Safety Engineer’s Guide to Tool and Instrument Tethering


Injury, damage and lost work hours resulting from untethered tools falling from aloft cost U.S. industry about $6 billion a year. A staggering figure, yet this type of accident is almost completely preventable by using a relatively inexpensive tethering device.   Unfortunately,  until now very little information existed in print to advise safety engineers about safe tool tethering compliance. To help safety professionals choose tethers that increase site safety without impeding productivity, Hammerhead Industries, manufacturer of Gear Keeper tethers and retractable lanyards, has produced the new 12-page  “Safety Engineer’s Guide to Tool and Instrument Tethering.”     

The guide’s “Select the Right Tether in Four Easy Steps” chart is designed as a quick reference that will aid safety professionals when selecting appropriate tethers for tools up to 25 pounds. Also covered in the guide are workplace considerations such as; tethers for working in confined quarters or climbing; tethers that allow for quick interchangeability of tools; when is it mandatory to anchor the tether to a structure instead of a person; choosing tethers that reduce worker’s fatigue and what safety engineers need to know about load-testing and built-in safety margins for tethers.  

The “Industrial Tool  Tether” section includes an X/Y chart that helps safety engineers quickly match tether and lanyard model numbers to tool weight and usage. With over 3,000 tethering configurations available, the guide highlights many of Gear Keeper’s most popular tethers and lanyards. For safety engineers concerned with the safety and protection of hand-held instruments such as bar code readers, the “Instrumentation Tether” section covers a range of tethering options. Among the unique tether configurations described is a shoulder strap tether that offers an exclusive “Instrument Slide” feature that permits instrument movement on the strap without the strap moving on the worker’s body. Even how to tether other workplace objects such as hard hats, security cards, cell phones and micro-tools are covered in the guide. Information is also included about tethering seemingly “untetherable” tools and how to create custom tethers for unique applications.
