<p> 3 SAFE WORK INSTRUCTIONS FOR OPTICAL MICROSCOPE</p><p>Campus: Clayton, VIC Faculty: Engineering</p><p>Department: School of Physics and Materials Engineering</p><p>Building: 37 Room No: Assessment Date : </p><p>Investigator Phone # Signature</p><p>1. Authorisation  Authorisation from academic-in-charge, Dr Chris Hutchinson is required to undertake work in the metallography laboratory  Potential user should complete the risk control worksheet and assessment  Potential user should be trained by a qualified or licensed user (see Dr Chris Hutchinson)</p><p>2. Hazards associated with equipment/machinery/technique/process:  Operating and viewing the metallurgical microscope may involve sustained awkward postures and repetitive movement  Visual environment may be harsh for the eyes during continual operation of the metallurgical microscope. Glare, reflection, uneven/excessive/poor illumination and poor contrast/resolution could contribute to eye strains and fatigue.  Electrical hazards associated with the use of 240 VAC electrical appliances  Thermal hazard associated with the integral illuminator lamp (i.e. tungsten-halogen incandescent bulb) in the microscope. The light bulb (thus heat sinks and enclosing housing) can generate large amount of heat during operation.</p><p>3. Before you start work:  Training by a qualified or licensed user before undertaking task.  Familiarise yourself with other risks associated with the laboratory;  Visually inspect cables and electrical connections for signs of wear and tear; check that a Work Cover inspection tag is fixed to any cables. 4. Personal protective equipment to be used: None required. 5. The environment where the task is to be undertaken:  Working bench and floor should be dry and clean.</p><p>6. Step by step procedures for task  Remove microscope and lens covers  Turn lamp intensity to low  Turn on power  Set objective to lowest magnification  Ensure stage and sample are at focal point  Increase lamp intensity  Take a five minute break every 30 minutes  On completion, turn off power, replace covers 4 7. Clean-up procedures  Ensure to clean and tidy bench after work has been completed.</p><p>8. Waste disposal procedures N/A</p><p>9. Emergency procedures N/A.</p><p>10. After hours access procedures  After-hours access is restricted; contact Dr Chris Hutchinson for after-hours authorization.  Register your details in the after-hours log book if the metallography lab is to be used after normal working hours.  Only trained and licensed user of the equipment is allowed to enter the log book.</p><p>11.
