Why unlabelled bottles are more than a paperwork issue
An unlabelled bottle creates three separate problems. Nobody can tell whether it is safe for the surface in front of them, which produces damage. Nobody can tell whether it is safe to mix with anything else, which produces the classic and genuinely dangerous combination of two products that should never meet. And if someone is affected by it, nobody can tell a medical service what they were exposed to.
Small premises accumulate these bottles because a concentrate is decanted for convenience and the label is added later, meaning never. Staff turnover then removes the only person who knew. In a cafe, salon or consulting suite the cupboard is often shared between the cleaner and the venue's own staff, which compounds the problem by giving each party a reason to assume the other knows what is in there.
