SHOVEL. KEEP YOUR GAS TANK FULL...AND AVOID TRAVELING ALONE. LET
SOMEONE KNOW YOUR TIMETABLE AND YOUR PRIMARY ROUTE.

WALK FOR HELP IN A WINTER STORM COULD BE A DEADLY DECISION. RUN
THE MOTOR FOR ABOUT 10 MINUTES EVERY HOUR FOR HEAT. OPEN THE
WINDOW A LITTLE FOR FRESH AIR TO AVOID CARBON MONOXIDE POISONING.
MAKE SURE YOUR EXHAUST PIPE IS NOT BLOCKED FROM ICE AND SNOW.
3. IF YOU NEED TO USE A PORTABLE GENERATOR...FOLLOW MANUFACTURERS
INSTRUCTIONS TO KEEP THE AREA SURROUNDING YOUR GENERATOR WELL
VENTILATED.
4. DO NOT ATTEMPT TO SHOVEL SNOW UNLESS YOU ARE PHYSICALLY FIT.
HYDRATE YOURSELF OFTEN WITH WATER WHILE SHOVELING...AND TAKE
FREQUENT BREAKS.
5. MOVE PETS AND FARM ANIMALS TO SHELTERED LOCATIONS AND ENSURE
THEY HAVE PLENTY OF FOOD AND DRINK.
6. LISTEN TO NOAA WEATHER RADIO...LOCAL AND CABLE OUTLETS TO
