What should be prominently posted in gas container storage areas?

In gas container storage areas, it is crucial to have clear labeling to ensure safety and proper identification of the substances stored. Posting the names of the gases helps in informing personnel about the specific types of gases present, allowing for the correct handling and emergency responses if necessary. Proper identification is essential during emergency situations, where firefighters and emergency personnel need to know what substances they might be dealing with.

Furthermore, having the names clearly posted can help ensure that those who work in or around the area are aware of specific hazards associated with each gas, which can include flammability, toxicity, and reactivity. This promotes a safer environment by minimizing the risk of accidents due to misidentification or mishandling of gas containers.

The other options, while they may contain relevant information or serve important purposes, do not directly address the necessity of identifying the specific gases stored, which is fundamental for safety protocols in gas storage areas.
