After realizing that the water bath was not at the correct temperature, what should the technician do?

Reporting the problem to quality assurance is essential because it ensures that any issues with equipment or experiment conditions are formally documented and addressed. Quality assurance protocols are in place to maintain the integrity and reliability of experimental results. When the water bath is not at the correct temperature, it can significantly impact the outcome of an experiment, potentially leading to inaccurate or invalid results.

By reporting the issue, the technician can help to rectify the situation, ensure that the equipment is properly maintained, and prevent future errors. This action also provides a record for quality auditing and helps maintain compliance with established laboratory standards and protocols. Meanwhile, other actions like continuing the experiment or simply adjusting the temperature without documentation or reporting could compromise the integrity of the study and violate laboratory practices.

Recording the temperature in the logbook is important, but it does not address the immediate need to communicate the potential impact of the observed problem on the experiment's validity to the appropriate quality assurance personnel.
