4.2 User responsibilities Within the scope of its work activity, the user shall be responsible for identifying and mitigating sources of risk, including point of operation hazards associated with the installation, set-up and operation and maintenance of the machine and machine production system in accordance with clauses 5, 7, 8, 9 and 1 0. 4.3 Modifier responsibilities Within the scope of their work activity, the modifier(s) of a large machine shall be responsible to ensure that the design, construction, modification, installation and safeguarding are in accordance with clauses 5, 6, 7 and 8.
See the ANSI B1 1 series of standards or other relevant standards for additional information. Many of the tasks performed on large machines are similar to those performed on smaller machines of the same type, including but not limited to: · set-up; · set-up verification (CNC program verification/tape tryout, TTO/MTO, machine tryout, ball bar testing, etc.); · automatic operation; · monitoring the point of operation; · workpiece changes; · lubrication; · cleaning; · adjustments; · troubleshooting; · jam clearing; · observation; · preparing for upcoming tool change; · moving the part into and out of the machine; · adjusting coolant / air lines; · removing chips / swarf, often requires entering the machine while machine operation is taking place; · troubleshooting or maintenance with power on; · climbing / working on the machine at height: – adjustment to machine components; – servicing / lubricating the machine; – replacing parts or components. · make adjustments during production mode; · perform tasks from a work station(s) that moves with the point of operation; · unintentional bystanders (entry into the machine envelope by other than the operator); · periodic maintenance.
