Did you know that a wire rope lanyard designed for fall arrest is not the same
as a wire rope sling that is designed for lifting?
When used as a fall arrest lanyard, wire rope by itself is unable to absorb any type of energy. Because there is no elasticity or stretch, this will subject a worker to a injury or even a potential amount of fatal arrest-force should they happen to fall while wearing it.
When wire rope is used as a connecting device, it is absolutely essential that a Personal Energy Absorber is used along with it. A PEA should actually be used with any lanyard or connecting device that allows for potential free fall, despite the fact that the webbing or rope of some lanyard types does actually absorb small amounts of energy.
Most jurisdictions, including Saskatchewan, prohibit fall
forces in excess of 8 kilonewtons. Therefore, employers are
legally required to ensure that a personal fall arrest system used by their
employees is set up in order to prevent arrest forces in excess of 1800 pounds.
The amount of force a human body can withstand has not
technically been verified by modern science. Less arrest force is generally easier on a person's body than more fall force. Additional information on this topic can be found here.
Wire rope slings should never be used as connecting devices in a Personal Fall Arrest System; it
will subject a falling worker to more fall force than a proper energy-absorbing lanyard would.
Northern Strands provides training on both the proper use of fall
arrest equipment and the proper use of rigging equipment. If you
would like more information one either of these programs, please contact us.

Over the last few decades worker safety in Canada has become an area of utmost importance for our government, companies and workers. Worker fall protection safety has been a particular area of focus in safety regulations and culture across Saskatchewan and Canada.
Did you know that Saskatchewan's Occupational Health and Safety Regulations states that, "An employer or contractor shall develop a written fall protection plan where:
(a) a worker may fall three metres or more; and
(b) workers are not protected by a guardrail or similar barrier."?
What constitutes a fall protection plan or system? OH&S regulations state, "The fall protection plan required by subsection (1) must describe:
(a) the fall hazards at the worksite;
(b) the fall protection system to be used at the worksite;
(c) the procedures used to assemble, maintain, inspect, use and disassemble the fall protection system; and
(d) the rescue procedures to be used if a worker falls, is suspended by a personal fall arrest system or safety net and needs to be rescued.
(3) The employer or contractor shall ensure that a copy of the fall protection plan is readily available before work begins at a worksite where a risk of falling exists.
(4) The employer or contractor shall ensure that a worker is trained in the fall protection plan and the safe use of the fall protection system before allowing the worker to work in an area where a fall protection system must be used."
Northern Strands Engineered Fall Protection Division recently completed a job where we installed an Engineered Fall Protection System for a commercial rooftop. We completed the installation of two force management anchors on a standing seam roof. Standing seam clamps are attached to the roof top. Bearer bars bridge the gap between two standing seams. Anchor plates are the riveted to the bearer bars and the pull tested. Finally the anchors are assembled on the anchor plate and torqued. These rooftop anchors are now ready for the customers use.
If you have questions regarding commercial rooftop fall protection plans, please contact the Engineered Fall Protection Division of Northern Strands at 306.242.7073, email firstname.lastname@example.org or visit our webpage http://www.northernstrands.com/fall-protection.aspx
