Provision of information to employers and the self-employed from outside undertakings

20.—(1) The responsible person must ensure that the employer of any employees from an outside undertaking who are working in or on the premises is provided with comprehensible and relevant information on—

(a)the risks to those employees; and

(b)the preventive and protective measures taken by the responsible person.

(2) The responsible person must ensure that any person working in his undertaking who is not his employee is provided with appropriate instructions and comprehensible and relevant information regarding any risks to that person.

(3) The responsible person must—

(a)ensure that the employer of any employees from an outside undertaking who are working in or on the premises is provided with sufficient information to enable that employer to identify any person nominated by the responsible person in accordance with article 15 (1)(b) to implement evacuation procedures as far as those employees are concerned; and

(b)take all reasonable steps to ensure that any person from an outside undertaking who is working in or on the premises receives sufficient information to enable that person to identify any person nominated by the responsible person in accordance with article 15 (1)(b) to implement evacuation procedures as far as they are concerned.

What the Enforcement Guidance says:

 

The responsible person must notify other employers whose employees work in or
around his premises of any risks, and of preventive and protective measures. They must
give any other non-employees or self-employed persons appropriate instructions and
information on risks. The responsible person must also ensure that the employer of
other employees working on the premises, and any person from an outside undertaking
working on the premises, is notified so as to be able to identify the persons nominated
to implement evacuation procedures.
 
However, in enforcing this article, enforcing authorities will wish to have regard to
practicality. For example it is not reasonably expected (and not desired) that each
responsible person will notify the Postmaster General of the findings of their risk
assessment simply because a postman or postwoman visits their premises daily.
Notification of significant findings that may affect the employee would be a reasonable
expectation.
