Which will ensure laboratory safety during the experiment? Check all that apply.

1. Using beaker tongs to handle the hot beaker
2. Reading the thermometer accurately
3. Checking the beaker for chips prior to heating on the hot plate
4. Using a beaker instead of an Erlenmeyer flask
5. Turning off the hot plate after use

Answer :

Final answer:

To ensure laboratory safety, use beaker tongs to handle hot beakers, check for chips in glassware before heating, accurately read thermometers, and turn off the hot plate after use. The correct choice of glassware also plays a role in conducting safe experiments.

Explanation:

Ensuring laboratory safety during experiments is crucial to prevent accidents and injuries. Here are actions that would ensure safety:

  1. Using beaker tongs to handle the hot beaker prevents burns and allows for the safe transfer of heated glassware.
  2. Reading the thermometer accurately ensures that you are aware of the temperature and can prevent overheating or reactions occurring at unintended temperatures.
  3. Checking the beaker for chips before heating on the hot plate is important as damaged glassware can break under heat and cause injury.
  4. Turning off the hot plate after use prevents unintended heat exposure and potential fire hazards.

Although using a beaker instead of an Erlenmeyer flask might not directly impact safety, the correct choice of glassware is important for the specific requirements of an experiment. It is essential to follow all safety guidelines given by the instructor and to be alert while performing experiments in the laboratory.
