Unattended experiments

Some experiments take time: hours, days, even weeks. This means that the experiment will be set up and running in the lab while you are not there. You have an ethical obligation to prevent harm to others in the lab by ensuring that they are aware of your experiment and its hazards. Make sure they know:

  • What the purpose of the experiment is;
  • To whom it belongs;
  • What behavior indicates that something has gone wrong; and
  • What to do if something does go wrong.

You could tell the members of the lab all that information, but some lab members might not be present and others will promptly forget. Depending on the lab’s occupants to “know what’s going on” is foolish—your colleagues may know the general type of research you do but they are not familiar with the details of all your experiments. Far better is to post the information so that anyone in the lab can easily see what your experiment is, how to identify abnormal situations, and what to do in that event.

A sample form is available for you to use directly or adapt to your lab’s needs. (The file is in Word format for easy modification.) The form is written to allow use in teaching as well as research labs. You should prepare two copies of the form: one to post near the experimental apparatus and one to post in a safe place (like on the door). In an emergency, no one may be willing to approach the apparatus to read the information sheet!
