Which of the following is essential before operating a forklift?

Before operating a forklift, reviewing the cargo weight is essential because it directly affects the safety and stability of the lift. Forklifts have specific load capacities, and understanding the weight of the load being handled is crucial to prevent tipping or accidents. Proper weight assessment ensures that the forklift is not overloaded, which can lead to loss of control, damage to the equipment, or injury to personnel in the vicinity.

Ensuring comfort of the seat, adjusting the radio, and checking weather conditions are less critical factors in the immediate operation of a forklift. While they contribute to overall operator satisfaction and safety, they do not impact the fundamental safety requirements of load handling as significantly as understanding the cargo weight does. Therefore, prioritizing the review of cargo weight aligns with best safety practices in forklift operation.
