  33. 33. SHORTFALLS• Any system is only as good as the people who use it• Some operators may be required to sign hundreds of PTWdocuments at the start of shifts. It is so easy to fill out a tickbox, and not check it out at all, physically.• Two thousand years ago workers were dying in confinedspaces due to asphyxiation. Sadly today, it is stillhappening.• Technological advances can and should stop this fromhappening, but cost constraints mean that these equipmentare often not made available.33
