Quick Answer
Check for a steady, low-level hiss or whine coming from the generator's exhaust pipe, as this can indicate a CO leak. Look for signs of staining or corrosion on the generator's casing or exhaust system. Use a CO detector or a gas leak detector to confirm the presence of CO.
Visual Inspection
Inspect the generator’s exhaust system, including the muffler, tailpipe, and any connections, for signs of staining, rust, or corrosion. Check for any holes, cracks, or damage to the exhaust system that could cause CO to escape. Use a flashlight to illuminate any dark areas around the generator.
CO Detector Testing
Use a CO detector or a gas leak detector to confirm the presence of CO near the generator. Place the detector near the generator’s exhaust pipe, ideally 3-5 feet away, and check for any readings of CO. Follow the manufacturer’s instructions for proper use and calibration of the detector. A CO reading of 10-30 ppm is considered safe, while readings above 100 ppm indicate a potential hazard.
Generator Maintenance
Regularly maintain your generator to prevent CO leaks. Check the oil and air filters monthly, and replace them as needed. Clean the generator’s exhaust system annually, and inspect it for damage or wear. Follow the manufacturer’s recommended maintenance schedule to ensure your generator runs safely and efficiently. Regular maintenance can help prevent CO leaks and ensure your generator operates within safe CO levels.
