Final answer:
Bulk storage bins, containers, and silos must be equipped with safety devices, ventilation systems, and level indicators to ensure safe and efficient operation. All materials, whether in polyethylene, steel, or glass containers, require suitable safety mechanisms and monitoring tools.
Step-by-step explanation:
Bulk storage bins, containers, and silos should be well-equipped to ensure safety and efficiency in material handling. The correct answer to this question is all of the above, which includes: safety devices, ventilation systems, and level indicators. Safety devices are critical to prevent overpressure and under-pressure scenarios. Ventilation systems are necessary to handle the gases or dust that might be emitted from the stored materials. Level indicators are important to monitor the content levels within the containers to prevent overfilling and to manage inventory.
To provide a practical context, imagine using containers in a laboratory or industrial setting. A 1 high-density polyethylene cylindrical container may require different safety devices than a 1 steel cylindrical container or a 1 glass cylindrical container. Each of these might come with a specific set of safety devices suited to the material they are made of and the substances they are meant to store. Regardless of the material, all storage containers should have some form of safety mechanism, proper ventilation, and level monitoring to remain safe and functional.
