How often should acetylene cylinders be tested for safety?

The correct answer is based on safety regulations established for the handling of acetylene cylinders. According to industry standards and regulations set by organizations such as the Department of Transportation (DOT), acetylene cylinders must be hydrostatically tested every ten years to ensure their integrity and safe operation.

This testing is crucial because acetylene is a highly flammable gas, and the cylinders used to store it are subject to wear and corrosion over time. The hydrostatic test checks for potential leaks, rust, or structural weaknesses that could lead to dangerous failures if a cylinder is mishandled or if there are changes in temperature or pressure during storage and use.

Understanding the importance of this testing interval helps ensure the safety of both the operators and the general public when handling and storing acetylene. Regular testing upholds safety standards, reduces the risk of accidents, and maintains compliance with regulatory requirements.
