To reduce the risk of injury when people are working on plant or equipment (Refer Definitions) by preventing the item and its components from being set in motion and by preventing the accidental release of stored energy.
This procedure applies to any person (staff, contractor, sub-contractor, self-employed person, student, etc) who is working on plant or equipment at any University of Ballarat premises. Where several people are working on plant or equipment, this procedure applies to every person.
|Work:||All tasks involving inspection, repair, maintenance, adjustments, modifications or cleaning of plant/equipment. This term does not cover the normal operation of plant or equipment.|
|Plant:||All machinery, fixed appliances and services. This includes cranes, hoists, lifts and forklifts, presses, workshop machinery, farming machinery, processing machinery, conveyors, pumps, engines and motors, industrial vehicles, fixed pipe work, electrical installations and cabling, etc.|
|Equipment:||All portable tools, appliances and implements other than plant that are connected to at least one source of energy. This includes household and office electrical/gas appliances, laboratory instruments, portable powered tools, welding gear, passenger vehicles, etc.|
|Out of Service Tag:||
This tag indicates that plant/equipment is not operating correctly or is not ready to be operated and may be unsafe. Any person can place an Out of Service Tag on plant/equipment if they consider it to be unserviceable or unsafe, but they must immediately contact the Physical Resources Directorate to report the matter and update the Lock and Tag Register.
Other people must not attempt to operate “Out of Service” plant/equipment until all faults have been rectified, and the Out of Service Tag has been removed by the person whose name appears on the tag. See Figure 1 below.
This tag indicates that the person whose name appears on the tag is working on the item of plant/equipment, and that the item must not be operated.
A Danger Tag is not in itself an effective isolation device, only a Safety Lock is. Therefore, Danger Tags must only be used in conjunction with Safety Locks. See Figure 1 below.
Safety Locks are used as a physical form of protection for people working on plant or equipment. They are used to lock out energy sources and other hazards that could pose a risk to people.
Each Safety Lock is issued to an individual worker. It has only one key. Once fitted to an item of plant or equipment, it must only be removed by the individual worker to whom it was issued. See Figure 1 below.
|Safety Hasp:||A device used in conjunction with Safety Locks when more than one person is working on an item of plant. It allows each worker to lock the isolation point so that it can only be turned back on when all Locks have been removed. See Figure 1 below.|
|Lock and Tag Register:||This register records the issuing of Safety Locks, Danger Tags and Out of Service Tags. It is kept in the Physical Resources office at each campus, and is maintained by the Physical Resources Directorate. Refer to Forms.|
Unless specified otherwise in the text, the following actions apply to any person planning to work on an item of plant or equipment at the University of Ballarat.
The Actions are:
