Safety is the state of being "safe" (from French sauf), the condition of being protected from harm or other non-desirable outcomes. Safety can also refer to the control of recognized hazards in order to achieve an acceptable level of risk.
A man wants no protection when his conduct is strictly right.
William Murray, 1st Earl of Mansfield, Bird v. Gunston (1785), 3 Doug. 275; reported in James William Norton-Kyshe, Dictionary of Legal Quotations (1904), p. 212.
Protection and sustainable use of water supply is one of the most important environmental issues facing humanity. Groundwater is the primary source of drinking water for much of the world, as well as being vital for agriculture and industry, but it is under threat from pollution.
