Having trouble breathing?
Oxygen concentrations fall as altitude increases, so the body has to breathe more to boost the amount of oxygen being carried by haemoglobin in red blood cells. People unused to the thin air can find themselves short of breath, a condition called hypoxia which, in extreme cases, can cause potentially fatal altitude sickness. People indigenous to high altitudes - some 3.5 km and higher - have adapted to the lower concentrations of oxygen in different ways. Natives of the Andes mountain range in South America have a higher concentration of haemoglobin in blood, to allow more oxygen to be taken up and carried - compensating for the lower amount of oxygen in the air.Life-Support
The “fast-acting” threats come in the form of poison gas (man-made or natural). The growth of thechemical industry has increased the potential for this hazard greatly.

There is conclusive evidence backed by third party investigation that the tragedy was caused by employee sabotage. The state government of Madhya Pradesh in its official documentation of deaths and injuries reported that approximately 3,800 persons died.”Examples of Fast-Acting airborne toxics
