Other risks include hearing loss due to noisy plant and musculoskeletal disorders caused by manually handling or operating plant that is poorly designed. Designers, manufacturers, importers and suppliers have an important role in ensuring, so far as is reasonably practicable, that the plant they design, manufacture, import or supply is safe before it is introduced and used in the workplace. 1.1 The meaning of key terms Plant includes any machinery, equipment, appliance, container, implement and tool, and includes any component or anything fitted or connected to any of those things. Plant includes items as diverse as lifts, cranes, computers, machinery, conveyors, forklifts, vehicles, power tools and amusement devices. Plant that relies exclusively on manual power for its operation and is designed to be primarily supported by hand, for example a screw driver, is not covered by the WHS Regulations. The general duty of care under the WHS Act applies to this type of plant. Certain kinds of plant, such as forklifts, cranes and some pressure equipment, require a licence from the WHS regulator to operate and some high-risk plant must also be registered with the WHS regulator. Competent person means a person who has acquired through training, qualification or experience the knowledge and skills to carry out the task. A competent person has a more specific meaning in the following circumstances: For design verification, the person must have the skills, qualifications, competence and experience to design the plant or verify the design. For inspection of plant for registration purposes the person must have: o educational or vocational qualifications in an engineering discipline relevant to the plant being inspected, or o knowledge of the technical standards relevant to the plant being inspected. For inspection of mobile cranes, tower cranes and amusement devices the person must: o have the skills, qualifications, competence and experience to inspect the plant, and be registered under a law that provides for the registration of professional engineers (in jurisdictions where such a law exists), or o be determined by the WHS regulator to be a competent person. Fail safe means a state or condition where, if any component or function of the plant fails, a system exists to prevent any increase in the risks. For example, if the primary hoist brake fails on a crane lifting a person in a workbox, the secondary hoist brake will prevent SAFE WORK AUSTRALIA MEMBERS’ MEETING 6 PAGE 6 OF 52

uncontrolled dropping of the workbox. However, once the secondary brake is engaged, a lower level of safety has been reached. The situation must be made safe and the fault rectified so that the fail safe capability is re-established. The reliability or safety integrity of the fail safe system should be commensurate with the determined level of risk (for example, Category 1 to Category 4 applied in AS 4024: Safety of Machinery ).

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
