Accidents involving ladders can result in serious injury, even death. It often happens for a simple reason – the user does not think about how to use them correctly and safely and does not follow the rules for working at heights. However, the statistics adamantly state the facts about getting more and more work-related injuries.
It is not allowed to use ladders, knocked down by nails, without fastening the bowstrings with bolts and cutting steps into the bowstrings. At least two metal tie bolts are installed under the steps for attached wooden ladders and stepladders more than 3 m long.
The width of the ladder and stepladder at the top must be at least 300 mm, at the bottom – at least 400 mm. In addition, the distance between the steps of the stairs should be from 0.30 to 0.35 m, and the distance from the first step to the installation level (floor, ceiling, etc.) should not be more than 0.40 m.
Vertical ladders with an angle of inclination to the horizon of more than 75 degrees at more than 5 m, starting from a height of 3 m, must have been fenced in the form of arcs. Arcs should be located at a distance of no more than 0.8 m from one another and connected by at least three longitudinal stripes. The distance between your ladders up to the arch needs to be at the minimum of 0.7 millimeters and no greater than 0.8 meters, with an arc’s diameter of 0.35 to 0.4 meters.
Taller extension Ladders that exceed 10 meters should be fitted with rest areas at least 10m high. Stepladders are equipped with tools (hooks chains, hooks) that do not allow them to break apart when working on them in a synchronized manner. The ladder’s slope should not exceed 1:3.
For the passage of workers performing work on the roof of buildings with a slope of more than 20 degrees and a roof with a coating that is not designed for the weight of workers, ladders are arranged with transverse slats to support the legs. The ladders are fixed at the time of work.
Extension Ladders and bridges must be rigid and have fastenings that exclude the possibility of their displacement. If the length of ladders and bridges is more than 3 m, intermediate supports are installed under them.
