After an LP-gas motor/mobile fuel container is installed, how must the container markings be viewed?

The correct choice is that container markings must be viewed with a portable lamp and mirror. This method ensures that the markings are clearly visible and easily readable, particularly in situations where lighting may be insufficient or when the markings are positioned in an area that is difficult to see directly. Using a portable lamp can enhance visibility by providing adequate illumination, while a mirror can help to view markings from angles that might otherwise be hard to access.

Properly visible markings are crucial for safety and compliance, as they provide important information about the contents of the container, such as safety warnings and handling instructions. This practice aligns with safety regulations that require adequate visibility of information to prevent mishandling and ensure safe operation. It promotes awareness of potential hazards associated with LP-gas and aids in the effective management of the equipment.
