The correct choice focuses on a type of hazard that specifically involves toxins that can enter the bloodstream and impact vital organs. The term "Ocular Hazard" refers to risks associated with exposure to harmful substances that can affect the eyes. However, when considering substances that can infiltrate the bloodstream and have broader systemic effects, the classification may not align with ocular hazards.

In contrast, Neurotoxic Hazards accurately describes substances that can cause damage to the nervous system, which includes the potential for systemic effects as toxins enter the bloodstream. This categorization is crucial in occupational health and safety, as neurotoxins can have significant implications on overall health.

It is essential to understand how these different hazards correlate with exposures within a workplace. Cutaneous hazards, for example, relate to skin contact, while respiratory hazards pertain to inhalation. Yet neither of these categories covers the bloodstream and organ effects as comprehensively as neurotoxic hazards do.
