Welding near water storage tanks is safe.

• A. True
• B. False
• C. Sometimes
• D. Not sure

Answer: (B)

Welding near water storage tanks is not safe because the area can contain flammable vapors or liquids that can be ignited by sparks or hot metal. Even if a tank looks empty, vapors may still be present, or they can accumulate in spaces and be ignitable when mixed with air. Moisture from water and rain also raises the risk of electrical shock and equipment faults during welding, since moisture conducts electricity and can create hazardous conditions for the welder and nearby personnel. In practice, hot work near tanks requires strict controls—testing the atmosphere for flammable gases, removing or isolating flammable materials, using a fire watch with extinguishing equipment, ensuring proper grounding and insulating clearances, and following a formal hot-work permit process—before any welding is attempted. Without these precautions, welding near water storage tanks remains unsafe.
