Movement:

• rotation

• entanglement (rotating parts with/without projections)

• nipping/drawing-in (gears, nips of in-running rolls, chains, belts)

• shear (sliding parts, spoked wheels, mowing machine blades, dough mixer blades)

• cutting (rotary knives, abrasive wheels, bacon slicers, circular saws)

• linear sliding

• trapping, crushing (closing platens, feed tables and fixed structures)

• shear (between adjacent machine parts, guillotines)

• puncture (nailguns, wire stitching, stapling, sewing needles)

• impact

• abrasives

• friction burns (rotating drums and cylinders)

• abrasions (abrasive wheels, linishers)

• ejection

• material (grinding debris, leaking steam, air, hydraulic oils, dusts and fumes)

• components (process material, components in manufacture)

• machine parts (overload failure, excessive speed, jam up, broken parts)

3.2.2

Stored energy

• air, steam or gas under pressure (pressure storage vessels and operating cylinders)

• springs (actuating cylinders, robots, machining centres)

• sudden release (relief valves,...
