When operating a hand-throw switch, which of the following is required?

When operating a hand-throw switch, being careful of obstructions is essential for ensuring safety and preventing accidents. This involves checking the area around the switch to make sure that there are no materials, tools, or other obstructions that could interfere with the switch operation. It is also important to ensure that the switch lever can move freely without obstruction, which is crucial for the proper and timely operation of the switch.

This caution helps prevent hazards, such as the switch not being thrown correctly or unintended movement of trains. By maintaining awareness of one's surroundings and ensuring a clear workspace, operators can enhance safety for themselves and the entire railway operation, thereby supporting overall operational efficiency.
