When hoisting rails, which of the following statements is correct?

Using a mousing device on the lifting hook of the chain or block is necessary because it prevents the lifting chain or block from accidentally disengaging under load. When hoisting rails or any other heavy objects, ensuring safety is paramount. A mousing device effectively secures the hook and helps maintain control of the load, reducing the risk of accidents. The use of a mousing device is a critical safety procedure in rigging and hoisting operations, aligning with best practices in handling heavy materials.

Additionally, it's essential to recognize that safety measures, such as a mousing device, are often legally required or recommended in many safety regulations. Properly secured lifting equipment increases the overall safety of the operation, protecting both the workers and the equipment from potential hazards.
