The correct sequence of hazard control methods is based on the hierarchy of controls, which prioritizes strategies for managing hazards. The sequence typically starts with engineering controls, which are designed to eliminate or minimize the hazards at their source.

In this case, "engineer" is placed first in the sequence, highlighting the focus on designing safer systems, machines, or processes that inherently reduce risks. This could involve modifications to equipment or changes in workflow to eliminate exposure to hazards.

Following engineering controls, "guard" comes next. This step involves putting physical barriers or protective measures in place to separate workers from hazards when engineering controls cannot fully eliminate them. Examples include safety guards on machinery or barriers to protect workers from falling objects.

Finally, "educate" is the last method in this sequence. Training and educating employees about the hazards they may encounter, safe work practices, and the proper use of personal protective equipment add an essential layer of safety awareness. However, education alone does not eliminate hazards; thus, it is considered a last step after implementing more effective controls.

This sequence underscores the importance of prioritizing engineering solutions first, followed by physical safeguards, and lastly focusing on employee education. This approach is grounded in safety best practices, aiming to create the most effective environment for
