What does “reasonably practicable” mean?
It is balancing the level of risk against the measures needed to control the real risk in terms of money, time or trouble. However, you do not need to take action if it would be grossly disproportionate to the level of risk.

What is the difference between ALARP and SFAIRP?
“ALARP” is short for “as low as reasonably practicable”. “SFAIRP” is short for “so far as is reasonably practicable”. The HSE consider the two terms to mean essentially the same thing with the concept of “reasonably practicable” being at their core. ALARP describes the level to which the HSE expect to see workplace risks controlled.
