S-130 Hand Tools 5 — Questions and Answers
Question 1: During extended attack, a crew discovers their hand tools have accumulated heavy pitch and sap residue. Why is cleaning this residue important?
- Pitch adds weight that makes the tool harder to swing accurately
- Residue can reduce cutting efficiency and cause blades to bind in woody material (Correct answer)
- Sap corrodes metal tool heads if left overnight
- Pitch-covered tools are harder to tag and track in tool inventory
Correct answer: Residue can reduce cutting efficiency and cause blades to bind in woody material
Pitch and sap buildup on blades increases friction and binding, reducing effectiveness and requiring more effort from the firefighter.
Question 2: Which condition most commonly causes wooden handles on hand tools to fail catastrophically during use?
- Exposure to sunlight bleaching the wood fibers
- Repeated wetting and drying cycles causing cracks and fiber separation (Correct answer)
- Painting the handle with water-based paint
- Using the tool in temperatures below 40°F
Correct answer: Repeated wetting and drying cycles causing cracks and fiber separation
Repeated wetting and drying causes wood fibers to swell and shrink, eventually leading to cracks, splits, and structural failure under load.
Question 3: What is a 'burnout' in relation to fireline hand tool operations, and what tool is most associated with supporting it?
- A crew member who is fatigued; the McLeod is used to signal rest breaks
- Intentional burning between the fireline and the main fire; the shovel is used to control escaped fire (Correct answer)
- A tool that has been used until it is worn out; the Pulaski is replaced on schedule
- A retardant drop that misses the fireline; the fire swatter extinguishes residual flame
Correct answer: Intentional burning between the fireline and the main fire; the shovel is used to control escaped fire
A burnout removes fuel between the constructed line and the advancing fire, and shovels are used to smother any fire that escapes the intended burn area.
Question 4: Why should the adze (grubbing) blade of a Pulaski NOT be used to strike rocks or mineral soil repeatedly?
- Rock contact dulls the edge quickly and can cause metal fractures or spalling (Correct answer)
- The adze creates sparks that could ignite nearby fine fuels
- Rock striking shifts the head alignment, making the axe blade unsafe
- Regulations prohibit adze contact with non-organic material
Correct answer: Rock contact dulls the edge quickly and can cause metal fractures or spalling
Repeated rock contact dulls the adze rapidly and can cause the blade steel to crack or send metal fragments flying, creating an injury hazard.
Question 5: A crew boss directs firefighters to 'mop up within 300 feet of the fireline.' Which hand tool is most useful for exposing and extinguishing hidden hot spots in deep duff?
- Fire swatter
- Shovel (Correct answer)
- McLeod (rake side)
- Hand saw
Correct answer: Shovel
A shovel can dig into and overturn deep duff to expose buried hot spots so water or dirt can be applied directly to extinguish them.
Question 6: Which S-130 safety principle applies when a firefighter must set down a hand tool on a steep slope?
- Leave it pointing uphill so gravity holds the blade in soil
- Place it flat with the blade facing away from travel paths and secured from rolling (Correct answer)
- Hang it from a nearby branch at shoulder height
- Drive the blade into the ground vertically to keep it visible
Correct answer: Place it flat with the blade facing away from travel paths and secured from rolling
Laying the tool flat with the blade oriented away from where people walk prevents accidental contact and stops the tool from rolling downhill.
Question 7: What is the significance of the term 'tool order' during fireline construction with a hand crew?
- The procurement sequence for ordering replacement tools from supply
- The sequence in which different tools are used as crew members progress along the fireline (Correct answer)
- The ranking of tool importance assigned by the incident commander
- The inspection checklist order followed during morning tool checks
Correct answer: The sequence in which different tools are used as crew members progress along the fireline
Tool order refers to the coordinated sequence in which crew members with different tools (e.g., choppers, scrapers, rakers) follow one another to construct the fireline efficiently.
