Jacks are devices used to lift a motor vehicle off the ground for servicing or other repairs.
For this study, follow-back interviews were not conducted. Typically, follow-back interviews are conducted to obtain a more detailed description of each incident. However, funding limitations precluded this from being done in the present instance. Based upon these 102 cases, an estimated 4,822 persons nationwide were treated in hospital emergency rooms for injuries resulting from the failure of a jack while engaged in an activity involving a motor vehicle during the one-year period. Tables 1 through 9 provide additional details on the persons injured in incidents involving motor vehicle jack failures by the action or situation which produced the injury, the most severely injured part of the body, the injury diagnosis and severity, and the age and sex of the injured person, respectively.
