Effect of the weather in gas attacks (Page 3 of 59)
The danger from gas is increased or decreased according to the weather.
Calm Mild Weather (with or without fog). Gas evaporates slowly. It hangs about in strong concentration and may penetrate buildings if these are imperfectly protected.
Warm Weather. Gas is given off more readily and mixes more easily with the surrounding air.
Cold Weather. Gas does not rise so quickly.
Frosty Weather. Has little effect on non-persistent gas, but may cause the liquid of mustard gas to freeze, which remains a danger if touched. It will give off vapour again when the thaw sets in.
Rain. Has little effect on any gas if light in character, but if heavy rain occurs it will remove the gas from the air and also wash away the liquid from the ground.
Wind. A high wind will soon carry away the gas, as well as the vapour arising from the liquid on the ground, etc. The rate at which this happens depends largely on the force and direction of the wind. The gas rarely rises to more than 20 feet.
I always believed that my Grandfather died in France, close to home and the Wingate coal mines.
Recently, I came across a letter that my Mother wrote. 'Dad was MIA Dardanelles!!!'
Not France???
He was 'recovering' from the effects of the coal dust with not a bright future ahead of him, or the family, health wise on all fronts. With his last gasp he volunteered to go overseas.
