What risks should machine guarding on a packaging machine primarily address?

• Prevent pinch: fixed guards on shafts, gears, chains; openings ≤6 mm.
• Prevent burns: heat-seal bars need thermal guards; isolate surfaces >60°C.
• Prevent entanglement: interlocked guards on film and pull rollers; stop on opening.
• Prevent cuts: transparent guard at cutting zone; access only via feed opening.
• Prevent restart: guards with safety interlock switches, CE EN ISO 13849 PLd.
