text: **3.4 Mobile work, home as workplace and domestic work**
  The place of work — premises of the employer or any other place — is another major characteristic of 
  working conditions, which significantly influences the risks and the preventive measures. This chapter 
  takes a closer look at three types of work, that is, mobile work, private homes as workplace and domestic 
  work, All pose — in a broad sense — similar challenges for OSH.77 
  
  For OSH, the major**question for all mobile and non-stationery work**is:**to what degree**does the 
  OSH level at these workplaces’ deviate**from the OSH level at stationary workplaces**? Current OSH 
  legislation illustrates these difficulties: The Workplace Directive78 excludes several types of mobile work, 
  and the Display screen equipment directive 79 was issued in 1990 and does not reflect the variety and 
  specific OSH issues of digital equipment development of the past 30 years. Both directives are currently 
  under revision. 
  
  **Mobile work**is a standard characteristic of work in the**construction and transport sector**, extreme 
  for workers in the maritime and other long-distance and international transport sectors, often in tourism 
  and also for certain categories of**sales personnel**, and often standard for qualified**craft workers**during 
  service or construction of plants and installations and during maintenance.80
