This is a question that occurred to me earlier this month when I had occasion to observe an undergraduate laboratory course: If something goes wrong in the lab, do you tell the lab instructor? The “something wrong” could range from breaking a piece of glassware, to getting a stick with a syringe (of non-biohazardous material), to getting a stick with a syringe (of biohazardous or radioactive material), to spilling a nasty reagent. Of course, it could include other mishaps not enumerated here.
I’m not as interested in hearing when students should tell the lab instructor about a mishap, but rather in the conditions in which you would bring the lab instructor into the information loop.
And, I’m interested in hearing the reasons you think some mishaps don’t meet the threshold where you’d want to involve the lab instructor. What’s the main consideration in deciding whether a nick with a scalpel is going to become A Thing, or whether you’ll just hunt down a bandage and a fresh pair of gloves?
