The DOs & DON’Ts of Tool Tethering

Did you know that dropped objects rank in the top 3 of the deadliest workplace accidents in the UK, according to the latest statistics from HSE’s Riddor Report 2017/18? Falling objects also accounted for over 7,000 reported non-fatal injuries, with 75% of them resulting in over 7 days of lost work time each (2016/17).

Here at Tool@rrest we’re working hard to make the best tool tethering technology widely available and put a stop to the fatalities, injuries, site damage and project downtime caused by dropped tools.

In today’s blog, we’re taking a look at what you need to do (and not do!) to ensure optimum safety and efficiency when using tool tethering systems.

Tool Tethers

DO’s

• ALWAYS use a Certified and Rated Tether that is
  suitable for the weight of the Tool.
• ALWAYS ensure the tether is fitted by a
  competent professional.
• ALWAYS Verify the integrity of a tether prior to
  use looking for indications of excessive wear and tear or fatigue. (If in
  question, replace the tether).

DON’Ts

• DON’T use a homemade tether.
• DON’T use a tether that has not been fitted by a
  competent professional.
• DON’T use a tether that is not certified and
  tested for the tool weight.
• DON’T tether a tool that exceeds 2.5 kg to a
  person.
• DON’T use a tether exhibiting deformities,
  unusual wear or deterioration. This must be immediately discarded and replaced
  before using the tool.

Lanyards

DOs

• ALWAYS use a lanyard that is tested and rated
  for the tool weight.
• ALWAYS inspect your lanyard prior to use looking
  for indications of excessive wear, failed stitching and ensure Karabiners are
  in good clean working order. (If in question, replace the lanyard.)
• ALWAYS weigh tools so that a properly rated
  lanyard is used for the application (never assume the weight of a tool just by
  feel).
• ALWAYS ensure the lanyard at full extension drop
  will not impact with workers below you.
• ALWAYS verify the tool’s attachment point to
  ensure that it is strong enough to hold the tool for the full drop distance of
  the lanyard.
• ALWAYS anchor all tools weighing more than 2.5
  kg to a secure, fixed and rated anchor point, never to a person.
• ALWAYS use a quick-change lanyard when a group
  of small tools are being used.
• ALWAYS use a retractable lanyard where there is
  risk entanglement or snagging and multiple tools are being used.
• ALWAYS use lanyards that have very low stretch
  force at full extension so long as they have the correct degree of recoil for
  the tool and application.
• ALWAYS transfer shock loads from a person to a
  rated structure whenever possible.
• ALWAYS ensure the weight of the tools attached
  to the body does not overload and exceed the weight limit of the harness.

DON’Ts

• DON’T ever use a tool lanyard with lower weight
  limits than the tool being tethered.
• DON’T tether a tool to a person without
  verifying the impact on the persons “Personal Fall Protection” (PFP) devices.
• DON’T attach a lanyard to a structure without
  verifying the strength and shock-load capability of the anchor point.
• DON’T use lanyards that require excessive force
  for full extension. (This will cause increase muscle fatigue.)
• DON’T modify the tool lanyard in anyway
  (replacement of tool lanyard components such as Karabiners, clips will change
  the load rating).
• DON’T connect more than one Tool Lanyard
  together.
• DON’T customize the tool lanyard with hardware
  that does not have the appropriate load ratings for the tool.
• DON’T assume that a tool tether is a fool proof
  device.
• DON’T use a tool lanyard as a Personal Fall
  Protection (PFP) lanyard.
• DON’T use tool lanyards to the body in
  situations where machinery entanglement is a concern, most tool tethers will
  not breakaway against the weight of a person.

Remember, if in doubt, always check with a qualified safety professional before proceeding.  If you’d like to discuss your tool tethering requirements, please get in touch with the Tool@rrest team or call:  +44 (0) 1952 292 782.
