Did you know? Explosive atmospheres
The Sun's main elements consist of 74% hydrogen and 24% helium.
The remaining 2% includes trace amounts of iron, nickel, oxygen, and all the other elements we have in the Solar System. In other words, the Solar System is mostly made of hydrogen. Eventually, the Sun will consume the Earth, when all the Hydrogen has been burnt out, the Sun will continue for about 130 million more years. During this time it will expand to the point that it will engulf Mercury and Venus and the Earth. At this stage it will have become a red giant.
Safety is a rising issue
In many industry sectors, combustible and potentially explosive atmospheres in the form of gases, vapours, mists or dusts are a present concern. The coal mining, chemical and petrochemical sectors are of particular concern, but the food industry, mill operation, wastewater and biogas production sectors are also affected.
These combustible substances can form a potentially explosive atmosphere when mixed with oxygen. The explosions occurring when this atmosphere is ignited can result in severe personal injury and/or damage to property. To prevent the risk of explosion, most industrialized nations have developed protective precautions in the form of laws, regulations and standards so as to achieve a high level of safety
