A “responsible person “ is defined in the Regulatory Reform (Fire Safety) Order 2005 (England and Wales). The Fire (Scotland) Act 2005 (Scotland) refers to a “dutyholder”.
A responsible person/dutyholder is usually the employer, owner or occupier. They have a duty to assess the risk from fire and put measures in place that provide adequate protection against the risk of fire. (e.g. escape routes, warning systems). More information and guidance on how to comply with the law can be found at the Firesafety community.
