I posted an article today @ SAFTENG explaining his accident pyramid model and discussing some of his Domino model. This quote is his own words trying to use the lottery to explain his pyramid model. I think it is a very fitting analogy. “The machine is dangerous as man makes it so. It is the […]
Another article defending the work of H. W. Heinrich, Assistant Superintendent Engineering and Inspection Division, The Travelers Insurance Company. I feel the need to explain how many have misstated Heinrich’s Accident Pyramid in this article. His Accident Pyramid is probably his most famous piece of work and by far what most attribute to his work.
First, let’s DEFINE what we mean when we use the term “remotely operated shutoff valve.” I have come to love the UK’s HSE definition, which is: A valve DESIGNED, INSTALLED, and MAINTAINED for the primary purpose of achieving rapid isolation of plant items containing hazardous materials in the event of a failure of the primary
“Proximate Causes and Subcauses (Personal).— In connection with the unsafe acts of persons (which are the direct causes of the majority of accidents) the immediately preceding subcauses are of great value in determining the most practical remedy. For example, it is not always enough to know merely that a machine operator oiled his machine while
H. W. Heinrich, Assistant Superintendent Engineering and Inspection Division, The Travelers Insurance Company is best known as the “Father of Industrial Safety”. Much of what he developed in the 1920s-1950s can still be applied today. He was a true pioneer in our profession, but it seems there are some in the profession today that want
Heinrich’s take on unsafe acts and the “vital significance” of what drove that behavior. He clearly believed that unsafe acts were a reflection of MANAGEMENT and not solely the worker. “Proximate Causes and Subcauses (Personal).— In connection with the unsafe acts of persons (which are the direct causes of the majority of accidents) the immediately
“The safety engineer referred to in this discussion is the industrial safety engineer who is employed by management. He is representative of and a part of the managerial and supervisory staff that directs the work of employees, and he, therefore, shares the responsibility of management for accident prevention as already described. Being specially qualified in
“Management’s responsibility for controlling the unsafe acts of employees exists chiefly because these unsafe acts occur in the course of employment that management creates and then directs. Management selects the persons upon whom it depends on carrying out industrial work. It may, if it so elects, choose persons who are experienced, capable of, and willing
H. W. Heinrich, Assistant Superintendent Engineering and Inspection Division of The Travelers Insurance Company, is known as the “Father of Industrial Safety.” But today, there is a movement in the safety profession to denounce his work. To me, this is just disrespectful; hell, most of us owe our professional safety careers to Heinrich. The work
Every business needs to risk rank its businesses down to each process within each facility. This “risk profiling” keeps safety matters and risks in perspective when you’re trying to manage a global operation. This risk profiling MUST use accurate and verified data. Lagging indicators can play a role, but they do not fully indicate risks.
Who said the following, and what year was it said? “The prevention of accidents is a science, but it is not so recognized nor is it treated scientifically today. In our endeavors to solve other problems we proceed logically enough to find out what is wrong and then to make it right; but when it
