I would say a overall RA of how you employees works, each year we do generic RA and document this and go thought it with the employees (like mobile phones where driving), a RA to a customer is for them to know how safe you work, most commercial sites wont those under the management of work regulations, as for house holders it’s a different matter and insurance companies will dictate to a point, because if you trip over something when on there property which was unsafe and you not able to ever work again for what ever reason then you are initialed to compensation – as they permitted you to work there
