Second in a series of five USAF safety training films dealing with general safety issues, with excellent graphics. Produced by Graphic Films of Los Angeles, where Douglas Trumbull (who did effects for "2001 a Space Odyssey") once worked.
"DESCRIBES MAN'S PHYSICAL LIMITATIONS AND RELATES THEM TO HUMAN ERROR ACCIDENTS. DELINEATES HUMAN FRAILTIES IN MOVEMENT, SOUND, VISION, BALANCE AND VERTIGO, TACTILE SENSITIVITY, PERCEPTION AND REFLEXES. RECONSTRUCTS SEVERAL ACCIDENTS TO SHOW THE CONSEQUENCES OF EXCEEDING ONE'S PHYSICAL CAPACITIES.."

Public domain film from the US National Archives, slightly cropped to remove uneven edges, with the aspect ratio corrected, and mild video noise reduction applied.
The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original).
Safety is the state of being "safe" (from French sauf), the condition of being protected against physical, social, spiritual, financial, political, emotional, occupational, psychological, educational or other types or consequences of failure, damage, error, accidents, harm or any other event which could be considered non-desirable. Safety can also be defined to be the control of recognized hazards to achieve an acceptable level of risk. This can take the form of being protected from the event or from exposure to something that causes health or economical losses. It can include protection of people or of possessions...
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. It is used in order to ensure that the object or organization will do only what it is meant to do.
It is important to realize that safety is relative. Eliminating all risk, if even possible, would be extremely difficult and very expensive. A safe situation is one where risks of injury or property damage are low and manageable.
Types of safety
It is important to distinguish between products that meet standards, that are safe, and those that merely feel safe. The highway safety community uses these terms:
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.
Substantive or objective safety occurs when the real-world safety history is favorable, whether or not standards are met.
Perceived or subjective safety refers to the users' level of comfort and perception of risk, without consideration of standards or safety history. For example, traffic signals are perceived as safe, yet under some circumstances, they can increase traffic crashes at an intersection. Traffic roundabouts have a generally favorable safety record yet often make drivers nervous.
Low perceived safety can have costs. For example, after the 9/11/2001 attacks, many people chose to drive rather than fly, despite the fact that, even counting terrorist attacks, flying is safer than driving. Perceived risk discourages people from walking and bicycling for transportation, enjoyment or exercise, even though the health benefits outweigh the risk of injury.
Also called social safety or public safety, security addresses the risk of harm due to intentional criminal acts such as assault, burglary or vandalism.
Because of the moral issues involved, security is of higher importance to many people than substantive safety. For example, a death due to murder is considered worse than a death in a car crash, even though in many countries, traffic deaths are more common than homicides...
