Machine Safety & Guarding

Spot visible guarding gaps before an injury occurs.

Use image review to prompt a machine-specific inspection, then verify guarding, controls, energy isolation, and training with qualified personnel.

Try it on a machine safety & guarding photo

OSHA Scan may flag visible concerns. A photo may flag an apparently exposed moving part or missing guard, but it cannot verify guard dimensions, interlocks, stopping time, hidden energy, lockout/tagout, or a zero-energy state.

1

Set the scene

Start with context

Fill the frame

2–3 ft for close-ups; keep ladders, cords and workers fully in view.

2

Capture clearly

Make the frame usable

Light it right

Keep the sun or lights behind you — glare and shadows hide hazards.

Tap to focus

Tap the hazard on screen and hold still one second — blur can't be flagged.

3

Choose the useful view

Give the AI room to understand

Go landscape

Turn your phone sideways — a wider frame catches more of the scene.

Only upload photos you have permission to use, and avoid images showing personal, customer, or confidential information. Demo photos and results are held privately for up to 48 hours so you can save them to a free account; unclaimed photos are deleted automatically. Results are an AI-assisted preliminary review, not an official OSHA determination.

What the AI can and can't detect

OSHA Scan reads a single photo. That makes it fast and easy for anyone on site — but it also means it has real limits. Here's an honest look at both.

What it can catch from a photo

  • Missing or incorrect PPE that is visible in the frame
  • Unprotected edges, open holes, and visible fall hazards
  • Housekeeping, trip, and blocked walkway or exit hazards
  • Visible electrical, struck-by, and equipment-guarding hazards

What a photo can't tell it

  • Hazards hidden from view or anything outside the photo
  • Exact heights, distances, weights, or measurements
  • Training records, procedures, or how equipment is actually used
  • Full legal compliance or an official OSHA pass/fail determination
A photo may flag an apparently exposed moving part or missing guard, but it cannot verify guard dimensions, interlocks, stopping time, hidden energy, lockout/tagout, or a zero-energy state.

Important Limitation: A photo may flag an apparently exposed moving part or missing guard, but it cannot verify guard dimensions, interlocks, stopping time, hidden energy, lockout/tagout, or a zero-energy state.

Quick Answer

Machine guarding uses barriers, devices, and safe work practices to protect people from point-of-operation, nip-point, rotating-part, flying-chip, and spark hazards. Servicing that exposes hazardous energy also requires an energy-control program.

Reference: 29 CFR 1910.212; 29 CFR 1910.147

Understanding Machine Hazards

A machine's point of operation, power-transmission parts, rotating parts, chips, sparks, and unexpected movement can injure operators and nearby workers. Guarding must prevent contact without creating a new hazard or interfering with safe operation.

Guarding and lockout/tagout are related but distinct. A visible guard does not prove safe servicing, and a lock or tag in a photograph does not prove all hazardous energy was isolated and verified.

Visual Checks for Machine Guards

The reviewed scene shows an exposed belt and pulley assembly. Visual review can flag similar visible conditions for an in-person machine-specific assessment.

1

Exposed transmission parts

Flag visibly exposed belts, pulleys, gears, shafts, or nip points where contact appears possible.

2

Point of operation

Note an apparently unguarded work area and route the finding to the machine owner or safety professional.

3

Guard condition

Record missing, damaged, displaced, or apparently defeated guards; do not infer interlock function from appearance.

4

Work-area context

Flag clutter, reach-through access, or nearby people for a task and safeguarding review.

Safeguarding Machinery

The reviewed scene shows a guarded machine and operator control area supporting a preventive review workflow.

Fixed or adjustable guards

Use secure barriers and safe distances appropriate to the machine and task.

Interlocks and presence sensing

Use engineered devices where appropriate and have qualified personnel test their function; a photo cannot verify performance.

Energy-control procedures

For servicing or maintenance, identify, isolate, lock/tag, release or restrain stored energy, and verify according to the written procedure.

Repair and inspect

Remove damaged or missing guards from service until corrected, then document the inspection and authorization to resume.

Machine-Safety Training

Training must match the machine, role, guard design, and energy-control procedure.

  • Identify the hazards and safeguards for each machine and operation
  • Use safeguards as intended and understand when removal is permitted and by whom
  • Train authorized, affected, and other employees on the site's energy-control roles
  • Report missing, damaged, bypassed, or ineffective safeguards and stop unsafe work

Documenting Machine Safety

Keep the machine/task hazard assessment, guard and interlock inspection, energy-control procedure, authorized/affected employee training, maintenance work order, corrective action, and restart authorization. Attach a dated photo only to document the visible observation and its follow-up.

A photo cannot prove a lockout, de-energization, interlock test, emergency-stop function, or zero-energy state. Those require the written procedure and physical verification by trained personnel.

Photo-based reviews support documentation. Your responsible program owner must arrange on-site verification by people with the qualifications and designated roles required for the task.

Frequently Asked Questions

Q.Can visual AI confirm that a machine is locked out?

A.No. A photograph cannot verify isolation, stored-energy control, or zero energy. Follow the site's written 1910.147 procedure and have a trained person verify it.

Q.What is the point of operation?

A.It is the area where work is performed on the material being processed. The applicable machine guard must protect people exposed to that operation.

Q.Can a photo prove an interlock works?

A.No. It may show the visible guard or device, but function, stopping performance, and safe integration require a physical test by qualified personnel.
