What is the proper way to handle the boom to prevent damage?

The proper handling of a boom to prevent damage involves using the appropriate rigging techniques. Attaching the sling to the lifting lugs, if present, is essential because these lugs are specifically designed to bear the load and distribute weight evenly. This helps in maintaining the integrity of the boom, minimizing the risk of bending or breaking during operations.

Using a sling on lifting lugs ensures that the load is securely fastened and that the weight is managed in a way that adheres to the manufacturer's specifications. This practice is crucial for ensuring safety, as it not only protects the equipment but also safeguards the operators and personnel nearby from potential hazards associated with improper rigging.

The other options involve practices that could compromise the safety and integrity of the lifting operation. Leaving the boom unsecured poses significant risks as it could shift unexpectedly. Non-standard lifting ropes may lack the necessary strength and durability for safe lifting, leading to potential failure. Overloading the boom while lifting directly contradicts safe lifting practices, as it may result in mechanical failure or damage.
