ASSE's Professional Safety Journal: A New View of the Great Safety Pyramid

DES PLAINES, Ill., Sept. 3, 2014 /PRNewswire-USNewswire/ -- Since its creation 83 years ago by H. W. Heinrich, the safety triangle offered a ratio formula that encouraged safety professionals to focus on the causes of minor injuries as a way to reduce the probability of having major accidents.  It sparked a new way of interpreting safety data that may be flawed.

Dave Rebbitt, author of the cover story "Pyramid Power" in the September issue of the American Society of Safety Engineer's monthly journal Professional Safety, makes the argument that the safety pyramid's assumptions are off base. Managing minor incidents only improves these types of incidents. It does not affect the major incident rate.  

"Attempts to apply a ratio or pyramid on a wide scale are not doomed because the concept is wrong, but because of the wide variation among industries and within individual companies," Rebbitt writes.

In 1931, Heinrich's safety pyramid was built around the ratio of 300-29-1: one serious injury was related to 29 minor injuries and 300 non-injury related events. Heinrich claimed 88 percent of incidents were caused by the unsafe acts of people, 10 percent were caused by unsafe conditions and 2 percent were unpreventable.

"Today, many believe that Heinrich's work was important, but superficial, and the numbers in the triangle questionable at best," Rebbitt writes. 

Heinrich's real contribution isn't in the ratio formula but in advocating for the use of data to find common causes as a function of injury investigations.  "Using ratios can identify trends and give early warning that something is outside the normal expected parameters," Rebbitt writes. "We should not dismiss these concepts or assumptions but understand what they mean to the profession today. The figures published by pioneers were meaningful to them, but forward-thinking professionals must make their own to keep things relevant and effective."

IoT is at the core or many Digital Transformation initiatives with the goal of re-inventing a company's business model. We all agree that collecting relevant IoT data will result in massive amounts of data needing to be stored. However, with the rapid development of IoT devices and ongoing business model transformation, we are not able to predict the volume and growth of IoT data. And with the lack of IoT history, traditional methods of IT and infrastructure planning based on the past do not app...
For far too long technology teams have lived in siloes. Not only physical siloes, but cultural siloes pushed by competing objectives. This includes informational siloes where business users require one set of data and tech teams require different data. DevOps intends to bridge these gaps to make tech driven operations more aligned and efficient.
For organizations that have amassed large sums of software complexity, taking a microservices approach is the first step toward DevOps and continuous improvement / development. Integrating system-level analysis with microservices makes it easier to change and add functionality to applications at any time without the increase of risk. Before you start big transformation projects or a cloud migration, make sure these changes won’t take down your entire organization.
It is ironic, but perhaps not unexpected, that many organizations who want the benefits of using an Agile approach to deliver software use a waterfall approach to adopting Agile practices: they form plans, they set milestones, and they measure progress by how many teams they have engaged. Old habits die hard, but like most waterfall software projects, most waterfall-style Agile adoption efforts fail to produce the results desired. The problem is that to get the results they want, they have to ch...
Organizations planning enterprise data center consolidation and modernization projects are faced with a challenging, costly reality. Requirements to deploy modern, cloud-native applications simultaneously with traditional client/server applications are almost impossible to achieve with hardware-centric enterprise infrastructure. Compute and network infrastructure are fast moving down a software-defined path, but storage has been a laggard. Until now.
Without a clear strategy for cost control and an architecture designed with cloud services in mind, costs and operational performance can quickly get out of control. To avoid multiple architectural redesigns requires extensive thought and planning.
