Dear Reader - As we enter 2009 we continue with our serialisation of extrication evolutions 'MPV - Roof fold Down', 'Firefighter Protocols for Life Threatening Situations' and Fatal Crashes - Truck V's Car'. As we leave 2008 it is with deep concern that in this issue we highlight firefighter fatalities and the increase in firefighter mortality and injury here at home in the UK. The lack of recognition for death due to Firefighter instruction based on age old practice and inadequate information gathering, poor training facilities and on-duty health related issues, must now be addressed. Over the last 40 years I have never known it any different and it continues to be a scar on the face of the British fire service and an indictment of scurrilous management flaunting in the face of health and safety legislation. However, to be fair, the UK fire service is well ahead of their American counterparts as Distress Signaling Units and SCBA entry boards {Passport System), guidelines (search and tag lines) and emergency teams (Rapid Intervention Teams) have been in place for literally half a century - Stay Safe out there! I, Len Watson editor - [ FEEDBACK ] - |

Extrication Evolution for Dual IC and SIPS In the previous installment I asked readers to familiarise themselves with our Document for discussion - 'SRS smart systems Logic' - [CLICK]. This study document will enable the reader to fully recognise the risks involved and equate the SIPS configuration to the extrication evolution necessary to risk assess 'roof fold down' on MPV's. To re-appraise yourself as to the crash detail and scenario for this paper exercise, I would ask the reader to revisit ISSUE 21 and refresh your memory. On Approach - The MPV vehicle on-its-side
The outer circle survey should begin on the approach to the crash and the inner zone as we walk around the vehicle. The order of risk mitigation will depend on how volatile it’s nature and the situation its presented in. For the purpose of this paper there are no surrounding risks and the only hazard that needs addressing is the vehicle itself. The following offers a good starting point – MPV Vehicle - Dynamic Risk AssessmentEnforce the Following Risk Control Measures (RCM) -

operational procedures and their pitfalls
In terms of firefighting safety the UK fire service is well ahead of their American counterparts. Distress Signaling Units and SCBA entry boards {Passport System), guidelines (search and tag lines) and emergency teams (Rapid Intervention Teams) have been in place for literally half a century. However it is refreshing to see how US firefighters are getting on with re-inventing the wheel. Don't get me wrong, I am a firm believer that these wheels need re-inventing, especially when they have been in place for a long time. 1959 - Introduction of BA entry control and procedures in the UK fire service Following a fatal fire in London's Smithfields meat market in 1958, much of the fire underground at basement level, two firefighters, Station Officer Jack Fort-Wells and Firefighter Dick Stocking, lost their lives when they became lost in smoke and were not missed by colleagues until it was to late to mount a rescue attempt - read history of Smithfield fire [CLICK] As a result of this incident, many valuable lessons were learnt. A tally system was introduced for each breathing apparatus set which meant that a record was kept whenever a set was worn. A purpose designed control board was used to enter the tallies and write vital information on; the firefighter's name, time he entered the building, wearer's location and the amount of oxygen the Proto BA set contained. From this information the entry board's controller entered an expected duration time and time of exit. In the event of an emergency, the controller would now be able to inform emergency crews where to locate overdue firefighters. This became the basis of all BA control procedures still followed throughout the UK and many Commonwealth Fire Services. Unfortunately these procedures, although they have been in practice for many years and to a degree served their purpose over time, they no longer address the real issues that threaten firefighters at larger fires. Hays Business Centre, Gillender Street, East London 1991 - Guide-lines / search lines One particular fire springs to mind The Hays Business Centre, Gillender Street, East London 10th July1991, where two firefighters, Terry Hunt and David Stokoe, lost their lives.. I followed the incident with great interest through the Coroner's Court, where a verdict of 'unlawfull killing' was returned and a H & S improvement notice, which resulted in the subsequent rewriting of guideline procedures. I attended the fire as one of the five crew members of one of London's Emergency Rescue Tenders (Dedicated Rescue Vehicle). Our team was responsible for extinguishing the fire with two lines of 45mm (1 3/4 inch) hose. Although it was a relatively small fire, one that beggared belief that it took the lives of two firefighters who became disorientated and lost in smoke, the building design resulted in it heating up like an oven. The warehouse was an old large 5 storey building that had been reconstructed internally, where metal mezzanine metal floors had been installed to increase floor space; in effect making the building seven floors. The premises was used as secure storage to archive bank and accountancy records, mostly paper in cardboard boxes and micro-fish files. All the windows in the building had been removed and glass-blocks cemented in place offering no natural ventilation to the premises. The first in crews were lured into a false sense of security as there was no smoke seen to be issuing outside the building. They entered the premises to investigate what could have been taken as a false alarm or a very small fire. On investigation they discovered the fire to be contained within a compartment. Being a large complex building, even with the fire alarm panel indicating the approximate area of fire, it took time to pin point the search, which ultimately delayed the initial attack on the fire. Smoke logging was apparent on the second floor mezzanine, but by the time many lengths of hose were stretched from the second floor dry-rising main, up the stairs to the second floor mezzanine, along a wire caged corridor; at which point an adaptor was added with a length of hose reel tubing (small bore hose), water was then laid on and an SCBA team entered the fire compartment area but by this time the actual fire could not be located. Heat and humidity got the better of them, so they withdrew. As the smoke logging and heat increased a 70mm (2 1/2 inch) hose line was laid from the street (due to the dry rising main leaking) to the entrance of the fire compartment but was never charged with water as smoke logging overtook the fire crew. The fire area was enclosed within brick walls, a concrete ceiling and metal flooring. Its area at that time was unknown. A make 'Pumps' 15 (15 fire trucks) was initiated and two further attacks were initialised at different points to fight the fire. Later, as the fire progressed, 'pumps' were made 20. In the meantime, due to the intensity of smoke logging, it was decided that a 4 firefighter SCBA crew would lay a main guide-line (Search line) from the ground floor entry point to the fire compartment area. The guide-line became snagged in its bag so it was tied off and a second line was then used to extend it. The SCBA crew's interface radio ceased to function but relying on the crew leader's personal hand-held radio, he decided to continue. A second SCBA team was then ordered to follow the initial guide-line and lay a branch line off to search the remainder of the 2nd floor mezzanine. The first team were never informed of this action. Due to severe smoke and heat and the inbred fear of flash-over, the second team became disorientated and mistakenly lay the branch line back on itself along the other side of the 2 metre (6 foot) wide corridor, back to the staircase at the entrance to the second floor mezzanine. Realising they had looped the line, they had the presence of mind to verify with entry control that this was the only staircase in this sector. They then exited the building. Aware of what they had done they reported it to entry control but the message was never relayed to the first team. On completion of their task the first team were retracing their way along the main guide-line where they discovered that the bag at the tie off point (where they had extended the main guide-line from) had come adrift and had spewed out the remainder of its contents on the floor. Suffering from the effects of severe heat and exhaustion, disorientated they followed the line; only to find that they had retraced their steps to the fire compartment. Again they made their way back along the guide-line to the bag tie off point where a disagreement broke out as each were convinced they knew the way out. Not thinking clearly the crew of 4 split into groups of two and went separate ways, At this point a vital message was sent, "We are lost on the main guide line - We have come to the branch guide line and whistles are going - Running low on air - Get CA men in", failed to trigger the correct response. Time was lost trying to contact the Incident Commander before the first Emergency Team (RIT) was committed. Just in the nick of time the emergency team found two of the guide-line team at the entrance to the 2nd floor mezzanine by the staircase. The team leader had just run out of air and was struggling to breath as they emerged at entry control. It was quite some time later when the other two were located and their bodies recovered. They had both run out of air and had removed their facemasks. The inside of the masks were sticky with oily deposits from the smoke and carbon deposits were later identified in their mouths and lungs. Their rescue was fraught with difficulty highlighting areas that had never been considered before. They became tangled up in the guide line, branch line and hose lines, and the corners in the corridors only added to their problems. First their SCBA sets became entangled and displaced, which made it necessary to remove them: then their turn-out coats slipped from their lifeless bodies as they were dragged along the corridors and down the stairs. The humidity could be likened to a steam bath. Please consider how hot it was. The heat was so intense that spalling to the concrete on the ceiling and supporting pillars was later very evident. During the time the fire was being fought and scalding condensed steam, which had nowhere to vent, was raining from the ceiling - no one could stand for long for fear of cooking, so the recovery of the two firefighters from the 2nd floor mezzanine had to be done on hands and knees. All these issues and the inherent dangers that can be associated with guide-lines have, to date, been overlooked. To meet the requirements of the H&S improvement notice, Operational Note 91 for guide-line procedure, was rewritten. Ostensibly it remained the same, no major changes were made but in the end everyone was satisfied; and that was the end of that! To this day the obvious areas that needed addressing continue to remain unanswered e.g. - Specialist training for emergency crews (RIT) - The correct time in events to lay a guide-line - What equipment should be carried by ET/ RIT - What minimum experience should teams have - What size should the crew be - What criteria for mobilisation should be adopted - What tell-tale signs should be monitoredNone of the guide-line crew activated their distress signaling units (DSU). Interestingly the Pathologist report noted that both firefighters' brains had swollen and were cherry red. Had this anything to do with the SCBA guide-line team's decision not to call for help sooner or activate their DSU's or is there some other underlining reason? Even the new automatic distress signaling unit (ADSU) that came about after this incident, fails to address the reluctance of manually sounding the personal alarm. Of course in a building as large as Hays Building Services, who could possibly have head them from outside. That was 17 years ago and the discussion and research still goes on. In 2002 the UK Fire Experimental Unit (FEU) were given the task of looking at better methods or ways of improving upon guide-lines. The study took them more than two years to complete and the end result concluded that the current guideline being `light, cheap and easily replaced' still offered the best solution. O come on, get real - think outside the box ! New search equipment and procedures are long overdue. What trials, if any, have been conducted with the following? -
Specialist training for emergency crews (RIT) Who should make up a rapid intervention team? How many firefighters should the team consist of? What training should be given and who should commit them? All valid questions, ones that presumable have been considered and answered long ago. In dealing with my second firefighter death at a ship fire way back in January 1980, I remember arriving on deck and finding nothing being done to rescue a missing firefighter. The appointed emergency team consisting of two recently appointed firefighters with less than one year's experience between them They were standing-by at entry control and fortunately had not been committed. The incident commander had lost the plot and insisted that it was too dangerous to attempt a rescue. Our ERT crew successfully carried out the rescue but unfortunately the firefighter was dead on recovery. The point here is two fold. 1.) The appointed 2 firefighter emergency team was hopelessly overwhelmed and 2.) the incident commander was too inexperienced to risk-assess and manage the situation accordingly. In the early part of my career it was normal for the ERT crew to form the emergency crew. The two inner London ERT's had a minimum of seven firefighters in the crew and the three outer London ERT's had five in each ream. The ruling was that these crews always worked as a team and were never split or reduced in number. These specialist vehicles attended all the larger fires and gained valuable experience and 'know how.' Over the years it became very obvious to me that ERT's were resented as they were perceived to steal the thunder from front line firefighters and officers. After the RudiM ship fire enquiry, our ERT crew were given 'Notes for file' (a reprimand), obviously to discourage us from disobeying a direct order. Some time after I was handed a confidential document which stated ERT crews has become a danger to themselves and were no longer necessary as all pumps carried a full rider position of SCBA. After that ERT's attendance were put on a request only basis for fires. With the exception of Gillender Street, we were never requested from there in. It took eight years and it was only after the enquiry into the Kings Cross fire in the London Underground in 1987, which took the lives of 31 people including a firefighter, that new rescue vehicles arrived. Now called Fire Rescue Units (FRU) they replaced the ERT's, and we were re-instated on all ship, basement and fires requiring 8 pumps and above. But by now, through lack of use and new team members who replaced those who had left or retired, the experience had been watered down Where would the fire service be without experience? The importance of training is obvious and a H&S mandatory requirement. So that we can grasp my point here we should appreciate that experience is not a requirement. With this highlighted in our minds we need to realise that the firefighting profession is different to say a plumber, electrician, builder etc., in so much as in these professions their skill level can be wholly imparted to them. A firefighter can only be instructed and trained in the basic rudimentary. Only operational experience and the inheritance gained from teamwork with the operationally blooded, educates the firefighter in recognising risk, risk analysis, how much you can push into a fire and what is safe and not safe. Although an imperfect science it's, never the less, the only way the firefighter can gain experience. However, one other thing qualifies all of this, the actual experience itself; and only then where good practice can be identified and bad practice corrected. In the Next issue - We will continue with entry control, guide line procedures and search line survival training; and discuss the estimation and potential of risks when searching in, around and above the fire. |

Addressing
The `Truck V’s Car problem' The positioning of the truck’s engine, whether it’s in front of the cab or cab over engine design has little bearing in the truck v’s car stakes. Ground clearance differential is the all important factor and the carnage cries out for a radical change in truck design. |
