Failure to replace guards, damaged perimeter fences that allow access, and bypassed or disabled interlocking systems, are examples of critical safety systems failures that require immediate attention to ensure the safety of people.
When using fall-arrest systems, specialist assistance may be necessary to select appropriate equipment, provide effective training in use and inspection, and develop an emergency retrieval plan to recover a person suspended in a fall-arrest harness. People suspended by a fall-arrest harness for short periods of time may suffer serious health effects, or may have incurred injury during the fall prior to the fall-arrest device deploying.
Where access to the hazard is infrequent, the installation of a fitted guard, that can be removed by use of a tool, may be an acceptable control, where the tool to remove the barrier or guard is not normally available to the operator.
Machines are used broadly in the field of mechanics. The word mechanical refers to the work that has been produced by machines or the machinery. It mostly relates to the machinery tools and the mechanical applications of science.
