Overheating of an uncoiled, heavy-duty extension cord under continuous high load-- What It Can Cause: Electrical insulation melting, short circuits, and severe residential fires starting inside stored gear.-- Solution: Uncoil extension cords fully before powering high-draw tools or space heaters to allow thermal dissipation. And yes, I know the cord in the photo is not the heavy-duty type. Did you already know that you shouldn't keep your extension cord coiled?

Electrocution from an ungrounded wet/dry shop vacuum operating in standing water-- What It Can Cause: Severe electric shock, ventricular fibrillation, and secondary fall injuries.-- Solution: Plug wet/dry vacuums into a Ground Fault Circuit Interrupter (GFCI) outlet whenever operating near liquids. Do you have a wet/dry vac? I do.

Accidental detonation of a residential lawnmower gas tank during hot refueling-- What It Can Cause: Flash fire, third-degree burns over upper body, gasoline splash ignition, and garage fires.-- Solution: Allow outdoor power equipment engines to cool down for at least 10 minutes before adding fresh fuel. Does your home have a lawn that you have to mow?

Inhaling toxic fumes from an overheated PTFE (non-stick) pan in an unventilated kitchen-- What It Can Cause: Polymer fume fever ("Teflon flu") with high fever, chills, chest tightness, and acute respiratory distress.-- Solution: Never preheat non-stick cookware empty on high heat, and always run kitchen exhaust fans when cooking. Have you ever preheated a pan of any type? I do not want to have to admit this, but I have. I won't do it again.

Structural collapse of a heavy wet-snow-laden outdoor shade canopy or pergola-- What It Can Cause: Traumatic head impact injuries, limb fractures, and entrapment under heavy lumber or metal frames.-- Solution: Clear heavy snow accumulation from patio covers and temporary canopies using a roof rake from a safe distance. Do you have a canopy or pergola?

Structural collapse of an old backyard wooden treehouse while occupied-- What It Can Cause: Falls from 10–20 feet, spinal cord injuries, skull fractures, and puncture wounds from splintered timber.-- Solution: Anchor treehouses using specialized tree-house attachment bolts (TABs), inspect supporting tree limbs for decay, and limit occupancy. Did you have a treehouse as a kid? I didn't.
