AWS Certified Welding Inspector — FundamentalsSafetyEasy

A welding inspector is conducting a safety audit in a fabrication shop where several oxy-fuel cutting operations are taking place. The inspector observes multiple oxygen and acetylene cylinders stored upright, but some are chained together, while others are simply leaning against a wall. What is the most critical safety violation observed regarding cylinder storage?

  1. AThe oxygen and acetylene cylinders are stored too close to each other.
  2. BSome cylinders are not properly secured to prevent falling.
  3. CThe cylinders are stored upright instead of horizontally.
  4. DThere is no clear signage indicating the contents of each cylinder.
Show answer & explanation

Correct answer: B. Some cylinders are not properly secured to prevent falling.

Compressed gas cylinders must always be secured, typically by chaining or strapping them to a wall or a cylinder cart, to prevent them from falling over, which could damage the valve and cause a rapid release of gas, turning the cylinder into a dangerous projectile.

Why the other options are wrong

  • A. While a separation distance is often recommended for full and empty cylinders or different gas types, the immediate danger of falling is more critical.
  • C. Most compressed gas cylinders are designed and intended to be stored upright, not horizontally, to prevent liquid withdrawal or valve damage.
  • D. Clear labeling is important for identification, but the physical hazard of an unsecured cylinder falling is more immediate and severe.

Compressed Gas Cylinder Securing

Compressed gas cylinders must always be secured in an upright position with chains, straps, or other approved methods to prevent them from falling over, which can lead to valve damage and uncontrolled gas release.

  • Falling cylinders can become dangerous projectiles.
  • Valve damage can cause rapid gas release.
  • Securing prevents property damage and serious injury.
  • Chains or straps are common securing methods.

Memory trick: Secure Your Cylinder: Don't let it fall or it'll fly!
