In the old-timey Fire Triangle, you have heat, fuel, and oxygen. Get these three together in the right quantities, and you get fire. What if the fuel provides its own heat? That’s spontaneous combustion, or spontaneous ignition. NFPA921 defines this as “initiation of combustion of a material by an internal chemical or biological reaction that has produced sufficient heat to ignite the material.” (more…)
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, (more…)
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:
Each facet will be explored and exemplified by at least one case study.
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!
The winter season is well underway in the United States, with the Christmas and New Years holidays behind us and the depths of cold weather here for the duration. With winter, many people spend more hours indoors as compared to the summer when outdoor activities ramp up. With more time spent indoors, it is somewhat intuitive that the use of electricity would increase as well.
Electricity is one of the most influential utilities in our daily life. Much of what modern societies rely on to get through a normal day requires electricity. Have you ever been in a slight panic looking for an electric outlet when your cell phone is below 10% charge? Or how many times do we all attempt to turn on a light switch when we enter a room during a known power outage from sheer habit? Even our personal transportation which has relied on gasoline for roughly 100 years is shifting toward electric automobiles. (more…)
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. (more…)
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 (more…)
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. (more…)
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. (more…)
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.
