What is a crucial reason for removing keys from a forklift after use?

Removing the keys from a forklift after use is essential mainly to prevent unauthorized use. Leaving the keys in the ignition can significantly increase the risk of the forklift being operated by someone who is untrained or not authorized to do so. This not only enhances the safety of the workplace by reducing the likelihood of accidents but also protects the equipment from potential damage or theft.

While other reasons, such as maintenance checks, cleanliness, and battery conservation, hold importance in a broader context, they do not directly address the critical safety concern of unauthorized operation. Using the forklift without proper training poses risks to operators and other personnel in the vicinity, making key removal a key safety protocol in forklift management.
