Question

1. for safety purposes, moving parts on machines should be

a. labeled
b. oiled
c. painted
d. shielded

Explanation:

• Labeled: Just naming the parts doesn't prevent physical harm from moving parts.
• Oiled: Oiling is for reducing friction, not for safety from moving parts' physical danger.
• Painted: Painting is for aesthetics or corrosion - resistance, not safety.
• Shielded: Shielding physically covers the moving parts, preventing people from getting caught in them, which is a key safety measure.

Answer:

d. shielded
