The ladder rule in general industry is short. Under 29 CFR 1910.23(b)(9), the employer must ensure that "ladders are inspected before initial use in each work shift, and more frequently as necessary, to identify any visible defects that could cause employee injury." The next paragraph says what happens when the inspection finds one: the ladder is tagged "Dangerous: Do Not Use" and removed from service until it is repaired or replaced. This article covers which ladders the rule applies to, what counts as a defect, how the tag-out works, how the construction rule differs, and what a shift check should record.
A note on scope: this summarizes federal OSHA standards for general industry, found in Part 1910, with a short section on the construction standard in Part 1926. States with their own OSHA-approved plans can set different rules, and nothing here is legal advice.
Which ladders the rule covers
Section 1910.23 applies to "all ladders," with two exceptions in paragraph (a): ladders used in emergency operations such as firefighting, rescue and tactical law enforcement, or in training for them, and ladders designed into or forming an integral part of machines or equipment. Everything else is in: portable stepladders and extension ladders, fixed ladders on tanks and buildings, mobile ladder stands and platforms, and stepstools. The inspection duty sits among the "general requirements for all ladders" in paragraph (b), so it applies to every one of those types.
The inspection: before first use in each shift
Paragraph (b)(9) fixes the timing: before initial use in each work shift. A ladder used on three shifts is inspected three times a day. "And more frequently as necessary" adds a second trigger: a ladder that has been dropped, struck or exposed to something that could damage it is looked at again before the next climb.
The object is "any visible defects that could cause employee injury." It is a visual check, not a load test; it is done where the ladder is; and it looks for the defects that matter to safety, which the rest of the section helps define.
The text names no inspector qualification and requires no written record of the shift check. The record is a choice, and the end of this article explains why most sites make it anyway.
What counts as a defect
General industry's ladder standard does not list defects. Its condition requirements do the same job, because a ladder that no longer meets them is defective. Paragraph (b) requires that:
- Rungs, steps and cleats are "parallel, level, and uniformly spaced when the ladder is in position for use," spaced 10 to 14 inches apart between centerlines.
- Rungs, steps and cleats have a clear width of at least 11.5 inches on portable ladders and 16 inches on fixed ladders.
- Wooden ladders "are not coated with any material that may obscure structural defects," so a painted wooden ladder fails on that ground alone.
- Metal ladders "are made with corrosion-resistant material or protected against corrosion."
- Ladder surfaces "are free of puncture and laceration hazards."
- Ladders "are used only for the purposes for which they were designed."
Paragraph (c) adds two conditions for portable ladders: rungs and steps of portable metal ladders are "corrugated, knurled, dimpled, coated with skid-resistant material, or otherwise treated to minimize the possibility of slipping," and each stepladder has "a metal spreader or locking device that securely holds the front and back sections in an open position while the ladder is in use."
The construction standard puts names to the structural defects. 1926.1053(b)(16) lists "broken or missing rungs, cleats, or steps, broken or split rails, corroded components, or other faulty or defective components." It is a fair description of what the general industry inspector is looking for, too.
When the inspection finds a defect
Paragraph (b)(10) leaves no room for a ladder to stay in use while a repair is arranged: "Any ladder with structural or other defects is immediately tagged 'Dangerous: Do Not Use' or with similar language in accordance with § 1910.145 and removed from service until repaired in accordance with § 1910.22(d), or replaced." Two other standards are pulled in by that sentence.
The tag, 1910.145(f). OSHA's rule on accident prevention tags requires a signal word and a major message. Danger tags are reserved for "major hazard situations where an immediate hazard presents a threat of death or serious injury," which is why the ladder rule asks for "Dangerous"; the major message, such as "Do Not Use," names the instruction. The signal word must be readable from at least five feet, the tag is attached "as close as safely possible" to the hazard "by a positive means such as string, wire, or adhesive that prevents their loss or unintentional removal," and it stays on until the hazard is eliminated.
The repair, 1910.22(d). The walking-working surfaces rule requires hazardous conditions to be corrected or repaired before an employee uses the surface again, or guarded until they are, and when a repair "involves the structural integrity" of the surface, a qualified person performs or supervises it. A cracked rail or a bent rung is structural; a missing foot pad may not be, but the ladder still comes out of service.
The alternative is replacement, which for many portable ladders is the realistic outcome.
Set-up and use rules the inspector should know
The person doing the shift check is usually the person about to climb, and paragraph (c) sets the conditions of use for portable ladders:
- Not loaded beyond the maximum intended load, which the standard's note defines as the total of the employee and all tools, equipment and materials carried.
- Used only on stable and level surfaces unless secured or stabilized; on slippery surfaces, secured and stabilized.
- In passageways, doorways or driveways, secured or guarded by a temporary barricade such as cones or caution tape.
- The cap and the top step of a stepladder are not used as steps.
- Both side rails supported at the top, and a ladder used to reach an upper landing extends at least three feet above it.
- Not moved, shifted or extended while occupied; not tied together for added length unless designed for it; not set on boxes, barrels or other unstable bases; and no single-rail portable ladders at all.
For climbing, paragraph (b) requires each employee to face the ladder, keep at least one hand on it, and carry nothing "that could cause the employee to lose balance and fall."
Fixed ladders and mobile ladder stands have their own design rules in paragraphs (d) and (e), and the standard's note points to 1910.28 for fall protection on fixed ladders.
How the construction rule differs
Construction sites follow 1926.1053. Its inspection rule, paragraph (b)(15), reads: ladders "shall be inspected by a competent person for visible defects on a periodic basis and after any occurrence that could affect their safe use." It names an inspector and does not tie the check to each shift. The remedy is similar: a defective portable ladder is marked as defective or tagged "Do Not Use" and withdrawn until repaired, and a defective fixed ladder may instead be blocked, for example with a plywood panel across several rungs. A contractor's crew in a plant brings its own standard with it; the plant's employees are under 1910.23.
What a shift ladder check should record
Our ladder inspection checklist, free as a PDF, Excel or Word file, follows paragraphs (b)(9) and (b)(10) and the condition rules above.
Ladder:
- The ladder's tag is scanned, so the record belongs to that ladder.
- The type: stepladder, extension, straight or platform.
- Labels and the duty rating legible, since the maximum intended load is read from the label.
Condition:
- Side rails straight, with no cracks, splits or bends.
- Rungs or steps secure, not bent or missing, and free of oil, grease and mud.
- Feet and slip-resistant pads in place.
- Spreaders or rung locks work and lock fully.
- Rivets, bolts and hardware tight.
- On extension ladders, the rope and pulley not frayed or worn.
Result:
- Safe to use, or tagged "Do Not Use" and removed, with a photo of any defect and the inspector's name and time.
Fixed ladders and mobile ladder stands need their own versions, with the clearance, rail extension, caster and handrail items from paragraphs (d) and (e).
Making it real
The standard requires no record, but the tag-out in (b)(10) starts a repair or a replacement that someone has to own, the ladder that keeps failing is the one to retire, and a check done by the person at risk minutes before the risk is worth thirty seconds of evidence.
- Scan the ladder, not the sheet. A QR code or NFC tag on each ladder, scanned as the check starts, ties the record to the ladder; see how a code on the equipment opens its asset record.
- Make the check the record. A form on a phone with the condition items above, a photo of any defect and a name and time is the whole record, done at the ladder.
- Make the tag-out an outcome. When the result is "tagged and removed," the ladder's status changes, the repair or replacement becomes a work order with an owner, and the ladder stays out of service in the system until the work is closed. Why findings stall between the check and the fix is covered in why inspection findings stall before they become work orders.
The same approach applies to the other daily and weekly safety checks, from walking-working surfaces to fire extinguishers; see safety inspections that get done.
Quick summary
- 1910.23(b)(9): every ladder is inspected before first use in each work shift, and more often as necessary, for visible defects that could cause injury.
- 1910.23(b)(10): a defective ladder is immediately tagged "Dangerous: Do Not Use" or similar under 1910.145 and removed from service until repaired under 1910.22(d) or replaced.
- The condition rules define the defects: rung spacing and width, no coatings that hide defects, corrosion protection, no puncture or laceration hazards, slip-resistant rungs, a working spreader on every stepladder.
- Construction follows 1926.1053: a competent person inspects periodically and after any occurrence.
- No record is required; the tag-out and the repair it starts are why one is worth keeping.
