![]() ![]() Traffic roundabouts have a generally favorable safety record yet often make drivers nervous. For example, traffic signals are perceived as safe, yet under some circumstances, they can increase traffic crashes at an intersection. Perceived or subjective safety refers to the users' level of comfort and perception of risk, without consideration of standards or safety history. Substantive or objective safety occurs when the real-world safety history is favorable, whether or not standards are met. Normative safety is achieved when a product or design meets applicable standards and practices for design and construction or manufacture, regardless of the product's actual safety history. ![]() The highway safety community uses these terms: There is a distinction between products that meet standards, that are safe, and that merely feel safe. 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. The safety provided is that daily medications will be supervised, the person will not need to engage in some potentially risky activities such as climbing stairs or cooking, and if the person falls down, someone there will be able to help the person get back up. For example, frail elderly people are sometimes moved out of their homes and into hospitals or skilled nursing homes with the claim that this will improve the person's safety. For example, a medication may be safe, for most people, under most circumstances, if taken in a certain amount.Ī choice motivated by safety may have other, unsafe consequences. When something is called safe, this usually means that it is safe within certain reasonable limits and parameters. A safe situation is one where risks of injury or property damage are low and manageable. Eliminating all risk, if even possible, would be extremely difficult and very expensive. It is important to realize that safety is relative. ![]() It is used in order to ensure that the object or organization will do only what it is meant to do. 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. Using this generic definition of safety it is possible to specify the elements of a security program. 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. Drawing from the definition of safety, then: This is where security science, which is of more recent date, enters. Some entity's steady state is challenged. In the world of everyday affairs, not all goes as planned. Using this definition, protection from a home's external threats and protection from its internal structural and equipment failures (see Meanings, above) are not two types of safety but rather two aspects of a home's steady state. It complies with situation-specific definitions of what is expected and acceptable. For any organization, place, or function, large or small, safety is a normative concept. “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. Safety is the condition of a “steady state” of an organization or place doing what it is supposed to do. When seen as unique, as we intend here, each term will assume its rightful place in influencing and being influenced by the other. This confuses the uniqueness that should be reserved for each by itself. Readers unfortunately are left to conclude whether they comprise a redundancy. With time the definitions between these two have often become interchanged, equated, and frequently appear juxtaposed in the same sentence. For example, home safety may indicate a building's ability to protect against external harm events (such as weather, home invasion, etc.), or may indicate that its internal installations (such as appliances, stairs, etc.) are safe (not dangerous or harmful) for its inhabitants.ĭiscussions of safety often include mention of related terms. There are two slightly different meanings of safety. Platform screen doors are primarily used for passenger safety ![]()
