So you've seen these signs (actually called NFPA panels) hundreds or thousands of times, but aside from a vague notion that you shouldn't touch anything behind one, you don't really know what they mean. Here's a quick explanation, and here's something even cooler: a site where you can make custom NFPA signs of your very own. (The price varies, but you can get a reasonably-sized one for $11.) Just pick what you want in the diamonds, enter some explanatory text, and decide whether you want it on aluminum, plastic, a magnet, or what. If you're really creative, you could always opt to leave some of the diamonds blank and fill them in with stickers or stencils of your choice - a broken heart in the "specific hazard" quadrant might be a fair warning to anyone entering your front door.
