What is the first step in using an EWARP patch?

The correct answer is preparing the surface, which is essential to ensure the effectiveness of the EWARP (Emergency Water Activated Repair Patch) when applied. When you prepare the surface, it involves cleaning and drying the area around the leak thoroughly. This is crucial because any dirt, grease, or moisture can hinder the bonding of the patch to the pipe or structure, potentially allowing water to continue leaking and reducing the patch's overall effectiveness.

By making sure the surface is clear and ready for the patch, you enhance the likelihood that the EWARP will adhere properly and create a robust seal, which is vital for controlling leaks in emergency situations. This preparation step lays the foundation for a successful repair, making it a logical first step in the entire patch application process.
