This article doesn't actually say why it's a problem that they were using dish soap as a lubricant.
Yeah if it's what I'm thinking it is, the seal sounds like a rubber bit that goes around the door. Using soap to get it in place is probably fine unless there's some exotic chemical interaction I'm not aware of - you do the same thing when building a tire to get the rubber around the rim.
When you're pulling cable through conduit it's common to use dish soap. Boeing definitely has issues, them using dish soap isn't one of them.
probably an EHS thing. chemicals need to come from a single source, in containers with a standard warning label.
I assumed its a process thing. As in, every step should be properly documented so audits can be effectively performed. It's just annoying that all of these articles make it seem like using dish soap as a lubricant during the install process is inherently bad.
