Which of the following is NOT listed as a potential eye hazard in the workplace?

The choice identifying "organic" as not being listed as a potential eye hazard in the workplace is accurate because "organic" typically refers to substances derived from living organisms. While organic materials can pose various hazards, they are not classified as a direct eye hazard in the context of workplace safety.

In contrast, strain refers to the fatigue or discomfort that can arise from prolonged use of the eyes, particularly when using computers or focusing intently on tasks. Impact hazards involve the risk of physical objects striking the eye, which can lead to serious injuries. Heat hazards, such as sparks or hot materials, can also pose threats by potentially causing burns or other eye damage. Therefore, the other options represent specific physical risks to the eyes, whereas "organic" does not fit within the established categories of eye hazards that are commonly recognized in workplace safety protocols.
