Only a Law can alter the terms of your sleep mindFly Katha

No person shall be deprived of his life or personal liberty except according to procedure established by law. Article 21 Indian Constitution 1950. The Hon'ble Supreme Court of India concurring opinion, stated that "it is evident that right of privacy and the right to sleep have always been treated to be a fundamental right like a right to breathe, to eat, to drink, to blink, etc.". We can conclude that the Sleep of crew members is a fundamental right protected by the constitution of India. Restriction can only be imposed on fundamental rights through a law or an act enacted by the state or central government. The act must pass the test of reasonableness and must not be arbitrary. unfair, whimsical or fanciful. “My mind clicks on and off…I try letting one eyelid close at a time while I prop the other open with my will. But the effort’s too much. Sleep is winning. My whole body argues dully that nothing, nothing life can attain, is quite so desirable as sleep.” Charles Lindbergh, describing the fatigue that struck him nine hours into his 33-hour solo Atlantic crossing. — Send in a voice message: https://podcasters.spotify.com/pod/show/safetymatters/message

  • The crash of the Boeing 777 on July 6th 2013, at San Francisco killed two and injured more than 180. The first police and fire personnel arrived at the crash scene in about two minutes, and local officials said brave rescue efforts and effective triage of the many wounded likely saved lives. A stark contrast was the Air India Express IX1344 accident at Calicut airport where the aircraft plunged 35 meters killing 21 people including the pilots. The victims were transported to various hospitals in ambulances and private vehicles. While ambulances are equipped with life saving medical equipment, the Co-Pilot was rushed to a hospital 25km away an hours drive on the backseat of a private car thereby depriving him of the critical life saving equipment. The rescuer narrates the way the co-pilot was extracted from the cockpit and that HE WAS ALIVE (READ HERE). While it was a helping gesture but who ever decided this inhumane treatment to the co-pilot did contribute to the sad demise of the young pilot. The airport emergency response plan which is mandatory and is rehearsed periodically failed miserably. A separate investigation to determine the effectiveness of the Airport & Airline Emergency Response Plan is also required to save as many lives in the future.
Probable route to the Hospital

The site of an aircraft accident is quite chaotic with multiple agencies rushing in to perform rescue, firefighting services. Emergency medical services (EMS) providers arrive on the scene of a mass casualty incident (MCI) and implement triage, moving green patients to a single area and grouping red and yellow patients using triage tape or tags. Patients are then transported to local hospitals according to their priority group. Tagged patients arrive at the hospital and are assessed and treated according to their priority.Stanford Hospital Emergency Management

Triage

  1. Triage is an inherent part of mass casualty response that prioritizes patients and the care they should receive based on the number and type of casualties and resources available. Triage is dynamic and ongoing, and not a discrete activity. The thoroughness of the patient assessment will vary based on scene safety, number of patients, personnel available to participate in the triage process, and other factors. Having scalable and flexible triage protocols allows providers to respond to any kind of incident.

Triage depends on a provider’s assessment and an interpretation of the patient’s prognosis based on that assessment (i.e., what care the patient needs and their estimated likelihood of survival), and what is required to deliver that care in terms of:

  1. Time – How much time is required to provide the interventions and how quickly does the intervention need to be initiated to be effective?
  2. Treater – How much healthcare provider expertise is required?
  3. Treatment – How many resources are required to achieve the desired outcome?

The Dutch emergency response plan which has handles the Turkish Air accident at Schipol Airport, Amsterdam lists out the following medico & equipment requirement.

A study compared the triage classifications with 2 clinical outcomes; Injury Severity Score (ISS) and the modified Baxt criteria, and hospital admission shown in Fig. below. The Baxt criteria consist of emergency interventions patients have undergone in order to treat acute life threatening injuries. Patients who met the Baxt criteria are considered P1. Patients who did not meet Baxt criteria but were admitted to hospital for at least 24 h were considered P2. Patients that did not meet Baxt criteria and were discharged within 24 h are considered P3. The processes of triage and different outcomes from prehospital and in hospital triage was evaluated. Overtriage was calculated by dividing the number of noncritical casualties triaged as P1, by the total number of P1 triaged casualties. Undertriage was calculated as the ratio of critically injured casualties, and casualties with an ISS  16 that were not transported to a level one trauma centre.

Conclusion of the study

After the Turkish Airlines Crash documentation of triage was minimal. According to the Baxt criteria there was a high percentage of overtriage (up to 89%), which can be desired in daily practice to minimise undertriage, but is less desirable in MCIs and disasters. Over- and undertriage did not result in an increase of mortality, since the critical mortality rate was 0%. The possible injuries sustained by the P3 casualties should not be underestimated, as major injuries were diagnosed in this group. In an airplane accident, such as described in this study, spinal immobilisation should be considered for transport of all survivors.

After the Turkish Airlines Crash the first reports of the accident came into the Emergency Services Centre (ESC) one minute after  the crash at 10:27 a.m. Eighty two ambulances from different regions were dispatched, as were the medical officers and 3 Helicopter Emergency Medical Service teams. 

Response time at Calicut

The location of the air traffic control tower at Calicut is towards the approach end of where the ill-fated aircraft arrived and further away from the crash site. The height of the control tower is lower than usual since the runway is higher than the apron where the tower is constructed. It is highly unlikely that the air traffic controllers could have noticed the the aircraft had met with an accident that rainy night.

The airport rescue fire services are expected to reach the accident site within 3 minutes of receiving the alert. The rescue services probably reached between 12-15 minutes after being informed. Since the air traffic controllers did not have direct view of the location, they would have been informed by the security guards at the airport perimeter via their reporting chain. The time taken for the airport rescue fire services to reach the accident site could have been as much as 30 minutes from the time of the accident. This is owing to the probability that the fire tenders rushed to the far end of the runway where they expected the aircraft to be located. However, the aircraft had slid down and there was no direct access. The fire tenders would have to rush back to where they started and take the perimeter road to the accident site.

Probable route taken by the Airport Rescue Fire Fighting Services

The local fire tenders were seen in media footage spraying water on the aircraft fuselage whereas foam is the recommended fire retardant agent for aircraft accidents. This is a proof that the local fire and rescue services were active and uncharge before the airport services and emergency response was activated.The triage was in all probability not implemented and the co-pilot unfortunately was put in the back seat of the private car by people who were not aware of segregation of casualties based on the medical status of the individual.

A precious life which could have been saved by providing timely medical intervention was lost due negligence.

Philadelphia Scoop and Run

Philadelphia in the USA has a high number of gunshot victims every year and a number of them are saved by police officers transporting the victims in the back seat of their cars. According to some trauma doctors, the lack of medical intervention that victims receive during the typical scoop and run is part of what makes the practice beneficial. Advanced procedures like breathing tubes and IV fluids, while helpful for certain kinds of patients, may actually do more harm than good for shooting and stabbing victims in urban areas. “I’d love to debunk the myth that you need a person on the scene who has all this advanced medical training and that is going to make the difference for this specific kind of injury,” says Dr. Elliott Haut, a Johns Hopkins trauma surgeon. For a presentation he gives at conferences, he shows a slide that asks what’s the best fluid to give victims of penetrating trauma. Then he clicks to the next slide, which reads “diesel fuel.” Haut says, “Yes, you’re going to get less medical care on the street and in the back of the car, but I’m OK with that because the shorter time is going to make a difference.”

This works when medical care is available within 4 minutes to drive from the accident site and not an hour drive as was the case of the AirIndia Express Co-Pilots.
