Cleaners of vehicles and equipment have occasional contact with others in 45% of jobs; have unimportant dealings with customers in 28% of jobs; never deal with unpleasant or angry people in 6% of jobs; have no responsibility for the heath and safety of others in 11% of jobs; and work with a group or team that is not important to workplace performance in 9% of jobs.  The proposition that cleaners of vehicles and equipment have large numbers of jobs with occasional contact with coworkers and supervisors; no contact with the public; and no teamwork exist in large numbers is demonstrably false.  The Occupational Outlook Handbook reports 2016 job estimates of 369,000 jobs.

A reasonable line of questioning concerns the nine factors listed under the O*NET heading of interpersonal relationships.  If the residual occupational base is less than the full range of cleaners of vehicles and equipment, then the interpersonal relationships can reduce the available number of jobs to less than significant.
