  1. Turkey Fryers- Product Design is Critical to Consumer Safety

    Leave a Comment

    As the holiday season nears, thoughts turn to wonderful home-cooked meals with family.  Few things in life are more pleasurable than a traditional holiday turkey feast. Yet for an unfortunate few, holiday meal time can turn tragic if a turkey frying accident occurs.   While fried turkeys may be tasty, many fire safety experts feel that the reward is not worth the risk.  (more…)

  2. If There is a Human, There are Human Factors

    Leave a Comment

    If there is a human involved in the case, there is a good chance that human factors theories and principles will be applicable. Human factors is the study of people interacting with their surrounding environment. A human factors expert applies their knowledge of human capabilities and limitations to each unique case to assess the physical, sensory, and cognitive factors that caused a person to behave a certain way within the surrounding environment.

    Consider the following situations in which a human factors expert would be beneficial: (more…)

  3. Everybody Has A Part to Play – What’s Your Role?

    Leave a Comment

    Across industry and construction sites, there are times when employees of different employers are working side by side, or at least on the same site at the same time.  Some industry examples are when chemical plants have contractors on-site for routine maintenance or during process shutdowns for major overhauls or repairs. OSHA refers to these as multi-employer worksites.  In December of 1999, they revised their citation policy which allows for more than one employer at a worksite to be cited for conditions that violate OSHA standards.

  5. Heat Exchanger Failures Will Shut Your Process Down

    Leave a Comment

    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!

  6. Residential Structure Fires

    Leave a Comment

    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.

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

    Leave a Comment

    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…)

  8. The Role of Interlocking Guards in Injury Prevention

    Leave a Comment

    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.

  9. The Paths of Chemical Exposure

    Leave a Comment

    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…)
