Employer states that "[i]n utilizing the box knife, this claimant was no more at risk for injury that she would have been in countless other daily activities." Employer argues that this case is analogous to Miller in the sense that the activities in which Mr. Miller and employee were engaged at the time of their injuries were similarly "mundane." We need not determine if employer's assertions are true, because they have no bearing on the determination of whether employee's injury arose out of her employment.
The question we must consider is whether employee's injury came "from a hazard or risk unrelated to the employment to which workers would have been equally exposed outside of and unrelated to the employment in normal nonemployment life." Section 287.020.3(3) RSMo. Where the activity giving rise to the accident and injury is integral to the performance of a worker's job, the risk of the activity is related to employment. In such a case, there is clear nexus between the work and the injury. Where the work nexus is clear, there is no need to consider whether the worker would have been equally exposed to the risk in normal non-employment life.
This case is distinguishable from Miller. Here, employee was injured while unwrapping pallets, a necessary activity in the performance of unloading the pallets. Because employee was performing an integral duty of her job of unloading pallets, there is a clear connection (nexus) between the injury and her work; that is, employee's injury came from a risk related to employment. Consequently, there is no need to consider whether employee is equally exposed to the risk of unloading pallets or the risk of unwrapping shrink wrap or the risk of using a box cutter in normal non-employment life.
Mr. Miller, on the other hand, was engaged in an activity incidental to the performance of his job. Mr. Miller's job was to provide asphalt to workers paving a roadway. At the time he was injured, employee was walking to his truck to move the truck to where the workers were paving. Because walking was not integral to Mr. Miller's job of bringing asphalt to the workers, there was no clear nexus between his work and his injury. Because there was no clear work nexus, it was necessary to consider whether
Mr. Miller was equally exposed to the risk of walking in normal non-employment life. Mr. Miller was equally exposed to the risk, so his injury did not arise out of his employment.
As discussed above, a worker's activity can provide the nexus needed to show an injury came from a hazard or risk related to employment. So, too, can the physical condition of the work environment. Where the physical condition of the work environment creates the hazard or risk giving rise to an injury, the physical condition provides the nexus needed to show the injury came from a hazard or risk related to employment. For example, imagine Mr. Miller stepped in a hole and injured his knee while walking to his truck. Under that scenario, because employer sent Mr. Miller to work on the roadway, the hole in the roadway would supply the nexus between work and the injury. There would be no need to consider Mr. Miller's non-work exposure to the risk of holes in the roadway.
Likewise, imagine a spill on a floor. The spill creates a risk of slipping and falling. If a worker engaged in the incidental activity of walking to her workstation slips on the spill and sustains an injury, the spill on the work premises provides the nexus between the work and the accident. Because the risk of the spill is related to the employment, there is no need to consider the worker's non-work exposure to the risk of spills.
