8.2.1 G

ENERAL ADVISES ON SCOUT ROLE AND POSITIONING

 

Avoid to remain in front of the cart or by the cart side. (see the 270° scan angle in Figures 12 
& 13) 

 

Facilitate  the  doors/light  handling in front  of the  cart  trajectory (enough in advance  not to 
interfere with measurement). 

 

To  avoid  the  scout  to  be  caught  within  the  scan  range,  it  is  recommended  that  the  scout 
prepare the room in advance and not “just in front” of the cart 

 

Warn staff and visitors of the presence of the scanning operations, but they should not change 
their trajectory if they come across the cart. 

 

In case the Scout is “caught” in the scan range, it is recommended that he remains still, till he 
finds himself behind the cart and then can resume his activities.  

 

Kindly explains to site guide or demo attendees to remain behind the cart as their permanent 
presence by the side of the cart would create a ghost wall.
