Work Rescue

The need for a rescue plan
YOU are standing outside the doorway of an employee’s home, hands clammy, and also a cold sweat on your brow, a metallic taste inside your mouth. You’re feeling so nervous that you might throw up or even faint.
Precisely why do you feel this way?
Picture as an employer the way you would feel if you were about to explain to a family exactly why their loved one, a member of your workforce has died after falling from height.
Precisely why did this have to happen?
You understand that you simply overlooked, or just did not get around to the job of planning for rescue and emergencies, which would have saved that employees life.
Planning for rescue and emergencies in regards to work at height is actually more than a monetary concern; now it is a legal and ethical responsibility for all employers. The Working at Height Regulations 2005 and BS8437:2005. 4 (1) & (2) says:
“Every employer shall ensure that all work at height includes planning for emergences and rescue.”
My intention is to provide food for thought, ideas for the future and maybe some solutions to your immediate problems.
The advantages of a rescue plan
Even in work places of the very safety conscious employer’s accidents occur, consequently a rescue plan is an essential component of working at height and really should be managed by way of a working at height method statement and risk assessment, and should include training and practice. The lack of any form of post-fall rescue plan not merely puts the victim at risk, but also puts rescuers in harms way. Unplanned attempts at rescue frequently bring about secondary and tertiary injuries or deaths.
CRITICAL PHASES OF A RESCUE.
There are 4-phases of a rescue, each phase presents unique safety challenges and has to be considered individually. As with all safety issues, increasing safety in one area can compromise safety in others. Rescue operations are carried out under extreme pressure, whatever training your employees have had or are yet to have, will determine how they react as each phase develops.
PHASE 1- Before the fall
The key issue of fall protection prior to a fall is compliance. If a harness is too uncomfortable, or interferes too much with carrying out the work being done, operatives may not use the equipment or may modify it (illegally) to make it more tolerable. A poorly fitted harness can result in severe injuries following a fall making rescue more difficult.
PHASE 2- Fall Arrest
The whole concept of fall protection is that operatives who fall will be stopped by a shock absorbing tethering system. Unfortunately, the posture of the falling operative is unpredictable.
Depending on the harness attachment point and the position of the operative’s body at fall arrest, different harness attachments offer different advantages. An attachment near the shoulders means that any drag from the lanyard will serve to position the operative’s body in an upright position so the forces are distributed from head to foot. The head is somewhat protected if the legs and body precede it in the fall, but this offers some disadvantages after the fall arrest is completed.
PHASE 3 – Suspension
Many safety professionals naturally assume that once a fall has been arrested then the fall protection system has successfully completed its job. Unfortunately, this is not the case. An operative suspended in an upright position with the legs dangling in a harness of any type is subject to suspension trauma and orthostatic intolerance.
Fall victims can slow the onset of suspension trauma by pushing down vigorously with the legs, by positioning their body in a slight leg-high position or, by standing up. Harness design and fall injuries may prevent these actions.
PHASE 4 – Post-fall rescue
Rescue must come rapidly to minimise the dangers of suspension trauma. The circumstances together with the lanyard attachment point will determine the possibility of self-rescue.
In situations where self-rescue is not possible, operatives must be supervised at all times. Regardless of whether an operative can self-rescue or must rely on others, time is of the essence because an operative may lose consciousness in only a few minutes.
For conscious casualties we recommend (where possible) that those suspended keep their legs moving to keep the blood pumping and reduce the risk of venous pooling, whilst deploying a self recovery rescue system.
For unconscious casualties we recommend using a raising or lowering system to facilitate the rescue of an unconscious casualty, ideally the equipment chosen will allow the rescue to be carried out in less than five minutes.
Toxic Shock – Suspension Trauma – Orthostatic Intolerance
Unless the operative is rescued promptly using established safe procedures, suspension trauma caused by orthostatic intolerance could occur and result in serious or fatal injury as the brain, kidneys and other organs are deprived of oxygen. Most users of fall protection equipment are unaware of the hazard of suspension trauma.
Venous pooling – The need to faint and fall over
Death from suspension trauma is caused by orthostatic intolerance and is the result of venous pooling. This can occur any time a person is required to stand still for prolonged periods and may be worsened by heat and dehydration. Major blood vessels pass through the muscles in the legs. The movement of these muscles assists circulation by squeezing the blood back up towards the heart. If the muscles stop moving, gravity pulls the blood
down into the legs and reduces blood flow to vital organs
First Aid Procedures
Following completion of evidence based review of published medical literature: HSE has clarified guidance on the first aid management of a person falling into suspension in a harness who may develop ‘suspension trauma’.
The key recommendations are:
a) No change should be made to the standard first aid guidance for the post recovery of a semi-conscious or unconscious person in a horizontal position, even if the subject of prior harness suspension.
b) No change should be made to the standard first aid guidance of ABC management, even if the subject of prior harness suspension.
c) A casualty who is experiencing pre-syncopal symptoms or who is unconscious whilst suspended in a harness should be rescued as soon as is safely possible.
d) If the rescuer is unable to immediately release a conscious casualty from a suspended position, elevation of
the legs by the casualty or rescuer where safely possible may prolong tolerance of suspension.
e) First responders to persons in harness suspension should be able to recognise the symptoms of pre-synsope.

There are many other things to consider when planning for rescue, these include:
• How will you know someone has fallen?
• What communication systems are in place, how will your employee call for help?
• Who do your other employees call when an incident occurs?
• Incident Information, what information does the emergency services require?
• How safe will the rescuers be, before, during and post incident?
• How will the rescuers get to the casualty?
• Can you rescue in under 5 minutes, is there adequate equipment available?
• What if the casualty has additional injuries?
• Other considerations such as:
Ø Language barriers
Ø Adverse weather
Ø Working alone
If you produce a rescue plan which is well thought out and sufficiently detailed to deal with the majority of, if not all situations, receive appropriate training, and practice this regularly. It is extremely improbable that you’ll ever need to explain to an employee’s family of the death of a loved one, or give an account to the HSE as to the reasons you didn’t have a plan in place, when it’s today a legal requirement to do so.
