Off-Highway Vehicle (OHV) Fire and Debris Penetration Hazard Voluntary Standards

  1. 1. Directorate for Engineering Sciences Division of Mechanical and Combustion Engineering (ESMC) July 24, 2019 Public Briefing for The U.S. Consumer Product Safety Commission Off-Highway Vehicle (OHV) Fire and Debris Penetration Hazard Voluntary Standards These presentation materials are those of the CPSC staff, and have not been reviewed or approved by, and may not necessarily reflect the views of, the Commission. 1
  2. 2. Commission Briefing Agenda • Product • Hazard • Incident Data • Voluntary Standards • Meetings With Standards Development Organizations • Summary of Progress • Questions and Answers 2
  3. 3. Products 3 Multipurpose Off- Highway Utility Vehicle (MOHUV) or Utility Vehicle (UTV) All-Terrain Vehicle (ATV) Recreational Off-Highway Vehicle (ROV) Collectively: Off-Highway Vehicles (OHVs)
  4. 4. Fire and Burn Hazards 4
  5. 5. Debris Penetration Hazards 5 Branch Penetration (into occupant area – impalement)
  6. 6. Sept. 19, 2018 Voluntary Standards Meeting on Fire and Debris Penetration 6
  7. 7. Scope of September 2018 Meeting • First meeting on Fire and Debris Penetration with the Standards Development Organizations (SDOs): • Specialty Vehicle Institute of America (SVIA) • Recreational Off-Highway Vehicle Association (ROHVA) • Outdoor Power Equipment Institute (OPEI) • CPSC staff provided an overview of recall data and observations to illustrate the hazards associated with OHV fires and debris penetration 7
  8. 8. Summary of CPSC Staff September 2018 Presentation 8 On the topic of fire, staff: • Provided a list of CPSC recalls • Discussed the lack of preventive requirements in the subject standards • Identified various fire sources indicated in recalls • Recommended industry search literature for existing standards’ treatment of fire hazards • Recommended industry form task groups to study specific categories for both fire and debris penetration hazards. On the topic of Debris Penetration, Staff: • Introduced the issue to the SDOs Staff committed to sharing IDIs on Fire and Debris Penetration
  9. 9. CPSC Staff September 2018 Recommendations 9 CPSC staff presented general categories of fire hazard recalls and recommended, as a starting point for discussion, that SDOs examine other voluntary standards to address: • Fuel System Components • Surface Temperatures • Electrical system fires/Thermal Risks • Exhaust system fires/Thermal Risks • Fires Associated with Flammable Fluids • Debris Fires
  10. 10. Voluntary Standards • ATVs: ANSI/SVIA 1-2017 Four-Wheel All-Terrain Vehicles – Equipment, Configuration, and Performance Requirements (mandatory CPSC standard) developed by Specialty Vehicle Institute of America (SVIA) • ROVs: ANSI/ROHVA 1-2016 Recreational Off-Highway Vehicles (voluntary standard) developed by Recreational Off-Highway Vehicle Association (ROHVA) • MOHUVs (UTVs): ANSI/OPEI B71.9-2016 – American National Standard for Multipurpose Off-Highway Utility Vehicles (voluntary standard) developed by Outdoor Power Equipment Institute (OPEI) 10
  11. 11. Current Voluntary Standard Requirements Related to Fire Hazards • ATV, ROV, and MOHUV (UTV) voluntary standards require: o Spark Arrestor requirement referencing US Forest Service standard USDA-FS 5100-1. • MOHUV (UTV) standard (ANSI/OPEI B71.9-2016) requires: o “All fuel system components shall be located, routed, and contained in such a manner as to provide clearance to heat- generating components and to avoid damage from obstacles or projections that may be encountered during normal operation.” • Above requirements do not specifically address some sources of potential fire hazards illustrated in the recall data 11
  12. 12. There are no requirements addressing penetration hazards through the floor board or wheel well of off-road vehicles 12 Current Voluntary Standard Requirements Related to Debris Penetration Hazards
  13. 13. Post Sept. 19, 2018 Meeting CPSC staff: • Provided the SDOs redacted IDIs related to fire hazards • Suggested discussing 84 IDIs at the second meeting • Suggested 37 IDIs with unidentifiable sources to be held for later discussion • Provided the SDOs with 8 redacted IDIs related to debris penetration hazards 13
  14. 14. Recall and Incident Data Fire and Burn Hazards 14 • 57 recalls for fire and burn hazards (from 2004 to 2019) involving ATVs, ROVs, and MOHUVs (UTVs) o 2776 incidents o 35 injuries • 121 in-depth investigations (IDIs) related to fire and burn hazards (from 2004 to 2017) in off-road vehicles o 22 injuries • Types of Injuries o 1st, 2nd, and 3rd degree burns
  15. 15. Recall and Incident Data Debris Penetration 15 • Recall 16-714 (expansion of previous recall, 14-741) o involved 628 incidents of debris cracking or breaking through floor boards of vehicles o 8 reports of injuries to lower extremities • 8 IDIs related to debris penetration o 4 deaths o 3 injuries • Types of Injuries o Contusions o Abrasions o Abdominal penetration: stomach, liver, spleen, pancreas
  16. 16. Summary of June 27, 2019 Voluntary Standards Meeting 16
  17. 17. Summary of June 2019 SVIA Presentation • Categorized the 84 fire hazard-related IDIs: o by vehicle type: ATV, ROV, MOHUV (UTV) o by injury/non-injury and fire/non-fire incident • Identified 23 IDIs as indeterminate/unknown • Two slides on debris penetration categorizing the incidents as high severity, low-occurrence events 17
  18. 18. Concerns Expressed by the SDOs • Challenges with Developing Standards Requirements: • Vehicle Complexity • Different usage of ROV vs MOHUV (UTV) • Standard requirements may not address all hazards, for example assembly errors • Fire hazard IDIs – low incident rate per category • Debris Penetration IDIs – infrequent incident rate, speeds at 20-25 mph 18
  19. 19. Conclusions of June 2019 Meeting • Instead of category-specific task groups, the industry members preferred to maintain one large group to meet and work with CPSC staff • CPSC Staff requested SVIA’s presentation to be shared and used as a starting working document to categorize and review IDIs • The SDOs and CPSC staff will reconvene later in the year after the SDOs and CPSC staff have had an opportunity to review and analyze the SVIA slides and IDIs 19
  20. 20. Summary of Progress • CPSC staff believes recall and IDI incidents indicate additional voluntary standard requirements for OHVs may reduce many of the recurring incidents related to fire/burn hazards and debris penetration hazards. • CPSC staff has given recall information and redacted IDIs to the SDOs and, to date, staff’s analysis of the IDIs generally agree with industry’s analysis on major category areas (electrical, debris fire, mechanical). • CPSC staff will continue meeting with the SDOs to compare and discuss analyses of the data. 20
