  1. You’re Just Not My Type – Part 1: Guards

    Leave a Comment

    Selecting the best or most effective way to reduce or eliminate risk from a particular machine hazard is an extremely important process.  It can mean the difference between someone going home and hugging their wife and children…to never going home again.  The hazard control hierarchy (see figure below) is an available tool that illustrates what is known to be most effective to least effective when it comes to eliminating machine hazards or reducing the risk from those hazards to an acceptable level.  Removing the hazard by designing it out is by far most effective.  (more…)

  2. CHECK OUT THAT RACK! – The Importance of Inspecting Storage Racks for Proper Installation

    Leave a Comment

    People have too much “stuff”. Manufacturers, retailers, wholesalers, and commercial enterprises all carry inventory of “stuff”, too. According to the Energy Information Administration’s (EIA’s) own statistics, in 2018, the US had over 17.4 billion ft2 of warehouse and storage. Growing from just 13 billion ft2 in 2012, warehouse and storage space is the fastest growing and now the largest use of commercial space in the US, overtaking office space for the first time in modern history.

     

    Almost every one of those buildings contains storage racks. And this doesn’t include the mercantile spaces. You can go to a big box retailer and buy cereal from a lower shelf while pallets of grain or packaged drinks sit 20-30 feet above, waiting to be introduced to the customer.

    There is no specific OSHA regulation for anchoring storage racks – (more…)

  3. Stop or I’ll Soot!!!

    Fire. Something about fire touches our brainstems…both good and bad!  Uncontrolled fire is terrifying and deadly to be sure.  But the controlled burning of wood at a campfire or in a fireplace in your home almost can’t be beat, to my mind! For that very reason, a fairly common amenity to houses nowadays is the gas log fireplace insert.

    When not installed properly, these logs will generate soot. These soot particles can leave the fireplace and meander.  All. Over. Your. House.  (more…)

  4. KEEP the CHANGE?

    Leave a Comment

    As we all know, change is a part of life.  Sometimes the results from change are good.  And we know sometimes change may result in things becoming worse, although it may not be immediately evident.  I think it is safe to say that when we intentionally make changes to something, our goal is to make it better with respect to one or more metrics.  Engineers working in manufacturing facilities are often asked to make changes to existing machines and processes for multiple reasons: (more…)

  5. Spontaneous Combustion…Is it hot in here or is it just me???

    Leave a Comment

    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…)

  6. Water Removal In Windows and Doors – Part 3: Sill Risers

    Leave a Comment

    Welcome back to my multi-part series about water resistance in windows and doors. Last time we discussed weatherstripping. Today, we move on to a product common to sliding doors and coastal areas – sill risers.

    Sill risers offer a brute force way to reduce water infiltration when a LOT of water is expected to hit a fenestration product. Unlike weathersealing, buried drainage, or weep systems, sill risers block water by providing a dam. Coastal homes with wind driven rain frequently have sill risers. They are practical and require less maintenance than weep holes or buried drainage systems, plus (more…)

  7. Machine Guarding Resources

    Leave a Comment

    So, you find yourself with a machine hazard that you need to guard.  Where do your turn for guidance regarding guards?  Several resources are available for the person who is tasked with providing machine guarding.

    The United States government provides resources in the Code of Federal Regulations (CFR).  These can be found at www.ecfr.gov.  Title 29 of the CFR, section 1910 covers “General Industry” regulations.  1910 Subpart O, covers Machinery and Machine Guarding.  Definitions are covered in 1910.211 and it is wise to understand how terms are defined. For instance, in 1910.211(a)(1), Point of operations is defined by the regulation as “that point at which cutting, shaping, boring, or forming is accomplished on the stock.” (more…)

  8. Water Removal In Windows and Doors – Part 2: Weatherstripping

    Leave a Comment

    Welcome back to my multi-part series about water resistance in windows and doors. Last time we discussed weep holes. Today, I’d like to talk about weatherstripping (also known as weathersealing).

    During the life of typical exterior fenestration products, every driven rain is a test of the product’s water weathersealing system. Most windows and doors handle water without much homeowner input, but racked or misaligned windows, poor weatherstripping corner joints, and torn piles all contribute to reduced water infiltration resistance. They can allow moisture into the structure, where damage to flooring, walls, and (more…)

  9. Don’t Get Burned With Your Gas Grill!

    Leave a Comment

    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.

  10. Water Removal In Windows and Doors – Part 1: Weep Holes

    Leave a Comment

    In architecture, the word fenestration is used to encompass the windows and doors in a building. During my twelve-year career as a design engineer in the fenestration industry, water infiltration resistance (I.E., stopping leaks) consumed almost as much time in the test lab as pressure or impact testing. During the life of typical exterior fenestration products, every driven rain is a test of the product’s water evacuation system. Most windows and doors handle water without much homeowner input, but poor, clogged or covered water drainage systems can allow moisture into the structure, where damage to flooring, walls, and molding may occur. Poor water infiltration resistance also increases the humidity in a living space. (more…)
