We have to assume the guy standing there with his foot casually propped up on this semi tire as it’s being filled had no idea he was about to be thrown for a flip when the tire violently exploded, but in all reality, he should have never been in that situation to start with. They make tire cages for a reason, and it’s to prevent injuries and fatalities caused by big rig tires failing in such a manner.
Safety should be priority number one in any shop, but one that deals with semi tires should especially focus on handling them safely. Using a tire cage is a simple step to take when inflating any tire that can prevent injuries and further damage to the shop and its contents. Many cages come with built-in inflators to properly inflate the tire so you can move on to the next task while the inflator finishes one job for you, saving time as well.
If you don’t have a cage, place the tire in the open, attach the filler, then back away! At least that way you’re clear of the tire if it fails. The last thing you want to do is stand right beside a tire as it’s being inflated, and you certainly don’t want to prop up on it, as you can see in this clip.
