Sledding and Tubing Injuries

Written by a parks and recreation expert

TASA ID: 12

Sledding down a hill is a fond wintertime memory.  Impacting a fixed object or being propelled airborne while sledding tends to dull the memory.  There are many factors that can contribute to the frequency and severity of sledding injuries.  Location, location, location matters in real estate sales as it does in picking a sledding hill.  Public land, private land, or commercial establishments have different levels of care that must be provided to sledders.

Public land may be a natural hill in a park or a designed/designated sledding hill.  Private land with similar public land topography in some states may be covered by landowner recreational use immunity.  Public land used for sledding, whether a designed hill or just a natural hill, will normally be required to meet the standard of care.  Commercial sledding and tobogganing hills/chutes must meet the standard of care.

The wooden sled with metal runners is the only partially steerable apparatus.  Plastic saucers or disks, sleds and sheets go where gravity and the fall line dictates.  The plastic disks or saucers also rotate so that the heaviest person on the disc (saucer) goes down the hill first (meaning, the heaviest person goes down backward).  Toboggans usually have a fixed chute to travel down the hill with an open outrun.

A sled/toboggan recently purchased should have safety warnings in the packaging or on the sled/toboggan.  Plastic sled/saucer/sheet manufacturers have provided a safety warning about hazardous conditions/actions to avoid when sledding.  Safety warnings should include:

  • Number of persons/total weight on apparatus
  • Location of where to use
  • Device is not steerable

Impacts cause many injuries to sledders.  Impacts with other sledders, with terrain features, with fixed objects on/near hills are most common.  Trees and fence posts are the most commonly impacted fixed objects on sled hills.  Other sledders and other season’s recreation equipment left at the base of a sled hill are impact objects.  If the outrun on a sled/toboggan hill is short, an overloaded (too heavy) sled/toboggan can overshoot the designed outrun and hit whatever.  Sledders falling off sleds before completing the downhill run can be impacted by the next sledder if allowed to begin sledding before previous sledder has completed the run.  Supervision procedures should be in place to ensure sledders do not initiate a run before the chute is clear of prior sledder.  Impacts with the sled hill seem improbable but do happen when soft snow is allowed to be pushed into mounds that create a wave surface.  A wave or bump in the sled hill surface allows the vertical force to be transferred to a horizontal force causing the sled to become airborne resulting in a hard impact with the surface.

Lighting conditions can affect the safe operation of a sled hill.  A cloudy overcast day can cause flat light. Without direct sunlight no shadows are present for the human eye to distinguish changes in elevation or if a six-foot tall ice hardened snowball is at the bottom of the hill.  Artificial lighting should produce 10 lumens per square foot across the entire sledding area for night time sledding.

Sledding hill regulations should be posted at the entrance of the path, at the top of the sled hill, and in a warming house, if provided.  The slope, surface and width of the entrance path should be wide enough to accommodate upward and downward walkers carrying sleds and toboggans.  Handrails should be provided but not impactable by sledders descending the sled hill.  Mechanical means such as rope tows or chair lifts must conform to state regulations and have engineer certification.

Single lane sledding hills are usually associated with commercial sledding hills and as auxiliary activities at ski hills.  The half pipe maintenance machine used for snow boarding chutes is used to make a series of single lane downhill chutes for inner tubes or other non-steerable devices.  Generally, these commercial tubing slopes will have a tow rope to pull the sledders back up the hill.

On a large open slope, the top of the hill should have control gates that spread out the sledding lanes. The control gates will keep some space between the sledders as they proceed down the hill as well as require the next in line to wait and allow space to develop between sledders.

The slope at the top of the hill should be one to one, or two to one,  for the first 20 feet of the down hill run.  The slope should then proceed at four or six to one then gradually to a flat runout to the horizontal plane.  The outrun depends on the amount of weight put on a toboggan or sled.  Four 200 pound adults will travel much further and faster than four 50 pound children.

The Northern Hemisphere orientation of a constructed downhill sledding run should have the top of the hill on the south side with the down hill run going toward the north.  The east to west or west to east slope should be even so that sledders going down the hill on non-steerable devices do not drift into the other sledding lanes, fence or other objects on the side of the sledding hill.

    Scott McIntosh, Lewis McIntosh & Teare, Royersford, PA

  • As a busy practitioner, managing a sizeable caseload, I can use all of the help available to me. If I can outsource a task, particularly one as important as securing a qualified expert, I will jump at the opportunity. I use TASA in nearly every case where I need to find an expert witness, be it an engineer, an architect, an economist, etc. They have thousands of qualified experts to refer in virtually any field. Best of all the process is extremely simple. When I need an expert I simply contact TASA, whose knowledgeable representatives ask you targeted questions about your case, your legal theories, and your goals, in order to find the right expert for your case. I usually receive CVs and calls from the potential expert within hours. If you find the originally selected person is not a good fit – for whatever reason – TASA will work with you to find the right person. I would happily recommend this service to any attorney."

    Patrick K. Gibson, Gibson & Perkins PC, Media, PA

  • Ms. Darlie I. McDonald RN was awesome on the witness stand, and we prevailed in our case to the tune of  [a] (highly unusual [amount] for a medical malpractice [case] in our area).  I'd highly recommend her."

    Shane Reed, Shane A. Reed Law Office, Jacksonville, OR

  • I appreciate your inquiries and offers of assistance as well as the consistently high-quality, well-organized, and erudite TASA webinars, which invariably have excellent presenters."

    Maurice S. Kane, Cummings McClorey Davis Acho and Associates PC, Riverside, CA

  • Steven Kursh was an outstanding technical expert on our ecommerce IP lawsuit. He completed a massive amount of work on extremely complicated material, in a very short period of time. His work product was first rate and I think he would have done a terrific job if the case proceeded to trial. He is very articulate and helped us. I only wish we had gotten him involved sooner in the litigation."

    Daniel J. Brown, Reiss Sheppe LLP, New York, NY

  • I thank you all for the response to my request for an expert witness...Both Mr. Scott and Mr. Bianchi appear to be well-qualified for this case, but we have hired another expert. As always, I was impressed by TASA's ability to produce exceptionally well-qualified candidates with great speed."

    John Thomas Dzialo, The Law Offices of John Thomas Dzialo, Santa Ana, CA

  • Thank you for your quick response and the names of the two proposed experts. The situation that gave rise to our search for these experts has resolved and we will not need to retain them. However, we will continue to keep TASA in mind as these needs arise from time to time as your breadth of coverage for experts of all types is unparalleled, in my experience."

    Bart W. Brizzee, County of San Bernadino, San Bernadino, CA

  • I have used TASA for the last five years for locating an expert for many personal injury cases. On each and every occasion, TASA was able to find me more than one qualified expert. With such a variety of experts, I was able to select one who met my client's needs in prosecuting these claims. I found the experts TASA referred not only qualified, but available on a moment's notice. Your fees are reasonable and fair, and I will continue to use TASA for the remainder of my career."

    Robert Oushalem, Esq., The Law Office of Robert Oushalem, San Jose, CA

  • I recently used TASA for the first time to locate an expert to testify in a case requiring rather unusual expertise and where there were no applicable regulations or standards for guidance. TASA referred an expert in California who was everything a lawyer looks for in a forensic expert. He was promptly available for consultation, efficiently prepared for deposition and trial and very persuasive and credible with the jury. TASA's administrative services and assistance in locating this expert were excellent, and we would certainly use both the expert and TASA in the future."

    Theodore Phillips, Miller Hauser Law Group, LLP, Placerville, CA

  • TASA has always given me first-class service, but in a recent matter, TASA found the 'needle-in-the-haystack' expert witness we feared didn't exist. We needed an expert for a very narrow and limited issue in a very narrow and limited industry. Because TASA has an extensive expert witness database, it was able to give us a referral almost on the spot. It's why I always turn to TASA first."

    Kathleen A. Herdell, Law Offices of Kathleen A. Herdell, St. Helena, CA

  • There are numerous companies that provide litigation experts. However, I always choose the TASA Group because of their quick response in finding a qualified expert for my particular case. I have extreme confidence in the TASA Group and will continue to use their services in the future."

    Katie A. Killion, Esq., Chiurazzi & Mengine, LLC, Pittsburgh, PA

  • I spent hours trying to locate an expert in a very technical case involving a defect in a medical device. I could have saved a lot of time by calling TASA first. Within hours, I was supplied with the name of an engineer who had more than 30 years of job training, education and expertise in the precise area involving the device. Bravo TASA!"

    Timothy W. Peach, Partner, Peach & Weathers, San Bernardino, CA

  • We were involved in a case pending for more than five years with seven parties from three states. Three mediations failed before we looked to TASA for an expert. TASA referred an expert who clearly understood the complexity of the project and could effectively support his opinion. If it weren't for his expert advice and deposition testimony, the case would not have settled. Interestingly, the case settled within 90 days from the date this expert began."

    Renee Colbert, Esq., Corporate Counsel, W.G. Tomko, Inc., Finleyville, PA

  • Using TASA to find experts for defending our client in a negligent homicide case ended up being one of the most important decisions we made in trial preparation. The experts they suggested were exactly what we needed for the case. I truly did not expect to find experts that would be such a perfect fit for the nature of case. TASA provided us with highly qualified experts in somewhat narrow fields of expertise. A large percentage of our victory is due to the experts recommended by TASA."

    Marta Farmer, Esq., Carl S. White Law Office, Haver, MT

  • I have used TASA's services since the 1980's and have never been disappointed. TASA is indispensable for locating that hard-to-find expert. TASA representatives have always been courteous and pleasant, with the attitude that they cannot do enough to help. I expect to continue using TASA throughout my career."

    Brad W. Greenberg, Esq., Smyth Law Offices, P.C., Brockton, MA

  • I needed to retain a multitude of scientists from a variety of disciplines for a complex litigation. Initially, I went through a series of interviews with an extremely knowledgeable and professional team of TASA advisors. They were able to find highly qualified experts in the specific fields, all of whom turned out to be superior in qualification and area of expertise to my adversary’s experts. I am a TASA believer!"

    Nooshin Namazi, Partner, Nicoletti Hornig & Sweeney, New York, NY

  • TASA always comes through in the difficult IP cases. Their representatives work with you to refine the search criteria and quickly send you a list of very qualified experts."

    Timothy L. Boller, Principal, Seed Intellectual Property Law Group, PLLC, Seattle, WA

  • Special thanks to our TASA referral advisor for her quick response to our initial request—we were extremely happy with how fast TASA was able to assist us! Your group does excellent work, and it is always my first stop when looking for an expert."

    Susanne K. Sullivan, Senior Attorney, Southwest Airlines Corporation, Dallas, TX

  • When we needed an expert in a patent infringement lawsuit, we turned to TASA. We were looking for a witness qualified in two unrelated technical areas, and TASA worked with us to identify and refine our requirements. TASA performed well, promptly providing us with several excellent candidates to consider, one of whom we retained."

    Joseph T. Miotke, Partner, IP Practice Group, Michael Best & Friedrich LLP, Milwaukee, WI

  • Our team had a very positive experience with TASA. The Expert was professional, efficient, and certainly an expert in his field. His work and testimony contributed to a winning decision for our client! We will recommend the Expert and TASA whenever appropriate."

    Stephanie Sprague, Esq., CT

  • (The Expert) WAS A PERFECT FIT for my case: qualified, competent, easy to work with, attentive to detail, knowledgeable, smart, communicative, enthusiastic, resourceful—have I left anything out? I highly recommend TASA and would be happy to share my experience with anyone else. Thank you!"

    Michael Porrazzo, Esq., The Porrazzo Law Firm, Mission Viejo, CA

  • The expert was very thorough. TASA was quick to respond with an answer to my request. I have used TASA in the past under various other law firms and have been pleased. TASA continues to live up to expectations and then some."

    Anne Desormier-Cartwright, Esq., Jupiter, FL

  • Your organization found us an appropriate expert witness in less than one day. This was excellent service. The expert you found was excellent and a pleasure to work with."

    William A. Ehrlich, Esq., Allentown, PA

  • (The Expert)…accomplished exactly what we wanted. TASA was very prompt and efficient in locating him. All fees were reasonable."

    J. Michael Lehman, Esq., Bruce, Bruce, & Lehman, Wichita, KS

  • We needed an Internet expert right away to meet a deadline. One phone call to TASA, and in less than a day, TASA called back with a list of 8-10 experts who were exactly what I needed. The TASA expert I chose knew the business and mechanics of the Internet so well—he was a PhD and professor who had written a book on the subject—that he put the fear of truth in the defendant that caused him to settle. When I get the kind of service that I did from TASA, I stick with it and use it again and again."

    Philip Green, Attorney at Law, Green and Green, San Rafael and San Francisco, CA

  • Excellent—in a word. I just do not have the time to hunt for experts. (The Expert) was fantastic. Thank you for providing such a quality service."

    Francesca Carinci, Esq., Steubenville, OH

  • TASA stands for Tops At Serving Attorneys. It’s always rewarding working with TASA."

    Marshall A. Bernstein, Esq., Philadelphia, PA.
