According to safety measures, how should materials be moved to prevent hazards?

Ensuring proper rigging is in place is critical for moving materials safely to prevent hazards. Rigging refers to the equipment and techniques used to lift, lower, or move heavy objects. Proper rigging involves using the right type of rigging gear, ensuring it is in good condition, calculating load limits, and securing the load properly before moving it. This not only helps in preventing accidents but also in ensuring the safety of all workers in the vicinity, as loose or improperly secured materials can pose serious risks during transportation.

While the other options involve important safety practices, they do not address the specific need for rigging in the context of moving materials. Gloves can protect hands from sharp edges or chemicals, multiple workers can provide additional strength or support, and mechanical aids can reduce physical strain. However, without proper rigging, the safety of lifting and moving heavy or awkward loads cannot be guaranteed, making it the most essential factor in preventing hazards during material handling.
