Emergency evacuation from high rise buildings
Rank: Guest

Posted By Jan Pawlicka
As the lifts in a building are not available for use during emergency evacuations this provides a challenge to the disabled and less able occupants therein, particularly for those on the 13th floor.
What provisions are typically in place to deal with this - evacuation chairs are a possibility but may not be suitable for a heavier person weighing in excess of 20 stone? Are there any other options available, information on type of kit that works particularly well, options to avoid.
Thanks

Firstly, do said persons need to be located on the 13th Floor?

If it is a high rise building why aren't the lifts available? You are required to have firefighting lifts for high rise buildings and it is permitted to use these for your MIP evacuation strategy.

Hi,
The stairmate can be a good option, approx £3000 about 3 years ago if memory serves. I've had wheelchair users that have refused to use evac chairs as too dangerous but are happy with the stairmate. It is a sort of caterpillar type trolley that I believe can be used with any wheelchair. So the wheelchair user stays in their own wheelchair and one person can then help them to evacuate down the stairs. Find it at:

As Stephen says there are products available to get a wheelchair down stairs, but it's a much bigger issue than that. Will there be enough people and devices available for all the residents, on each floor, who need them? Where can they be stored securely? Will using chair systems cause problems? (they work, but they move very slowly compared to a stampeding crowd on the same staircase, so if it's busy they can cause no end of problems). High-rise evacuation modeling is a complicated science (more so since 9/11) and every case is different.
Depending on the nature of your building and its occupancy, refuges may offer a better solution, despite seeming counter-intuitive.

Like Simon asked - do they need to go the top floor? Risk assessment??

I agree with Shaun Mckeever's post about using the firefighting lift. Such provision is already in place, requires little training and may be safer/faster than 'wheelbarrowing' someone down 13 floors!! - especially a heavier than usual person.
However, Some questions:
Firefighting lifts are usually operated/switched from the ground or access floor. When switched, the lift car proceeds to the access floor and all other controls are isolated.
So when utilising FF lifts, how does a disabled person call the lift (if on the 13th floor as this person is) as their control will be non operational?
If the procedure involves somebody operating the lift at the ground floor and then taking the car up to the 13th floor (perhaps through the fire floor), how is that risk assessed & addressed?
Alternatively, does this procedure rely on the lift not being switched to firefighting mode. In which case, how can you ensure that the lift will arrive on the 13th floor as soon as possible? (I expect we have all experienced long waits for lifts. It must seem like an eternity when alarms are sounding and your colleagues are leaving via the stairs!!)

Hi,
A previous employer had a fire evacuation lift installed at very great expense. The plan was to have another one installed at the other side of the building, wheelchair users being located between the two lifts, so in the event of a fire at one side they would go to the other to an evacuation lift. For the evacuation procedure to operate effectively it required an evacuation controller, lift car attendant and ground floor attendant always on site with back-up for each person to cover sickness/holidays and who wants to get in a lift even an evacuation lift during a fire. We never had to use it in anger but it was an expensive and cumbersome procedure and the 2nd lift was never installed. I think the simplest and best solution for all must be wheelchair users located on ground floor or lower floors where they can be evacuated without too much trouble down one or two flights of stairs but always ensure the individual needs of each are accommodated through PEEPs.

Hi, sorry guys check the regs there is no requirement to provide a "fire fighters lift". Assuming it is a tenanted housing property.. problem with evac chairs etc. is who will use them to get people out? also what about non emergency issue..people wish to go shopping..have a doc, dentist appointment etc. etc.
Relocation is the best, most effective and efficient method.
Cheers

I am intrigued about your comments about this 13+(?) storey building not requiring a firefighting lift.
Have a look at Building Regulations Approved Document B (B5, diagram 51 on page 113). It shows clearly that buildings in excess of 18m above fire service access level must have a FF shaft and lift.
Have I missed something?

Have a look at the copy of the above firstly.
A lot of issues need to be assessed first.
As mentioned try and reduce risk in first place by removing such persons from 13th floor. If not possible then create PEEPS for each individual. Get these people involved, assess what they prefer and assess their preferred options for escape.
Assumptions should not be made about the abilities of wheelchair users (if that is their disability?) and they should not be excluded from a building because of false assumptions about their ability to leave the building safely. The preferred method of escape by most wheelchair users is horizontally to another fire compartment, or to outside the building, or vertically by the use of an evacuation or fire-fighting lift. If these options are not available, or not
in operation, it may be necessary to carry a person up or down an escape
stair.
Some people have mentioned the weight of the person, but these Evac Chairs are great to use even with the most heaviest of people, if training is in place.
What is also required is co-ordination and co-operation in that all responsible persons communicate their PEEPS/emergency plans with each other.
Another factor is the fire/evacuation strategy in place. 2 stage phased evacuation will alert all disable persons in building when other areas are on standby to start egress with their buddies or however their PEEPS works. Compartmentation is a factor to and also informing the local F&RS if a fire fighting lift is to be used as they will turn up wanting to take control of lift to get to 13th floor and below ASAP. As mentioned if you want to use fire fighting lift you need someone (security)to ensure control of lift. Do lifts ground on full alarm or at the first stage.
Plenty to think about, but should be straight forward enough once other info is taken into account...........unless you have x 10 wheelchair users on 13th floor, in which they should not be there in first place lol.
