2. CONVEYOR STRAINING MODULE 2.1 What is a Lock-out? There is always a danger when working on any machine, whether it is in the factory or at home. Always consider safety before rushing your way into lubricating, fixing, stripping or maintaining a machine. You could categorise working safely into two categories, with one being electrical and the other mechanical. Locking-out a machine would require one to switch off the electricity to the machine but also might require turning off the air or steam supply, depending on the type of machine that has to be locked-out and removing any potential energy that might be present. More often than not the one cannot go without the other. A machine needs to be isolated and locked-out prior to any maintenance being performed, as illustrated in Fig 2.1. Fig 2.1

3. CONVEYOR STRAINING MODULE This ensures that the machine is not operational and that no-one will be able to use it whilst the maintenance procedure is taking place. Each workplace will have its own procedures with regard to lock-out and isolation. The process usually involves: A padlock and key. In some cases more than one padlock and key can be used (please refer to your own company’s lock-out procedure). The key must be kept in a safe place by the responsible person (usually a lock-out supervisor).
