Yeah I've done that and it always feels rewarding whenever you do. You just have to stand by a commonly used Thermite/Hibanna charge wall and as soon as you hear someone walk up to the door, you throw the claw. You throw the claw as soon as you hear them because Thermite's Exothermic Charges deploy faster than Kaid's Claw. But if you keep in mind that Thermite is still approaching the wall and still has to set/activate the charge, then Kaid's Claw can destroy Thermite's charge mid-run.
