You wouldn’t let just anyone roam freely within your factory, warehouse, or other industrial space. Not only are there the safety risks I outlined above, but you also may have products you want to protect and/or processes that constitute intellectual property that can’t be shared.
Sure, this can be a concern in commercial offices as well, and obviously you’d want to trust the individuals cleaning your home, but in an industrial space these concerns are heightened. Outside of just intellectual property, the products you may store in your warehouse could also be at risk. Check with your provider, and with reviews online or from others in the industry, about problems they have had with theft or damage to products or property.
