Never, they are still legally available to purchase in the United States. If you are asking this from outside the US, I cannot help you.
For those who are interested in the world outside the USA,
mercury thermometers were directed to be banned, at least for medical use,
in the EU in 2009, and bans were definitely implemented by these countries:
Austria
Bulgaria
Denmark
Italy
Estonia
Latvia
Lithuania
Poland
Portugal
Romania
Slovakia
Spain
Sweden
In the EU, only the Czech Republic has stated it's intention not to implement the ban, while most other EU countries are believed to be in the process of joining the majority.
Elsewhere, the Philippines is engaged in phasing out mercury thermometers.
This in spite of the fact that the quantity of mercury, or mercury vapour, which might be ingested or inhaled as a result of a mishap with a mercury thermometer, is so small as to pose a negligible health hazard.
What else can I help you with?
What Type of thermometer uses mercury therefore considered unsafe to use?
The type of thermometer that uses mercury is called a mercury thermometer. These thermometers are considered unsafe because mercury is a toxic substance that can pose health risks if the thermometer breaks and spills. Due to these safety concerns, many countries have phased out or banned the use of mercury thermometers in favor of safer alternatives like digital or alcohol-based thermometers.
What two or three uses of mercury the special liquid?
it is used in thermometers(sorry if i spelled thermometers wrong)
Which instrument is often filled with mercury or colored water or alcohol?
Thermometers are the instrument that is often filled with mercury, colored water, or alcohol. Most early thermometers were made with mercury.
What is liquid metal was used in thermometersr?
Mercury is a liquid metal used in thermometers. However, it becomes a solid at -37.9 F and it can cause mercury poisoning if ingested or inhaled. Therefore, most theremometers use ethyl-alcohol or a plastic strip covered with liquid crystals (called a liquid crystal thermometer).
Who buys mercury chemical?
Person who make thermometers and viewing mirrors.
Is mercury present in all types thermometers?
No, mercury is not present in all types of thermometers. While mercury thermometers are common, other types such as digital thermometers and infrared thermometers do not contain mercury. Mercury thermometers are being phased out due to environmental concerns.
What is the state of mercury in a thermometers?
Mercury in thermometers is in a liquid state, since mercury is liquid at room temperature.
What is common in fishes and thermometers?
Mercury is common in both fish and thermometers. Although nowadays they make thermometers without mercury in them.
Why are digital thermometers used these days?
Digital thermometers have replaced mercury thermometers because mercury is toxic. [Personal commentary: digital thermometers are not accurate and mercury thermometers are so how many people are being harmed by not knowing their temperature versus how many would be harmed by the mercury if accurate thermometers were still used?]
Two kinds of thermometer?
Two common types of thermometers are digital thermometers and mercury thermometers. Digital thermometers use electronic sensors to measure temperature and display it on a screen, while mercury thermometers contain mercury that expands or contracts with temperature changes. Mercury thermometers are being phased out due to environmental concerns over mercury exposure.
Is there mercury in thermometers today?
Most modern thermometers no longer use mercury due to its toxicity. Instead, digital thermometers, infrared thermometers, and other types of thermometer technology that do not contain mercury are widely available and recommended for safer use.
Is Mercury used in thermometers?
In normal and some medical thermometers Mercury is used. That is why you may want to consider using electric thermometers which are more commonly used. They use no mercury.
What is the purpose of mercury thermometers?
Mercury thermometers are used to measure temperature accurately. The expansion of mercury in the glass tube allows for easy visualization of temperature changes. However, due to the toxic nature of mercury, these thermometers are being phased out in favor of digital thermometers.
Why do OSHA and EPA and the AMA all discourage the use of mercury filled clinical thermometers?
When mercury filled thermometers break, the mercury is released. Mercury is toxic to people, pets and the environment. There is a long history of mercury from broken thermometers and other medical devices being improperly dealt with, or even ignored. Since there are adequate replacements for mercury thermometers, OSHA, EPA, AMA and others discourage the use of mercury thermometers and encourage their replacement with thermometers using other technologies.
What liquid mental is used for thermometers?
Mercury is used in thermometers.
What liquid used to be in thermometers?
Most thermometers used to contain Mercury until it was found to be toxic.
How are mercury thermometers used today?
Mercury thermometers are still used in some industrial applications and laboratories due to their accuracy and ability to measure high temperatures. However, their use is declining due to the potential health and environmental risks associated with mercury exposure. In many situations, digital thermometers or other types of non-mercury thermometers are used instead.
