Final answer:
It is false that engaging in shock loading is advised when using slings because it can cause abrupt force changes leading to overloading and sling failure.
Step-by-step explanation:
When using slings for lifting, it is false that it is advised to engage in shock loading. Shock loading is the practice of subjecting the sling to a load in a manner that causes an abrupt change in force, which can result in overloading and potential failure of the sling. This practice is hazardous and is typically advised against because it can lead to damage to both the sling and the load, as well as increase the risk of accidents and injuries.
