Regulation 5 of the Confined Spaces Regulations 1997 requires ‘suitable and sufficient’ emergency arrangements to be in place for the rescue of any person entering or working within a confined space. This regulation is clear that arrangements need to be prepared before people enter confined spaces.
Furthermore, they should also be suitable for rescuing people in an emergency, even if the emergency was not caused by a specific risk - i.e., electric shock, contact with moving vehicles, fall from height. Paragraph 3 of Regulation 5 stipulates that the emergency arrangements should immediately be put into operation should an emergency occur.
