fire safety and evacuation lift guidance for the London Plan is under consultation. Recognising the situation with the development of EN 81-76, the draft evacuation lift guidance references BS EN 81-76 “if published,” and BS 9991, BS 9999 for evacuation lifts. So, until a BS EN 81-76 is published (2023 at the earliest), the guidance in BS 9991 and BS 9999 should be followed for evacuation lifts. In the meantime, work started at BSI to revise BS 9991:2015; a draft for public comment was published in August 2021. This supported the London Plan policy for all building users to be able to evacuate as independently as possible and included proposals for all developments with passenger lifts to have at least one evacuation lift, and for buildings in excess of 18 metres in height to be provided with more than one.
The proposals contained in the draft version of BS 9991 included significant developments on from the evacuation lift described in BS 9999, Annex G; an evacuation lift would have the ability to be controlled by an evacuation assistant (as we have currently in BS 9999), but crucially the draft introduced the possibility of the evacuation lift to have an automatic
operation to support the self-evacuation of disabled people.
It is not certain whether the final published BS 9991 standard will include these proposals. However, we do expect that forthcoming standards will focus on improving the evacuation lift provision in new buildings. There is currently only one description of an evacuation lift: BS 9999:2017 (Annex G).
While any revised BS 9991 and BS 9999 will set the benchmark for new buildings, in her report Judith Hackitt recognised the need for a continued and determined focus on driving improvements in (fire) safety in the existing housing stock as well as new builds, or the required safety improvements will not occur.
Speaking on behalf of the group Actuate UK at the Construction Leadership Council’s COP26 session, Michelle Agha- Hossein highlighted that 80% of buildings in existence today will still be in use by 2050. While a key issue for sustainability, it also has implications for improving building safety; the improvement of existing lifts will become a major factor.
