"What it is supposed to do" is defined in terms of public codes and standards, associated architectural and engineering designs, corporate vision and mission statements, and operational plans and personnel policies.
Drawing from the definition of safety, then: Security is the process or means, physical or human, of delaying, preventing, and otherwise protecting against external or internal, defects, dangers, loss, criminals, and other individuals or actions that threaten, hinder or destroy an organization’s "steady state," and deprive it of its intended purpose for being.
[3] Safety can be limited in relation to some guarantee or a standard of insurance to the quality and unharmful function of an object or organization.
However, the end result might be decidedly unsafe, including the dangers of transfer trauma, hospital delirium, elder abuse, hospital-acquired infections, depression, anxiety, and even a desire to die.
[9] Safety is generally interpreted as implying a real and significant impact on risk of death, injury or damage to property.
Probably the most common individual response to perceived safety issues is insurance, which compensates for or provides restitution in the case of damage or loss.
Continuous changes in technology, environmental regulation and public safety concerns make the analysis of complex safety-critical systems more and more demanding.
A common fallacy, for example among electrical engineers regarding structure power systems, is that safety issues can be readily deduced.
In fact, safety issues have been discovered one by one, over more than a century in the case mentioned, in the work of many thousands of practitioners, and cannot be deduced by a single individual over a few decades.
[10][11] The goal of this research is to identify, understand, and mitigate risks to human health and well-being in various environments.
This involves systematically studying hazards, analyzing potential and actual accidents, and developing effective strategies to prevent injuries and fatalities.
Safety research aims to create safer products, systems, and practices by incorporating scientific, engineering, and behavioral insights.
Ultimately, it seeks to enhance public safety, reduce economic losses, and improve overall quality of life by ensuring that both individuals and communities are better protected from harm.
They are also Accreditation Bodies and entitle independent third parties such as testing and certification agencies to inspect and ensure compliance to the standards they defined.
For instance, the American Society of Mechanical Engineers (ASME) formulated a certain number of safety standards in its Boiler and Pressure Vessel Code (BPVC) and accredited TÜV Rheinland to provide certification services to guarantee product compliance to the defined safety regulations.
Usually, members of a particular industry will voluntarily form a committee to study safety issues and propose standards.
