Yeah, considering I’ve seen several examples of fire alarm devices being blocked by various things.
Not majorly blocked. still seems accessible to me
Yeah, but that’s likely why that sign is there: to make sure that anybody who comes near that area knows not to block the manual station (even if it’s not blocked at present).
I’ve seen some crazy stuff. Like, some people aren’t going to let a pesky strobe or pull station get in the way of where they want to put their shelving…
That is hilarious!! The audacity to proceed to block the alarm with a cart is funny! @HenBasket that was what I was thinking!

In a similar fashion I once found a fire extinguisher cabinet who’s door was not only blocked by a shelf from the way both were mounted, but it didn’t even have an extinguisher in it!
