Caught-In/Between
Equipment That Starts Without Warning Kills
Catch the missing lockout before the machine wakes up
When workers service, clean, or clear a machine, the deadliest hazard is unexpected startup or stored energy releasing while a hand or body is inside. Without proper lockout/tagout, a machine can energize, cycle, or discharge and catch a worker in an instant. OSHA Scan analyzes photos of equipment under service to flag missing lockout devices, live energy sources, and exposed moving parts before anyone reaches in.

What this scenario looks like
An equipment contact incident is when a worker is caught, struck, or crushed by a machine that energizes, cycles, or releases stored energy during service or maintenance. The root cause is almost always a failure to isolate and lock out hazardous energy — electrical, hydraulic, pneumatic, mechanical, thermal, or gravitational — before the work begins.
On site the hazard shows up as a machine being cleaned or unjammed with the power still on, an energy-isolating device with no lock and tag applied, a raised load or ram held only by hydraulics, stored pressure in an accumulator or air line, or a coworker unaware that someone is inside the machine hitting the start button. Shared equipment with multiple servicers and no group lockout is especially dangerous.
The trap is that a de-energized-looking machine can still hold lethal stored energy — a spring, a raised platen, trapped pressure, or a capacitor. It looks safe right up until it moves. That is why verifying that every energy source is isolated and locked out, ideally confirmed from a photo before contact, is the core of preventing these incidents.

Why this scenario matters
Immediate consequences
Unexpected startup or energy release causes amputations, crushing, electrocution, burns, and death. A worker inside a machine has no chance when it cycles without warning.
Legal & financial impact
Lockout/tagout is one of OSHA's most-cited standards. A serious violation runs over $16,000, willful or repeat violations exceed $160,000, and a caught-in fatality can trigger criminal referral.
Operational impact
An energy-release incident stops production, triggers investigation, and can damage the equipment itself. Claims, downtime, and retraining costs far exceed the effort of proper lockout.
Industry-specific concerns
Manufacturing, packaging, food processing, utilities, and maintenance trades service powered equipment daily, often with multiple workers and shared machines that demand strict group lockout.
How OSHA Scan detects this hazard
OSHA Scan uses an AI vision model to assess service hazards. Upload a photo of equipment under service and it checks whether energy-isolating devices are locked and tagged, flags live sources, raised loads, and stored pressure, identifies exposed moving parts within reach, rates each hazard by severity, and cites the OSHA standard it may relate to — before anyone contacts the machine.

Real incident case study
A jam cleared with the power still on
The situation
A maintenance worker reached into a carton-forming machine to clear a jammed blank. He shut off the cycle at the operator panel but did not lock out the main disconnect, and a second worker at the line assumed the machine was ready to run.
What went wrong
The second worker pressed start to test the fix. The machine cycled while the first worker's hand was still inside, crushing his hand between the forming dies before he could pull free.
How OSHA Scan would have prevented it
A single photo of the machine before service run through OSHA Scan would have flagged the un-locked main disconnect as a critical hazardous-energy gap, cited 29 CFR 1910.147, and prompted the worker to apply a lock and tag and verify zero energy before reaching in.
Lessons learned
Turning a machine off at the panel is not lockout. Every energy source must be isolated, locked, tagged, and verified at zero energy before any body part enters — a fast photo scan confirms the locks are on.
Prevention best practices
Layered controls, from most to least effective.
Engineering controls
Make it physically impossible for the equipment to move during service.
- Provide lockable energy-isolating devices on every machine energy source
- Install blocks, pins, or stands to support raised loads, rams, and platens
- Bleed and lock out hydraulic, pneumatic, and accumulator pressure
- Use interlocked guards that require de-energization to open
- Fit dissipation paths for stored electrical energy such as capacitors
Administrative controls
Run the lockout/tagout program that governs every service task.
- Develop machine-specific lockout procedures listing every energy source
- Require lock, tag, and verified zero energy before any service or cleaning
- Use group lockout with individual locks when multiple workers service a machine
- Assign personal locks and keys that only the applying worker can remove
- Conduct annual authorized-worker retraining and procedure audits
Personal protective equipment
Protection for workers performing service and maintenance.
- Personal lockout locks, tags, and hasps for each authorized worker
- Insulated tools and arc-rated PPE where electrical energy is present
- Close-fitting clothing and no jewelry near any moving parts
- Eye, hand, and hearing protection appropriate to the task

Frequently asked questions
What is an equipment contact incident?
It is when a worker is caught, struck, or crushed by a machine that starts up unexpectedly or releases stored energy during service, cleaning, or maintenance — almost always because hazardous energy was not locked out.
Is turning a machine off the same as lockout?
No. Turning a machine off at the controls does not prevent someone else from restarting it or stored energy from releasing. Lockout means isolating each energy source, applying a lock and tag, and verifying zero energy.
What counts as hazardous stored energy?
Electrical charge in capacitors, hydraulic and pneumatic pressure, springs under tension or compression, raised loads or rams held by gravity, and thermal energy can all injure a worker even after the main power is off.
When is lockout/tagout required?
OSHA requires lockout/tagout (29 CFR 1910.147) whenever servicing or maintaining equipment where unexpected energization or stored-energy release could injure a worker, including clearing jams and cleaning.
What is group lockout?
When multiple workers service one machine, each applies their own personal lock to a group lockout device. The equipment cannot be re-energized until every worker removes their own lock, so no one is left exposed.
Who is allowed to remove a lockout device?
Only the authorized worker who applied a given lock may remove it, using their own key. Removal by anyone else is prohibited except under a strict documented exception when that worker is unavailable.
What are the OSHA penalties for lockout failures?
A serious lockout/tagout violation can cost over $16,000, and willful or repeat violations can exceed $165,000 per instance. Resulting amputations or fatalities require prompt OSHA reporting.
How accurate is OSHA Scan at detecting lockout gaps?
OSHA Scan flags hazardous-energy gaps. It checks for applied locks and tags, live sources, and stored energy, returning the location and OSHA citation.

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
OSHA Scan gives an AI-assisted preliminary review from a photo. It does not replace an on-site inspection by a qualified safety professional, and a compliance score is not an official OSHA determination.
