“We hardly use that ladder,” the person who calls us almost always says. True: hardly, and nearly always with one hand busy, at night, because there is a stuck valve up top. It is the ladder nobody looks at until the day someone has to climb it in a hurry.
At Indumor we fabricate fixed ladders for building roofs, tanks, silos, platforms and pits: with a cage or with a rail for a ladder safety system, rest platforms and an exit gate, made to measure.
Quote a ladderFirst, whether a fixed ladder is the right answer at all: if someone will climb it every day carrying tools, what you need is a 45° stair. Then, fall protection. Under OSHA 1910.28, fixed ladders that extend more than 24 ft (7.3 m) need it, and on ladders installed since November 19, 2018 it has to be a ladder safety system or personal fall arrest: a cage alone no longer counts, and from November 18, 2036 that applies to every fixed ladder. In Argentina, Decree 351/79 calls for back protection from 2.25 m and rest platforms every 9 m on service ladders. At the top, always, a self-closing gate.
Brackets to the structure run the full height, and outdoors the ladder is hot-dip galvanized.
Once a year: rungs, welds, cage hoops and anchors. And when a section is replaced on a site that follows OSHA, the new section has to carry the ladder safety system.
That is the time to replace fixed ladders or bring them up to standard: it gets done while the plant is down. Request the quote early. Or email tecnica@indumor.com.
