Safety is the "condition or feeling of being safe".
Just about any endeavor can be performed safely.
- not "in danger; free from harm's reach",
- free "from risk; harmless; riskless",
- providing "protection from danger; providing shelter", or
- not "in danger from the specified source of harm"
is called safe.
Practical Safety can be defined as "anything done to prevent accidents or reduce their effects". It is generally a subject with much unnecessary confusion. Essentially, safety breaks down into 2 major categories:
Safety Technology: engineering solutions designed to eliminate / reduce hazards.
Safety Behaviour: defined safe actions using in conjunction with safety technology.
In order to control the design / input and to sustain both categories (voluntarily) Safety Management (application of management technques to control safety technology / behaviour) is necessary. The accepted world standard in this area is OHSAS18001. Templates are available to assist users in this endeavour, eg ISA2000. These can be certified by internationally recognized management systems certification organizations, eg ICS.
Safety Law: Statutory measures to enforce the above measures apply in most countries eg OHSA in the USA and EU law in Europe. Employers failing to adopt adequate safety management measures are liable to be prosecuted with resultant fines and possible imprisonment. Employers who do adopt such measures are likely to achieve significant savings in many areas of operation making them more competitive than their counterparts.

- a "condition of not being threatened, especially physically, psychologically, emotionally, or financially" or
- freedom "from apprehension"
is called security.
Def. a "likelihood of a negative [such as an unhealthy] outcome" is called a risk.
Evaluating a risk may mean assigning a probability of an unhealthy occurrence, e.g., an experimental repellor vehicle 10 km above the Earth's surface with only one repellor system may have a higher probability of crashing back to the ground than another with quadruple independent systems available to repel the Earth.
- Safety is conducting an experiment using 3300 coulombs in a capacitor and suffering no harm or radiation poisoning.
