This reminds me to the following help desk statement: "The cup holder on my computer stopped working."

I'm not sure that I agree that foreseeable misuse is an oxymoron, although I prefer the term "reasonably foreseeable misuse". We know that certain types of products will either be used for something that is not the original intended purpose or they will be used for their intended purpose in an inappropriate fashion. For the first example, I can state that a wooden pencil is intended to be used for writing. However, I can foresee that some users will chew on their pencils. The pencil is not designed, intended or marketed to be used for stress relief, but we know that people will chew on them. One design safeguard would be to make sure none of the materials used are toxic if ingested. For the second example, I will cite people standing on the top level of a ladder. The user places themselves in an unstable position if they stand too high on the ladder. The ladder is still being used for its intended purpose, but it is being used in a way that that significantly increases the risk to the user. In this case, a design safeguard becomes much more difficult to implement. Most ladder manufacturers implement instructional safeguards. Modern ladders are now plastered with caution and warning statements. Mr. Nute asks what foreseeable misuse of a computer would be. I would propose that using a computer outside of the published environmental conditions is foreseeable. I can foresee somebody cleaning the keyboard on their laptop with a wet rag. I can foresee leaving a laptop in a car on a hot day. Either case may create a potential hazard for lithium-ion batteries. Many computer manufacturers implement both design and instructional safeguards for both of these conditions. Neither is the intended use of a computer, but might they be considered foreseeable? The problem comes with determining what "reasonably" means. Many courts will interpret this to be what a "reasonable person" would do. This only shifts our problem to defining what a reasonable person is. I will offer a slightly more humorous view of misuse in the following video. Is this a reasonable person or reasonably foreseeable? https://www.youtube.com/watch?v=SarpypNskcc Ted Eckert Compliance Engineer Microsoft Corporation [email protected] The opinions expressed are my own and do not necessarily reflect those of my employer. -----Original Message----- From: Richard Nute [mailto:[email protected]] Sent: Friday, October 17, 2014 11:33 AM To: [email protected] Subject: Re: [PSES] Misuse mains cordset Misuse is unique to what you want to do. You use (misuse) the product to accomplish your particular objective which differs from the intended use of the product. You stand on a chair (intended for sitting) to reach something that would otherwise be out of reach. The US TV program MacGyver (~1985-1991) was based on misuse of common things to solve a problem. "Foreseeable" misuse is an oxymoron. You can't foresee misuse of a product unless you know what the user wants to do (his objective). The product and its misuse was the fun of the MacGyver TV program. More seriously, what is a "foreseeable misuse" of a computer? The term "foreseeable misuse" has been foisted upon us for years, but we don't know what it means or how to protect against it (even though we are required by some safety standards to provide safeguards against "foreseeable misuse"). How do you protect someone who stands on a chair? How do you protect someone who misuses a computer? My neighbor took the guard off his portable saw and was injured. This was clearly misuse. How do you provide protection when the user removes the safeguard? For an eye-opening treatise on misuse, see Don Norman's "Psychology of everyday things" and his other books.

A part of this is all about foreseeable misuse. That said I do not feel it is appropriate for a manufacturer to "police" every action if the end user. You best bet may be to mitigate by saying something along the lines of "not for use for any other purpose..."
