What is the correct sequence of the hazard control steps?

1. Educate personnel, guard hazard, engineer out hazard

2. Engineer out hazard, guard hazard, educate personnel

3. Guard hazard, educate personnel, engineer out hazard

4. Engineer out hazard, educate personnel, guard hazard

The correct answer is: Engineer out hazard, guard hazard, educate personnel

The correct sequence of the hazard control steps begins with engineering out the hazard, addressing the root of the problem first. This step aims to eliminate the hazard at its source, which is the most effective way to ensure safety in the workplace. By redesigning processes or using safer materials, the risk associated with the hazard is significantly reduced or completely removed. Following this, the next step is to guard the hazard. This involves implementing barriers, safety devices, or other physical controls that can protect employees from harm when the hazard cannot be entirely eliminated. Guards serve as an important line of defense to minimize the chances of an incident occurring. Lastly, educating personnel is essential to ensure everyone is aware of the hazards present and understands the controls established to mitigate risks. Training and awareness promote a culture of safety and empower employees to recognize potential hazards and respond correctly. Therefore, the correct sequence—engineering out the hazard, guarding it, and educating personnel—reflects a strategic approach to hazard control that prioritizes elimination first, followed by protection measures and finally, training to maintain awareness and compliance.
