NYCRR § 23-1.12: Guarding of Power-Driven Machinery on New York Construction Sites

NYCRR § 23-1.12 is a New York Industrial Code regulation requiring physical guards on seven categories of power-driven machinery at construction, demolition, and excavation sites. Those categories include rotating projections, power saws, sprockets and gears, belts and pulleys, friction-disc drives, and wire rope nip points. When a violation hurts a worker, it can support a claim under New York Labor Law § 241(6).

If you work near machinery on a New York job site, this is one of the safety rules meant to protect you. The full name is 12 NYCRR § 23-1.12. It sits inside the New York Industrial Code (12 NYCRR Part 23). That code governs construction, demolition, and excavation safety across the state, including New York City. The Orlow Firm has handled construction injury cases for more than 40 years. Machinery-guarding violations come up far more often than most workers realize. Below, we break down what the rule requires, what a violation looks like, and how it ties into New York's Labor Law.

What Is NYCRR § 23-1.12?

NYCRR § 23-1.12 deals with one specific hazard: the moving parts of power-driven machinery. Instead of a vague "be safe" standard, it spells out exact physical safeguards. Think guards, enclosures, sleeves, and railings. They have to be in place on certain kinds of equipment. The point is to keep hands, clothing, and bodies away from blades, spinning shafts, gears, belts, and pinch points.

The rule breaks down into seven lettered subsections, each covering a different type of equipment. Keep in mind that § 23-1.12 deals only with the physical guarding of machinery. Other parts of the Industrial Code handle related duties. For example, § 23-1.5 covers an employer's general safety responsibility, § 23-9.2 addresses the use of trained operators for power equipment, and § 23-1.8 governs personal protective equipment. These are companion rules, not part of § 23-1.12, and they are easy to mix up. This post stays focused on the machine-guarding rule itself. You can read the full regulatory text at the New York Industrial Code § 23-1.12 on Cornell LII.

The Seven Categories: What NYCRR 23-1.12 Guarding Requirements Actually Say

The heart of § 23-1.12 is its list of guarding requirements, one subsection at a time. Here is what each one calls for, in plain English alongside what the rule actually says.

(a) General power-driven machinery. Any power-driven machine not covered elsewhere in Part 23 must be guarded under Industrial Code Part (Rule No.) 19. That is the catch-all rule for guarding dangerous machinery. In short, if a machine has dangerous moving parts and no other rule covers it, this subsection still requires a guard.

(b) Keys, set screws, and similar projections. All keys, set screws, bolts, and similar projections on revolving parts must be countersunk or guarded. That includes shafts, pulleys, gears, and couplings. The rule allows two methods. One is a smooth cylindrical safety sleeve of wood or metal that fully surrounds the projection. The other is a fixed enclosure of sheet metal, wire mesh, expanded metal, or similar material. Any openings in that enclosure must be too small to pass a one-half-inch diameter ball. The reason is simple. A small projection on a fast-spinning shaft can catch a sleeve, a glove, or a finger and cause a severe entanglement injury.

(c) Power-driven saws. This subsection has three parts. Portable hand-held saws need a fixed guard above the base plate plus a movable, self-adjusting guard below it. Non-portable saws need a guard that covers the blade teeth and rises on its own as the material presses against it. The gap between the material and the underside of that guard cannot be more than one-half inch. Any teeth exposed beneath the table must also be guarded, and the saw needs an accessible cut-off switch. Finally, table circular saws used for ripping must have a spreader and an anti-kickback device. These rules exist because an unguarded saw blade is one of the most common causes of amputation and severe cuts on a job site.

(d) Sprockets and gears. Sprockets and gears must be fully enclosed, or covered with band guards. Those band guards extend over the periphery, with side flanges that reach below the roots of the teeth. Meshing gears create pinch points that can crush or amputate a hand in an instant.

(e) Belts, pulleys, and flywheels. Picture these moving parts less than seven feet above the ground, floor, or working platform. If their location does not already protect workers, they must be guarded. The guard can be a solid enclosure or a safety railing that keeps people at least 18 inches away. This seven-foot threshold applies only to subsection (e). It does not govern the other categories of machinery.

(f) Friction-disc drives. Friction-disc drives must be fully enclosed or fitted with band guards and side flanges, unless their design or location already protects workers.

(g) Wire rope nip points. The nip points between power winches or sheaves and wire ropes must be guarded. The guard must be a solid enclosure or a safety railing built to the standards in Part 23. A wire rope feeding onto a drum or around a sheave creates a powerful pinch point that can pull in and crush a hand.

Notice the pattern across all seven categories. The rule does not ask for general caution. It demands specific hardware: a sleeve here, an enclosure there, a railing at a set distance. That specificity is exactly what makes § 23-1.12 so important in the courtroom.

How NYCRR 23-1.12 Machinery Guard Violations Connect to Labor Law § 241(6)

A safety rule only helps an injured worker if it creates a path to accountability. That path runs through New York Labor Law § 241(6). This law puts a non-delegable duty on property owners and general contractors to follow specific parts of the Industrial Code. A non-delegable duty means they cannot escape responsibility by pointing to a subcontractor and saying it was someone else's job. You can review the statute at the New York State Senate — Labor Law § 241.

A violation of § 23-1.12 can support a § 241(6) claim when two things are true. First, the worker must point to a specific, concrete command in the rule that was broken. Not a general goal to be safe, but a definite requirement like "guard the saw blade" or "enclose the gears." Courts have long held that § 241(6) claims must rest on these concrete commands, and § 23-1.12 is full of them. Second, that violation must have been a proximate cause of the injury. In plain terms, the missing guard had to be a real reason the worker got hurt.

Here is what § 241(6) does not do. It is not strict liability. Comparative negligence applies, which means a worker's own carelessness can reduce the recovery. Under New York law, though, it does not wipe out the claim. A violation of § 23-1.12 does not guarantee a recovery on its own. It gives you a strong foundation that still has to be proven.

The most powerful part of § 241(6) for injured workers is who can be held responsible. Both the property owner and the general contractor carry the non-delegable duty, even if neither one directly employed the injured worker. So say a small subcontractor hires a laborer. That laborer can still bring a claim against the site owner and the general contractor when unguarded machinery causes the injury.

Common Violations and the Injuries They Cause

The categories in § 23-1.12 are not abstract. Each one maps to a real, predictable accident:

• A missing or removed guard on a portable circular saw leads to finger and hand cuts or amputations.
• An exposed rotating shaft with accessible set screws causes entanglement injuries, degloving, and fractures when a sleeve or glove gets caught.
• A belt-and-pulley system within seven feet of the floor and left unguarded produces crush and caught-in injuries.
• Sprockets or gears without enclosures pull in and amputate hands.
• An unguarded wire rope nip point near a winch causes pinch and crush injuries to the hands.

These are not freak accidents. They are the predictable result of skipping the specific hardware the rule requires. Just as troubling, many of these violations sit silently for months. The equipment runs every day without a problem until the moment it doesn't. Often the injured worker had no idea the machine was non-compliant in the first place.

Machinery injuries can be among the most life-altering on a job site. In our own practice, results have included a recovery for a worker who suffered a fingertip amputation at a worksite. That is the exact kind of contact injury that proper machine guarding is designed to prevent. Prior results do not guarantee a similar outcome.

What Injured Workers Should Do

Were you hurt by machinery on a New York construction site? A few steps can protect both your health and any future claim:

1. Seek medical attention right away. Beyond your health, prompt treatment creates a record tying the injury to the accident.
2. Report the accident to your employer in writing and keep a copy for yourself.
3. Photograph the machinery before you leave the site, if it is safe to do so. Focus on the guard, or the place where a guard should have been. Equipment is often repaired or replaced fast after an accident, and that photo may be the only proof the machine was non-compliant.
4. Preserve your clothing, gloves, and PPE from the day of the injury. These items can become evidence.
5. Do not give a recorded statement to the contractor's or owner's insurer before you get legal advice.
6. Talk to a construction accident attorney. New York's three-year statute of limitations for personal injury claims comes from CPLR § 214. That is the deadline to file your lawsuit. Workers' compensation deadlines are different and usually shorter, so it pays to understand both early.

If you are also getting or eligible for workers' compensation, you may have both a § 241(6) claim and a separate workers' comp claim. You can learn about filing a comp claim through the New York Workers' Compensation Board.

Frequently Asked Questions

What types of machinery does NYCRR § 23-1.12 cover?

It covers seven categories: general power-driven machines not addressed elsewhere, revolving parts with keys or set screws, power-driven saws, sprockets and gears, belts and pulleys and flywheels, friction-disc drives, and wire rope nip points. The common thread is exposed moving parts that can contact a worker on a construction site.

Who is responsible for guarding machinery on a New York construction site?

Under Labor Law § 241(6), property owners and general contractors carry a non-delegable duty to comply with the Industrial Code, including NYCRR § 23-1.12. That responsibility stays with them even when the work is performed by a subcontractor's employees, and they cannot pass it off by contract.

Can I sue if I was injured by an unguarded machine on a construction site?

Possibly. You may have a claim if two things are true: a specific requirement of § 23-1.12 was violated, and that violation was a proximate cause of your injury. The claim would fall under Labor Law § 241(6) against the owner or general contractor. Because comparative negligence applies, the strength of a claim depends on the facts. A consultation with a construction accident attorney is the right first step.

Does NYCRR § 23-1.12 apply if I work for a subcontractor?

Yes. The protections do not depend on who signs your paycheck. The owner's and general contractor's duties under Labor Law § 241(6) extend to all workers lawfully on the site, including employees of subcontractors. Your employer's identity does not limit your right to bring a claim.
