Monday Accident & Lessons Learned: Freight Train Derailment in the UK – Three New Recommendations

July 18th, 2016 by

Screen Shot 2016 06 01 at 5 03 36 PM

Derailment of freight train near Angerstein Junction, south east London, 3 June 2015

At about 12:10 hrs on 3 June 2015, one wagon of an empty freight train derailed on the approach to Angerstein Junction, near Charlton in south east London. The train continued over the junction, derailing two further wagons, before it stopped on the Blackheath to Charlton line. The three derailed wagons were partly obstructing the line used by trains travelling in the opposite direction. No other trains were involved in the accident and no-one was injured, but there was significant damage to the railway infrastructure.

The wagons derailed because the leading right-hand wheel on one of them was carrying insufficient load to prevent the wheel climbing up the outer rail on a curved section of track. The insufficient load was due to a combination of the suspension on that wheel being locked in one position, a twisted bogie frame and an intended twist in the track.

As a consequence of this investigation, RAIB has made three recommendations.

The first, addressed to VTG (the wagon owner), seeks improvements to its wagon maintenance processes.

The second, also addressed to VTG, seeks liaison with industry to improve understanding of how wagon suspension wear characteristics relate to maintenance processes.

The third, addressed to Network Rail, seeks a review of infrastructure arrangements at the accident location.

The report also includes a learning point reinforcing a previous recommendation intended to encourage use of currently available wheel load data to enable identification of wagons with defects or uneven loads that are running on Network Rail’s infrastructure.

Is Discipline All That Is Needed?

July 6th, 2016 by

You’ve seen it hundreds of times. Something goes wrong and management starts the witch hunt. WHO is to BLAME?

Is this the best approach to preventing future problems? NO! Not by a long shot. 

We’ve written about the knee-jerk reaction to discipline someone after an accident many times. Here are a few links to some of the better articles:

Let me sum up what we know …

Always do a complete root cause analysis BEFORE you discipline someone for an incident. You will find that most accidents are NOT a result of bad people who lack discipline. Thus, disciplining innocent victims of the systems just leads to uncooperative employees and moral issues.

In the very few cases where discipline is called for after a root cause analysis, you will have the facts to justify the discipline.

For those who need to learn about effective advanced root cause analysis techniques that help you find the real causes of problems, attend out 5-Day TapRooT® Root Cause Analysis Training. See: http://www.taproot.com/courses

 

You are just one Causal Factor from your next major Incident. Can you prevent it?

July 5th, 2016 by

comic

Words that I hate to hear when asked to help with an investigation: “I am surprised this incident did not happen earlier!” Rarely have I seen an incident where there is not a history of the same problems occurring.  Think of it like a math equation:

X + Y (A) = The Incident

A company’s issues are just waiting for the right math equation to occur at the right time. What are some of the common factors that populate the equation above?

  • Audit Findings (risk or compliance)
  • Near Misses (or some cases, Near Hits)
  • OSHA Non-Recordable(s)
  • Defects (caught before the defect reached the customer)
  • Project Delays
  • Procurement Issues
  • Behavior Based Safety Entries

This list of variables is infinite and dependent on the industry and service or product that your company provides. Should you be required to perform a full root cause analysis on each and every write-up or issue listed above to prevent an Incident? Not, necessarily.

Instead, I recommend that you start looking at what would be a risk to employees, customers, environment, product/service or future company success if you combined any of your issues in the same timeline or process of transactions (in TapRooT® our timeline is called a SnapCharT®). For example, take the 3 issues listed below that have a higher potential of incident occurrence when combined in the right equation.

Issue 1: Audit finding for outdated procedures found in a laboratory for testing blood samples.

Issue 2: Behavior Based Safety Write-up entered for cracked and faded face shields

Issue 3: Older Blood Analyzer has open equipment work orders for service issues.

Combining the 3 items above could cause a contaminated blood sample, exposure of contaminated blood to the lab worker or a failed test sample to the patient.

If the cautions about your future combination of known issues are not heeded then please do not acted surprised after the future Incident occurs.

Monday Accident & Lessons Learned: WELL CONTROL EVENT WHEN USING AN MPD SYSTEM

July 4th, 2016 by

IOGP SAFETY ALERT

WELL CONTROL EVENT WHEN USING AN MPD SYSTEM

A High Pressure exploration gas-condensate bearing reservoir section was being drilled using automated Managed Pressure Drilling (MPD) and Rig Pump Divertor (RPD) equipment. Total gas and Connection Gas (TG/CG) peaks were noted the day before during drilling so the degasser was run. The drilled stand was backreamed at normal drilling flow rate prior to taking a MWD survey, making a connection and then taking Slow Circulating Rates (SCRs) on all 3 mud pumps. During taking SCRs an initial pit gain of 16bbl was noticed and reported.

It was suspected that pit gain was continuing, so a dynamic flow check was carried out in which it was confirmed that the well was flowing. Subsequently the well was shut in on the BOP (SICP=5,800psi, SIDPP=0psi). Dual float valves behind the bit were holding; total pit gain was estimated at 306bbls. Due to high casing pressure/MAASP concerns, an attempt was made to lower the annulus casing pressure by bleeding off gas through the choke and ‘poor boy’ mud-gas separator (MGS). This attempt was quickly aborted due to inadequate choke control leading to loss of the MGS liquid seal (SICP=7,470psi, SIDPP=0psi (floats holding).

After mobilization of high pressure bleed down facilities, the casing pressure was successfully reduced to zero psi through the “Lubricate and Bleed” well control method.

What Went Wrong?

During “pump off” events the Bottom Hole Pressure (BHP) dropped below Pore Pressure (Po) which resulted in initial small influxes into the wellbore. These were not recognized and therefore not reported as and when they occurred.

In MPD-RPD mode, fluid density dropped below the setpoint of 16.6 ppg (0.86 psi/ft) during pump off events (first and second survey and connections) due to a ‘sluggish’ RPD auto-choke. The RPD system had not been properly calibrated and the choke not run in the optimum position for effective control.

The formation pressure gradient of the gas-condensate bearing reservoir was evaluated to be 0.84psi/ft (Po~13,950psi).

NewImage

Corrective Actions and Recommendations:

  • Comprehensive and clear communication and action protocols (eg. close-in) should be tested, and verified as effective, across all Crews and Shifts.
  • Drillers must be clear that immediately on detecting an influx, they need to shut-in the well (applies for both MPD and non-MPD operations). The deployment of MPD does not change this basic principle.
  • Choke drills (A/B Crews and Day/Night shifts), including operation of remote choke(s) through a remote choke control panel, are critical to verifying that the total system (equipment, procedures, people including actions and communication protocols) are effective to operate the chokes against the maximum anticipated casing pressure.

Monday Accident & Lessons Learned: Derailment at Godmersham, Kent, UK

June 27th, 2016 by

 

 

Screen Shot 2016 04 16 at 4 54 57 PM

 

Here’s a summary of the report from the UK Rail Accident Investigation Branch about a derailment at Godmersham, UK:

 

“At around 21:40 hrs on 26 July 2015, a passenger train derailed after striking eight cows that had gained access to the railway at Godmersham in Kent, between Wye and Chilham stations. There had been a report of a cow on the railway an hour earlier, but a subsequent examination by the driver of the next passing train did not find anything. There were no further reports from other trains that passed before the accident occurred.

 

The train involved in the accident was travelling at 69 mph (111 km/h) at the point of impact. There were 67 passengers on board plus three members of staff; no injuries were reported at the time of the accident. Because the train’s radio had ceased to work during the accident, the driver ran for about three-quarters of a mile towards an oncoming train, which had already been stopped by the signaller, and used its radio to report the accident.

 

The accident occurred because the fence had not been maintained so as to restrain cows from breaching it, and because the railway’s response to the earlier report of a cow on the railway side of the fence was insufficient to prevent the accident. In addition, the absence of an obstacle deflector on the leading unit of the train made the derailment more likely.

 

As a result of this accident, RAIB has made five recommendations addressing the fence inspection process, clarification of railway rules in response to reports of large animals within the boundary fence, the fitting of obstacle deflectors to rolling stock (two recommendations), and the reliability of the train radio equipment.

 

RAIB has also identified two learning points for the railway industry, relating to the railway’s response to emergency situations, including the response to reports of large animals within the boundary fence and the actions to take following an accident.

Monday Accident & Lessons Learned: Collision between a tram and a pedestrian, Manchester

June 20th, 2016 by

Screen Shot 2016 04 12 at 12 51 33 PM

The UK Rail Accident Investigation Branch published a report about a tram hitting a pedestrian in Manchester, UK.

A summary of the report says:

At about 11:13 hrs on Tuesday 12 May 2015, a tram collided with and seriously injured a pedestrian, shortly after leaving Market Street tram stop in central Manchester. The pedestrian had just alighted from the tram and was walking along the track towards Piccadilly.

The accident occurred because the pedestrian did not move out of the path of the tram and because the driver did not apply the tram’s brakes in time to avoid striking the pedestrian.

As a result of this accident, RAIB has made three recommendations. One is made to Metrolink RATP Dev Ltd in conjunction with Transport for Greater Manchester, to review the assessment of risk from tram operations throughout the pedestrianised area in the vicinity of Piccadilly Gardens.

A second is made to UK Tram, to make explicit provision for the assessment of risk, in areas where trams and pedestrians/cyclists share the same space, in its guidance for the design and operation of urban tramways.

A further recommendation is made to Metrolink RATP Dev Ltd, to improve its care of staff involved in an accident.

Monday Accident & Lessons Learned: Everyday Hazard Analysis

May 30th, 2016 by

Here is a video with lessons learned about a fatal accident involving equipment (a scissor lift).

But there is an additional lesson that we can learn.

Every worksite should have a supervisor perform a quick Safeguard Analysis before people start work.

In this case, power lines were an obvious hazard (high voltage). And getting equipment with booms or lifts near them would cause the natural Safeguard (distance) to fail. If this Safeguard Analysis had been performed proactively, the worker could have been warned OR the actions (visually warnings and signage) could have been implemented to prevent the fatality.

Don’t wait for a fatality. Use TapRooT® to proactively prevent fatalities.

Would you like to learn to use TapRooT® to look for problems before accident, quality problems, and other failures happen? Then you should attend the upcoming TapRooT® for Audits Course on August 1-2 in San Antonio, Texas (just before the 2016 Global TapRooT® Summit on August 3-5). Register here:

Monday Accident & Lessons Learned: The Cost of an Accident – BP Pays Out $56 Billion So Far

May 23rd, 2016 by

The Wall Street Journal announced that BP incurred $56 Billion in expenses from the Deepwater Horizon explosion and spill. And the end is still not in sight.

BP’s CFO said “It’s impossible to come up with an estimate [of future costs].”

Of course, those costs don’t include the lives lost and the negative PR that the company has received. 

How much is a best in class process safety program worth? As BP’s CFO says …

It’s impossible to come up with an estimate.

If you would like to learn best practices to improve your safety performance and make your programs “best in class,” the at ten the 2016 Global TapRooT® Summit in San Antonio, Texas, on August 1-5.

What? You say YOUR COMPANY CAN’T AFFORT IT? Can it afford $56 Billion? The investment in your safety program is a pittance compared with the costs of a major accident. Your company should put spending on safety improvement BEFORE other investments … especially in difficult times.

If you are a senior manager, don’t wait for your safety folks to ask to attend the Summit. Send them an e-mail. Tell them you are putting a team together to attend the Summit with you to learn best practices to prevent major accidents. Ask them who would be the best people to include on this team. Then get them all registered fot the Summit.

Remember, the Summit is GUARANTEED

GUARANTEE

Attend the Summit and go back to work and use what you’ve learned.
If you don’t get at least 10 times the return on your investment,
simply return the Summit materials and we’ll refund the entire Summit fee.

Wow! A guaranteed ROI. How can we be so sure that you will return to work with valuable ideas to implement? Because we’ve been hosting these Summits for over 20 years and we know the “best of the best” attend the Summit and we know the value of the ideas they share each year. We’ve heard about the improvements that Summit attendees have implemented. Being proactive is the key to avoiding $56 Billion dollar mistakes.

So don’t wait. Get your folks registered today at:

Medical Errors – 3rd Leading Cause of Death in the US

May 4th, 2016 by

Medical Death Chart

Wow. Quite an eye-opening Washington Post article describing a report published in the BMJ. A comprehensive study by researchers at the John Hopkins University have found that medical mistakes are now responsible for more deaths in the US each year than Accidents, Respiratory Disease, and Strokes. They estimate over a quarter million people die each year in the US due to mistakes made during medical procedures. And this does NOT include other sentinel events that do not result in death.  Researchers include in this category “everything from bad doctors to more systemic issues such as communication breakdowns when patients are handed off from one department to another.”  Other tidbits from this study:

  • Over 700 deaths each day are due to medical errors
  • This is nearly 10% of all deaths in the US each year

What’s particularly alarming is that a study conducted in 1999 showed similar results.  That study called medical errors “an epidemic.”  And yet, very little has changed since that report was issued.  While a few categories have gotten better (hospital-acquired infections, for example), there has been almost no change in the overall numbers.

I’m sure there are many “causes” for these issues.  This report focused on the reporting systems in the US (and many other countries) that make it almost impossible to identify medical error cases.  And many other problems are endemic to the entire medical system:

  • Insurance liabilities
  • Inadequate reporting requirements
  • Poor training at many levels
  • Ineffective accountability systems
  • between patient care and running a business

However, individual health care facilities have the most control over their own outcomes.  They truly believe in providing the very best medical care to their patients.  They don’t necessarily need to wait for national regulations to force change.  They often just need a way to recognize the issues, minimize the local blame culture, identify problems, recognize systemic issues at their facilities, and apply effective corrective actions to those issues.

I have found that one of the major hurdles to correcting these issues is a lack of proper sentinel event analysis.  Hospitals are staffed with extremely smart people, but they just don’t have the training or expertise to perform comprehensive root cause analysis and incident investigation.  Many feel that, because they have smart people, they can perform these analyses without further training.  Unfortunately, incident investigation is a skill, just like other skills learned by doctors, nurses, and patient quality staff, and this skill requires specialized training and methodology.  When a facility is presented with this training (yes, I’m talking about TapRooT®!), I’ve found that they embrace the training and perform excellent investigations.  Hospital staff just need this bit of training to move to the next level of finding scientifically-derived root causes and applying effective corrective actions, all without playing the blame game.  It is gratifying to see doctors and nurses working together to correct these issues on their own, without needing some expensive guru to come in and do it for them.

Hospitals have the means to start fixing these issues.  I’m hoping the smart people at these facilities take this to heart and begin putting processes in place to make a positive difference in their patient outcomes.
