Oxygen Supplies In Disaster Management

The title of this post is the same as this peer-reviewed paper on PubMed.

This is the Abstract.

Mass casualty events and disasters, both natural and human-generated, occur frequently around the world and can generate scores of injured or ill victims in need of resources. Of the available medical supplies, oxygen remains the critical consumable resource in disaster management. Strategic management of oxygen supplies in disaster scenarios remains a priority. Hospitals have large supplies of liquid oxygen and a supply of compressed gas oxygen cylinders that allow several days of reserve, but a large influx of patients from a disaster can strain these resources. Most backup liquid oxygen supplies are attached to the main liquid system and supply line. In the event of damage to the main system, the reserve supply is rendered useless. The Strategic National Stockpile supplies medications, medical supplies, and equipment to disaster areas, but it does not supply oxygen. Contracted vendors can deliver oxygen to alternate care facilities in disaster areas, in the form of concentrators, compressed gas cylinders, and liquid oxygen. Planning for oxygen needs following a disaster still presents a substantial challenge, but alternate care facilities have proven to be valuable in relieving pressure from the mass influx of patients into hospitals, especially for those on home oxygen who require only an electrical source to power their oxygen concentrator.

The Covid-19 situation in India, may be a total different type of disaster, but what is happening in the country is having the same outcome – A serious lack of medical oxygen!

It should not be forgotten, that we nearly had serious oxygen problems last year in the UK.

A Possible Solution

I feel we need to develop a reliable oxygen system that can supply large amounts of medical grade oxygen, which can be delivered quickly and easily to site.

Could The System Be Electrolyser-Based?

I feel that this could be an a possibility.

  • Electrolysers need just a water and electricity supply.
  • They produce both hydrogen and oxygen.
  • If the hydrogen isn’t wanted it can be added to the gas main.

Electrolysers may offer size, safety, weight and other advantages in difficult environments.

The System Must Be Air-Transportable

This would be absolutely essential amd as the equipment might be flying into a serious disaster, surely it would be preferable if it could be fitted into a Hercules.

Conclusion

As I write this post, this article on the BBC has just been published, which is entitled UK Sends Supplies To India Amid Record Virus Surge.

This is an extract.

The assistance package includes 495 oxygen concentrators – which extract oxygen from the air to give to patients – as well as ventilators.

India is seeing thousands of deaths a day amid oxygen shortages.

Will that be enough?

We certainly must be as well-prepared as we can.

‘Super Train’ In Finland Sets New Record: The Equivalent Of 92 Trucks

The title of this post, is the same as that of this article on RailFreight.com.

This is the introductory paragraph.

The Finnish railway company VR Transpoint has introduced another heavy weight to the railways. Dubbed the Super Train, it carries a weight of 7,000 tonne, and 80 wagons. Moreover, it is about one kilometre long. According to the company, this sets a new record on Finnish railways.

These are a few points about the service.

  • The service runs between Vainikkala and Hamina.
  • The route appears to be electrified.
  • The super train is hauled by two Vectron locomotives.
  • Longer trains are more efficient.
  • Long trains regularly run in Russia.

This map shows the border crossing at Vainikkala.

Note.

  1. The border running South-West and North-East across the map.
  2. The giant Finnish marshalling yard in the North-West.
  3. The large Russian marshalling yard in the South-East.

This Google Map shows the Finnish Marshalling yard at Vainikkala.

I estimate that the yard is over a kilometre in length.

Passenger Trains Between Helsinki And St. Petersburg

There is also a passenger service between Helsinki and St. Petersburg, that uses this route called Allegro, that usually runs thrice daily.

The trains are Alstom Pendolinos, specially designed for the route and are detailed in this section called Vehicles in the Allegro Wikipedia entry.

The journey time is just three and a half hours.

If you want to buy tickets, this page on The Man In Seat 61 gives all the details.

Conclusion

It looks like the Finns and the Russians have co-operated well to create a quality passenger and freight link between their two countries.
