Ladders Are the Most Common Cause of Fatal Construction Falls
OSHA data places ladder falls among the top causes of construction fatalities nationally. In New York, where construction workers routinely use extension ladders, stepladders, fixed ladders, and rolling ladders in every trade from electrical to painting, ladder accidents are a daily reality. About 300 construction workers die from ladder falls annually in the United States; tens of thousands more are seriously injured.
The good news for injured construction workers in New York: ladder falls in construction settings are almost universally covered by Labor Law 240(1). The statute's language explicitly lists "ladders" as required devices. Courts have consistently held that when a worker falls from a ladder that was defective, improperly placed, or failed to provide proper protection, strict liability attaches to the property owner and general contractor.
Understanding exactly what makes a ladder claim viable — and what defenses arise in these cases — helps workers assess their legal situation.
What "Proper Protection" Means for Ladders
Labor Law 240's requirement of "proper protection" applies to ladders just as it does to scaffolds. Courts evaluate ladder protection through several lenses:
Adequate height: The ladder must be tall enough for the task. A six-foot A-frame ladder used to reach a 12-foot ceiling creates an inadequate reach that forces the worker to stand on the top rung or the top cap — positions that are inherently unstable. Courts have found 240 violations in cases where the only available ladder was too short for the task.
Proper placement: Extension ladders must be placed at the correct angle (75 degrees to the horizontal; the "1-in-4 rule" — one foot of base for every four feet of height). A ladder placed at too steep an angle is prone to tipping backward; a ladder placed too flat is prone to sliding out. Improper placement is a 240 violation.
Securing at the top or bottom: An unsecured ladder that slides while a worker is on it violates Labor Law 240. Industrial Code 12 NYCRR 23-1.21(b)(4)(iv) requires that portable ladders be secured at the top or held in place by a second person when the worker cannot secure the top. Failure to secure is a frequently cited 240 violation.
Structural integrity: Rungs that are missing, broken, bent, or weakened; stiles that are cracked; hardware that is corroded or failed — all are structural defects that make a ladder not "proper protection." Defense lawyers sometimes argue that the worker's negligence in using a defective ladder caused the accident. Under Labor Law 240, the question is not whether the worker chose to use the ladder — the question is whether the ladder provided proper protection. If it did not, the owner and GC are strictly liable.
Extension above landing: Industrial Code 12 NYCRR 23-1.21(b)(4)(ii) requires that the top of a ladder used to access an upper level extend at least three feet above the landing — the "three-foot rule." A ladder that does not reach above the upper landing has no stiles for the worker to grasp when stepping on or off, creating a hazardous transition. Failure to extend is a 240 violation.
The Blake Defense: When It Applies and When It Fails
Blake v. Neighborhood Housing Services (1 N.Y.3d 280, 2003) established the "sole proximate cause" defense to Labor Law 240. In Blake, the plaintiff used a ladder that was not secured to the building. The court found that the plaintiff's failure to use a readily available secured ladder, combined with his choice to lean the unsecured ladder in a way that caused it to shift, made him the sole proximate cause of his accident. The property owner escaped liability.
Blake is often cited by defense lawyers in ladder cases as a reason the case should fail. Courts apply it narrowly. The defense requires:
If the ladder that tipped was the only ladder on site, Blake fails. If the available ladder was also defective, Blake fails. If the worker was not instructed to use the secure ladder and did not know it was available, Blake fails. If the worker's use was consistent with normal job site practice (workers routinely use ladders without top securing), Blake fails.
The Cahill v. Triborough Bridge & Tunnel Authority (4 N.Y.3d 35, 2004) refinement: to constitute a recalcitrant worker or sole-proximate-cause defense, there must be a specific instruction to the worker about the safety equipment they should have used, and the worker must have deliberately ignored that instruction. A general site safety rule about ladders, or a general training about proper ladder use, is not sufficient.
Specific Ladder Scenarios and How Courts Treat Them
Extension ladder leaning against wall slides out at base: Classic 240 case. The ladder was not footed (held or clamped at the base) or tied at the top. The failure to secure is the violation. Most courts find liability under 240 in these cases unless Blake applies — which requires a specifically secured ladder to have been available and deliberately ignored.
A-frame stepladder collapses while worker is on it: If the ladder collapsed due to a structural failure — a hinge failure, a broken rung, improper weight rating — this is a 240 case. If the ladder tipped because the worker overreached and shifted the center of gravity, the analysis becomes more complex. Overreaching beyond the ladder's safe working range is the most common defense argument in stepladder cases.
Worker stands on top cap of stepladder because ladder is too short: Courts have held this is a 240 violation — the ladder did not provide proper protection for the task because it was not tall enough. The worker's use of the top cap, while technically improper, was caused by the provision of inadequate equipment.
Rolling ladder without locked casters moves while in use: Industrial Code 12 NYCRR 23-1.21(d) requires that rolling ladders be locked in position while occupied. A rolling ladder that shifts while a worker is on it because the casters were not locked is a 240 violation.
Employer and Foreman Pressure to Work Quickly
One pattern that appears repeatedly in construction ladder cases: workers are under pressure to complete tasks quickly, and taking time to properly set up a ladder — securing it at the top, having someone foot it, selecting the right height — seems like an unnecessary delay. Workers who have been on the job for years develop shortcuts that most days do not result in injury. The day they do result in injury is the day that shortcuts matter legally.
Defense lawyers use this pattern to argue Blake: the worker knew proper procedure and deliberately skipped it. But in most cases this argument fails because: (1) the proper equipment (a secured or more appropriately sized ladder) was not made available, (2) no specific instruction to use a different approach was given for this specific task, or (3) the same shortcuts were universally used on the site without correction, meaning the "deliberate refusal" element is absent.
Frequently Asked Questions
Q: I fell from a ladder at a residential renovation project. The homeowner says they are exempt from Labor Law 240. Is that true?
The one-and-two-family homeowner exemption requires that the owner both own a one-or-two family dwelling AND not direct or control the work. If the homeowner was actively involved in the project — making decisions about what work was done and how, checking in daily, directing contractors — a court may find the exemption does not apply. If the homeowner simply hired a contractor and had no involvement, the exemption may protect them. This is a fact-specific question that requires analysis of the homeowner's actual level of involvement. Do not assume the exemption applies without legal evaluation.
Q: My employer gave me a ladder and I used it. How can the property owner be liable when it was my employer's ladder?
The property owner's non-delegable duty under Labor Law 240 runs regardless of who provided the defective ladder. The owner's obligation is to ensure that proper protection was provided. If the ladder used on their construction project was defective — regardless of who owned it or provided it — the owner remains liable for the failure of that protection. This is what non-delegable means in practice: the owner cannot escape liability by pointing to the subcontractor who brought the defective ladder onto the site.
Q: I fell from a ladder at a job site but the fall was only about six feet. Does the height matter?
No, not in the way people assume. Labor Law 240 does not have a minimum height requirement for falls. A six-foot fall from a ladder that was improperly secured is a 240 case. The statute does not establish a threshold — a fall of any height that is caused by the failure of a required safety device falls within the statute's scope. What matters is the gravity hazard and the failure of protection, not the distance fallen.
Q: The general contractor says I was the only one on that ladder and they had no idea it was being used unsecured. Does their lack of knowledge help them?
No, under Labor Law 240(1). The strict liability standard does not require the owner or GC to have knowledge of the specific hazard. The GC's obligation is to provide proper protection — a secured ladder or a ladder-holder or an adequately stable alternative — regardless of what it actually observed on any given day. Strict liability is incompatible with a knowledge defense; the entire point is that proper protection is required whether or not anyone was paying attention.
Q: I was not told by my foreman to use a ladder — I grabbed one that was on site and used it myself. Does my decision to use the ladder without being directed affect my case?
Courts address this in the sole proximate cause analysis. If you used a ladder that was available on site — even without specific direction to use that particular ladder — you were using the tools available for the work. If the ladder was defective and failed, the question is whether a proper ladder was available and not used. If the only ladder on site was defective, your choice to use it was not a choice to bypass a safer option — no safer option was available. Under those facts, the sole proximate cause defense fails, and your case should proceed.
