Answer:
SAFETY: Whether it be a commercial site like shown here or a residential site, a vertical penetration is nothing short of a trip hazard!!!
Most morning toolbox meetings start off discussing the usual trips, slips and falls as hazards but a site with multiple penetrations as shown in these photos cannot realistically set up physical barriers. So the BRIGHT SAFETY ORANGE OF THE APACHE goes a long way toward identifying a floor level hazard for contractors working in these zones!
Just another benefit along with the vapour barrier and free control slip joint that Apache also offers.
