Anyone performing welding or hot work needs to take as many precautions as possible to avoid starting a fire. In a previous blog post, we shared five basic fire safety tips for welders. In this post, we’ll focus a little more closely on clothing and other soft materials.

According to the most recent data from the National Fire Protection Association (NFPA), U.S. fire departments responded to an annual average of 3,396 structure fires caused by welding or hot work between 2017 and 2021. Welding torches were the primary cause cited in the majority of the fires. The good news is that welding and hot work fires are preventable when the right precautions are taken.

Copper tubing is a popular material in cryogenics because of its ductile nature at low temperatures. But copper is not immune to pinholes and cracking due to daily wear-and-tear and weaknesses introduced by contaminants and general exposure to the elements.

Tube fittings probably aren’t something you think about every day, at least, not until something breaks. And when that something breaks, you want to be certain you have the replacements on-hand that can do the job.

A vast majority of problems with DOT-4L liquid cylinders are directly related to customer tampering with the set screws on economizers and pressure-building regulators.
