Question

which of the following machine parts always require guards? select the 3 answer options that apply. fan blades levers rotating barrels abrasive wheel machinery

Explanation:

• Fan blades: They rotate at high speeds and can cause severe injuries if unguarded.
• Rotating barrels: Their rotation poses a risk of entanglement or impact.
• Abrasive wheel machinery: The abrasive wheels can shatter or throw debris, and guards prevent such hazards. Levers, when properly designed and used, do not inherently require guards in the same sense as the other three as they are more about manual operation and less about rotational or abrasive - related risks.

Answer:

Fan blades, Rotating barrels, Abrasive wheel machinery
