Along with taking other measures of common sense and thermal dynamic control—packing in ice or dry ice, keeping doors closed as much as possible—wikiHow notes that wrapping your refrigeration units will aid in insulating them from gaining in temperature.< Also recommended? Eating any room-temperature, perishable food within two hours, and—among the best phrases we've written lately—having an "instant barbecue" to save any meats that can't be kept safe. Of course, you should always toss anything you think had even a chance of spoiling, but protecting fully-stocked fridges and freezers can carry your good up to 48 hours.
