What type of control is achieved by confining work operations?

The type of control achieved by confining work operations is best described as engineering control. This form of control involves altering the physical environment or the process itself to eliminate or reduce exposure to hazards. By confining work operations, hazards can be isolated, which minimizes employee exposure to risks associated with those operations. For example, using barriers, physical enclosures, or ventilation systems are all engineering controls that effectively contain hazardous equipment or substances and protect workers.

In contrast, administrative controls focus on changing work policies or procedures to reduce risk, such as implementing training programs or work rest schedules. Behavioral control emphasizes modifying worker behaviors and practices, often through training or awareness campaigns. Personal Protective Equipment (PPE) includes items like gloves, helmets, or eye protection that workers wear to protect themselves but do not inherently change the hazard itself. Thus, engineering control stands out as the method that directly manipulates the work environment to mitigate hazards.
