  • Sulfur hexafluoride - Wikipedia

    Like xenon, sulfur hexafluoride is a nontoxic gas, but by displacing oxygen in the lungs, it also carries the risk of asphyxia if too much is inhaled. Since it is more dense than air, a substantial quantity of gas, when released, will settle in low-lying areas and present a significant risk of asphyxiation if the area is entered.

  • 10 Tips for Getting the Most Out of an Optical Gas Imaging

    Understand the application and the need. Different applications require different cameras. In other words: one camera may not see all the gases, so you need to understand which type of gas you are dealing with. Take the environment into account. The success of OGI depends on environmental conditions. The greater the background energy differential, the easier the camera will be able to visualize the gas leak and pinpoint its source. Remember: OGI is qualitative, not quantitative.* Due to the environmental variants and the background energy differential and variations, an OGI camera alone cannot determine the specific type or amount of gas escaping through a leak. Use all the features of your OGI camera. Learn how each feature of the OGI camera works - such as automatic GPS tagging or image enhancements - and use them to your advantage.
