Can breaking a thermometer lead to mercury poisoning?
Improper handling of a broken mercury thermometer may potentially lead to mercury poisoning, albeit with a very low probability. Mercury thermometers contain a small amount of mercury, which can evaporate at room temperature. Even if a mercury thermometer is broken and handled improperly, it may result in the mercury breaking into smaller droplets, which are more prone to evaporation in higher ambient temperatures. However, if mercury comes into direct contact with a patient's skin, mouth, nose, or other areas, it may enter the body and cause mercury poisoning, manifesting as symptoms such as headaches, fatigue, and fever.
On the other hand, if a thermometer that does not contain mercury is broken or if a broken mercury thermometer is handled properly, followed by prompt ventilation to accelerate air circulation in the room and expel the evaporated mercury outdoors, there is no risk of mercury entering the human body. In such cases, mercury poisoning or other discomforts will not occur. After breaking a mercury thermometer, it is crucial to promptly turn off indoor heating appliances, ensure prolonged ventilation, and use bookmarks, adhesive tape, or other means to collect and seal the spilled mercury for proper disposal, especially keeping it out of reach of children.
