12.2 Tools, Equipment & Tactical Terms
Key Takeaways
- SCBA is the self-contained breathing apparatus air pack used in smoky, oxygen-deficient, or contaminated atmospheres.
- Chain saws (wood roofs) and K-12 rescue saws (forcible entry, extrication, ventilation) are carried on ladder trucks, ladder tenders, and squads; K-12 has wood, metal, and masonry blades and is often set up with a metal blade for forcible entry.
- A Plug is a fire hydrant; to Lay a Line is to connect hose to a hydrant as the engine moves toward the fire, supplying uninterrupted water beyond the ~500 gallons on the apparatus.
- Forcible entry opens locked access; Extrication removes mechanically trapped victims (often with power tools); Ventilate removes smoke by roofs, fans, windows, or hose lines.
- Search and Rescue systematically locates and removes fire victims; rescue is always the priority at any incident.
12.2 Tools, Equipment & Tactical Terms
Quick Answer: SCBA = air pack for contaminated/smoky air. Chain saw = gas saw for wood-roof ventilation holes (ladders/tenders/squads). K-12 (Rescue Saw) = gas circular saw for forcible entry, extrication, ventilation; three blades (wood, metal, masonry); often metal blade ready for forcible entry. Tool = hand tools (axe, sledge, pike pole, etc.). Plug = hydrant. Lay a Line = hydrant-to-engine hose as you drive in, supplementing ~500 gallons on board. Forcible entry, extrication, ventilate, and search and rescue are the core tactical actions; rescue is always the priority.
If Section 12.1 named the companies, this section names the tools and tactics those companies use. The written exam expects precise definitions—not vague “stuff firefighters use.”
Breathing protection: SCBA
SCBA means Self Contained Breathing Apparatus—the air pack firefighters use to breathe fresh air in smoky, oxygen deficient, or otherwise contaminated atmospheres.
| Element | Packet meaning |
|---|---|
| Full name | Self Contained Breathing Apparatus |
| Common name | The air pack |
| Purpose | Breathe fresh air when the atmosphere is bad |
| Example conditions | Smoke, oxygen deficiency, contamination |
Exam cue: SCBA is about personal respiratory protection in hostile air, not a cutting tool and not a water appliance.
Saws: chain saw vs K-12
Two gas-powered saws appear in the glossary. Do not merge them.
Chain Saw
- Gas powered saw primarily used for cutting ventilation holes in wooden roofs.
- Carried on all ladder trucks, ladder tenders, and squad companies.
K-12 Saw (Rescue Saw)
- Gas powered circular saw used for forcible entry, extrication, and ventilation.
- Carried on all ladder trucks, ladder tenders, and squad companies.
- Many engines have also begun carrying the K-12.
- Comes with three blades: wood, metal, and masonry.
- Most companies carry it with a metal blade in place for forcible entry operations.
| Feature | Chain Saw | K-12 (Rescue Saw) |
|---|---|---|
| Primary use stated | Vent holes in wooden roofs | Forcible entry, extrication, ventilation |
| Blade system | (not detailed as three-blade set) | Three blades: wood, metal, masonry |
| Common ready blade | — | Metal for forcible entry |
| Who carries | Ladders, tenders, squads | Ladders, tenders, squads; many engines too |
Memory: chain saw → wood roof ventilation; K-12 → multi-purpose circular saw, often metal blade first.
Tool — hand-powered workhorses
Tool usually means a hand tool such as an axe, sledgehammer, pike pole, or other manually operated equipment. On the exam, “tool” in the glossary sense is not the engine pump or the aerial ladder; it is the handheld/manual equipment firefighters carry and swing.
Water supply terms: Plug and Lay a Line
Plug
Plug = a fire hydrant. Simple, high-frequency term. If a question says “spot the plug” or “take a plug,” think hydrant.
Lay a Line
Lay a Line is the task of connecting fire hose to a fire hydrant as the engine is driven closer to the fire. That action connects the engine to the hydrant for an uninterrupted water supply to supplement the 500 gallons of water carried by PFD apparatus.
| Lay-a-line element | Detail |
|---|---|
| Action | Connect hose to hydrant while engine advances toward the fire |
| Result | Engine tied to hydrant for continuous supply |
| Why needed | Onboard tank is about 500 gallons—finite without a supply |
Exam trap: laying a line is about hydrant supply, not about patient packaging or ventilation.
Tactical action terms
Forcible Entry
Forcible Entry is forcing a door or other access point with tools or a foot to get inside a locked structure. Link this mentally to ladder-company support work and to the K-12’s common metal-blade setup.
Extrication
Extrication is the removal of trapped victims from smashed automobiles, equipment, or any other place someone may be mechanically trapped. It can be done with hand tools but usually involves power tools. Ladder companies are responsible for extrication (Section 12.1), and the K-12 is listed for extrication work (this section).
Ventilate
To Ventilate is the physical act of removing smoke from a fire-involved building. Methods named in the packet:
- Cutting holes in the roof
- Using fans
- Breaking windows
- Using hose lines
Ventilation supports interior operations and victim survival environments; it is a named ladder support function as well as a free-standing glossary verb.
Search and Rescue
Search and Rescue is activity on fire incidents to systematically locate and then remove fire victims. The packet’s priority line is absolute:
Rescue is always the priority at any incident.
| Term | Core idea | Priority note |
|---|---|---|
| Search and Rescue | Systematically find and remove fire victims | Rescue always priority |
| Extrication | Free mechanically trapped people | Often power tools |
| Forcible entry | Open locked access | Tools or foot |
| Ventilate | Remove smoke | Roof, fans, windows, hose lines |
How tools and tactics map to companies
Use this as a study overlay, not a rigid rule for every call:
| Need | Glossary anchors |
|---|---|
| Hostile air | SCBA |
| Roof ventilation (wood) | Chain saw; ventilate; ladder support |
| Cut metal/forcible entry | K-12 with metal blade; forcible entry |
| Hydrant water beyond tank | Plug; lay a line; ~500 gal onboard |
| Locked building access | Forcible entry; tools/K-12 |
| Car wreck trapped patient | Extrication; often power tools; ladder role |
| Missing/unknown victims in fire | Search and rescue — always priority |
Full tools-and-ops definition table
| Term | Official meaning (compressed) |

| K-12 Saw (Rescue Saw) | Gas circular saw for forcible entry, extrication, ventilation; 3 blades; often metal blade ready |
| Tool | Hand tool (axe, sledge, pike pole, etc.) |
| Plug | Fire hydrant |

| Extrication | Remove mechanically trapped victims; often power tools |
| Ventilate | Remove smoke via roof holes, fans, windows, or hose lines |
| Search and Rescue | Systematically locate and remove fire victims; rescue always priority |
Exam traps to avoid
- Chain saw vs K-12 — wood-roof vent vs multi-use circular saw with three blades.
- K-12 ready blade — most companies keep metal blade in place for forcible entry.
- 500 gallons — reason you lay a line to a plug for continuous supply.
- Rescue priority — search and rescue definition includes “rescue is always the priority at any incident.”
- Extrication location — not only cars; any mechanical entrapment.
Study checklist for Section 12.2
- Define SCBA in one sentence with atmosphere types.
- Contrast chain saw and K-12 carriers and primary uses.
- List the three K-12 blades and the usual ready blade.
- Define plug and lay a line with the 500-gallon fact.
- State forcible entry, extrication, ventilate, and search/rescue without mixing verbs.
- Write “rescue is always the priority” from memory.
These terms turn company names into actions. When a question describes a locked door, a wooden roof, a smashed vehicle, or a smoky hallway, match the scene to the glossary word first—then to the company that typically owns that work.
