Principles of fire risk assessment:

The following principles of FRAs apply in the UK as they do in the USA:

• justifying assumptions,

• stating data sources,

• giving the qualifications of the person conducting the FRA,

• a hazard is the potential for harm to occur,

• risk is likelihood of that hazard being realised and can be combined with the severity of the consequences,

• they can be conducted quantitatively (numbers) or qualitatively (ideas),

• they can be comparative or absolute,

• uncertainties should be accounted for

• 'what if' situations should be considered,

• matrices are sometimes used.
