An employer conducts the undertaking so that, so far as reasonably practicable, anyone not in the employer's employment who may be affected by it is not exposed to risks to their health and safety.

A self-employed person conducts the undertaking so that neither they nor anyone else who may be affected is exposed to such risks.
