Types of OSHA violations can include all of the following except:

The categorization of OSHA violations typically includes serious, other-than-serious, and willful violations. Each of these has specific definitions and implications for workplace safety.

Serious violations occur when there is a substantial probability that death or serious physical harm could result from a condition that the employer knew or should have known about. Other-than-serious violations are those that are not serious but still relate to job safety and health. A willful violation suggests that the employer intentionally disregarded the safety regulations or acted with plain indifference to employee safety.

Imminent danger, on the other hand, is not classified as a type of violation in the conventional sense but rather indicates a situation that poses an immediate risk of death or serious physical harm to employees. While it is a crucial concept in safety inspections and responses, it does not fall under the established categories of OSHA violations. Thus, the correct answer highlights a situation that is more about immediate risk rather than categorizing a violation after the fact.
