'DISCUSSES THE NEED FOR A BETTER UNDERSTANDING OF COMMUNICATION AND ITS IMPORTANCE IN PREVENTING ACCIDENTS. POINTS OUT HOW ABILITY TO IMPART INFORMATION AND SHARE KNOWLEDGE CAN CONTRIBUTE TO A REDUCTION IN ACCIDENTS. DISCUSSES THE VARIOUS MEANS OF COMMUNICATION THAT RANGE FROM ORAL AND WRITTEN EXPRESSION TO MAN-MACHINE INTERCOMMUNICATION. REENACTS SEVERAL ACCIDENTS TO SHOW CONSEQUENCES OF TOO MUCH OR TOO LITTLE INFORMATION, GARBLED AND UNCLEAR MESSAGES, AND EMOTIONAL DIFFICULTIES.'
Originally a public domain film, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & 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 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...
Risks and responses
Safety is generally interpreted as implying a real and significant impact on risk of death, injury or damage to property. In response to perceived risks many interventions may be proposed with engineering responses and regulation being two of the most common.
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.
System safety and reliability engineering
System safety and reliability engineering is an engineering discipline. 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. A knowledge of the literature, the standards and custom in a field is a critical part of safety engineering. A combination of theory and track record of practices is involved, and track record indicates some of the areas of theory that are relevant. (In the USA, persons with a state license in Professional Engineering in Electrical Engineering are expected to be competent in this regard, the foregoing notwithstanding, but most electrical engineers have no need of the license for their work.)
Safety is often seen as one of a group of related disciplines: quality, reliability, availability, maintainability and safety. (Availability is sometimes not mentioned, on the principle that it is a simple function of reliability and maintainability.) These issues tend to determine the value of any work, and deficits in any of these areas are considered to result in a cost, beyond the cost of addressing the area in the first place; good management is then expected to minimize total cost...
