Which statement describes the zinc paint hazard source?

• A. The second most prevalent source is zinc paint corrosion found in paint, conduit and junction boxes
• B. Battery corrosion is the second most prevalent source
• C. Piping corrosion is the second most prevalent source
• D. Radioactive iodine is the second most prevalent source

Answer: (A)

Zinc-containing coatings are widely used on plant surfaces—paint, conduit, and junction boxes—so as the coatings age and corrode, zinc compounds can be released and become a common, ongoing hazard source. This ubiquity across many components makes zinc paint corrosion a frequent contributor to hazard exposure, more so than the other listed sources in the typical hazard-source rankings used in these questions. While battery corrosion, piping corrosion, and radioactive iodine can pose hazards, they don’t show up as consistently across the plant’s coated surfaces in the same way zinc paint does, which is why the statement about zinc paint being the second most prevalent source best fits the scenario.
