The Mine Hunters are on the search for sapphires. In this episode they head to South Western Madagascar, to one of the few places in the world where a single mine can produce sapphires of every color of the rainbow.
After a wall collapse, oxygen depletion is the biggest danger they face in these dangerous environments – tunnels which have been sealed off for some time, are long, narrow, and go deep under ground.
Unfortunately miner Fred runs out of Oxygen whilst inspecting the first muddy pit mine. His Tetra 3 gas detector goes in to alarm, allowing his friends to pull him out quickly and safely. Although the team here is on a budget, the one piece of kit they can not go without is clear – a life saving gas detector!
As part of our commitment to sharing our knowledge and expertise of gas detection safety around the world, we have created a series of short and to-the-point “factoid” videos, covering a variety of gas-related hazards. As with all our videos, they are intended to be watched, downloaded and/or shared however helps you. Please use them to spread the word and improve gas detection safety.
This first video focuses on risks associated with either too little or too much oxygen (O2).
A colourless and odourless gas, oxygen is an important part of the atmosphere and is necessary to sustain life. However, if levels become too high, it can become highly dangerous.
This week, we take a look at the dangers of high AND low levels of this everyday essential gas.
