Introduction

In general, whether mercury from a broken thermometer can cause poisoning depends on how it is handled. If proper measures are promptly taken and the room is well ventilated, poisoning may not occur. However, if appropriate actions are not taken promptly and ventilation is poor, mercury exposure may lead to poisoning. If any symptoms of discomfort arise, it is recommended to seek medical attention promptly and receive standardized treatment under a doctor's guidance.

Generally speaking, whether breaking a mercury thermometer can cause poisoning depends on how the situation is handled. If proper measures are promptly taken and indoor ventilation is maintained, poisoning may be avoided. However, if correct procedures are not followed promptly and ventilation is poor, poisoning may occur. If any discomfort symptoms appear, it is recommended to seek medical attention immediately. The detailed analysis is as follows:

Mercury is a silvery-white metal that remains liquid at room temperature and is volatile. When mercury vaporizes, it becomes highly toxic and can enter the body through the respiratory tract, skin, or digestive system, leading to poisoning. The amount of mercury in a thermometer is relatively small; therefore, if appropriate cleanup steps are taken promptly and good indoor ventilation is ensured, immediate poisoning usually does not occur.

However, if spilled mercury is not cleaned up promptly and effectively, mercury vapor may quickly evaporate and spread throughout the room, increasing the risk of poisoning. This is especially true in small indoor spaces with poor ventilation, where mercury vapor concentration can rapidly rise to levels harmful to human health.

If symptoms of poisoning appear or poisoning is suspected, it is advisable to seek medical care immediately and inform the doctor of the exposure details.

What are the methods for using mercury thermometers?

Under normal circumstances, the use of mercury thermometers can be divided into several steps: preparation and disinfection, shaking down to the lowest point, selecting the measurement site, properly placing the thermometer, and reading the temperature. Extra caution should be exercised when using mercury thermometers to avoid breakage, which may lead to mercury leakage. If a thermometer is accidentally broken, immediately open windows for ventilation, wear gloves, and use tools such as cardboard or cotton swabs to carefully collect the mercury.

Can bleach disinfect a thermometer?

Under normal circumstances, bleach is not recommended for disinfecting thermometers. Thermometers are precision medical devices, and their disinfection must follow specific guidelines and standards to ensure accuracy and safety. Bleach primarily contains sodium hypochlorite, which has strong oxidizing and corrosive properties. It is recommended to use specialized medical disinfectants or follow established disinfection protocols for medical devices.

How does a thermometer measure body temperature?

Under normal circumstances, methods for measuring body temperature with a thermometer include axillary measurement, oral measurement, rectal measurement, post-auricular (behind the ear) measurement, and forehead temperature measurement. If body temperature rises, it is recommended to seek medical attention promptly and receive appropriate treatment under a doctor's guidance. It is advised to remain calm during measurement, avoid strenuous activity and emotional fluctuations, and conduct the measurement in a comfortable, quiet environment with suitable room temperature.

What temperature is considered a fever

Fever refers to an elevated body temperature. The determination of fever depends on the measurement site. If measured under the armpit (axillary temperature), a temperature above 37°C is generally considered a fever. If measured orally (oral temperature), a temperature above 37.3°C is generally considered a fever. If measured rectally (rectal temperature), a temperature above 37.7°C is classified as a fever.

Can infants take a bath at night?

In general, infants can take a bath in the evening. When bathing in the evening, make sure to close doors and windows in advance, and maintain the room temperature between 24-28℃ to prevent the infant from catching a chill. The water temperature should be controlled between 37-40℃, and can be accurately measured using a bath thermometer. The duration of the bath should not exceed 10 minutes to avoid excessive physical exhaustion for the infant. After bathing, quickly wrap and dry the infant with a soft towel.
