4. All of the above

The correct answer is: All of the above

Before unloading a full tank, it is crucial to undertake several essential actions to ensure safety and compliance with regulations. One vital step involves checking the weather conditions, as adverse weather can create hazardous situations during the unloading process. Awareness of rain, wind, fog, or extreme temperatures can influence how you manage the unloading safely. Inspecting the vehicle for leaks is another critical action. A leak could not only signify a problem with the tank but could also pose severe environmental and safety hazards, such as the risk of a fire or contamination of the surrounding area. Ensuring that the vehicle is in good condition before unloading helps mitigate these risks. Additionally, ensuring the area is clear of pedestrians is imperative for the safety of those in the vicinity. During unloading, there is always the risk of spills or accidents, and having clear access allows you to concentrate on the task without worrying about the safety of others nearby. Consequently, taking all these precautions—assessing the weather, inspecting for leaks, and ensuring a safe area to unload—collectively enhances the safety of the unloading process, making "All of the above" the most appropriate choice.
