Isn't 'an absolute duty so far as is reasonably practicable' a mixture of terms?
Yes it is Al ...fair point..........................but the responsible person does have an absolute duty to take general fire precautions
"
8.—(1) The responsible person must—
(a) take such general fire precautions as will ensure, so far as is reasonably practicable, the
safety of any of his employees; and
(b) in relation to relevant persons who are not his employees, take such general fire
precautions as may reasonably be required in the circumstances of the case to ensure that
the premises are safe."
So he must, absolute duty, take general fire precautions. Mitigating the effects is included in definition of general fire precautions. The extent to which he takes them is qualified by reasonably practicable or reasonable in the circumstances of the case...depending on whetehr employees are involved.
