Does anyone have any information on suspension trauma and first aid requirements? On speaking with a fire fighter it would appear that they need to review their emergency rescue proceedure training as the present ones could induce post suspension trauma. I am advising sectors of the construction industry regarding, rescue of injured persons working at height. In the event of a fall arrest victime being unconcious, it is critical that the right first aid be administered, this is not covered under the present four day first aid courses.
Any pointers on this would be appreciated.

A word with one of the Harness suppliers who offer training would be of particular interest with regards to "Suspension Trauma".
On a course i took with SALA [no not advertising for them] and on training courses i had to give in the past,great detail was paId into NOT releasing a person from a harness too quickly, if they had been suspended for any length of time.
The harness had to be released in a systematic way with the person in an upright position so as to avoid a great surge of blood to areas that had been starved, and in so reducing the chance of serious harm.

Look at NASC SG4.05
Section on trauma whilst suspended in safety harness.
As rule only trained persons will be able to deal with person suffering from suspension trauma, as blood restiction will be critical to injuries.
Limiting the time of suspension is the critical point, and is part of training for persons working with others using safety harnesses.

Thank you for that Glen, looks like I will have to purchase a copy unless I can borrow one from a scaffolding company.

Posted By Peter R Peacock Try www.hse.gov.uk/falls/research. The document is called CRR451/2002 Harness Suspension. It is quite a detailed document but has all the information you will need in it.

Sala, the harness manufactures have an attatchment that can be fitted to the harness to be used in the event of a fall to prevent the effects of suspension trauma.
It is basically a two part strap which hooks together and the person stands in it or on it and this takes the tension off the harness.
take a look at the website they are cheap items but may be of use to you?

Posted By Richard Hinckley As a leading provider of Height Safety Training this is a subject that has featured within our training courses now for a number of years now and there are a wide range of safety products available that extend a persons ability to be in suspension for extended periods. For those interested in the subject you wish but you may wish to take a look at the following web site, I think that you will find it answers most questions on the subject. www.suspensiontrauma.info

Having recently taken a Retrieval training instructors course I took Phils advice and downloaded the pdf report 451, it is a fascinating read (only half way through so far), I am amazed and dissapointed that the only mention of any of this in my training was that "you probably need to be looking at getting them down within 20 minutes or so". More emphasis on the requirements after and during rescue is something I will be adding to my lessons.
Thanks for the tip Phil.

While reading the report I noticed that on pg 26 Dr Amphoux states that a worse case scenario fall would result in a drop of 4 metres with a 2 metre lanyard and clipping on at foot level, this presumably accounts for the lanyard and height of the wearer plus displacement of harness. (no accounting for shock absorber)
I am also aware that the NASC and HSE recomend a 4m clip on point for scaffolders under SG4, I am puzzled as to why this is so?
Recomended lanyard length for scaffolders is 1.75m, the shock absorber is a possible 1.75m and then 2m alowance for height of scaffolder + displacement of the harness, surely a clip on point of 5.5m would be more suitable.
It has been suggested to me that information supplied in the sala handbook that shock absorbers are 1m in length was a misprint and they are actualy 1.75m,
Another worrying thing for me on this issue is that since the introduction of the new WAH regs, I have seen on many sites (chemical plants, power stations etc) an insistance that scaffolders are clipped on as soon as they leave the ground.
This may be due to a misinterpretation of the regs, but can quite obviously serve no purpose yet is not questioned??
Any advice,corrections or comments gladly appreciated.

1.75m is the maximum permissable extension of the energy absorber and hence this figure is often quoted in fall distance calculations.
There are various theories for what has commonly been called 'suspension trauma'. Although most of the theories and research into such have merit a complete understanding has not been established. For each theory an opposing one can be found. For each theory there is also one or more myths as to cause, effect and prevention. This is why on some training courses the advice only revolves around time limits.
The reference to releasing a harness slowly after suspension is a little misconstrued. This is based upon the theory that the cause and effect is similar to that experienced with crush victims were the supply of blood to the lower body is restricted. In a rescue of a suspended person you have to recover them by lowering direct or onto stretcher etc or lift them. Either way they are ultimately released from the pressures exerted by their harness as soon as they are lowered/lifted onto a stable base (ground/platform). Therefore the slow release of the harness is immaterial.
If in a fall situation and conscious then movement of the legs, lifting of the legs [believed to help]or standing in a loop connected to the end of your lanyard helps to relieve the pressure and keep the circulation going. TIP: Don't waste your money on some of the manufacturers 'special' devices for this. A simple round sling or piece or rope carried in a harness pouch will suffice. Connect end to lanyard/thing your hanging on [don't open lanyard connector]by looping through itself or use seperate connector. Having done this then stand up in it periodically.
If anyone needs specific info/advice reference 'suspension trauma' email.

Posted By Phil you are quite right in the fact that a good samaritain 4 day first aid at work responder could in fact induce a cardiac arrest with improper treatment. A control measure of dial 999 is not enough either, i am training Firefighters in suspension trauma treatment at the moment. Before our course, they had no appreciation of the consequences of lying a suspension trauma victim down flat. if you require further info, let me know Phil www.trauma-resus.com

be careful as the normal 'recovery position' can be very dangerous and even bring on death re 'suspension trauma'
This is specialist stuff. The average F-Aid at work course offers only basic info for low risk areas

I have had stand up rows with auditors in the past about workers not using fall arrest equipment when working at 3metre ceiling height. A bit of quick reading shows how FAE are of limited use under 4 metres. I think the HSE and other authorities on the subject sound as though they hedge their bets by saying between 4-6 metres is an acceptable height for clip on(apologies folks do not have a source to cite, read a HSE CRR about 2 years ago) but are right to because 4 metres might save a life by changing a head injury into a leg injury when a harness rights a faller.
I still see guys choke their karabiner with their lanyard all the time because the krab won't fit around the pole/beam/joist etc which usually means the krab will fail at about a third of it's rated value along it's length. (Safety nerdism has a price and that's 20p more an hour than the other bloke, quite reasonable really)
