What is an important consideration when preparing a pipe for repair?

When preparing a pipe for repair, ensuring that it has no pressure is critical. This means that the pipe must be depressurized before any work is done on it to prevent accidents or injuries. If the pipe remains under pressure, there is a risk of hot water, steam, or hazardous materials being released unexpectedly, which can pose a danger to personnel and complicate the repair process. Furthermore, working on a pressurized pipe can lead to damage of tools and potential failure of the repair itself. Therefore, depressurizing the pipe is a fundamental safety measure that ensures a safer and more manageable repair scenario.
