Lack of oxygen in confined spaces. Lack of breathable air in confined spaces is one of the commonest reasons for accidents where there are multiple deaths among welders and other maintenance workers.

Money is what people use to buy things and services. Money is what many people take for selling their own things or services. There are many kinds of money in the world. Most countries have their own kind of money, such as the United States dollar or the British pound. Money is also called many other names, like currency or cash. Most of the time a state or a government prints paper money and makes coins at a mint.
By using a copper core covered in a silver coating, the coin has a much lower intrinsic value, while face value remains the same. Counterfeit money is imitation currency produced without the legal sanction of the state or government. Producing or using counterfeit money is a form of fraud or forgery. Counterfeiting is almost as old as money itself. Plated copies (known as FourrÃ©es) have been found of Lydian coins which are thought to be among the first western coins.
