When dealing with a broken thermometer, attention should be paid to strict protection. Mercury thermometers, which are made of glass, are therefore easy to break. After the fall, the mercury, will be scattered to the ground and other parts, if not dealt with in a timely manner, mercury evaporation, the formation of mercury vapor, inhaled by the human body, will lead to mercury poisoning. Therefore, when the mercury thermometer is broken, the mercury should be carefully collected and put into a sealed bottle.
The mercury that can't be completely collected can be sprinkled with some sulfur powder.
