For a number of reasons, exhaust system work can be dangerous. Always observe the following precautions:
- Support the vehicle securely by using jackstands or equivalent under the frame of the vehicle.
- Wear safety goggles to protect your eyes from metal chips that may fly free while working on the exhaust system.
- If you are using a torch be careful not to come close to any fuel lines.
- Always use the proper tool for the job.
