How far can we fill the Sharpssmart sharps container?

Only fill the container to the marked fill line. If utilising a regular version Sharpsmart with an inbuilt safety tray, the tray will retract to a 'full' position once sharps volume reaches the fill line. Once the Sharpsmart container is full, ensure the front lock is secured, and both side locks are secured by depressing the red tabs and sliding the side locks forward to permanently lock.
