All of the following would be considered workplace injuries EXCEPT:

The scenario involving the employee being struck by a car while in the company parking lot, specifically while walking to the jobsite, is not typically considered a workplace injury. This is due to the concept of "coming and going" rules in workers' compensation law, which generally excludes injuries that occur while an employee is in the process of traveling to or from the workplace.

In this case, even though the incident occurred on company property, the individual was not actively engaged in work-related duties at that moment. This distinction is crucial because workplace injuries are usually defined as those that occur during the performance of work tasks or duties.

In contrast, the other scenarios described involve direct engagement in workplace activities or immediate job-related tasks. For example, being struck by falling debris while at the jobsite and suffering burns from jobsite chemicals clearly align with the definition of workplace injuries as they occur during the performance of work duties. Furthermore, being struck while cleaning the company parking lot also classifies as work engaged in for the employer’s benefit. This reinforces the importance of understanding the context and timing of the events in determining whether an injury is deemed a workplace injury.
