Midders how is the landlord an RP all the premises and common areas are workplaces under the responsibility of the tenants(RP's)
Look at the definition of Responsible Person.
I think I have caused confusion with what I call the "person having control" because Article 3 defines a Responsible person using this term.
In this Order “responsible person” means—
(a)in relation to a workplace, the employer, if the workplace is to any extent under his control; .
(b)in relation to any premises not falling within paragraph (a)— .
(i)the person who has control of the premises (as occupier or otherwise) in connection with the carrying on by him of a trade, business or other undertaking (for profit or not); or .
(ii)the owner, where the person in control of the premises does not have control in connection with the carrying on by that person of a trade, business or other undertaking. .
The terms above shouldn't be confused with those used in Article 5(3) which talks about any person who has to any extent control of the premises.
See my posts above about sole traders, and local branch manager of Woolworths and it should hopefully make sense as these are Article 5 Persons whom have to any extent control, whereas the landlord and any tenants who employ people of course do have control over the premises but are de jure Responsible Persons and there are differences between the persons described in Art 3 to those in Art 5
... if the landlord is failing miserably and creating a dangerous situation then the RP might have no choice but to cease using the premises until things are sorted.
Why do you say that the LL is not a person having control if there are common escape routes and a FA system?
Yep spot on - if the landlord is a numpty of course!
