WARREN WEBINAR: Property Claims Issues at Manufacturing Facilities

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.

Heat Exchanger Failures Will Shut Your Process Down

Author

Heat exchangers, as the name implies, are used to bring a process stream to a desired temperature.  They can heat or cool either gases or liquids. They are fairly intricate in their construction, therefore not the cheapest piece of equipment to purchase.  For that reason, facilities don’t keep “spare” exchangers lying around, so when they fail catastrophically, the entire manufacturing process goes down with them… and stays down until they are fixed or replaced. Ow!

Heating System Losses, Part One

Author

When fall and winter arrive and temperatures drop, it is a great comfort to have a heating system to warm your home or office. Several categories of heating equipment exist to provide both primary and secondary heating. Primary heating systems include fuel gas/fuel oil/electric forced air furnaces, heat pumps, hydronic heating/steam systems and even wood-fired heating systems.  Secondary heating equipment includes electric, gas and kerosene space heaters of both fixed and portable design, and fireplaces. Each of the different types of heating systems have unique hazards that, uncontrolled, can result in fires, explosions, burn injuries, and carbon monoxide poisoning.  Read More

P&ID’s, If You Please – Piping and Instrumentation Diagrams Explained

Author

When investigating an industrial incident, one piece of information I always ask for is the relevant P&ID’s for the process.  P&ID stands for Piping and Instrumentation Diagram and is defined as “A schematic diagram of the relationship between instruments, controllers, piping, and system equipment.” A set of P&ID’s for an entire facility allows you to trace the entire manufacturing process from raw material unloading to finished product loadout, including utilities like steam, water, fuel, and air. That’s great information to have, but isn’t especially useful Read More

The Role of Interlocking Guards in Injury Prevention

Author

In the three-part series on the CE mark, we scratched the surface of some of the requirements an equipment manufacturer must meet in order to earn this designation. Part three of the series dealt with some of the requirements for the design of a guard.  One of the items for consideration with the design of a guard is the frequency that someone will need to access the area protected by the guard.  If access is needed on a routine basis, often defined as more than once per shift, the guard needs to be designed to be movable instead of fixed.  Movable is defined as able to be opened without the use of tools.  Otherwise the frustration and time requirements of obtaining tools and removing a fixed guard will often lead to the guard being discarded.

The Paths of Chemical Exposure

Author

The Safety Hierarchy states that hazards should be mitigated first by engineering controls, secondly by guarding, and lastly by warning/training.  When the first two, engineering controls and guards, fail in a manufacturing setting, a chemical release could occur. A forensic chemical engineer can help determine the root cause of that failure. Read More

Don’t Get Burned With Your Gas Grill!

Author

If there is one thing Americans can agree upon, it is the enjoyment that comes from an outdoor barbeque.  Whether a summertime cookout or a fall BBQ to watch a football game, we all love the fun and fellowship that comes from sharing a meal that was prepared outdoors on a grill or smoker.  In fact, 64% of Americans own a grill or smoker.  The great majority of these are LP fueled gas grills with comparatively few natural gas fired grills.  These products can be enjoyed safely when designed, installed, and used in a proper manner.  However, given the grill’s use of flammable fuel gas and high temperatures, the potential exists for things to go wrong and result in burn injuries or uncontained fires that spread to the surroundings.

What You May Not Know About Using a Concrete Test Hammer

Author

When assessing potential problems in concrete structures, consider a non-destructive test using the concrete test hammer, AKA “rebound hammer,” before investing a lot of time and money needlessly replacing or destructively testing the concrete structure.  The use of rebound hammer tests should be considered before you or your client decide to drill multiple core samples. Large areas of the concrete structure suspected of having potential strength problems can be tested quickly with a rebound hammer.  Analysis of those results can narrow down specific areas for more rigorous testing.

The Demise of Insulation on Electrical Wiring

Author

Unlike fine wines and some types of cheeses, not everything ages well.  Such is the case with the materials used as insulation of electrical wiring.  While the copper metal used as the conductor in many wire types will last virtually forever, the cladding used to protect and insulate the wire allowing electrons to flow to their final destination does not.

What’s Behind That CE Mark Part Three, Machine Guard Requirements

Author

In the first blog in this series, we discussed the story behind the CE mark, the Machinery Directive, and the associated requirements regarding the design, production, and sale of machinery bearing the mark. The second blog discussed a cornerstone of safer machine design, the risk assessment. This installment will discuss another crucial piece of the safety puzzle, machine guard design. Read More
