NIOSH Hierarchy of Control Quiz

What is the most effective control measure in the NIOSH Hierarchy of Control?

• Elimination

• Engineering Controls

• Administrative Controls

• Substitution

What does the substitution level of the hierarchy involve?

• Replacing noisy equipment with quieter models

• Scheduling noisy tasks for times when fewer workers are present

• Using earplugs or earmuffs to protect the worker's hearing

• Implementing quieter technology or processes

What are examples of engineering controls for noise hazards?

• Limiting the time workers spend in noisy areas

• Scheduling noisy tasks for times when fewer workers are present

• Using quieter equipment or processes

• Sound enclosures, barriers, or mufflers on machinery

What is the focus of administrative controls in the hierarchy?

• Replacing noisy equipment with quieter models

• Using earplugs or earmuffs to protect the worker's hearing

• Changing work practices and procedures to reduce exposure to the hazard

• Implementing quieter technology or processes

When should personal protective equipment (PPE) be used according to the hierarchy?

• As the first line of defense against hazards

• As a last resort when other methods are not feasible or sufficient

• After implementing engineering controls

• Before exploring alternatives to reduce noise

What is the goal of using the NIOSH Hierarchy of Control?

• To create a noisier work environment

• To protect workers more effectively

• To rely solely on personal protective equipment

• To eliminate the need for control measures

What is an example of elimination of a noise hazard?

• Using quieter equipment or processes

• Completely removing the hazard from the workplace

• Replacing noisy equipment with quieter models

• Scheduling noisy tasks for times when fewer workers are present

What is the least effective control measure in the hierarchy?

• Substitution

• Engineering Controls

• Personal Protective Equipment (PPE)

• Administrative Controls

What is an example of a substitution for a noise hazard?

• Completely removing the hazard from the workplace

• Scheduling noisy tasks for times when fewer workers are present

• Replacing noisy equipment with quieter models

• Using quieter equipment or processes

What should be the approach when applying the NIOSH Hierarchy of Control?

• Eliminate the need for control measures altogether

• Rely solely on administrative controls to reduce exposure to hazards

• Use personal protective equipment (PPE) as the first line of defense

• Use the most effective control measures at the highest level of the hierarchy before resorting to lower-level controls like PPE
