What is the second most prevalent hydrogen hazard source and where is it found?

• A. Batteries
• B. Piping leaks
• C. Radioactive iodine
• D. Zinc paint corrosion found in paint, conduit and junction boxes

Answer: (D)

Hydrogen hazards arise from sources that release H2 gas during normal operation or maintenance. The most common source is hydrogen generated during charging of lead-acid batteries. The second most prevalent source comes from corrosion of zinc coatings, such as zinc paint, on electrical equipment. When these zinc-based surfaces in painted areas, conduits, and junction boxes come into contact with moisture, zinc oxidizes and reacts with water to produce hydrogen gas. That’s why zinc paint corrosion found in paint, conduit and junction boxes is identified as the next significant hydrogen source. Radioactive iodine isn’t related to hydrogen generation, and while piping leaks can release hydrogen, they’re less typical contributors than zinc corrosion in electrical environments.
