2. Toolbox presentation: Hazards associated with machinery and plant October 2006

3. 3 Mines Safety and Inspection Regulations 1995 Prescribe requirements relating to machinery and plant at mining operations Cover the duties of designers, manufacturers, hirers, employers etc. about how plant must be: designed manufactured tested maintained operated Require ‘classified’ plant to be registered and have logbook

4. 4 Major concerns with machinery and plant Moving, hot or cold parts – guarding Working at height – elevating work platforms, fall-arrest equipment, barricading Cranes and hoists – mobility, stability, maintenance Plant under pressure (e.g. pressure vessels, compressors) – pressure relief valves, maintenance High pressure air hoses – restraint, anchoring

5. 5 Moving, hot or cold parts Moving parts – anything that presents a hazard of entanglement Fingers Hands Clothing Hair Hot parts Cold parts

6. 6 Reducing the risks from moving parts Undertake risk assessments and act to reduce risk Eliminate work close to moving parts Provide guarding for moving parts mandatory to guard high speed rotating or moving parts (e.g. cooling fans, drive shafts, couplings) slow moving parts may also be hazardous (e.g. chain drives, sliding parts) Develop safe systems of work around moving parts Use Resources Safety’s audit on Isolation and Tag-out Observe Australian Standard AS4024.1:2006 Safety of machinery

7. 7 Assess the risk Slow-moving parts also present entanglement hazards

8. 8 Assess the risk continued Although the parts were moving slowly on this equipment, an employee’s fingers were caught and crushed between the chain and sprocket

9. 9 Guarding Properly engineered guards and screens are important to reduce risk

10. 10 Working at height Most mines in WA have locations in plants, on the surface or underground where people are required to work at height, or where there is a risk of falling Falls in the workplace range from less than one metre to hundreds of metres Injuries range from minor cuts and bruises to death

11. 11 Falls from mobile plant Falls from plant present a considerable risk to employees It is common to try and fit everything onto the back of a flat bed truck, but safe access is often overlooked

12. 12 Safe work practices when working at height Before working at height, identify all hazards, assess their risks and prepare a safe work procedure Fall-arrest equipment may be essential for some tasks but consider measures to eliminate the task or the risk of falling Only work at height if you have had proper instruction and training and, where required, the proper certification If working from an elevating work platform fitted to a mobile machine, ensure: the platform is correctly secured to the machine you are wearing fall-arrest equipment Ensure tools and loose materials cannot fall on others or are secured to the person or platform

13. 13 Fall-arrest equipment Secure fall-arrest equipment to designated anchor points in the work area, preferably anchor points above the head Make sure all fall-arrest equipment is correctly selected, fitted and well maintained, and people are trained in its correct and safe use Never use worn or damaged equipment

14. 14 Barricading Place signage and barricades in access areas where people are working at height, particularly in places directly below the work area Immediate work area may require barricading to ensure unprotected people do not enter the area Adequate handrails, guards or fences must be provided on all steps, stairs, elevated walkways and platforms, and on any other elevated workplace where there is a risk of injury to employees from falling

15. 15 Hazards for cranes and hoists Mobility Beware of contacting overhead obstructions (e.g. bridges, tree branches, powerlines, roof) when moving plant Stability Beware of uneven or unstable surfaces Maintenance Poor maintenance and operational abuse may cause heavy components to fail and fall, hoses to burst and couplings to separate

16. 16 Cranes checklist Have all the cranes on site been recorded in the classified plant record book and register? Are all the cranes registered with Resources Safety or, in certain circumstances, WorkSafe WA? Has the crane been inspected pursuant to regulations? Does the driver have the appropriate certificate of competency? Is the logbook kept with the crane? Is the logbook up to date? Are pre-start checks and daily inspections being performed? Are there any defects that compromise the safety of the crane? Are all components (e.g. lifting chain slings, hooks, shackles) in good order?

17. 17 Assess the risk Kinked, damaged hoist rope

18. 18 Assess the risk continued What are the discard criteria and wear limits?

19. 19 Elevating work platforms (EWPs) checklist Have all EWPs on site been recorded in the classified plant record book and register? Are all EWPs registered with Resources Safety or, in certain circumstances, WorkSafe WA? Have all EWPs been inspected pursuant to regulations? Does the operator have the appropriate certificate of competency? Is the logbook kept with the EWP? Is the logbook up to date? Are pre-start checks and daily inspections being performed? Are there any defects that compromise the safety of the EWP?

20. 20 Plant under pressure If not maintained and operated properly, compressors and pressure vessels are bombs waiting to explode

21. 21 Pressure vessels checklist Have all pressure vessels on site with hazard levels ‘A’, ‘B’ or ‘C’ been recorded in the classified plant record book and register? Are those pressure vessels been registered with Resources Safety or, in certain circumstances, WorkSafe WA? All typical pressure vessels must be maintained in accordance with Australian Standard AS3788 Pressure vessels with an internal volume >150L must be subjected to a statutory inspection before they are used and then at no more than three-yearly intervals

22. 22 Pressure relief valves (PRVs) Must be installed and proven for correct setting and function in accordance with Australian Standard AS1210 Periodic service and recalibrate or replacement is important Seal from the last test and calibration should be intact Fitting, adjusting and tampering with these safety devices by unauthorised persons should be forbidden by the company

23. 23 High-pressure air hoses High-pressure hoses and fittings on compressors and boosters are a serious striking hazard if they become disconnected Typical operating environment dramatically reduces the working life of hoses Restrain Anchor

24. 24 Assess the risk Are hoses adequately restrained and anchored?

25. 25 Assess the risk continued For many years, the most common methods for restraining hoses were the whip check sling and chain-and-shackle Whip checks still have a place but only in low pressure applications

26. 26 Reducing the risk Minimise the use of high-pressure hoses and design hard-plumbed systems with designated connection points Enable a variety of connection point configurations

27. 27 Reducing the risk continued Full-length hose stockings Anchor point for each leg – 180° separation where possible Designated anchor lug points using rated shackles
