How often should jacks be inspected for safety?

Jacks should be inspected before each use or at least once a month if they are used regularly to ensure that they function safely and effectively. Regular inspections are critical in identifying any wear and tear, damage, or malfunctions that could compromise safety during operation.

By conducting inspections frequently, operators can catch potential issues early, ensuring that the jack is in proper working condition and reducing the risk of accidents or failures while lifting loads. This proactive approach to safety not only protects the equipment but also ensures the safety of personnel working around it.

The other options suggest less frequent inspections, which may not adequately address the ongoing wear and tear jacks can experience, especially with regular use, increasing the risk of failure and associated hazards.
