In this article, we'll find out what causes rip currents, how you can recognize them and what you should do if one takes you out to sea. A rip current is a narrow, powerful current of water running perpendicular to the beach, out into the ocean. These currents may extend 200 to 2,500 feet (61 to 762 m) lengthwise, but they are typically less than 30 feet (9 m) wide. Rip currents can move at a pretty good speed, often 5 miles per hour (8 kph) or faster.

Best Answer: Safe Refrigerator Temperature For safety, it is important to verify the temperature of the refrigerator. Refrigerators should be set to maintain a temperature of 40 Â°F or below. An appliance thermometer can be kept in the refrigerator to monitor the temperature.This can be critical in the event of a power outage. When the power goes back on, if the refrigerator is still 40 Â°F, the food is safe.Foods held at temperatures above 40 Â°F for more than 2 hours should not be consumed.Appliance thermometers are specifically designed to provide accuracy at cold temperatures.hen the power goes back on, if the refrigerator is still 40 Â°F, the food is safe.
