Question

multiple - choice question
thermometer safety includes all of the following except:
place them away from the edge of the lab table
disposal of thermometer depends on the type of liquid inside
a teacher should clean up a broken thermometer
shake the thermometers to push the liquid inside down

Explanation:

Placing thermometers away from the edge of a lab - table prevents them from being knocked off and broken. Disposal of thermometers depends on the liquid inside (e.g., mercury - containing thermometers require special disposal). A teacher should clean up a broken thermometer due to potential hazards. Shaking thermometers to push the liquid down is a normal and safe operation for certain types of thermometers (like clinical thermometers). Since all the other options are related to thermometer safety, and this is an "except" question, we need to find an option that is not a safety - related aspect.

Answer:

There are no options labeled, but assuming the options are in order: None of these are incorrect in terms of thermometer safety as described. If we had to pick one that might be misconstrued in a non - safety context, it could be argued that "shake the thermometers to push the liquid inside down" might be seen as a non - safety item if one misinterprets it as being about the general handling rather than a proper use step. But in reality, all are valid safety or proper handling aspects. If we assume there is a misprint or oversight in the question setup and we consider the most common sense, none of these are exceptions to thermometer safety. If we force an answer based on the format of the question asking for an "except", more context or correct options would be needed.
