Shoveling Snow Know your limits when shoveling snow. Rest frequently and pace yourself. If you become breathless, stop, go indoors and warm up before continuing. If you experience chest or arm pain or numbness, stop immediately and go indoors. Do not smoke while you are working.
Smoking constricts the blood vessels.
If you use a snowblower, be sure to have a firm footing before you start it. Remove obstacles from your path and aim the snow carefully. Do not unclog the snowblower chute while the engine is running. It can occur even inside with cool temperatures over a period of time. This condition can be fatal if not detected promptly and treated properly.
