3.1 Grammar & Spelling in Incident Reports
Key Takeaways
- Incident reports serve as official legal documents, public records, and court evidence; grammatical precision prevents misinterpretation during legal proceedings.
- Subject-verb agreement errors frequently occur when prepositional phrases or compound subjects separate the noun from the verb.
- Incident narrative standards require consistent past tense usage, avoiding arbitrary switches between present and past tense.
- Misplaced and dangling modifiers create false statements in incident narratives by attaching introductory action phrases to inanimate objects.
- Common fire service terminology—such as apparatus, personnel, stretcher, ventilation, hazard, and overhaul—must be spelled flawlessly on the NFSI exam.
Grammar & Spelling in Incident Reports
The Critical Function of Grammar and Spelling in Fire Service Documentation
Firefighters must communicate clearly, accurately, and unambiguously in written form. Every incident report, pre-incident plan, training log, and intra-departmental memorandum is a public document subject to legal subpoena, Freedom of Information Act (FOIA) requests, and review by insurance investigators, arson investigators, and municipal officials. A poorly written report can undermine a prosecution, compromise an insurance claim, or damage the credibility of a fire department in court.
On the National Firefighter Selection Inventory (NFSI) developed by IO Solutions (IOS), the Verbal Expression section directly evaluates a candidate's mastery of written English grammar, spelling, mechanics, and syntax. Test items present candidate firefighter narratives, officer statements, or incident summaries and require candidates to identify grammatical errors, select properly formatted sentences, or choose correctly spelled technical terminology.

| • Courtroom Evidence: Incident reports are admissible in court. |
| • NFIRS Metrics: State and national fire statistics rely on reports. |
| • Arson Investigations: Documents origin, cause, and scene status. |
| • Legal Liability: Protects crews and departments from lawsuits. |

Fundamental Grammar Rules for Incident Narratives
1. Subject-Verb Agreement
A verb must always agree in number (singular or plural) with its grammatical subject, regardless of intervening words or phrases.
-
Intervening Prepositional Phrases: Phrases beginning with along with, as well as, together with, in addition to, or of do not alter the singular or plural nature of the subject.
- Incorrect: The captain, as well as four firefighters, were injured during overhaul.
- Correct: The captain, as well as four firefighters, was injured during overhaul. (Subject is the singular captain).
- Incorrect: A line of three supply hoses were laid from the hydrant.
- Correct: A line of three supply hoses was laid from the hydrant. (Subject is the singular line).
-
Compound Subjects with "Or" / "Nor": When subjects are joined by or, nor, either...or, or neither...nor, the verb agrees with the subject closest to it.
- Correct: Neither the officer nor the firefighters were able to locate the main breaker.
- Correct: Neither the firefighters nor the officer was able to locate the main breaker.
-
Collective Nouns: Nouns such as crew, engine company, department, squad, and team take singular verbs when acting as a unified entity.
- Correct: Engine Company 4 has completed its primary search of the first floor.
2. Verb Tense Consistency
Incident reports document events that have already transpired; therefore, the narrative standard is the simple past tense. A frequent error on the NFSI exam is shifting from past tense to present tense midway through a report sentence or paragraph.
- Incorrect: Engine 1 arrived on scene at 14:05 hours. Captain Miller orders a supply line stretch while crew members force the front door.
- Correct: Engine 1 arrived on scene at 14:05 hours. Captain Miller ordered a supply line stretch while crew members forced the front door.
3. Pronoun-Antecedent Agreement and Clear Reference
A pronoun must agree with its antecedent in gender, number, and person. Furthermore, the relationship between a pronoun and its antecedent must be unambiguous.
- Vague Reference (Incorrect): Firefighter Davis told the occupant that his car was blocking the hydrant. (Whose car? Davis's or the occupant's?)
- Clear Reference (Correct): Firefighter Davis told the occupant, "Your car is blocking the hydrant." OR Firefighter Davis informed the occupant that the occupant's vehicle was blocking the hydrant.
- Indefinite Pronouns: Words like everyone, everybody, each, anyone, and somebody are grammatically singular.
- Correct: Each firefighter must inspect his or her SCBA equipment before shift turn-in.
4. Misplaced and Dangling Modifiers
A modifier must be placed adjacent to the word it describes. A dangling modifier occurs when an introductory phrase describes a noun that is completely omitted from the sentence, while a misplaced modifier attaches to the wrong noun.
- Dangling Modifier (Incorrect): While forcing entry through the rear door, heavy smoke pushed out of the structure. (Smoke was not forcing entry; the firefighters were).
- Corrected: While forcing entry through the rear door, firefighters observed heavy smoke pushing out of the structure.
- Misplaced Modifier (Incorrect): Firefighters found a victim unconscious lying in the hallway.
- Corrected: Firefighters found an unconscious victim lying in the hallway.
High-Frequency NFSI Spelling and Homophone Precision
The NFSI exam frequently assesses spelling precision using technical fire service vocabulary and words that are easily confused due to similar pronunciation.
High-Frequency Fire Service Spelling List
| Word | Common Misspelling | Correct Usage in Fire Service Context |
|---|---|---|
| Apparatus | Appuratus, Apparitus | Any complex emergency vehicle (e.g., pumper, ladder truck, heavy rescue). |
| Personnel | Personal, Personell | Staff, firefighters, or emergency crew members assigned to a department. |
| Stretcher | Stretcher, Strecher | Portable gurney or litter used to transport injured or ill patients. |
| Ventilation | Ventillation, Ventelation | Systematic removal of heated gases and smoke from a structure. |
| Hazardous | Hazardus, Hazardious | Pertaining to substances or conditions posing a risk to health or safety. |
| Resuscitation | Resusitation, Resuscetation | Act of reviving a person from unconsciousness or apparent death (CPR). |
| Gauge | Guage, Gague | Measuring instrument used to monitor water pressure or air bottle level. |
| Overhaul | Overhall, Over-haul | Final phase of firefighting to extinguish hidden embers and secure the scene. |
| Occupancy | Occupency, Ocupancy | The purpose for which a building or portion thereof is used or intended to be used. |
| Maintenance | Maintainance, Maintenence | Routine inspection, care, and repair of emergency tools and vehicles. |
Commonly Confused Homophones and Near-Homophones
- Affect vs. Effect: Affect is usually a verb meaning to influence ("Wind conditions affected fire spread"). Effect is usually a noun meaning a result ("The effect of the ventilation was immediate").
- Accept vs. Except: Accept means to receive ("The captain accepted the report"). Except means excluding ("All units responded except Engine 3").
- Advise vs. Advice: Advise is a verb ("Command advised dispatch"). Advice is a noun ("The chief gave advice").
- Principal vs. Principle: Principal means chief/primary ("The principal hazard was structural failure"). Principle means a rule or law ("Fire behavior principles").
- Site vs. Sight vs. Cite: Site is a location ("incident site"). Sight is vision/view ("flames were in sight"). Cite means to quote or issue a violation ("cited for code violations").
Common Incident Report Grammatical Errors Table
| Error Category | Incorrect Report Sentence | Corrected Sentence | Core Rule / Explanation |
|---|---|---|---|
| Subject-Verb Agreement | The inventory of rescue tools and hydraulic pumps were completed at shift change. | The inventory of rescue tools and hydraulic pumps was completed at shift change. | The singular subject inventory controls the verb, not plural prepositional objects (tools, pumps). |
| Shift in Tense | Crew members stretched a preconnect line and force entry into the basement. | Crew members stretched a preconnect line and forced entry into the basement. | Maintain past tense consistently throughout incident narratives. |
| Dangling Participle | Approaching the intersection, the siren was sounded continuously. | Approaching the intersection, the driver sounded the siren continuously. | The introductory phrase must modify the driver, not the inanimate siren. |
| Homophone Confusion | The incident commander issued an order that had a immediate affect on scene safety. | The incident commander issued an order that had an immediate effect on scene safety. | Use effect as a noun indicating an outcome or result. |
| Misplaced Modifier | The crew reported a dog was found by a firefighter in the bedroom that was uninjured. | The crew reported that a firefighter found an uninjured dog in the bedroom. | Place modifiers directly adjacent to the noun they modify (uninjured dog). |
