Machine guarding is the most cited standard in metal and nonmetal mining, and it isn't close. Every exposed pulley, unguarded coupling, or missing belt shield is a citation waiting to happen, and worse, a hand or sleeve away from a serious injury. The frustrating part is that most guarding failures aren't caused by a lack of guards. They're caused by a guard that was removed for maintenance and never bolted back, or one that was never inspected closely enough to notice it had come loose.

Why Guarding Keeps Topping the MSHA Citation List

Moving machine parts, covered under 30 CFR §56/57.14107, has held the position of the most-cited standard in metal and nonmetal mining for years running. The rule itself is simple: any part capable of causing injury through contact, gears, pulleys, couplings, shafts, fan blades, and similar moving components, has to be guarded unless it sits at least seven feet from a walking or working surface. The violations aren't usually about a mine skipping guards entirely. They're about guards that were compromised somewhere along the way.

The Three Types of Guarding an Inspection Has to Confirm

Not every hazard is protected the same way, and a proper inspection checklist has to know the difference. Point-of-contact guarding covers the exact pinch point. Location guarding relies on distance or placement to keep a hazard out of reach. Area guarding encloses a broader zone. An inspection that treats all three the same way misses defects specific to each type.

Point-of-Contact Guards

These sit directly over the hazard, the nip point between a belt and pulley, or the gap where a chain meets a sprocket. Inspectors need to confirm the guard is bolted down, undamaged, and actually covering the full contact zone, not just partially shielding it.

What gets missed here

A guard that covers the front of a pinch point but leaves the back or side accessible still allows contact. This is one of the most common reasons a "guarded" component still generates a citation.

Location Guarding

Some components are protected simply by being out of normal reach, behind a barrier, above head height, or beyond the seven-foot exemption distance. An inspection has to verify that distance hasn't changed, since a platform, ladder, or new walkway added later can bring a miner back within reach of an unguarded part.

Area Guarding

Larger hazard zones, like an entire conveyor drive unit, get enclosed rather than individually shielded. These guards need regular checks for corrosion, loose panels, and access doors that aren't latching properly, since a single weak point defeats the whole enclosure.

Guarding Inspection Software vs. a Paper Walkaround

A paper walkaround catches obvious problems, a guard sitting on the ground next to the machine. It rarely catches the subtler failures, a guard that's back in place but not fully secured, or a repeat issue on the same unit that no one has connected across three separate inspections.

The Guarding Checklist Every Inspection Should Walk Through

The components below make up the bulk of guarding citations across mining equipment. A digital checklist should prompt an inspector through each one, rather than leaving it to a general "guards okay?" line item.

How FleetRabbit Handles Machine Guarding Inspections

FleetRabbit's guarding inspection module was designed around how mining equipment actually gets guarded, point-of-contact, location, and area guarding all tracked as distinct categories, not a single generic line item that gets rubber-stamped every shift.

Equipment-Specific Guarding Checklists

Each machine type, conveyors, crushers, haul trucks, drills, gets a checklist built around its actual guarding points, so an inspector walking a conveyor sees pulley and idler prompts, not a generic list built for a completely different machine.

Photo evidence tied to every flagged guard

When an inspector marks a guard as missing, loose, or damaged, the app requires a photo before the item can be closed out, creating a visual record that holds up during an MSHA review.

Repeat-Defect Pattern Tracking

If the same guard on the same machine keeps coming back as a defect across multiple inspections, FleetRabbit surfaces that pattern automatically, pointing maintenance teams toward a root cause instead of a repeated quick fix.

Offline Inspections, Anywhere on Site

Whether the inspection happens underground, on a remote bench, or in a shop with no signal, the checklist works fully offline and syncs the moment connectivity returns, so no guarding defect goes unrecorded because of a dead zone.

Frequently Asked Questions

Turn Guarding From Your Top Citation Risk Into a Tracked Process

Guarding doesn't stay compliant on its own. Every maintenance job, every reinstalled panel, every guard bolted back after a repair is a chance for something to slip. A digital checklist built around the exact standard inspectors check first turns that risk into something visible, provable, and fixable before it becomes a citation.
