Warning Will Robinson! In the end, it's not our stuff in jeopardy. So why so much concern? I had to replace a fire rated door in my house because the previous owner had punched a pet door in it completely negating its purpose. Important to me, not to them.
The guy at Window World where I ordered a new one shared that his dog and a pet door were far more important than a fire rated door.
An insurance investigator finding such a thing would reject any claim for fire loss. We all make choices. And really, who are we to police everyone and their actions with no direct involvement?
I worked Level l trauma for years. How many stupid things came through the doors in just one shift? Not my place to judge.
