What is an essential part of a railcar's safety protocol during loading?

Securing and blocking cargo properly is crucial in a railcar's safety protocol during loading. This practice ensures that the load remains stable and does not shift during transport, which could lead to accidents or damage to the cargo and railcar. Proper blocking and securing minimize the risk of derailments, cargo spills, or injuries to workers during loading and unloading processes. It also plays a key role in maintaining the integrity of the cargo, ensuring that it arrives at its destination in the condition it was loaded.

While other aspects like checking for corrosion and confirming the weight are important for overall railcar maintenance and operational efficiency, they do not directly address the immediate safety concerns related to cargo stability during loading. Regular cleaning of the railcar's exterior does not impact the loading process or cargo safety directly, making securing cargo the priority in safety protocols.
