By understanding the role of chainsaws and how to utilize them safely, firefighters can optimize this versatile power tool.

How do chainsaws play a role in firefighting efforts?

How Chainsaws Play a Role in Firefighting Efforts

Chainsaws serve numerous purposes across various firefighting contexts. Their metal cutting teeth powered by gasoline engines cut rapidly through most vegetative fuels and wooden structures. Firefighters employ them to:

Construct firelines and firebreaks

By removing trees, brush, and other flammables in the path of a fire, chainsaws create essential fuel breaks to contain blazes. They clear vegetation down to mineral soil to stop fire spread.

Ventilate structures

Saws cut ventilation holes in roofs and walls, which allows heat and smoke to escape so firefighters can enter safely.

Conduct search and rescue

Chainsaws cut through debris, walls, floors, and other obstacles to access or extract trapped people in burning buildings or collapsed structures.

Remove hazardous trees

Called “snags,” damaged or weakened trees are felled near firelines and roads to protect firefighters from falling branches or trunks.

Extinguish hotspots

Post-fire, saws dig into landscape to expose lingering embers and extinguish them. They also cut burnt trees into smaller pieces to check for hidden smoldering areas.

Construct shoring systems

Saws cut wooden posts and beams used for shoring to stabilize weakened structures and prevent collapse during search operations.

With this versatility, chainsaws are one of the most useful tools for tackling the challenges of fire response. But choosing the right saw and using proper safety precautions are critical.

Chainsaw features and specifications for firefighting

While chainsaws for fire applications share similarities with logging saws, they have customized features to aid firefighters.

Specialty concrete/brick/stone cutting chainsaws

Saws equipped with diamond-tipped chains cut through cement, concrete, brick and natural stone. This enables ventilation and rescue access in urban areas.

Safety features

  • Chain brakes stop the chain immediately if kickback occurs
  • Low-kickback chains and reduced kickback bars lessen kickback forces
  • Guards protect hands if chains derail or break
  • Insulated handles prevent electrical shock from power lines

Reliable start-up

With fires, there’s no time to struggle starting saws. Fire-specific chainsaws start easily and quickly even after long storage.

Robust air filtration

Special air filters prevent fine airborne ash and debris from entering the engine and causing damage.

Serviceability

Easy access to air filters, spark plugs, chain tensioners and other parts aids cleaning, maintenance, and repair.

In addition to chainsaw features, proper safety gear and training is mandatory.

Personal protective equipment (PPE) for chainsaw operators

Chainsaw operators utilize specialized personal protective equipment (PPE), including:

  • Chainsaw chaps – Made of cut-resistant fibers, these protect legs from cuts if the chain breaks or derails.
  • Hard hat with face shield – Prevents head injuries from falling or flying debris. Face shield safeguards face from sparks and sawdust.
  • Hearing protection – Chainsaw engines generate up to 115 decibels of hazardous noise. Earplugs or muffs are essential.
  • Eye protection – Wraparound glasses or goggles shield eyes from sawdust and dirt.
  • Gloves – Cut-resistant gloves defend hands from chains if they slip off bars while sawing.
  • Respirator – Filters out smoke particles and sawdust when working around fires.

Proper PPE minimizes risks posed by chainsaw operation in volatile fire situations.

Chainsaws in structural firefighting

In structural fires in homes, businesses, and other buildings, chainsaws aid ventilation, forcible entry, and search and rescue.

Ventilation and forcible entry

Chainsaws cut strategic vent holes in roofs and walls to release dangerous heat and smoke, allowing safer interior fire attack. They also cut locks, hinges, and other points of entry when forcing door and window access. Specific tasks include:

  • Cutting ventilation holes in roof systems – Vents in pitched roofs require cutting through layers of shingles, plywood, and framing.
  • Breaching concrete and brick walls – Specialty concrete/brick chainsaws equipped with diamond chains cut through these strong materials.
  • Removing security bars from windows and doors – Highly reinforced bars sometimes block access until cut.
  • Dismantling gates, fences, and other barriers – Obstructions encircling structures are dismantled for entry by apparatus.

Rescue operations

Time is of the essence for saving victims in burning, unstable buildings. Chainsaws clear paths for rescuers and allow extraction of trapped occupants through:

  • Removing fallen debris – Saw through collapsed timbers, drywall, furniture blocking access.
  • Cutting holes in floors/walls – Penetrate walls and floors to reach victims more rapidly than hand tools.
  • Widening openings – Enlarge windows, doors to facilitate rescue and stretcher access.
  • Shoring/stabilizing structures – Cut wood support posts and beams for shores to prevent collapses.
  • Assisting extraction from entrapments – Free victims pinned or caught in machinery, furniture with targeted cuts.

With buildings posing so many access and egress challenges, a chainsaw in skilled hands can be the difference between life and death.

 

Chainsaws in wildland firefighting

On the firelines of forest, brush, and grassland wildfires chainsaws are indispensable for constructing containment lines and eliminating hazards.

Fireline construction

Firebreaks and firelines require removing substantial amounts of vegetation quickly and efficiently:

  • Clearing brush/saplings – Sawing down brush, shrubs, and small trees to mineral soil.
  • Felling large trees – Experienced sawyers carefully drop trees away from crew.
  • Widening existing roads – Expanding narrow dirt and gravel roads to accommodate engines.
  • Removing stump – Grinding down stumps near line so they won’t reignite.
  • Trimming branches – Removing low-hanging limbs obstructing apparatus along lines.

Removing hazard trees/snags

Snags are dead or dying trees presenting falling hazards. Sawyers identify and safely drop them away from crews.

Chainsaws in urban search and rescue

Specialized teams employ chainsaws for structural collapse and confined spaces rescue. Key uses include:

  • Breaking up concrete and brick rubble – Gain access to victims trapped under collapsed walls and debris.
  • Cutting vehicle wreckage – Remove crushed metal, panels, parts to reach victims.
