Study Notes
Driver responsibilities at residential house fires
- Ground Ladders: The driver is responsible for throwing at least two ground ladders on buildings with two or more floors.
- Porch Roof: If the structure is a house in the inner city with a porch roof, the driver should consider laddering this porch roof first to give the inside crew the option of going straight to the second floor.
- Second Ladder Placement: The driver's second ladder should go to a window on the bravo or delta side.
- VEIS: If the interior crew decides they are going to do a VEIS, the driver's first ladder should go to that location.
- Forcible Entry: The driver should determine if there are any forcible entry needs on the first floor besides the door the main engine already entered.
- Natural Ventilation: If there are no immediate forcible entry needs, the driver should start preparing for natural ventilation.
- Vertical Ventilation: Vertical ventilation is the best form of natural ventilation, but it takes time.
- Vertical Ventilation Preparation: If vertical ventilation is being considered, the driver needs to start preparing immediately.
- Determining Vertical Ventilation Method: The driver should decide if the vertical ventilation will be performed from the aerial, platform, or from ground ladders.
- Horizontal Ventilation: If horizontal ventilation is being considered, be sure to consider the location of the fire. Coordinate any type of ventilation with interior companies.
- Ventilation Evaluation: The need for ventilation is a continuous task that will need to be evaluated multiple times throughout the duration of the fire scene.
- Fans and Lights: After natural ventilation has been completed, the driver can start working on fans and lights.
- Powering Lights and Fans: Depending on the ladder company's tools, lights and fans could be powered either by battery or by electricity from the truck’s generator.
- Positive Pressure Fan: Never turn on the positive pressure fan until interior companies say they are ready for it.
- Interior Company Needs: After placing lights and a fan, the driver should check with the interior companies to see what they need inside, such as salvage covers, attic ladder, pike poles, trash cans, shovels, etc.
Driver Responsibilities at apartment building fires
- Ground Ladders: The driver's first task is throwing ground ladders unless there is a victim that needs to be rescued using the aerial ladder or platform.
- Victim Rescue: Just because someone is at a window screaming for help does not mean they are in danger. Is smoke coming out that window? Are they in the unit above the fire apartment?
- Fire Apartment and Exposures: If no one needs to be rescued, the driver should be laddering the fire apartment and the exposure apartments.
- Size-Up: While laddering the building, the driver should also be doing a size-up to determine what type of ventilation will be needed and if the interior companies need anything else done before ventilation is performed.
- Ventilation Considerations: When choosing what type of natural ventilation to use, pay attention to the extent of the fire and how fast it is moving. Is it contained to one apartment, or is it in multiple units? Is it in the attic and starting to spread horizontally?
- Attic Fire: If the fire is in the attic, the outside crew should consider performing vertical ventilation from the aerial or platform to keep the fire from continuing to spread horizontally.
- Small Kitchen Fire: If it is a small kitchen fire contained to one unit, then horizontal ventilation should be adequate.
- Coordination with Interior Companies: As always, coordinate ventilation with interior companies.
- Post-Ventilation: After natural ventilation, the driver should start thinking about what task needs to be done next.
- Salvage Covers: The next task could be taking salvage covers (plastic) to the front door for companies to use inside
- Fans and Lights: The next task could be bringing fans and lights to the incident.
- Master Stream Operations: If interior operations are not going well, the next task could be preparing for master stream operations.
- Radio Communication: Listen to the interior companies on the radio; they will likely notify the outside crew of any specific needs via radio.
Driver Responsibilities at commercial building fires
- Forcible Entry: At many commercial fires, the driver will spend a lot of time doing some type of forcible entry. This could include using a saw to cut roll-up doors or using the saw to get a man door open.
- Forcible Entry Objectives: One of the ladder company’s primary objectives is to get the building opened up so crews can get inside, but more importantly this allows crews to have multiple points of egress.
-
Ventilation Challenges: Ventilating commercial buildings can present many different challenges.
- Limited Windows: Some commercial buildings do not have many windows.
- Roof Cutting: Cutting the roof of a commercial building takes a lot more time, staffing, experience, and training than cutting a residential roof. Most commercial roofs are flat roofs, making it dangerous to cut from an aerial or bucket.
- Building Size: Commercial buildings are also hard to ventilate because of their size.
- Fan Limitations: In smaller structures, wind or positive pressure fans can be used to move fresh air into the interior of the building. However, CFD fans do not move enough air to effectively ventilate most commercial buildings.
Tiller/OSV Firefighter
- Primary Duties: Tiller/OSV firefighters work outside the structure, along with the driver. Some of their primary job duties include ground ladders, ventilation, forcible entry, and lighting.
- Communication: Before exiting the tiller cab, the Tiller Firefighter should communicate with the driver to ensure the apparatus is in its final SPOT and is positioned where it can be used most effectively.
- Full PPE: Tiller/OSV Firefighters should be in full PPE enroute to the incident to allow them to immediately go to work upon arrival.
- Initial Task: The Tiller/OSV Firefighter should first take a ground ladder and attempt to place it in the rear (Charlie side) of the structure.
- Size-Up: During the trip to the rear, the Tiller/OSV Firefighter should be sizing up the structure.
- Complete 360: After placing the ground ladder in the rear, the Tiller/OSV Firefighter should return to the truck for a second ladder. During this return trip, the Tiller/OSV Firefighter should complete a 360 of the structure.
- 360 Purpose: The 360 is to gather information specific to prioritizing ladder company tasks.
-
Size-Up Factors:
- Construction Type: Is this structure residential, commercial, or mixed use? How will the fire spread in this structure, and what type of ventilation will be needed? Is the structure balloon frame, lightweight wood frame, or ordinary construction?
- Basement: Does the structure have a basement? Are there basement windows or exterior access to get into the basement? Is the fire located in the basement?
- Victims: Are there victims hanging out windows or on the ground around the perimeter of the structure?
- Forcible Entry: Exterior doors on the Bravo, Charlie, or Delta sides may need to be forced. Are any windows boarded up or do they have bars on them?
- Utilities: Where are the gas and electric shutoffs located? Is the gas meter located outside the structure? Look for the location of the weather head in case the drip loops need to be cut.
- Ventilation: After placing a second ladder, and in some cases a third ladder, the Tiller/OSV Firefighter should be prepared to go to the roof with the driver for vertical ventilation as needed.
- SCBA: If vertical ventilation is needed, the Tiller/OSV Firefighter should don their SCBA and go to the roof with the driver.
- Teamwork: Working as a team to perform vertical ventilation will ensure the task is completed quickly and safely.
- Lights and PPV Fan: Once natural ventilation is completed, the Tiller/OSV Firefighter should coordinate with the driver to place lights and the PPV fan.
- Negative Pressure Fan: For a basement fire, a box fan to create negative pressure may be a good option.
- Salvage: Salvage is often one of the last considerations for first due Columbus ladder companies. Salvage is lower on the priority list than tasks such as Forcible Entry, Ground Ladders, and Ventilation, which deal with Life Safety and Incident Stabilization.
- Salvage Assistance: One of the ways Tiller/OSV Firefighters can assist with Salvage is by placing salvage covers near the entrance of the involved structure. Another way is by limiting the damage done to the occupant/owner’s belongings.
- Crew Rehab: Rehab for the crew of the ladder company is something the Tiller/OSV Firefighter and the Driver can have set up once the fire has been contained.
- Water Cooler: Stocking the water cooler with bottles of cold water and having extra towels and face wipes on the truck will allow the crew to clean up and hydrate.
- Fans and AC: Setting up box fans at the truck and keeping the cab AC on will give the crew some relief after working.
- Decision Making: The Tiller/OSV Firefighter will have to make decisions on their own, without the benefit of their officer being there to guide them.
- Skill Practice: It is essential that Tiller/OSV Firefighters practice their basic firefighter skills to allow them to perform a multitude of tasks quickly, efficiently, and safely while on the scene of an emergency.
- Fire and Fire Alarm Positioning: When positioning ladder trucks on the scene of fires and fire alarms, drivers should position the ladder for rescue or ventilation the majority of the time.
- Defensive Positioning: If the first arriving company determined immediately upon arrival that it is going to be a defensive fire, then drivers should be positioning their trucks for defensive operations.
- Gas Leaks, Service Runs, Water Responses, Vehicle Accidents, EMS Calls: Positioning the trucks on these types of incidents varies. Many times, drivers have the ability to reposition the truck on these types of incidents as necessary. Many of these runs will not require the use of the aerial ladder. Sometimes the positioning may be just to provide lighting.
- Reading Remarks and Radio Traffic: Reading the remarks on the MDC and listening to the radio traffic can help the crew think about what tasks might need to be performed upon arrival.
- Residential Structures (3 Stories or Less): Position the ladder for vertical ventilation unless victim rescue using the aerial ladder is needed upon arrival. Pay attention to the pitch of the roof and the direction of the peak. The majority of residential houses in the inner city are three stories or less, with some type of peaked roof.
- Multi-Family Residential Structures (3 Stories or Less): Try to determine what section/area of the building the fire is in and position the ladder close to that area. Try to maximize the scrub area with access to windows on the second and third floors, while still ensuring access to the roof for vertical ventilation if needed.
- Houses (4 Stories or More): Position the ladder for vertical ventilation. Try to ensure you can reach a few of the windows on any story above the third with the aerial ladder.
- Multi-Family Structures (4 Stories or More): Try to determine what floor and section of the building the fire is in, and position the ladder close to that area of the building. Make sure to position the ladder to maximize the scrub area. Some of these buildings will have floors that are out of the reach of the aerial.
- Commercial and Mixed-Use Structures: Building construction, the extent of the emergency, and the tasks needing to be performed will guide firefighters on positioning the truck at these types of structures.
- Parapets: Many commercial structures will have parapets; the height of these parapets can vary. Firefighters should remember that parapets are usually shorter near the edge or rear of the building; spotting the ladder to the roof in those locations will make it easier to transition from the aerial to the roof.
- Roof Heights: Some commercial buildings will have different roofs for different parts of the structure, and some of these roofs will have different heights. If possible, try to position the ladder where it can be used to access multiple roofs.
Arrival Order
- First Due Truck Positioning: A common saying in the fire service is that “The ladder gets the front of the building.” SOP 02-02-02 states that the first ladder will generally take the front of the structure, or a position that will be most suitable for the use of the aerial.
- Second Due Truck Positioning: One of the main things to consider is the direction the first due ladder will be coming from. A lot of firefighters will try to ensure the second ladder goes to the rear, but sometimes that is not possible. The driver of the second ladder must decide if they are going to try to make it to the rear, or if the more suitable position for the aerial is on the primary street.
- Third Due Truck Positioning: On most residential fires, the third due ladder company will be RIT and will not have an opportunity to position the truck anywhere close to the actual structure. If the ladder truck can be positioned close enough to the structure to use the aerial, firefighters should ensure they are parking the truck in the most logical position to actually use the aerial device if needed. At larger commercial buildings, especially with members of other companies operating on the roof, the third due truck should be quick to set up the ladder to the roof to give companies working on the roof an additional means of egress.
On-Scene Operations
-
Mental Size-up: From the moment firefighters hear the dispatched address, they should be doing a mental sizeup. Things to consider include:
- Spacing: Is it a commercial building with plenty of space to position the truck? Is it a tight residential street where cars are normally parked on both sides of the road? Is it a street where all the houses are set back 150 feet from the road? Is it a street in an apartment complex with limited access?
- First Due Ladder Positioning: As firefighters on the first due ladder are pulling up to the scene, they should take the time to slow down and spot the truck for the best use of the aerial.
Firefighter Size-Up
- Firefighters should start their size-up as they turn onto the street where the incident is located.
- Assess structure type: single family homes, doubles, apartment buildings, or commercial buildings.
- Identify obstacles: power lines, trees, parked cars.
- Consider positioning for ventilation, rescue, or use the ladder to reach the roof.
- Consider the height and type of structure to help decide positioning.
Obstacles
- Obstacles can be on the ground or in the air: trees, cars, powerlines, cable lines, fences, etc.
- Ground obstacles are normally obstacles for the outriggers.
- Common ground obstacles: parked cars, sewer drains, curbs, utility covers, etc.
- Some CFD ladder trucks have cameras, lasers, or spotlights to help firefighters spot the outrigger in-between cars.
- Air obstacles are normally wires or trees.
- Trees can often be worked around, sometimes cutting branches provides the necessary access.
- Power lines are dangerous & should be avoided. Never let any part of the ladder or vehicle come in contact with wires.
Getting the Cab Out of the Way
- Since aerial ladders do not bend, firefighters must have a straight shot from the turntable to the objective.
- Turning the cab in the opposite direction of the fire will sometimes increase the scrub area.
- Nosing into any structure should be avoided.
- On buildings under three stories, shooting the stick over the cab may not allow for roof access due to the cab being in the way.
Turntable Placement
- Understand where the turntable is in reference to the vehicle.
- The dual axles on the tillers can be used as a reference, since the turntable sits between them.
- Drivers are positioning the turntable when they are spotting the truck.
- The turntable's location determines the scrub area.
- When tucking the aerial under wires, the closer the turntable is to the side of the street the wires are on, the higher the tip will be able to reach on the structure.
Deciding Where to Stop
- Once within reach of the structure (within 100’), ask: "If I spot the truck right here, can I stick the roof?"
- If yes, decide if there is a better position ahead.
- If no, continue driving forward and continue asking: "If I stop right here, can I stick it from here?"
- Once the driver is in a spot where the answer is yes, decide if driving forward some more will put the truck in a better or worse position.
Additional Factors to Consider When Ready to park
- Can the outrigger/s fully extend on the working-side?
- Flight path—are there any obstacles in the flight path to the structure?
- Is this the best place to position to be able to work from the aerial/bucket?
- Are there any data/phone lines that the ladder will need to tuck under, is the turntable close enough to the curb?
Tip Placement on Tiller Ladders
- Tip placement depends on the type of incident, the task, the type of structure.
- Considerations: accessing a flat commercial roof to investigate an AC unit, cutting a ventilation hole on a residential house fire, helping an occupant climb down from a balcony.
Vertical Ventilation (Peaked Roofs)
- Position the aerial so firefighters cutting from the stick or behind the stick are safer on the roof.
Roof Access (Flat Roofs)
- Roof size, building height, parking access, height of parapets, and the incident type play a role in tip placement.
- Ensure the tip of the ladder is visible for firefighters on the roof, and that mounting and dismounting the ladder is possible for a firefighter in full PPE and SCBA.
Tip Level or Slightly Above the Roofline/Parapet
- Option for small flat roofs that are not very high, when the aerial is at a lower angle (30° or less).
- Disadvantages: difficult to see the ladder in a smoky environment.
- Advantages: Firefighters do not have to climb over the beam of the aerial to dismount from the aerial.
Tip Extended Eight Feet or More Over the Roof Line
- Option for larger flat roofs, and/or when the aerial is at an angle greater than 30°.
- Disadvantages: Firefighters cannot just walk off the tip to dismount the aerial.
- Advantages: More of the aerial is visible from anywhere on the roof. When mounting and dismounting, firefighters have more of the aerial to grab to assist them during the transition from the roof to the aerial. Comparable to raising a ground ladder three to five rungs over the roofline.
Squaring the Corning
- Option for any flat roof where the truck can be positioned at the corner of the building.
- Similar concept to the previous page, extending the tip eight feet or more over the roof line, but with the aerial closer to the corner of the building.
- Disadvantages: Requires a significant amount of skill to position the turntable.
- Advantages: Allows the aerial ladder to be seen easily by firefighters working on the roof, and it is easier for firefighters to transition from the aerial to the roof.
Bucket Placement on Platform Ladders
- Incident type, the task needing to be performed, and the amount of space available are the three major factors in bucket placement.
- Are firefighters using the bucket for roof access, cutting a vent hole, rescuing an unconscious victim?
Vertical Ventilation (Peaked Roofs)
- Position the bucket to make it possible to cut from the bucket or with the bucket behind them.
Roof Access (Flat Roofs)
- Position the bucket to make it easy to get in and out of the bucket.
- Use the parapet ladder if needed.
Positioning for Victim Rescue
- Approach a victim with an aerial ladder/platform from above if possible.
- Approach from below may cause the victim to attempt to jump onto the aerial.
Tiller Victim Rescue
- Tip placement changes significantly depending on the situation.
- If the victim is conscious, try to place the tip to allow easy transition from their location to the aerial.
- Simple instructions should be given to keep the victim calm.
Platform Victim Rescue
- Square up the bucket with the objective.
- Get as close as possible to the victim.
- Talk to keep the victim calm.
- If the victim is unconscious, it may be easier to position the floor of the bucket a few inches below the window or balcony.
Defensive Operations
- Positioning is more than just stopping near the structure and putting the stick/bucket in the air.
- Consider transition from offensive to defensive operations.
- CFD ladders have master streams capable of flowing over 1,000 gpm.
Offensive to Defensive
- If the truck was initially positioned correctly, switching from offensive to defensive should be easy.
- For tiller ladders, firefighters will have to retract the aerial, place the nozzle in the waterway position, and secure an engine to handle water supply.
- Platforms will just need to secure a water supply.
- If the officer or crew have any concerns about the ladder truck being parked too close to the structure, reposition the truck.
Defensive on Arrival
- Consider multiple factors when arriving on the scene of a fire that will be a defensive operation.
- Can the ladder truck stay out of the collapse zone (1 ½ times the height of the building) and still be effective?
- Can the ladder truck be positioned on a corner and still be effective?
- Are there any doors or windows where the nozzle could be pointed in at an upward angle to flow water into the structure from underneath the roof? (Has the fire burned through the roof yet?)
- Where is the fire and what direction is it traveling?
- Is the truck far enough from the fire that it will not be damaged by the heat? Never be afraid to apply water to the truck itself to buy some time if the truck needs to be moved.
- Ensure the truck is not positioned under any power lines that could come down.
Residential House Fires
- Driver responsibility is to throw two ground ladders for buildings with two or more floors on the alpha, bravo, and delta sides.
- Driver should prioritize second-floor access, considering the location of the fire and the layout of the structure.
- Driver should assess forcible entry needs on the first floor, and prepare for ventilation if no urgent entry is needed.
- Ventilation can be performed using vertical or horizontal methods: vertical using the aerial or platform, or horizontal using ground ladders.
- Coordinate all ventilation efforts with interior companies.
- Upon completion of ventilation, the driver should place lights and fans, ensuring the positive pressure fan is only turned on when interior companies are ready.
Apartment Building Fires
- Driver’s primary duty is throwing ground ladders, unless a victim needs immediate rescue using the aerial ladder or platform.
- Driver should assess the priority of a victim's rescue, considering if they're actually in danger.
- Driver should ladder the fire apartment and exposure apartments, while determining necessary ventilation and any additional needs from the interior companies.
- Coordinate with interior companies for appropriate ventilation strategy based on fire size and movement.
- After ventilation, the driver should prepare for potential salvage needs, lights and fans, or master stream operations.
Commercial Building Fires
- Commercial fires are significantly different from residential fires, often requiring extensive initial forcible entry and multiple egress points for crews.
- Ventilating commercial buildings requires considerations for window availability, roof cutting time and resources, structure size, and airflow needs.
- Large fans might be needed to ventilate commercial buildings due to insufficient airflow from smaller fans.
- Entire ladder company might be assigned a specific task, such as forcible entry, ventilation, or fire attack, working as one crew.
Tiller/Outside Vent Firefighter
- Tiller/OSV firefighters work outside the structure, supporting the driver with various responsibilities like ground ladders, ventilation, forcible entry, and lighting.
- Their first priority is to place a ground ladder in the rear of the structure (Charlie side).
- Perform a 360-degree size-up of the structure to identify: construction type, basement accessibility, potential victims, forcible entry needs, utility shut-off locations.
- They should be prepared to assist with vertical ventilation, ensuring they wear SCBA and work as a team with the driver.
- They should coordinate with the driver for light placement and positive pressure fan operation, ensuring interior companies have requested the fan before activating it.
- Tiller/OSV firefighters should assist in salvage efforts by placing salvage covers near the entrance and minimizing damage to property.
- They should set up crew rehab materials such as cold water, towels, face wipes, and AC/heat in the cab.
Positioning Ladder Trucks
- Position ladder trucks for rescue or ventilation, unless the incident is confirmed as a defensive fire.
- Residential Structures (three stories or less):
- Position for vertical ventilation, considering roof pitch and peak direction, ensuring it's faster to reach second or third-story windows than to set up the aerial.
- For multi-family structures, position near the fire area to maximize access to windows and the roof.
- Residential Structures (four stories or more):
- Position for vertical ventilation, aiming to reach windows on stories above the third.
- For multi-family structures, position near the fire area to maximize access and scrub area.
- Commercial and Mixed-Use Structures:
- Consider the space and accessibility for positioning the truck.
- Account for different roof heights and parapets.
- Aim for a position where the aerial can access multiple roofs.
- Arrival order:
- First due ladder: generally takes the front of the structure or a position that maximizes aerial use.
- Second due ladder: consider the first due's approach and potential obstacles, aiming for the rear or a position opposite the first truck for better aerial access.
- Third due ladder: typically takes the RIT role and may not have close access. If possible, position for potential aerial use and defensive operations.
On Scene Operations (General)
- Perform a mental size-up upon hearing the dispatch address, considering factors like structure type, accessibility, and parking situation.
- Prioritize tasks based on size-up and execute them efficiently and safely.
- Use training, experience, and common sense in decision-making, especially when operating independently.
- Practice essential firefighter skills to perform tasks efficiently and safely.
Firefighter Size-Up and Approach
- When approaching a scene, firefighters begin their size-up as they turn onto the street.
- They assess the structure type (single-family, multi-family, commercial), potential obstacles (trees, power lines, parked cars), and street conditions.
- The driver determines initial ladder placement based on structure type and height, considering if it's needed for ventilation or rescue.
Obstacles and Ladder Safety
- Obstacles can include ground-level obstructions (parked cars, curbs, utility covers) and aerial obstacles (trees, powerlines).
- Ground obstacles primarily affect outrigger placement.
- Some ladder trucks have cameras, lasers, or spotlights (stab/jack lights) to assist in outrigger placement.
- Aerial obstacles like trees can often be addressed by pruning branches, while power lines are a serious hazard to be avoided at all costs.
Getting the Cab Out of the Way
- Since ladder trucks don't bend, obstacles like the cab of the truck can be moved to improve access to the objective.
- Turning the truck's cab away from the fire can reduce the area blocked by the cab.
- Nosing into a structure should be avoided as it can obstruct roof access.
Turntable Positioning
- The location of the turntable is crucial as it determines the truck's positioning and the "scrub area" which affects the ladder's reach.
- The turntable's position affects the ladder's tip height, particularly when tucking under wires.
Initial Ladder Placement
- When within 100 feet of the structure, the driver assesses if the ladder can reach the roof from the current position.
- If not, they must continue driving forward and reassess at each potential stopping point.
- Once a suitable position is found, additional factors are considered: outrigger extension, obstacles in the aerial's flight path, optimal working position, and proximity to data/phone lines.
Tiller Ladder Tip Placement
- Tip placement depends on the incident type and task, considering if it's for a rooftop access, ventilation, or rescue.
- Vertical Ventilation (Peaked Roofs): Tip placement should allow safe roof access, potentially cutting from the stick or with it behind for support.
- Roof Access (Flat Roofs): Considerations include roof size, building height, access, parapet height, and incident type.
- Tip Level or Slightly Above Roofline/Parapet: Suitable for smaller flat roofs, but visibility might be limited in smoke.
- Tip Extended Eight Feet or More Over Roofline: Allows greater visibility and easier mounting/dismounting, but requires climbing over the beam.
- Squaring the Corning: Places the ladder on a building corner for optimal visibility and access, requiring precise turntable positioning.
Platform Ladder Bucket Placement
- Bucket placement factors include the incident type, task, and available space.
- Vertical Ventilation (Peaked Roofs): Position the bucket allowing ventilation from the bucket itself or with it behind for support.
- Roof Access (Flat Roofs): Placement should prioritize easy entry and exit, and potentially utilize parapet ladders for assistance.
Victim Rescue Positioning
- Tiller Ladder: If possible, approach the victim from above to prevent potential jumps. Tip placement is situation-specific, prioritizing easy transition from the victim's location to the ladder.
- Platform Ladder: Square up the bucket with the objective, aiming for close proximity to the victim's location. Try to keep the victim calm and if unconscious, position the bucket floor slightly below the window or balcony.
Defensive Operations
- Defensive Operations focus on protecting the firefighter and preventing fire spread, using master streams with high water flow.
- Offensive to Defensive Transition: If initially positioned correctly, the transition from offensive to defensive mode should be straightforward.
- Defensive Positioning on Arrival: Consider collapse zones, positioning on corners to provide protection, access points for applying water from beneath the roof, and fire travel direction.
- Placement Considerations for Defensive Operations: Stay out of collapse zones, position on corners for protection, aim water through access points (doors, windows), and ensure the truck is not within range of heat damage or under power lines.
