Answer: This is a very good question. We had to turn to our Heil Trailer International, Co. Canadian distributor (Intrans-Corp, Ph: 218-829-6136, Cell: 320-412-6521, email@example.com) to get an answer. To the best of our knowledge, there is no specific fall protection requirements. There are however, some general safety requirements such as “no platform can be any higher than the overturn protection”, but these are basic government safety regulations that trailer manufacturers have been required to follow for a very long time and just about any trailer will have this incorporated or just will not have any type of catwalk/walkway. What we have found is that most companies, both trucking and shipping, have their own requirements as to what their fall protection policy is going to be in accordance to their safety department and insurance company requirements. This means if you are moving product for Ecana or Shell your trailer has to meet their safety regulations, which would include fall protection. Our suggestion is that you discuss with your company and the company you are hauling product for and ask them what are their current safety / fall protection requirements.
