  2. Safety Distance in Machine Safeguarding

    Leave a Comment

    Hazard can be defined as a potential source of harm.  Machine safeguarding seeks to protect people from these potential sources of harm.  Often distance from a hazard will play a key role in providing a means of protection.

    One would often think of distance as it relates to the location of a barrier guard from a hazard.  ANSI B11.19, Performance Criteria for Safeguarding, defines safety distance as “the distance a safeguard is installed from a hazard such that individuals are not exposed to a hazard.”  An example from ANSI B11.19 of the recommended distance of a slotted opening in a barrier guard from a hazard is shown (more…)

  3. Danger Within Reach

    How far away from a hazard should you stay?  Your parents or grandparents would probably have told you to stay far away, but what are you to do when a hazard is present, and you must work around or near the hazard?  And what exactly is a hazard?  ISO 12100 Safety of machinery – General principles for design – Risk assessment and risk reduction defines a hazard as a “potential source of harm.”

    Where would a designer of a machine or product start if they wished to protect the user from a known hazard?  Consensus standards are a great place to begin the quest for safety. (more…)

  4. HEY…Cover Up Please!

    Leave a Comment

    Machine guards can be compared to the clothes we wear every day.  Indeed, they serve a very important purpose.  Imagine someone leaving their home on a fine, sunny morning wearing nothing but a smile.  Wonder how far they will get through the day before things start going poorly for this individual?

     

     

     

     

     

    There will be more than a few raised eyebrows and blushes when he stops into the local Starbucks for his usual morning double-dipped and whipped, chocolaty chip with a touch of pumpkin spice cappuccino fix.  Good luck with that!  Probably going to leave disappointed, empty-handed, and likely wearing handcuffs.  This will be the beginning of a very long, very bad day for that individual.  Had he recognized the risks associated with this type of behavior, and then put forth a little effort to cover up, he would have prevented many unfavorable and possibly life-changing personal and legal problems from ever occurring!

    And so it is with properly guarding a machine.  Machine safeguarding helps to protect workers from preventable injuries. (more…)

  6. The Concepts of Hazard, Risk, and Harm in Machine Safeguarding

    Leave a Comment

    Hazard, risk, and harm are terms that are used in the world of machine safeguarding.   How do these words shape the concept of machine safeguarding? Let’s look a little deeper….

    Hazard, which Merriam-Webster defines as a noun, lists its first meaning as a source of danger.

    1: a source of danger

    2a: the effect of unpredictable and unanalyzable forces in determining events : CHANCE, RISK

      b:  a chance event : ACCIDENT  (more…)

  10. Fire Investigation Points to Design Failure.

    Leave a Comment

    Defects that cause problems in machines are categorized into two different concepts. Manufacturing defect is a term that applies to a situation where the defect was unintended. For example, a part was installed that did not meet the designer’s specifications or quality. A design defect is another matter. Design defect is a term that applies to a situation where the defect resulted from a purposeful decision or by failing to investigate or heed available design criteria on the part of a designer or builder.
