Mercury Thermometer Range

How to use a mercury thermometer to see if it is a fever range?A normal body temperature is typically around 98.6 degrees Fahrenheit (37 degrees Celsius), but a range of 97-99 degrees Fahrenheit (36.1-37.2 degrees Celsius) is considered normal. If the temperature reads above 100.4 degrees Fahrenheit (38 degrees Celsius), it is considered a fever and medical attention may be needed.

Why dump before using a mercury thermometer?

1. Safety concerns: Mercury is a toxic substance that can cause health hazards if inhaled or ingested. If a mercury thermometer breaks, the mercury can spread and contaminate the surroundings. Therefore, to avoid any potential harm, mercury thermometers should be thoroughly checked for cracks and should be disposed of properly if they are broken.

2. Accuracy: Mercury thermometers should be dumped before use to eliminate any air bubbles that may have entered the thermometer. The air bubbles can cause the readings to be inaccurate.

3. Calibration: Dumping a mercury thermometer before use can help calibrate the thermometer to ensure that it is working correctly.

4. Hygiene: Mercury thermometers should be wiped with alcohol before use to prevent any contamination. Dumping the thermometer before use ensures that any dirt or debris is removed before use.
