From the Natural Resources Defense Council’s Report Preventing Hydrogen Explosions In Severe Nuclear Accidents: Unresolved Safety Issues Involving Hydrogen Generation And Mitigation

“The Nuclear Regulatory Commission is failing to meet the statutory standard of “adequate protection” of the public against the hazard of hydrogen explosions in a severe reactor accident.

After Fukushima Daiichi’s three devastating hydrogen explosions, the NRC decided to relegate investigating severe accident hydrogen safety issues to the lowest-priority and least proactive stage of its post–Fukushima Daiichi accident response.

NRDC believes that the NRC should reconsider its approach and promptly address severe accident safety issues involving hydrogen.”

Should You Attend the Global TapRooT® Summit if You’re Not TapRooT® Trained?

Posted: October 17th, 2013 in Courses, Root Causes, Summit

2012-TapRooT®-Summit-110.JPGIf you’ve been following our blog lately, you’ve noticed we’ve been busy preparing for the 2014 Global TapRooT® Summit (Horseshoe Bay, Texas, April 7 – 11, 2013).

You may have even considered signing up. I mean, who wouldn’t want to stay at the AAA Four Diamond Horseshoe Bay Resort (maybe even bring your spouse and enjoy it as a couple).

Who wouldn’t want to win great prizes, and enjoy a (literally) rock star Wednesday night reception?

And just how many chances in life do you get to meet and hear world-class speakers like Rocky Bleier?

But just when you were about to press the registration button, you thought:

Wait, I’m not sure I understand all there is to understand about TapRooT® Root Cause Analysis.
Since the TapRooT® folks are putting this together, shouldn’t I be TapRooT® trained before I attend?

First, if you are not TapRooT® trained, come to the 3-day Summit anyway.  Multiple tracks designed to share best practices within and across industries and professions make this event valuable to all. There are plenty of best practice session to choose from and you can create your own schedule if you don’t want to select a specific learning track.

And second, you can actually be TapRooT® trained before the 3-day Summit begins! We’re offering our 2-Day TapRooT® Incident Investigation & Root Cause Analysis Pre-Summit Course on April 7-8, 2014 as a Pre-Summit Course!

TapRooT® Techniques are designed for everyone from beginner to expert. In just two days, learn the TapRooT® Essentials to find and fix the root causes of incidents, accidents, quality problems, near-misses, operational errors, hospital sentinel events and other types of problems.

The essential TapRooT® Techniques include:

  • SnapCharT® – a simple, visual technique for collecting and organizing information to understand what happened.
  • Root Cause Tree® – a systematic, repeatable way to find the root causes of human performance and equipment problems — the Root Cause Tree® helps investigators see beyond their current knowledge.
  • Corrective Action Helper® – help lead investigators “outside the box” to develop effective corrective actions.

Using the TapRooT® System to find and fix the real root causes of problems keeps them from happening again and again.

So take our 2-Day course and then reinforce your new knowledge at the Summit by registering for the Incident Investigation and Root Cause Analysis Track. Make it a week of valuable learning that will contribute not only to your personal career development but also to saving lives and preventing injuries at your facility.

Interesting Article at the BST Web Site About Discipline and Safety

Posted: September 26th, 2013 in Human Performance, Root Causes

When many people first see the “enforcement NI” root cause on the TapRooT® Root Cause Tree®, they think that the obvious corrective action would be discipline. But those who read the TapRooT® Corrective Action Helper® know that there are reasons for people violating rules and that the only way to truly change behavior is to address the reasons why the rules are being broken.

The article, “The Five Pitfalls of Discipline in Safety,” clearly presents reasons why enforcement might need improvement. Click on the link and see if you agree.

Food Manufacturing Alert: Metal Objects Found in Doughnut . How Would You Investigate It?

Posted: August 27th, 2013 in Accidents, Current Events, Equipment/Equifactor®, Investigations, Medical/Healthcare, Pictures, Quality, Root Causes, TapRooT, Training

donut with foreign object

Material found in a doughnut, see the initial indications from the KAKE media article below.

A child is in a hospital bed at an Army Hospital after he took a bite of a glazed cake doughnut from a large retailer bakery. His mother says that the child said the doughnut tasted crunchy and then he chipped a tooth.

“There were pieces of black metal, some of them looked like rings, like washers off of a little screw, some of them were black metal fragments, like real sharp pieces,” says the mother.

The mother says that the child complained he had abdominal pains after swallowing the objects from the doughnut. Read the article here.

The retailer spokesperson said the company’s food safety team is looking into the incident, reaching out to the doughnut supplier and trying to figure out what happened. 

Now what? Is this a safety or quality issue or both?

If you were the retailer what would you do?

Would you quarantine the doughnutt and ask for access to the material found in the stomach? Would you be allowed?

If you were the doughnut supplier what would you do?

Would you look for similar batches and quarantine them? Would you inspect the batches or turn them over to the supply? Would you be allowed?

If you were the doughnut manufacturer what would you do?

Would you inspect the equipment used for this batch? Would you look for facility work order reports already completed or reported?

For all 3 parties, would you work together as one team to resolve the issue? What if you could not find any evidence on your side of missing parts?

Everything just discussed would be part of the analysis/investigation planning stage.  The first step of our TapRooT® 7 step investigation process. To learn more about what you would do following a problem, here are a few articles to learn more about are process and courses available.

f-15-e-00000019

By Chris Vallee

I was an aircraft mechanic in USAF when this incident occurred. The aftermath of the F-15 Crash and Pilot Fatality continued with an Airman’s suicide was loss to many.

While, I knew the basics, I just recently found a follow up report and wanted to share it. The information is taken directly from the article as is without my paraphrase. Here is the website.

An Air Force review board has partly cleared the name of an F-15 mechanic who committed suicide in 1996 rather than face a court-martial for a fatal repair error.

Evidence showed that TSgt. XXXXXX did not perform the botched control rod maintenance at issue, although he did check the work and found nothing wrong.

In addition, several previous incidents in which other mechanics made the same mistakes should have alerted the Air Force to a potential problem, according to the board.

“We did not think XXXX was totally free of all responsibility,” said Lee Baseman, chairman of the correction board. “But it was our view that he was unduly carrying the burden for a series of missteps that went back at least 10 years.”

In May 1995, XXXX and TSgt. YYYYYY were carrying out maintenance on an F-15C based at Spangdahlem AB, Germany, when YYYYY accidentally crossed flight control rods while reinstalling them. XXXX did not catch the miscue, which made the airplane impossible to control in the air. It subsequently crashed, killing Maj. Donald G. Lowry Jr. (Great GUY!!)

Air Force authorities charged XXXX and YYYYY with dereliction of duty and negligent homicide. XXXXX shot himself in October 1996 during a break in court proceedings. Commanding officers then accepted YYYYY request for administrative separation, on grounds that the interests of the service would be best served by bringing the tragic case to a swift conclusion.

Similar crossed-rod cases occurred at least twice before the Spangdahlem crash, noted the review board-once in 1986 and again in 1991. But in both instances the problem was caught before takeoff.

In its conclusions, the board stated, “After the Black Hawk shootdown [in 1994], the demand for accountability for this accident may have been pursued with such zeal as to leave fairness and equity behind. The fatal crash was a tragedy waiting to happen, yet the decedent was singled out to pay for an accident that could have been prevented anywhere along the ‘chain of events’ had any of the numerous individuals involved made different decisions.

“Most disturbing was the way the Air Force leadership allowed this case to be handled. The Air Force’s representatives resisted the inclusion of potentially exculpatory evidence from the review and report and managed to have a good deal of it excluded from consideration in the pending trial.”

Following the death of Lowry, the Air Force took steps to prevent such a mix-up from happening again. The control rods are now color-coded to ensure proper installation, and the maintenance technical manual warns against the mistake. All flight control systems must now be checked any time the control rods undergo maintenance. ” “

School Lunch and Water Poisoning in India… are the Root Causes Similar?

Posted: August 5th, 2013 in Accidents, Current Events, Investigations, Quality, Root Causes, TapRooT

With community protests after losing school aged loved ones, the Indian Government is closing in on suspected causes to include suspects. But is this a sign of Systemic Food Quality Control or as TapRooT® calls them “Generic Causes”? Will the nature of the investigations detour looking for Generic Causes by looking for blame instead?

Read below and ask, how would this be investigated or analyzed if it were in your hometown? What would be the response of the lunch cafeterias and Food on Wheels programs for the elderly and sick?

In a months time…..

23 students in the southwestern coastal state of Goa were treated at a hospital after they got sick at lunch

23 students died and 25 people were hospitalized from food poisoning after a school lunch in northern India’s Bihar state

Schoolchildren falling sick after drinking contaminated water from hand pumps continued for the third consecutive day on Saturday with at least 35 more students taken ill in different parts of Bihar.

Arrests made in two of incidents with possible cause  being insecticide poisoning; the water pump incident possibly criminal intent and the Bahir lunch room incident due to possible negligence.  The Goa incident not so clear in details yet.

Due to fear, large lunch producers temporarily shut down their lunch kitchens resulting in children not getting their mandated free lunches during school.

Consent Decree of Permanent Injunctions appear too frequent in FDA Regulated Industries, Why?

Posted: July 16th, 2013 in Performance Improvement, Quality, Root Causes, TapRooT, Training

Whether in the medical device, pharmaceutical or the food manufacturing industry, a company usually has had many violation corrective action chances before they get a consent decree of permanent injunction. At this point a third party reviews current deviations and often identifies a weak or non-existent root cause analysis program.

 

Now don’t get me wrong, this is often when our TapRooT® Root Cause Process gets recommended as a possible option and we gain a new client. However, I would prefer working with an FDA regulated company to develop effective corrective actions before they get in trouble. Or at least when they get their first FDA Finding.

 

Often FDA findings are found by an external audit.  To remain independent, the auditor turns over the findings through proper protocol and the company involved must provide proof that the causes were found and that the corrective action is effective. So if this protocol is followed, how did we get to a permanent injunction?  Can the repeat findings be purely an Enforcement Needs Improvement Root Cause for policies not followed?

 

I suggest Enforcement needs improvement is not the only problem.  To find out what your company might be missing in your RCA process. Find a course close to you and send one of your key quality or safety problem facilitators.  Here is our upcoming courses link: http://www.taproot.com/store/Courses/

Monday Accident & Lessons Learned: Just Say Root Cause Analysis Malpractice

Posted: May 20th, 2013 in Accidents, Investigations, Root Causes, TapRooT

The next time someone says they used 5-Whys to investigate an accident, just thing …

5-Whys = Root Cause Analysis Malpractice

Because 5-Whys is almost always root cause analysis malpractice. If you don’t believe it, assign someone who is good at 5-Whys to analyze a problem and someone who is good at using TapRooT® to analyze the same problem. Look at the results and you will see what I’m talking about.

That’s the lesson learned for today.

What is the Root Cause of Bad Science?

Everyone is interested in research statistics but the following infographic asserts that some scientists may make up the data, distort the data … even cook the data!

What would you guess is the root cause of bad science? The infographic suggests that one may be that the scientist changes results due to pressure from a funding source.

And what do you think about the ways to make research more honest at the end of the infographic? Would they work?

Root Cause Tip: What is “Behavior” and is it a “Cause” of an Accident?

Posted: March 13th, 2013 in Accidents, Human Performance, Performance Improvement, Root Cause Analysis Tips, Root Causes

Here’s the Meridian-Webster On-line Dictionary definition of “behavior”:

1. a : the manner of conducting oneself
    b : anything that an organism does involving action and response to stimulation
    c : the response of an individual, group, or species to its environment
2 : the way in which someone behaves; also : an instance of such behavior
3 : the way in which something functions or operates

Another definition that I think that management has in their heads is a “behavior” is:

“Any action or decision that an employee makes that management,
after the fact, decides was wrong.”

Why do I say that mangement uses this definition? Because I often hear about managers blaming the employee’s bad behavior for an accident.

For example, the employee was hurrying to get a job done and makes a mistake. That’s bad behavior!

What if an employee doesn’t hurry? Well, we yell at them to get going!

And what if they hurry and get the job done without an accident? We reward them for being efficient and a “go-getter.”

Management doesn’t usually see their role in making a “behavior” happen.

Behavior should NEVER be the end of a root cause analysis. Behavior is a fact. Just like a failed engine is a fact when a race car “blows it’s engine.”

Of course, a good root cause analysis should look into the causes for a behavior (a mistake) and uncover the reasons for the mistake and, if applicable, the controls that management has over behavior and how those controls failed when an accident occurred.

A bad decision or a human error that we call a “behavior” isn’t the end of the investigation … it is just the beginning!

TapRooT® helps investigator go beyond the symptoms (the behaviors) and find the root causes that management can fix. Some of the most difficult behaviors to fix are those so ingrained in the organization that people can’t see any other way to work.

For example, the culture of cost saving/cutting at BP was so ingrained, that even after the explosions and deaths at the Texas City Refinery, BP didn’t (couldn’t?) change it’s culture – at least not in the Gulf of Mexico exploration division – before they had the Deepwater Horizon accident. At least that is what I see in the reports and testimony that I’ve reviewed after the accident.

And with smaller incidents, it is even harder to get some managers’ attention and show them how they are shaping behavior. But at least in TapRooT® tries by providing guidance in analyzing human errors that leads to true root causes (not just symptoms).

Want to find out more about TapRooT® and behavior? Attend one of our 5-Day TapRooT® Advanced Root Cause Analysis Team Leader Courses. You’ll see how TapRooT® helps you analyze behavior issues in the exercises on the second day of the training. And you will learn much more. For a public 5-Day Course near you see:

Why Do People Have Problems Finding Root Causes? Read this Article – Under Scrutiny – from Quality Progress…

Posted: February 25th, 2013 in Performance Improvement, Quality, Root Cause Analysis Tips, Root Causes

Do you have problems finding the root causes of quality problems, safety incidents, or mechanical failures? It could be becuse of the root cause analysis tools you have chosen to use. Some tools have inherent weaknesses that are “built in.”

The article attached below (as first appeared in Quality Progress, the flagship magazine of the quality professional society ASQ), explains why some techniques commonly recommended for root cause analysis (like 5 Whys) will cause problems when applied by people in the field.

A Surefire Way to Keep Your Valentine’s Day Fun: Keep It Safe.

Posted: February 14th, 2013 in Medical/Healthcare, Performance Improvement, Root Cause Analysis Tips, Root Causes

The best way to keep your Valentine’s Day romantic and fun? Make food safety a priority!

A recent article on StateFoodSafety.com notes that the best restaurant to eat in on Valentine’s Day is a clean one. Here are a few of their food safety tips this Valentine’s Day:

  • Take note of the dining area and restrooms. If they do not meet cleanliness standards, it’s probably a good sign that the kitchen is also in need of more than just a light dusting. You might consider eating elsewhere for your own safety.
  • Only eat foods that are served to you hot. If the food is served to you at a lukewarm temperature, chances are that it was left sitting for too long and has allowed harmful bacteria to multiply.
  • Make sure the staff does not touch your food or the tips of your silverware with their bare hands. It’s probably not a good idea to let them sample your drink either.
  • Be wary of meat, eggs, oysters, or other raw foods that are undercooked.
  • Wash your hands properly before and after eating.

Why Can’t We Get Beyond Blame?

Posted: October 19th, 2012 in Current Events, Human Performance, Root Causes

R.R. Donnelley & Sons Co. prematurely filed Google Inc.’s earnings report with the Securities and Exchange Commission on Thursday.  Google’s earnings were supposed to be released after the stock markets closed at 3 p.m. Instead, they showed up on the SEC’s Edgar website about 11:30 a.m.  Google’s stock dropped as much as 11 percent, to $676 a share, before trading was halted about 20 minutes later at the company’s request.

About an hour after the earnings release, Google issued a statement blaming Chicago-based R.R. Donnelley for the blunder.

Root Cause Tip: Root Cause Tree Q&A

Posted: July 18th, 2012 in Root Cause Analysis Tips, Root Causes

TapRooT® Instructor, Michele Lindsay, answers a great question from one of the attendees of the 2-day TapRooT® Root Cause Analysis training course held at the 2012 Global TapRooT® Summit in Las Vegas, Nevada.

********************

Question from attendee:

I am presently using the techniques I learned to conduct my own RCA of the same incident we presented during the class and I had a question:

After grouping the conditions under each causal factor and working your way through the RCA tree on each causal factor, are you to only use the conditions grouped under that particular causal factor or are you allowed to use a condition that was grouped under a different causal factor?

My understanding is that you are to only use the conditions grouped under that specific causal factor and not reach out to other conditions from other “groups” as supporting evidence for the RCA.  I found during the class that the practice of using other conditions from other groups as supporting evidence to say either “yes” or “no” was occurring very often and that puzzled/troubled me.  In my opinion, if you were allowed to reach for other conditions not grouped under the causal factor in question, this negates the purpose of grouping conditions in the first place.  Am I wrong in my understanding of the purpose for grouping conditions?

Michele’s answer:

You are quite right that once conditions are grouped and Causal Factors identified, you really should stay within your “grouping” as you work through the RCA process.

Exceptions:
- if the condition was put in under one Causal Factor, but applies better to the another, consider moving the condition (the “so What” test helps with this) or put it both places if it applies in both. Theoretically, if it supports a Root Cause, the condition should be associated with that Causal Factor.

- if one is wandering out of a Causal Factor and “poaching” conditions to support the current Causal Factor being analyzed, when you read the question from the dictionary that you want to answer “yes” to, then add “and that’s why … (then insert Causal Factor here). If the answer is “no,” you are wandering off, if “yes,” move the condition over, if “no,” then don’t select the Root Cause.

If a team does wander off and poach conditions from another Causal Factor, you may see duplicated Root Cause, for the same reason (answered “yes” to the same question) in 2 RCA for different Causal Factors. During your sanity check at end of the process you should catch it.

So the purist in me agrees with your conclusion, but the tool is robust enough to handle good use and weaker use.

********************

Thanks for sending in the question and answer to share with others, Michele!

Monday Accident and Lessons Learned: When High Reliability Systems Fail

Posted: June 25th, 2012 in Accidents, Current Events, Equipment/Equifactor®, Investigations, Root Causes

What if you had a system with two regular power supplies, two back-up power supplies (diesels), and a battery back up with a separate diesel to keep it charged?

Wow!  This should be highly reliable right?

Read about how this system failed here:

Now here’s the question …

What did they miss in their “root cause analysis”?

I think they had great troubleshooting.

They even had actions to address generic problems.

But I don’t think they found the root causes of the “cloud failure” incident.
