message: I don;t have time to look it up, but the discussion at the bottom about meds can be extended to LSD vs Heroin. With the first it's virtually impossible to overdose, while the margin for heroin is extremely small, and decreases when the body gets used to it, so many addicted persons will keep increasing the dose until lethal overdose in search of the "high".192.88.166.35 (talk) 10:57, 6 May 2008 (UTC)

message: Should probably define and describe the commonly-used term "working load limit", or WLL.  —Preceding unsigned comment added by 72.146.123.231 (talk) 03:03, 25 August 2008 (UTC)

message: The initial description should be broad enough to include other fields of discipline that use Factors of Safety.  The following is a generalized example
Factor of Safety is the ratio of an ultimate limit state over an anticipated condition where:
ultimate limit state - The point after which conditions are unsafe
anticipated condition - a quantified value often dictated by codes, literature and standards of practice
This broader definition can be applied to the engineering fields as well as to the medicinal field per the example at the bottom

replies: text: Yes.  We should also discuss that these are not "points" but distributions with a range of values.  See: Statistical interference.  Rlsheehan (talk) 22:59, 18 February 2009 (UTC)
thread_title:  Initial Description 

message: I believe that the use of the term"reliability" is misleading in this context.  Higher factors of safety do not necessarily improve reliability, which is essentially a measure of how likely something is to fail during a fixed period of operation due to inherent or induced defects.  The FoS must refer to an expected magin of strength above the the expected level.  Reliability is normally associated with randonm processes, thereas here it is addressing the adequacy of a design to meet the conditions in which it is placed.  I suggest that the use of reliability is struck.

replies: text: The wording relating to reliability (and other sections) is certainly awkward and needs improvement.  In many uses, however, reliability is a closely related subject.  Reliability is a probability of performing for a certain time period under specified contitions.  Often a higher design factor of safety will result in higher reliability.  FoS, also can be looked on from a probabilistic standpoint.  Rlsheehan (talk) 16:13, 3 March 2009 (UTC)

message: There should be some examples given for how to calculate FoS based on the literature. It is bizarre that on the page about FoS there is no explanation of how to calculate it! Jackhodari (talk) 00:16, 3 June 2020 (UTC)

message: I put in a request to have the title reverted back to "Factor of safety" because I think the original title is better than "Factor and margin of safety". My understanding is that a margin of safety is a sub-topic of factor of safety, rather than an equivalent term. To better address margin of safety in the article, I would suggest adding some summarized information about the margin of safety to the lead and also changing the Margin of safety link to . However,  and anyone else interested in discussing this, please let me know your thoughts so we can reach consensus about the title. Thanks, Inverted Hourglass (talk) 19:53, 11 September 2021 (UTC)
thread_title:  Title change (Factor and margin of safety) 

message: This issue with the title of this article is that Factor of Safety is rarely used in Structural Analysis. Margin of Safety is the final answer in almost all structural analyses. If it is best to have both the Factor of Safety and Margin of Safety definitions in the same article, either both should be mentioned in the title or the title should be changed to Margin of Safety and the order of the definitions switched. I suggest this for usability and clarity.
