What to do if crashed thermometer in the apartment?
you can find a house or apartment where there is no thermometer for measuring body temperature - an indispensable tool for every ailment. And, for the most part, the houses in the post - Soviet space-mercury thermometers. Electronic and infrared temperature gauges, though there are in the market for quite a long time, their old fellow squeezed they are quite slow.
Older people are sceptical about innovation and believe that only mercury thermometer can measure temperature, and the younger generation enjoys the fact that they got in the inheritance and changes the thermometer on modern only when mercury is broken... (by the way, you can read what to do if this happened).
safety Rules when using a mercury thermometer
mercury thermometer has long been treated carefully, knowing that to break it is impossible, because inside is a very dangerous substance (mercury). But the thermometers I and to be informed with the list of actions that need to be done in this situation means to be ready to overcome it with minimal consequences.
first you need to learn the main rules for the treatment of mercury thermometer, which minimize the probability of breakage:
the- First and foremost: the thermometer is not a toy. Children it in no event it is impossible to give even just to hold in your hands;
- Mercury thermometer should be kept in a durable carrying case, usually plastic, in the place where children do not have access;
- «Whipping» thermometer, be extremely careful. Do not touch it with wet hands and stand away from solid objects. This will avoid slipping and accidental impact;
- Measure the temperature of the child only under his supervision. Try yourself to hold the arm of the patient, as children are known for their restlessness and forgetfulness.
dangerous Than a broken thermometer?
Mercury, which measure the temperature, is an 80 element of the periodic table and refers to the first class of danger, representing a cumulative poison. This metal, which is in the range of -39 - +357 degrees Celsius is in a liquid state. That is the only metal which at room temperature is in solid and in liquid form. It is already at 18 degrees, the mercury begins to evaporate, releasing very toxic gases. And this fact makes a broken thermometer is extremely dangerous event.
the Amount of mercury in a conventional thermometer is around 2-5 grams. If all of the mercury will evaporate in a room of 18-20 square meters, the concentration of mercury vapor in the room will be about 100 mg per cubic meter. And it is 300 thousand times more than maximum permissible concentration for residential areas, as against the standard indicators of mercury levels in residential areas should not exceed of 0.0003 milligrams per cubic meter. Of course, this is more theoretical calculations. Natural ventilation of the rooms to such excess will never lead, and to evaporate all the mercury you need a very high temperature. But without proper action a broken thermometer will lead to excessive concentrations of mercury vapor is 50 to 100 times, that is very, very dangerous.
you Need to mention the fact that mercury tends to accumulate in the body. That is, not gathered it carefully, the consequences from inhalation of mercury vapor may occur in a few weeks when you have forgotten that broke the thermometer. In this case, diagnosis of the causes of sickness will be greatly hampered.
