  1. WARREN WEBINAR: Property Claims Issues at Manufacturing Facilities

    Leave a Comment

    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.

  2. 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!

  3. 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…)

  4. 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.

  5. 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…)

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

    Leave a Comment

    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. (more…)

  7. The CE Mark and What Should It Mean to You? Part Two

    Leave a Comment

    In the previous blog (Part One) we discussed the backstory behind the two stylized letters CE and what it means to the design of machinery bearing the mark.   We outlined some of the requirements of the “Machinery Directive” (MD) which include what are known as “Essential Health and Safety Requirements.” The Essential Health and Safety Requirements incorporate an iterative risk reduction process during design that takes into account (more…)

  8. Machine Guarding and Risk Assessment

    Leave a Comment

    The Occupational Health and Safety Administration (OSHA) “Top 10 for 2018” violations once again have Machine Safeguarding earning a position on the list. Machine safeguarding was the 9th most cited standard as noted in the list below:

    1. Fall protection, construction (29 CFR 1926.501)
    2. Hazard communication standard, general industry (29 CFR 1910.1200)
    3. Scaffolding, general requirements, construction (29 CFR 1926.451)
    4. Respiratory protection, general industry (29 CFR 1910.134)
    5. Control of hazardous energy (lockout/tagout), general industry (29 CFR 1910.147)
    6. Ladders, construction (29 CFR 1926.1053)]
    7. Powered industrial trucks, general industry (29 CFR 1910.178)
    8. Fall Protection–Training Requirements (29 CFR 1926.503
    9. Machinery and Machine Guarding, general requirements (29 CFR 1910.212)
    10. Eye and Face Protection (29 CFR 1926.102)
