Face masks & coverings – on or off?

Face coverings are becoming part of the everyday outfit now for most European citizens. Many have been advised to wear these face coverings to protect yourself and others. The UK has just announced that they must too wear a face covering when go into a shop or supermarket or they will be fined. There are several arguments for and against’on or off’,
what do you think?

Here are a few of the outlined arguments against:

  • Wearing a mask may inhibit breathing for those who already have respiratory problems
  • Dirty masks (as people may not wash them) can help spread more germs
  • It makes people feel invincible and therefore defeats the object


Here are a few of the outlined arguments for:

  • Protect yourself and others from catching anything infectious
  • Duty of care to health workers to keep safe at all times
  • China has already had wearing masks as a norm – even stylish that now it is selfish to not wear a mask especially if you feel ill, plus protects people from pollution

Let us know your opinion in the comments…

YES – You find it MORE SAFE to travel now nearly everybody has to wear a face mask or covering
NO – Although other people wear face masks or coverings, you may feel this puts you off and won’t travel as it does NOT make you feel safer than before.

Let's talk liquid oxygen…

oxygen-1
When oxygen is in a cold state ( -183ºC), it turns to liquid. More oxygen molecules fit into the same space when in liquid form compared to when it is a gas and so liquid gas only takes up 10% of the space that compressed oxygen does. Therefore this liquid allows for a greater amount of oxygen to be placed in a tank and it weighs less than a compressed oxygen tank.
Liquid oxygen is stored in an insulated stainless steel low pressure container that works in a similar way to a Thermos flask. These base units store and hold the liquid oxygen at an extremely low temperature. As with the compressed oxygen, it can be filled into smaller units from the base unit so that it can be used portably.
Liquid oxygen doesn’t require power via electricity like oxygen concentrators do and also they make no noise.
There are some disadvantages in that liquid oxygen is more expensive than compressed oxygen and does not have as long of a shelf life as it will evaporate over time. Also, you will not be able to take liquid oxygen on a plane.
