From 1st October 2006 The Regulatory Reform (Fire Safety) Order 2005 requires the Responsible Person (RP) of any non-domestic premises to carry out a fire risk assessment, including measures to reduce or eliminate the risk of fire, and identify persons at risk.
As the responsible person you must carry out and regularly review a fire risk assessment of the premises. This will identify what you need to do to prevent fire and keep people safe. You must keep a written record of your fire risk assessment if your business has 5 or more people.
In other words, it is a legal requirement to have competently trained individuals who carry out those activities. In the majority of instances businesses will appoint fire marshals to help maintain compliance. The number you need should be identified through your fire risk assessments.
We have our own Fire Risk Assessor who can carry out a comprehensive Fire Risk Assessment for your premises.
