A clear plastic bottle filled with water, exposed to the sun for 6 hours will make the water safe to drink (see the caveat list). In fact, the effectiveness of terminating harmful bacteria is an amazing 5-Nines, that is, 99.999 percent!

List of germs that are terminated from UV-A sunlight exposure at 6 hours

  • Bacteria – Escherichia coli
  • Bacteria – Vibrio cholera
  • Bacteria – Salmonella
  • Bacteria – Shigella flexneri
  • Bacteria – Campylobacter jejuni
  • Bacteria – Yersinia enterocolitica
  • Virus – Rotavirus
  • Parasites – Giardia
  • Parasites – Cryptosporidium (needs 10 hours exposure)

Important everyday carry for life and survival item one

June 17, 2019

You should never go anywhere without some type of cutting device. Whether it’s a pocket knife Anon folder, a fixed blade, nail clippers but some type of a knife or cutting device. This device can be used to help fashion improvised items in situations what do you need to cut a pizza, cut a sandwich in half, remove a splinter, cut off a pant leg or shirt, or defense. A knife is crucial

Weekly survival items to carry post

The number one item to carry and have with you is your mind in the knowledge of survival. Learn the rules of 3 if you don’t know those check the website mountain survival.com and determine those.

Old methods work

June 17, 2019

On a search a couple weeks ago the incident management team had to wait for a helicopter to get us a GPS location of an incident. They have forgotten old map navigation techniques called intersection.

Sometimes old procedures work better than new procedures

June 17, 2019

We had a fire in Reno and the incident management team had to wait for the helicopter to give them a a GPS location of where the fire was burning.

What’s interesting is that this could have been done instantaneously with the teams that were already out in the field by using a compass message called intersection.

Carry baby wipes

June 17, 2019

One item that’s a great accessory for your survival pack or even backpacking pack are baby wipes. These can clean a wound and clean yourself and keep you hygienically healthy when there’s lack of water.

Keep it easily accessible.

Drones in survival situations

The snow patrol drones saving skiers from an icy death

    Rescue team and droneImage copyrightROBODRONEImage captionRescue teams say drones can sometimes halve search timesBeing buried alive is a scenario most of us thankfully only experience in nightmares.But for off-piste skiing fans, lured by the thrill of carving their own tracks through fresh powder snow, it’s an ever-present risk.More than 150 people – mostly skiers, snowboarders and snowmobilers – are killed in avalanches every year, according to National Geographic statistics.This month alone, there have been deaths in Switzerland, Italy, Canada and North America.Drone manufacturers claim UAVs (unmanned aerial vehicles) could slash the toll by finding victims faster, and allowing ski patrollers to clear snow on high-risk slopes using explosives – without endangering themselves.

    Some mountain rescue services claim drones reduce their search times by up to 50%, because a drone can scan a large avalanche site more quickly than a person on foot.And when it comes to avalanches, time is of the essence.More than 90% of people buried by avalanches survive if dug out within 15 minutes. But after 45 minutes, the odds of survival drop to about 20%.Quadbike carrying droneImage copyrightROBODRONEImage captionThe Czech Mountain Rescue Service transports the Robodrone to the avalanche siteSuffocation is the main cause of death.”Once you’re trapped, you can’t move, even if you’re only under 10cm (4in) of snow, and carbon dioxide quickly builds up around your mouth,” says avalanche expert Henry Schniewind.For someone in this situation, the best hope of rescue is currently an avalanche transceiver. Worn under your jacket, these hand-sized radio devices emit a low-power pulsed signal when activated.They can also be switched to receive mode, allowing those skiing with avalanche victims to pinpoint the area where the signal is strongest, then use probes and shovels to dig them out.The Czech Mountain Rescue Service (MRS) uses Robodrone Kingfisher drones fitted with cameras and its own avalanche transceiver detection system to locate buried skiers.Drone against snowy treesImage copyrightROBODRONEImage captionThe drone, equipped with cameras and a transceiver sensor, can “talk” to the rescue team“We use drones fitted with a special system that works on the 457kHz frequency to detect avalanche transceivers,” says MRS drone operator Marek Frys.But finding someone’s exact location on difficult terrain often takes too long. New triple-antenna transceivers can help boost the signal, but what do you do about people who aren’t wearing any kind of transceiver?”We are working on thermal and multispectral systems that can see gases such as methane and carbon dioxide and could also detect people buried in mud slides, or under rubble,” explains Jean-Yves Barman, chief executive of software developer SCS Smart City Swiss.But finding people is one thing, digging them out is another. And no drones can yet do the digging.Rescue dogsImage copyrightROBODRONEImage captionDogs are still useful for digging out avalanche victimsThis is where dogs, fellow skiers and rescue teams are needed.”The goal is to find them and dig them out as fast as you can,” Mr Schniewind says.”That’s why most people who survive are saved by their companions rather than by organised rescue missions.”Other technologies come in.Some skiwear is now fitted with so-called Recco reflectors that bounce back a directional signal to mountain rescue teams equipped with a Recco detector.Roland Georges, president of the high mountain guides office in the French resort of Courchevel, says: “All the guides in Courchevel have Recco reflectors in their ski gear. However, it takes time to raise an alert and get a helicopter out.”Mr Georges believes drones could also become indispensible for mountain guides heading off the beaten track.”Having seen how small and quick to activate drones can be, I would not be surprised if all guides are soon carrying one,” he says.Presentational grey lineMany off-piste skiers also wear backpacks that incorporate avalanche airbags, designed to inflate when the wearer pulls a cord, and keep them on the surface of the snow.The latest innovations in this field include German airbag manufacturer ABS’s wireless partner activation system, that triggers all the bags in a group when one cord is pulled.ABS chief executive Dr Stefan Mohr says the technology can “remotely trigger partner airbags thanks to integrated wireless group activation, actively preventing the burial of more than one person”.And avalanche specialist Pieps has introduced an airbag that automatically deflates three minutes after being triggered so “the pressure on the buried person is reduced and a big air pocket is created”.But the essence of avalanche survival remains freeing those trapped as quickly as possible, Mr Schniewind says.Pascal SevozImage copyrightPASCAL SEVOZImage caption“Limiting avalanche danger is a big part of our work,” says Pascal Sevoz, director of piste services at Meribel-Mottaret in FranceSetting off controlled avalanches to prevent deadly slides happening in the first place is one of the main responsibilities of patrol teams working in ski resorts.”Limiting avalanche danger is a big part of our work,” says Pascal Sevoz, director of piste services in the French resort of Meribel-Mottaret.”The techniques we use to set off controlled slides include Gazex cannons – or metal pipes fixed to the side of the mountain on high-risk slopes – that explode a mixture of oxygen and propane, and Catex systems using cables along which explosive charges can be positioned.”It can be dangerous work.

However, it takes time to raise an alert and get a helicopter out.”Mr Georges believes drones could also become indispensible for mountain guides heading off the beaten track.”Having seen how small and quick to activate drones can be, I would not be surprised if all guides are soon carrying one,” he says.Presentational grey lineMany off-piste skiers also wear backpacks that incorporate avalanche airbags, designed to inflate when the wearer pulls a cord, and keep them on the surface of the snow.The latest innovations in this field include German airbag manufacturer ABS’s wireless partner activation system, that triggers all the bags in a group when one cord is pulled.ABS chief executive Dr Stefan Mohr says the technology can “remotely trigger partner airbags thanks to integrated wireless group activation, actively preventing the burial of more than one person”.And avalanche specialist Pieps has introduced an airbag that automatically deflates three minutes after being triggered so “the pressure on the buried person is reduced and a big air pocket is created”.But the essence of avalanche survival remains freeing those trapped as quickly as possible, Mr Schniewind says.Pascal SevozImage copyrightPASCAL SEVOZImage caption“Limiting avalanche danger is a big part of our work,” says Pascal Sevoz, director of piste services at Meribel-Mottaret in FranceSetting off controlled avalanches to prevent deadly slides happening in the first place is one of the main responsibilities of patrol teams working in ski resorts.”Limiting avalanche danger is a big part of our work,” says Pascal Sevoz, director of piste services in the French resort of Meribel-Mottaret.”The techniques we use to set off controlled slides include Gazex cannons – or metal pipes fixed to the side of the mountain on high-risk slopes – that explode a mixture of oxygen and propane, and Catex systems using cables along which explosive charges can be positioned.”It can be dangerous work. Just last month, two ski patrollers were killed in the French resort of Morillon when an explosive detonated before they could move away.Drone in mountain sceneryImage copyrightMOUNTAIN DRONESImage captionMountain Drones’ prototype can drop explosives to trigger avalanchesSo if drones could do this work, more lives might be saved.Mountain Drones, a Colorado-based start-up, has developed a prototype drone capable of carrying the charges used to trigger controlled avalanches, allowing humans to keep a safe distance away from the explosions.But the firm has hit a regulatory brick wall owing to the US government’s ban on drones carrying explosives.”Our technology is ready to go, but we’ve had to put development on hold because the federal government will not allow civilian operators to fly weaponised drones over US soil,” explains co-founder Brent Holbrook.”It seems we are a bit ahead of our time.”Follow Technology of Business editor Matthew Wall on Twitterand Facebook

      Sometimes old methods are better

      September 6, 2018

      In a search-and-rescue incident a couple weeks ago the management team waited for helicopter to get above the spot in order to get a GPS location.

      This location could have been determined in a lot quicker format using an older form of navigation called intersection.

      Sometime this old techniques are forgotten but they still work all you need is a a compass and where you are sighting from.

      What could have happened is we had teams out on location all viewing the incident area. They could have shot azimuths from where they were standing and radio these bearings to command. There are at least four teams viewing the incident. Through intersection which is with the four service used to do in determining Wildfire location, they would have had the GPS coordinate instantaneously and monitor the incident as the incident grew.

      The command simply had forgotten to use this old method and waited for Aviation team to fly above the area.

      The older method go to save time and money and given instantaneous location. Sometimes the older ways or better. They don’t rely upon mechanical or computer advantage in order to work.

      Keep this in your toolbox for future reference

      Perishable skills

      March 6, 2018

      Shooting accurately requires physical, mental, and physical/mental intersection skills. All of these skills decay, or perhaps the better word is atrophy, if they’re not maintained.
