An almost identical photograph from another source is also shown below (Figure 2). Clearly any disturbance of these un-braced props could result in collapse in either case. If these props were erected by a householder, the individual was putting his own family’s lives at risk. If they were erected by a builder, the individual was at risk of a manslaughter charge and custodial sentence, should they have failed and caused death.
