Access may vary during each stage of the machinery and equipment life cycle. For example: • installation or removal o complete access from every area may be required and involve disconnection or connection of services, such as water, air, pipes, installation of electrical cable to switch board • operation o access for set up, operation and adjustment • maintenance, repair, cleaning, alteration or adaptation o access to remote areas may be required.
Note: Safe work practices must take into account the risk of trapping an operator between the EWP and a fixed structure (e.g. overhead beams, electrical cables, pipes).
A simple machine is a device that simply transforms the direction or magnitude of a force. It is a tool that consists of one or more parts, and uses energy to meet a particular goal. The evolution of machines started with the beginning of Industrial revolution, and brought changes in the fields of agriculture, manufacturing, mining, transportation, and technology, due to which there was a profound effect on the social, economic and cultural conditions of the times.
Personal protective equipment. Where it is not possible for emissions to be controlled at their source, or removed or reduced through effective ventilation, extraction or diversion, the use of personal protective equipment (PPE) as a final measure must be considered to ensure safety. PPE is a lower order control and can only be used where higher order controls are not possible or are not totally effective.
