They could fix that with closer monitoring by staff, but that would add to the cost. Still, pay someone $10 - $15/hour to keep an eye on things and make sure folks clean up, shouldn't be a big expense compared to the cost of the equipment.
Don't forget that you have to have such an individual who truly knows
how to use the stuff. If someone uses a bandsaw to cut some 25mm steel that is 150mm wide, that's one thing. Knowing that you shouldn't cut more than 50mm at a time (or about 24 teeth) unless you want to cook a $80 blade is another. (Solution: Prop it up slightly at an angle. Pro tip: Make sure the prop material can't catch the teeth as it comes down, otherwise it will get grabbed and slammed against the backstop, taking out the blade with it.)
As with these sort of tools, having them is one thing, knowing how to use them and all their dirty little secrets and perks is quite another. Another instance, press brakes. Any fool can put some sheet metal in and press the down button -- but making a right
bend at the exact
location is quite something else. Another example: torque wrenches (both the beam style and the clicker style) are not
breaker bars. Standard 12-point sockets are not
meant to be used with impact wrenches (either the kind used in tire shops or the kind that is meant to be struck with a hammer to free stubborn bolts). Screwdrivers are not
prying tools, just because they happen to be close in design to one doesn't make them one (although light prying is okay), neither are they chisels, because they lack the proper (non-Harbor Freight inventory is a plus) hardened tool steel with a properly tempered edge. A manual tap wrench + tap is not to be just threaded all the way down like a screw, unless an endless supply of taps is on hand.
Stuff like that. Policing and keeping track of everything without people doing stuff like spraying the visual window on the door of the sand/media blaster, turning it all opaque is a full time job. You want to see bad, try a high school shop.
