Need safety tips for cutting corrugated metal roofing with a circular saw

Hey folks, DIY dad here with a weekend project gone sideways. I'm trying to cut some old corrugated metal roofing panels for a shed repair, using my circular saw with a metal-cutting blade. Did a test cut and it was LOUD and threw sparks everywhere - my wife's freaking out about fire risk. What's the safe way to do this without losing fingers or burning down the garage? Should I be using a different attachment or technique? Appreciate any tips!

Rick, you're lucky you didn't get a face full of hot metal shards. NEVER use a standard circular saw setup for corrugated metal without proper prep. First, clamp that panel down SECURELY - vibration will make it walk right into you. Second, wear a full face shield, leather gloves, and fire-resistant clothing. Those sparks can ignite sawdust or fluids in seconds. For cleaner cuts with less sparking, consider a nibbler attachment or a jigsaw with metal blade. And keep a fire extinguisher within arm's reach - not kidding.

Greg's spot on about the fire risk. As a sparky, I've seen too many workshop fires from metal cutting. Make sure there's NO electrical cords or flammable liquids nearby. Also, check your saw's grounding - metal dust can short things out fast. If you must use the circular saw, go SLOW with steady pressure. The blade will dull quick on that corrugated stuff, so have extras ready. Personally, I'd use my angle grinder with a cutoff wheel for more control, but that's just me.

Landscape architect here - we deal with corrugated metal for garden sheds and structures all the time. For occasional DIY use, try scoring the cut line with a utility knife first (wear cut-resistant gloves!), then use aviation snips for the final separation. Much quieter, no sparks, and way safer if you're not experienced with power tools on metal. If you're set on power tools, Home Depot rents metal-cutting chop saws that are way more controlled than a circular saw. Your neighbors will thank you for the noise reduction too!
