Which precaution is required to prevent accidental falling when machinery is raised for repairs?

• A. It should be securely blocked to prevent accidental falling
• B. It should be kept free of tools
• C. It should be moved gently to a lower rack
• D. It should be painted with a warning color

Answer: (A)

When equipment is raised for repairs, the key precaution is to secure it with blocking. This creates an independent, solid support that will hold the machine in place even if the lifting device loses pressure or slips, preventing a sudden drop. Use properly rated cribbing blocks or other sturdy supports placed on a level, solid surface under stable load points, and arrange them so the machine cannot shift or settle. Relying on the jack or hydraulic system alone is dangerous, so the blocks must remain in place until the work is finished and the machine is safely lowered. Other options like keeping tools away or painting a warning color don’t physically prevent a fall, so they don’t provide the same essential protection.
