Some people use mercury thermometers to measure body temperature at the moment, accidentally broke the thermometer, the mercury out of it. The mercury of the thermometer is a toxic liquid metal, if the thermometer is accidentally broken by us will be poisoned? So many people control panic. Don’t panic, don’t worry, these dispositions to solve your questions, below, and career knowledge to see it together.
Mercury thermometer broken toxic?
Mercury is commonly known as mercury, silver-white liquid metal, with aggressive and health hazards. Thermometer broken, the concentration of mercury in the room can exceed the standard several times, and even lead to mercury poisoning.
At room temperature, mercury will evaporate, a short time to inhale a large amount of mercury vapor, before the possibility of mercury poisoning, as usually shown as fever, dizziness, headache and other symptoms, accompanied by inflammation of the mouth, gastroenteritis, serious damage to the lungs, kidneys, central nervous system. Mercury is indeed a potentially harmful heavy metal, the harm is mainly the mercury vapor after volatilization, but as long as the real-time disposal is suitable, there will be no significant impact. Therefore, there is no need to panic too much.
Mercury thermometer broken how to do
1, the mercury thermometer broke, can not use napkins and other simple wipe, but immediately open the window ventilation, real-time finishing, to accelerate the spread of mercury vapor. As usual, as long as it is not direct contact, a mercury thermometer is not too dangerous.
2, in case of accidentally broken mercury thermometer, for the small mercury beads on the ground, available small shovel, syringe, wet cotton swabs and other networks up, do not throw away. If the mercury enters the body, or there are symptoms of mercury poisoning, it must be sent to the hospital immediately for treatment.
3, thermometer broken the best disposal facility is to sprinkle some sulfur powder on the mercury, so that the mercury will be chemically reflected, and the sulfur in the sulfur powder is connected, forming a basaltic lump mercury sulfide.
4, if there is no sulfur powder, can also be used rubber-tipped dropper to draw the mercury into the tube, together with the dropper buried deep into the soil, so that the mercury will not volatilize out, can not be directly dumped into the sewer or dumped into the garbage with other garbage.
The thermometer broke the mercury can not find how to do
Open doors and windows to the wind, so that the mercury evaporates with the wind, while only the ground is organized and cleaned. Do not touch it with your hands, because mercury is highly toxic. After sweeping and organizing do not care about the mercury you can not find, because the mercury will evaporate, so that after a while he will evaporate clean. However, to ensure that the room is moderately ventilated, because the volatile mercury is also toxic Oh. The room where the mercury is leaking should be separated from other rooms to maintain the best ventilation conditions in the room where the mercury is leaking, and if possible, raise the temperature of the room. If other rooms are also inhabited, it is best to maintain excellent ventilation conditions.
Thermometer broken hands touch the mercury how to do
Liquid mercury is basically non-toxic, inadvertent skin contact will not cause any special danger. And liquid mercury only under direct ultraviolet light will turn the table into highly toxic mercury vapor, so as long as it is not a long time to play mercury in the outdoor sunlight, there is basically no risk of mercury poisoning.
If it is just a little contact, as usual, it is fine. It is recommended to apply some milk on top of the skin, partially wash off with water, and examine a few days without anything to do. Then, the last two days to intimately examine the transformation of the body situation, there are problems in real time to contact the doctor.
Swallowing mercury by mistake can gulp milk
As usual, the supplies contain mostly metallic mercury, and the content is very small, even into the body will not be absorbed by the digestive tract, less than a few hours, more than a dozen hours, can be dumped from the feces. If you accidentally swallow mercury, you should be sent to the hospital immediately, and a lot of milk or egg whites, so that the albumen and mercury linked to cherish the stomach mucosa. If the wound touches the mercury, you should also go to the hospital’s poison control department for examination and treatment after the signs of poisoning.
The way to use mercury thermometer
It is very important to use the thermometer accurately to prevent mercury poisoning from breaking the thermometer and to maintain the accuracy of the thermometer temperature. The measurement of body temperature is usually commonly used in 3 parts, namely the mouth, armpit and anus.
1, the armpit measurement method. We will first mercury thermometer degree dumped to 35 ℃ or less, and then the mercury end of the thermometer placed in the armpit after the top of the clamp. Make sure that the thermometer and the skin warm contact, almost 5 minutes after removing the thermometer. After taking a good reading, wipe it with a piece of paper to clean it for the next use. The armpits are prone to sweating, so be sure to wipe the sweat under the armpits first when measuring. The axillary temperature measurement should pay attention to the time to control between 5-6 minutes.
2, oral measurement method. First, the mercury thermometer degree dumped to 35 ℃ or less, the thermometer placed under the tongue slightly with a little force pressure. Before that, you must remember to disinfect the outside of the thermometer and wipe it clean before putting it in the mouth. The time is 3 minutes, remember not to speak in the center. The moment of measuring the mouth pay attention not to bite too hard thermometer, if broken will have the risk of poisoning. Unconscious patients and children are best not to use this measurement method. Oral temperature measurement is completed as usual, wipe clean with a tissue, and then wipe the entire mercury thermometer with an alcohol cotton ball and put it back in place for the next time.
3, anal measurement method. Usually used for fainting patients or small children, the patient supine, the head of the anal table lubricated with oil, gradually inserted into the anus, deep to the anal table until 1/2, placed 3 minutes after reading.
The human body temperature in a healthy state is usually relatively constant, that is, it is maintained at 37 ℃ or less (roughly 36.2 ℃ ~ 37.3 ℃), and will not change due to changes in the external environment temperature. Then for most normal people, the oral body temperature is limited to 36.7 ℃ to 37.7 ℃, the axillary temperature is limited to 36.0 ℃ to 37.4 ℃, and the rectal temperature is limited to 36.9 ℃ to 37.9 ℃.
The body temperature of a normal human being fluctuates slightly within 24 hours, and as usual does not exceed 1 ℃. In the psychological case, it is slightly lower in the morning and slightly higher in the daytime or after exercise and eating. The body temperature is slightly lower in the twilight years and slightly higher in women before menstruation or during pregnancy. It is common for women to take their body temperature every day to check their basal body temperature during pregnancy preparation.
