What are the responsibilities of the Occupational Safety Division (OSD)?

The Occupational Safety Division (OSD) is responsible for a range of essential functions that contribute to the health and safety of employees in the workplace. Each of the listed options represents a critical component of the OSD's responsibilities.

Tracking verified exposure incidents is crucial as it helps identify patterns of exposure to hazardous substances and informs strategies to minimize risks. Processing source-testing requests is equally important, as it ensures that any potential health risks related to exposure can be adequately assessed and mitigated. Offering hepatitis B virus (HBV) vaccinations to employees is another vital responsibility, as it plays a proactive role in protecting employee health against infectious diseases.

Since these functions collectively enhance occupational safety and health, the comprehensive nature of these responsibilities reinforces that the correct answer encompasses all these facets. Thus, the answer underscoring that the OSD manages a broader range of health and safety initiatives is justified.
