ANSI A1264.1 Updated – Workplace Safety

Brad Kelechava 2 Comments As we have previously discussed , falls can be tragic, as they account for 15 percent of all accidental deaths in industry and cause other secondary accidents. So, while the average person may not anticipate a simple fall to be the instigator of their own doom, it is essential that the necessary steps be taken to prevent falls from occurring. However, it would be presumptuous to assume that any single person can be alert and prepared for every potential fall hazard. The solution for this problem is to have those in charge of walkable surfaces manage them so as to limit any types of falls. For industrial and workplace situations, this involves identifying and handling obstructions and other hazards. It is important to note that the scope of this document applies to more than industrial settings, and it is intended for different workplace settings used and occupied mainly by workers. The revision has several technical improvements over the previous version of the standard, as well as two new definitions and four new illustrations to help clarify text.
