Study Notes

‒ Hand Tools: Proper warning signs include adequate lighting, suitable lighting avoiding stroboscopic effect, and environmentally suitable space. Hazards include tool shattering, handle coming loose, blunt tools requiring excessive force, human error, and misuse. Controls include tools being suitable for the task and environment, information and training, visual inspection, substandard tool repair or disposal, and maintenance.

‒ Portable Power Tools: Higher risk due to greater forces, electricity, petrol, noise, vibration, dust, ejected material, and trip hazards. Controls include careful selection of task and environment, manufacturer's instructions, in-house rules, training and information, supervision, and regular maintenance.

‒ Mechanical Hazards: Includes crushing, shearing, cutting or severing, entanglement, drawing in or trapping, impact, stabbing or puncture, friction or abrasion, and high-pressure fluid injection, which are risks caused by moving parts.

‒ Non-mechanical Hazards: Associated with machinery, including electricity, noise, vibration, hazardous substances, ionizing radiation, non-ionizing radiation, extreme temperatures, and ergonomics, slips, trips and falls, and fire and explosion.

‒ Machinery Safeguarding Methods: Includes fixed guards, interlocked guards, adjustable/self-adjusting guards, sensitive protective equipment (trip devices), two-hand controls, hold-to-run controls, emergency stop controls, protective appliances, and personal protective equipment, as well as information, instruction, training, and supervision.

‒ Fixed Guards: Completely prevent access to dangerous parts of machinery. They are fixed in place and require a tool for removal, which has limitations, such as the potential for improper removal.

‒ Interlocked Guards: Guard open: Power to the machine is disabled when the guard is open and cannot operate until it is in place. Guard closed: The guard is locked shut until the machine returns to a safe condition or until the act of opening the guard stops the dangerous parts of the machinery and disables power. Limitations include the potential for bypassing the system, the possibility of persons gaining access by closing the guard around them, and the need to enforce rules.

‒ Adjustable and Self-Adjusting Guards: Used when it is not possible to prevent access to dangerous parts. An adjustable guard is set manually to a range of positions by the operator, while a self-adjusting guard is usually spring-loaded to adjust itself to the workpiece and requires no adjustment by the operator.

‒ Sensitive Protective Equipment (Trip Devices): Not a physical barrier but use sensors to detect the presence of the operator and stop the machine. They include pressure mats, trip bars, and photoelectric devices. Limitations include the potential for bypassing the system.

‒ Two-hand Controls: Designed to protect the operator's hands. Controls should be more than a hand span apart, and both should be activated and released at the same time, stopping the machine immediately upon release. Limitations include the potential for inadvertent activation.

‒ Emergency Stop Controls: Should bring the machine to a safe stop as quickly as possible. The machine can only be restarted using the reset button, but the release of the button should not restart the machine. Limitations include the potential for inadvertent activation and the possibility of restarting the machine too soon.

‒ Protective Appliances: Designed to keep operators' hands away from danger. They include push-sticks, jigs, and clamps.

‒ Specific Machinery Examples: Bench-top grinder, pedestal drill, cylinder mower, strimmer or brush-cutter, chainsaw, compactor, cement mixer, and bench-mounted circular saw, each with their hazards and control measures. The requirements for guards and safety devices include meeting relevant standards, being strong and robust, being compatible with machine operation, and being difficult to defeat, while also allowing vision and ventilation.

‒ Group Exercise: Choose one specific machine to outline the hazards (mechanical and non-mechanical), control measures, and requirements for guards and safety devices. The hazards and control measures must meet relevant standards, be strong and robust, be compatible with machine operation, not be easily defeated, and allow vision and ventilation.
