Description of the Project
Advice or Ruling
A pressure vessel must have a safety valve, rupture disc or similar device to limit internal pressure below the burst pressure of the vessel. The safety valve shall relieve to a safe or remote area.
We had a previous incident in which a student built his own pressure vessel in his basement and raised the internal pressure by several atmospheres - (it may have been tens of atmospheres). An engineer on the judging team explained that he was legally obliged to report this breach of Provincial Laws relating to pressure vessels. He wanted to disqualify the student.
In this project, the student is not pressurizing the drum by pumping air in it. He does have a tube inserted that will prevent a large pressure increase.
The Ethics Committee believes that this project is acceptable for the CWSF.

These case studies summarize interesting examples of science fair projects involving humans or animals submitted to the Youth Science Canada National Ethics Committee for review. A brief description of the proposed project is given, along with the ruling given by the Ethics Committee. Some details may have been changed in the descriptions so that the original source cannot be identified. The ethical challenges described have not been changed.
