Written subject 3
Machinery and equipment safety essentials
Organize danger points, guards, inspection, and maintenance by machine motion and worker access.
Draw the direction of motion
Crushing, cutting, nip points, and entanglement differ by motion and access. A quick arrow sketch clarifies what the guard must prevent.
Classify guards by function
Compare devices that prevent access, stop a dangerous state, or separate hands from the point of operation instead of memorizing names alone.
Isolate energy before maintenance
A stop button is not full energy isolation. Cleaning and repair scenarios require control of unexpected startup and stored energy.
