Stuck gas pedal / runaway acceleration Action: Shift the transmission into Neutral (N), apply firm and continuous pressure to the brakes (do not pump them), and steer safely to the shoulder before turning off the engine. Do you ever drive a car?

Getting caught in a stampede or dense crowd push Action: Move diagonally across the flow rather than fighting against it. Keep your arms folded across your chest like a boxer to protect your ribs and create breathing space for your lungs. Do you ever go anywhere where there are crowds, like a concert or ball game?

Bitten by a venomous snake Action: Keep the victim calm and still to slow venom circulation. Keep the bite site below heart level. Do not cut the wound, suck out venom, or apply a tourniquet. Don't think this could ever happen to you? I once worked in a factory (in Indiana) and we were unwrapping a group of boxes on a wooden palette. The shipment of parts on the palette were from Texas. Between two of the boxes was a large snake. Also, if you buy things on whatnot or any other auction sites where many things come in a box, watch for dangerous spiders in the box. Do you have venomous snakes where you live?

Water heater pressure relief valve failure (boiling water rocket effect) Action: If you hear violent rattling, loud whistling, or steam coming from the tank, cut the power/gas to the heater from a distance and do not go near the unit. Call a plumber immediately. Do you have a gas or electric water heater?

Sewer gas backup (dry P-traps in unused drains) Action: Methane and hydrogen sulfide can accumulate. Pour a gallon of water down all dry drains/floor traps to re-establish the liquid barrier. Ventilate the room. This can have other causes, such as blocked vent pipes, faulty seals, or damaged sewer lines, so if rehydrating does not work to get rid of the smell, call a plumber Has this ever happened to you?
