What should be done if a blade is found to be cracked during inspection?

When a blade is found to be cracked during inspection, it is crucial to prioritize safety and the integrity of the equipment. Putting the blade out of service immediately is the correct course of action because a cracked blade poses significant risks during operation. Continuing to use a damaged blade could lead to catastrophic failure while in use, which could potentially cause serious injury to the user or others nearby, as well as property damage.

Additionally, repairing a cracked blade may not effectively restore its original strength or safety unless performed by qualified personnel, and thus may not be a reliable option. Marking the blade for future inspection does not adequately address the immediate safety concern posed by the crack, and using it under such conditions could further deteriorate the blade or lead to an accident. Therefore, removing the blade from service ensures that it cannot be used until a thorough assessment and proper remedial action are taken.
