Accidents Don't Just Happen
By Terry Schweitzer, GBB Vice President

Collection Truck

Vehicle accidents and personal injuries do not just happen and should not be assumed to be an integral part of the occupation costs of collection, disposal or recycling. Plain and simple - accidents are caused by humans. Herbert W. Heinrich was an American industrial safety pioneer who published a book titled "Industrial Accident Prevention, A Scientific Approach" in 1931. He determined that in a workplace, for every accident that causes a major injury, there are 29 accidents that cause minor injuries and 300 accidents that cause no injuries. Frank Bird, a US safety researcher, also concluded that there are another 600 near misses per major accident. No matter what theory you subscribe to, there is a correlation that continued unsafe acts will eventually lead to serious accidents and fatalities.


What is the common thread with all this? Human behavior. Some experts in the field of safety claim Heinrich's work as the basis for the theory of Behavior-based safety. They feel that as many as 95 percent of all workplace accidents are caused by unsafe acts: taking shortcuts, being over confident, beginning a task with incomplete instructions, poor housekeeping, ignoring safety procedures, mental distractions, and failure to plan.


One approach for reducing accidents involves understanding organizational weaknesses. We must rationalize that unsafe behavior does not occur on its own in organizations; the unsafe behavior was caused by the organization itself. An organization must get past the what, when, where and how an accident happened and understand why it happened. Underneath every human cause lies a deeper cause called latent causes.


As example, while I was District Manager for a solid waste collection company, we had a driver shortage. We decided to put our "best" driver with our two "best" helpers and give them two routes because we knew they could "bang it out." While on route, a needle stuck one of the helpers on that crew while collecting garbage. We conducted a Latent Cause Analysis (LCA) and understood that 1) accidents and injuries are not a part of doing business; 2) management was indirectly contributing to safety failures by our actions and words; and 3) safety failures, including unreported unsafe acts, were trying to tell us something. We learned that we did not always think about safety in our decisions and were more focused on productivity, and communicated as such with front-line employees. We eliminated the use of "speed" words such as fast, hurry and quickly, and replaced them with safety and efficiency words. We aligned our actions with safety, instituted daily safety briefings, and empowered employees to report unsafe conditions. The LCA findings changed the mindset of all the employees, dramatically reducing unsafe acts and accidents.


Accidents don't happen, they are caused by humans. It's important to realize that the cause can be organizational; where the organization directly or indirectly influences employees to take shortcuts. It is important that management/supervision be constantly aware of how it acts and directs employees to work safely. By conducting a LCA whenever a safety failure occurs, the organization can change human behaviors and prevent accidents.Leaf bullet

Small Scale Waste-to-Energy Project Considered by the Metlakatla Indian Community, AK

MetlakatlaIn April 2015, through a formal procurement process, the Metlakatla Indian Community (MIC) selected GBB to evaluate the feasibility of a small scale waste-to-energy (WTE) facility as part of their Solid Waste Management Plan (SWMP) update for which they had received a grant from the U.S. Department of Interior. The MIC's aim was to evaluate WTE technologies that offer an affordable solution providing local jobs, creating energy, and capable of processing at least 5 tons per day of MSW as currently generated, with an allowance for feedstock increase to around 10 tons per day.


After a site visit, in southeast Alaska, and a review of the existing plan, the GBB Project Team headed by Senior VP John Carlton, P.E., BCEE, provided guidance in updating the SWMP and investigated recycling options. As part of the effort the team reviewed and considered small scale WTE strategies that would reduce or eliminate the need for the municipal dump and create energy (electricity, heating or cooling) for MIC facilities such as schools, medical clinic, and fish plant. This led to the next step in which the GBB Project Team prepared and published a Request for Expression of Interest and Qualifications for the small scale WTE system. In late November, the GBB Project team presented its report, including economic evaluations of three scenarios and recommendations, at the MIC Special Session of Tribal Council Meeting. The MIC is currently evaluating its options.Leaf bullet
