DO verify the integrity of a tether prior to use looking for indications of excessive wear or
fatigue. (If in question, replace the tether.)
DO always use a lanyard that is rated properly for the tool weight providing that the lanyard is
designed with a 25% or more additional margin for a full extension drop.
DO verify the tool's attachment point to ensure that it is strong enough to hold the tool for the
full drop distance of the tether.
DO weigh tools so that a properly rated lanyard is used for the application (never assume the
weight of a tool just by feel).
DO use a quick release tether when a group of small tools are being used.
DO use a retractable tether to avoid entanglement issues when multiple tethers are needed.
DO anchor all tools weighing more than 10-lb to a structure, not a person.
DO use lanyards that have very low stretch force at full extension so long as they have the
proper degree of recoil for the tool and application.
DO transfer shock loads from a person to a structure whenever possible.
DO always check with a qualified safety professional if in doubt.
DON'T ever use a tether with lower weight limits than the tool being tethered.
DON'T tether a tool that exceeds 10-lbs to a person.
DON'T tether a tool to a person without verifying the impact on the persons "Personal Fall
Protection" (PFP) devices.
DON'T attach a tool tether to a structure without verifying the strength and shock-load capability
of the anchor point.
DON'T use tethers or lanyards that require excessive force for full extension. (The result will be
reduced worker output and possible muscle injury.)
DON'T modify the tool lanyard in anyway (replacement of tool lanyard components such as
carabiner clips, side release disconnect clips or removal of shock absorbing components may
impact the load-rating of the lanyard).
DON'T customize the tool lanyard with hardware that does not have the appropriate load ratings
for the tool. (i.e. Key rings are often considered for use as an attachment point to a tool, but
typically these will not work for tools weighing more than 1-lb).
DON'T assume that a tool tether is a foolproof device.
DON'T use a tool lanyard as a PFP lanyard.
DON'T use tool tethers in situations where machinery entanglement is a concern, most tool
tethers will not breakaway against the weight of a person.
