A new legislation will soon require Alberta farmers to ensure their farms are equipped with proper safety plans. Emergency response, fall protection, and hazard assessments are just some of the plans that will be implemented to ensure worker safety on Alberta farms. The Alberta agriculture sector will now begin using checklists to help maintain these safety programs.

One of the largest concerns for Alberta farm and worker safety is grain bin fall protection. Alberta farmers can use the Northern Strands Grain Bin Fall Protection system to protect workers from a fall while climbing or accessing a grain bin for repairs. The user simply attaches a harness to a traveller and moves the traveller up as they climb the bin. The Grain Bin Fall Protection System meets OH&S farming requirements, is easy to use, and is cost effective all while protecting farmers, workers, or family members from a devastating fall.

Based out of Saskatoon Saskatchewan, Northern Strands provides services to Canadian farmers and mines all across the country. With safety as an integral part of operations, Northern Strands has grown over the years in order to develop this patented Grain Bin Fall Protection System.

The Term MAF, also known as Maximum Arrest Force, comes directly from Section 102 of The Occupational Health and Safety Regulations, 1996 under clause (c) which states that "An employer or contractor shall ensure that a personal fall arrest system required by these regulations...applies a peak fall-arrest force not greater than eight kilo-newtons to a worker..."

A kilo-newton is a force that is equal to approximately 225 lbs-force. Where the Saskatchewan fall-arrest legislation states Max Arrest Force is 8kN, this is equal to 1800 lbs-force. So how do we abide by this legislation and what does it mean?

In the Northern Strands Fall Protection course, they train that Personal Fall Arrest Systems should be a last resort, but S102(c) was put in place to make sure that the risk of injury from the fall-arrest equipment itself is reduced.

Recently Northern Strands launched it's Grain Bin Fall Protection System at AG in Motion, the fastest growing Agriculture trade show in Canada. The response was overwhelmingly positive! Farmers from across Canada stopped by our booth to express interest in our Grain Bin Fall Protection System. Farmers were very excited at the prospect of a simple, easy to use, cost effective solution that would prevent people from falling off a grain bin and impacting the ground or falling to the bottom of a grain bin and suffocating. At Northern Strands we believe serious injuries are preventable and avoidable with proper planning and systems in place. It is with this belief in mind that Northern Strands accepted the challenge of making grain bin inspections and repairs more safe by developing a fall protection system. Our patent pending fall protection system is a cutting edge product designed to protect farm workers from a fall while climbing or accessing a bin for repairs or inspections. 

Almost every farmer had a story to tell of them or someone they know falling off or in a grain bin. We obviously knew people fall off grain bins, but we were shocked at the high frequency in which grain bin falls happen. Many farmers we talked to had a story to tell, from broken legs, arms, backs, you name it we heard it.

One very exciting aspect of the trade show was our fall protection system being nomination for the AG in Motion Innovative product award. This nomination brought us to the attention of numerous media outlets. By the end of the trade show our fall protection team had completed at least a half dozen interviews on the Grain Bin Fall Protection System.

This fall protection system is a cutting edge product designed to protect farm workers from a fall while climbing or accessing a bin for repairs or inspections. In today’s world, worker/farmer safety has never been more emphasized and important than it is right now. At Northern Strands we believe serious injuries are preventable and avoidable with proper planning and systems in place. It is with this belief in mind that Northern Strands accepted the challenge of making grain bin inspections and repairs more safe by developing a fall protection system. When properly installed and used, our system will prevent a person from falling off a grain bin and impacting the ground or falling into the bottom of a grain bin and suffocating. Currently this system is compatible with the Westor and Westeel 1805 bins. Northern Strands is working on Fall Protection Systems that will work for other models of grain bins.

The launch for this new Grain Bin System is happening at AG in Motion Tuesday July 18, 2017 - Thursday July 20, 2017. AG in Motion is just 15 mins NW of Saskatoon on Hwy 16 at Range Road 3083. Northern Strands will be at Booth Space 420. There will be demos throughout the week.

Did you know that violations of fall protection regulations can result in personnel and company fines in the range of thousands of dollars? Or that injuries or deaths resulting from fall protection violations can result in legal action and cost companies tens of thousands of dollars? Recently one such story was published by CBC Saskatchewan http://www.cbc.ca/news/canada/saskatchewan/safety-violation-saskatchewan-employer-occupational-health-1.4030827 Thankfully, more companies than not are now taking fall protection very seriously in Saskatchewan, and Northern Strands is here to help!

Our Northern Strands Fall Protection Division is often asked, "What are the OH&S regulations regarding fall arrest personnel protective equipment and general fall protection in Saskatchewan?" Or the similar question, "What are the roof fall protection requirements in Saskatchewan?" For the convenience of our customers and clients we have posted the Occupational Health and Safety Regulations relating to fall arrest personnel protective equipment and fall protection in the second half of this blog...

Additional fall protection questions Northern Strands Fall Protection is regularly asked, "What are my responsibilities as an employer? What kind of fall protection plan do I need and how to I implement it?" These are all very good questions that we are more than happy to answer. However the answers can potentially vary depending on the situation. In most cases our Fall Protection Team will need to visit the site to perform an assessment and provide a recommendation or quote. 

Contact the Northern Strands Fall Protection Division today to find out more about OH&S fall protection regulations in Saskatchewan by requesting an assessment. We specialize in the design and installation of roof fall protection systems.
