The battery feeds power to ignition switch, so it is important for the ignition system that the battery is in good condition. Don't put too much weight on your key ring because this can damage the key and the tumbler part of the ignition switch.
To maintain food safety, refrigerators should be kept at or below 40 F and freezers should be 0 F. One of the most basic ways to ensure food safety in your kitchen is to set your refrigerator and freezer to safe temperatures for food storage. According to the Food and Drug Administration, your fridge should be set at or below 40 F (4 C). Your freezer should be set at 0 F (-18 C). Food stored in the freezer at 0 F will remain safe indefinitely, although the quality will decrease the longer the food is in the freezer. Freezing does not change a food's nutritional value.
Normally a domestic freezer is best set to â18 Â°C (0 Â°F) or colder, as that's what the expiration dates for many food items are based on. It's also a requirement for freezers in restaurants, supermarkets & other places that sell food (at least here in Europe) to maintain a temperature of at most -18 Â°C.A general purpose domestic fridge should be at around 1-4 Â°C (so, just above the freezing point, and below 5 Â°C).n order to keep food out of the Danger Zone, your fridge must be set between 32-40Â°F (0-4Â°C). Your freezer must be below 32Â°F (0Â°C). I keep mine as cold as it will go.
