After he is out, 4.3.4 only bites if he is assigned to go back in - then rehab comes first. Practically that is academic: a member who just alarmed out is not returning to an IDLH atmosphere on the same air, and the IC needs to hear 'member out of air' so the staffing picture is honest before any other task is assigned.
3. Two hours later, the commander says, 'We didn't really waive anything, so leave 4.3.2 out of the report.' Evaluate that statement against the text.
Read the worked answer
The statement is a conclusion, and the report needs a fact. The question to settle first is not editorial but factual: at the moment the first member crossed the threshold, were two members outside, in a position, and able to initiate rescue?
- If yes, 4.3.1 was satisfied, no set-aside occurred, and 4.3.2 has nothing to document.
- If no, 4.3.1 was not met, and 4.3.2 was invoked whether or not anyone used the word 'waiver.' The report must say so, with the radio time and the reason announced.
The word 'able' carries the weight. Two members masked up, on air, at the door with an assignment are able. A pump operator alone at the panel in a t-shirt, with no SCBA and no assignment to the entry crew, is arguably not - and a report that lists him as one of the 'two out' is the version that gets someone hurt in the next fire and discredited in the review after it.
Write the timeline: who was outside, at what time, with what equipment, and what was said on the radio. If that timeline shows a gap, the gap is what the report exists to capture. A report that omits an invoked exception because the outcome was good teaches the next crew that the exception is optional.
