W. Edwards Deming, a pioneer in the quality movement that occurred
 decades ago, succinctly described how a
 process works: inputs lead to outputs. In
 other words, companies are no better than
 how they perform a process, and they are
 fooling themselves if they believe the firm
 is doing well simply because of an absence
 of poor outputs.
 Businesses now scrutinize the inputs of
 a process and adjust accordingly through
 data-driven decisions to achieve continual
 improvement. While this has worked
 wonders for quality, many safety departments
 have yet to get the memo. A company
 can only measure how well it’s doing
 by focusing on leading indicators (inputs
 that can be observed and adjusted prior
 to an incident), as opposed to relying on
 lagging indicators that may not reflect
 what truly is happening. Many companies
 routinely collect leading indicators in the
 form of worksite inspections, observations
 of conditions and behaviors, and the mea 
 surement of activities. The next step is to
 conduct trend analyses instead of simply
 filing this information in a drawer, never
 to be seen again.
 Technology can help track and analyze
 this data, especially if it involves multiple
 projects across a large geographical area.
 Besides identifying the top hazards and
 the severity of risk posed by those hazards,
 several strong correlating metrics, called
 “safety truths,” also can be used to drive
 continuous safety improvement.   
MORE INSPECTIONS  The first safety truth relates to volume,
 with studies showing injuries decrease as
 observations increase. But keep in mind,
 companies can’t inspect process defects.
 With accident prevention as the goal,
 consider creating a health and safety plan
 that outlines what rules, policies, procedures
 and activities will be implemented.
 For example, before conducting hot work,
 a contractor must complete a hot work  
 permit. The permit details what must be
 done before the hazardous activity begins,
 such as removing or covering flammable
 materials, setting a fire watch and obtaining
 fire extinguishing equipment.
 Inspections simply show the gaps
 in what is expected and what actually
 occurs. How the data is acted on—from
 short-term fixes to long-term strategies—
 determines how much a process improves,
 which ultimately will reduce risks and prevent
 injuries.   
MORE INSPECTORS  The second safety truth involves the number
 and diversity of observers. Undoubtedly,
 more observers increases the chance
 of getting a more complete picture of risk.
 In addition, involving observers with different
 skill sets (i.e., the worker who performs
 the tasks daily versus the front-line
 supervisor with a wealth of experience)
 allows risk to be better identified and
 managed.  
 An observation is simply a snapshot
 in time. Depending on when employees
 observe something, their perception of risk
 can vary tremendously based on what they
 did or didn’t see. Often, companies with
 dozens of projects rely on one or only a few
 safety inspectors as the sole source of insight
 into risk, despite the fact that it could be
 weeks between each inspection. A recent
 study found that projects in which safety
 professionals were the only inspectors experienced
 the greatest number of incidents. 
 The reason lies in just one word: ownership.
 If safety personnel perform the inspections,
 then managers and workers will view the
 safety department as owning the process,
 instead of safety being a group effort.   
TOO MANY ‘ALL-SAFE’ INSPECTIONS The third safety truth involves the frequency
 of “100 percent” safe inspections. Research
 shows projects with a high frequency of allsafe
 inspections are generally at a very high
 risk for injuries.  
 The reasons observers may falsely indicate
 nothing is wrong vary from not knowing
 how to determine what is unsafe to fear
 of reprisal from management or fear that
 unsafe observations are perceived as poor
 job performance. If error, including human
 error, is viewed as a criminal act with penalty,
 no one would volunteer this information.
 Instead, companies should encourage a culture
 of discovery in which workers routinely
 are engaged and empowered to find and
 fix unsafe activities, as well as address the
 causal factors that allowed them to occur in
 the first place. This approach must be supported
 by leadership to remain effective and
 sustainable.   
TOO MANY UNSAFE OBSERVATIONS The fourth safety truth relates to reporting a
 high number of unsafe observations. Inaction
 can be quite frustrating for all parties, especially
 the employees who routinely spot the
 same hazards that fail to be resolved properly.
 Imagine if a worker observes a drywall
 contractor with terrible housekeeping,
 including scraps, screws and other debris
 strewn throughout the work area. Feedback
 is given to the foreman and eventually the
 mess is cleaned up. A day or two goes by
 and someone observes the same worker
 with poor housekeeping in another area of
 the project. The same feedback exchange
 occurs with minimal results. This can go on
 unless a strategic intervention occurs, which
 ensures accountability. Simply documenting
 the unsafe observation without addressing
 why it is happening won’t reduce injuries.
 Safety is a process—not simply a collection
 of mismatched programs and policy
 statements—that should be managed similarly
 to every other business function. When
 this is done, the evidence gained from observations
 should serve to predict and prevent
 injuries.
