A scrum machine is a potential hazard when it is left unattended in a place where it can be moved and played on in an unsupervised or unauthorised manner.
At all times when not in use, scrum machines must be stored in a way that cannot be accessed by the public, ideally in a locked storage shed.
If there is no storage shed available, scrum machines must be fenced/padlocked off with clear signage identifying it as a danger and not to be used by any unauthorised persons.
If your scrum collapses, the safest thing to do is put FACE or CHEEK in the mud!
