The FORKLIFT 500 – A Need for Speed

From a young age, many children are typically drawn to things that are fast.  Fast toys, fast race cars, sports that require speed.  Is it possible that “feeding” this desire tends to make many of us resist, whether consciously or subconsciously, the request or demand to “Slow down!” once we’ve grown up, even when we know that it is the right and wise thing to do?  Now couple this with the natural tendency of most businesses to push for more productivity by doing things faster and more efficiently.  This can be dangerous when we take this combination into a workplace where forklifts are a necessary and integral part of the day-to-day operations.

Race cars are designed to go fast, and they rely on a properly trained and experienced driver to complete a race successfully and safely.  Forklifts are designed to lift and transport heavy loads, and they also rely on a properly trained and experienced driver to Read More

Danger Within Reach

Author

How far away from a hazard should you stay?  Your parents or grandparents would probably have told you to stay far away, but what are you to do when a hazard is present, and you must work around or near the hazard?  And what exactly is a hazard?  ISO 12100 Safety of machinery – General principles for design – Risk assessment and risk reduction defines a hazard as a “potential source of harm.

Where would a designer of a machine or product start if they wished to protect the user from a known hazard?  Consensus standards are a great place to begin the quest for safety. Read More

Financial Injury.…From a Machine?!?!

Author

Forensic engineers may be called upon to investigate a broad array of problems concerning a machine.  Cases involving physical injuries and even death are a large part of what we investigate in order to determine what caused the accident to happen and who may be at fault.  Occasionally, problems with a recently designed custom machine do not cause a physical injury, but instead cause a “financial” injury.  This type of “injury” can negatively impact the machine designer, the machine purchaser, or possibly both.  Financial injuries can be quite substantial, just as physical injuries can be, and may severely impact a company’s cash flow which can make or break a company.  A refusal to pay a designer/builder of a machine or paying for a machine that ends up not meeting the agreed upon performance specifications can have catastrophic consequences for many businesses, especially for small ones.

The Collision Reconstruction Matrix

Author

It’s mid-January, the high today is 28 degrees with lows in the teens as the Carolinas are in the grip of a Canadian cold front and I’m on call tonight. The phone rings at 3:00 am; yes Sir, three cars with two fatalities, I-85 northbound, yes Sir, on the way. Despite the hurdles that lie in front of me cold, fatigue, the loss of life – my job with the South Carolina Highway Patrol Multi-Disciplinary Accident Investigation Team (MAIT) is to investigate, document, and ultimately prosecute chargeable collisions. To properly reconstruct this collision, three essential and distinct categories must be investigated and documented in order to provide a well-founded explanation of the series of events prior to, during, and after the collision regarding the human, the vehicle, and the environment; this investigative technique is known as the 9-cell collision reconstruction matrix.

The Use of Taglines to Control Crane Loads

Author

The adequacy of a crane’s load line to support the weight of the object being lifted is an obvious concern when evaluating a crane lifting operation. Less obvious, but often equally important, is the presence and adequacy of taglines to provide control of the load orientation.

Taglines are simply ropes or lines that are Read More

Conveyor Backstops: Sometimes One Isn’t Enough, Part 1

This is the first of a two-part blog series describing an incident involving conveying machinery that seriously injured a miner. Part 1 describes the machinery and the incident. In Part 2 I will summarize my engineering analysis of the incident and share the conclusions I reached.

A loaded, inclined conveyor belt may contain hazardous levels of energy due to gravity. To protect workers, anti-reverse devices called backstops are installed on inclined conveyors to prevent unexpected downhill movement. The Conveyor Equipment Manufacturer’s Association (CEMA) defines a backstop as: Read More

Industrial Equipment Failures and Construction Disputes

Author

At Warren, we frequently investigate losses involving industrial machinery.  Many of the losses involve workplace injuries, fires, or explosions; however, we also analyze industrial machinery and processes for other types of problems.  For example, we analyze failures of machinery or industrial processes to perform as expected or disputes that arise from the commercial supply and construction of such systems.  This can encompass a range of issues from failure to achieve required levels of product quality or production quantity, to matters concerning unclear specifications or contracts, Read More

Interpreting Industrial Incident Data – Lesson Learned

This is a case study about an incident I investigated involving a major upset in a distillation column.  This blog builds on the previous blogs about the Distributed Control System, DCS – Data is the Key.

Distillation is a method of separating mixtures of compounds with differing boiling points.  Uncle Bill with his still on the hill separates ethanol, that boils at 173°F, from water that boils at 212°F.  If the mixture is heated to above 173°F, but below 212°F, the ethanol will boil, the vapor will travel up out of the unit and then can be condensed and served over ice with an olive…   Any mixture of two or more chemicals with different boiling points can be separated in this way.  The distillation Read More

WARREN WEBINAR: Property Claims Issues at Manufacturing Facilities

Author

LIVE WEBINAR: “Property Claims Issues at Manufacturing Facilities” | Presented by WARREN’s President and Senior Consulting Engineer, Jennifer Morningstar, P.E., CFEI.

COURSE LEARNING OBJECTIVES
The learning objectives of this course are to provide the attendees with information on the four major facets of property claims that are commonplace in manufacturing facilities.

They are:

  1. Subrogation against third parties;
  2. Boiler & machinery vs property claims;
  3. Scope of loss, and
  4. Business interruption

Each facet will be explored and exemplified by at least one case study.
