Welcome to The Safety Desk, Product Safety Consulting’s FAQ series dedicated to answering the most common and critical questions in product safety and regulatory compliance
There are a few things in life that can derail a perfectly pleasant Tuesday: inclement weather, flat tires, and getting a piece of industrial equipment red-tagged by an inspector. One minute your facility is humming along, and the next minute an AHJ—Authority Having Jurisdiction, a fancy term for “the person with the power to shut you down”—has slapped a big metaphorical NOPE on your equipment, bringing operations to a grinding halt.
Projects stall, operators stand around waiting for answers, and management starts asking the same question in 37 slightly different ways: “How quickly can we get this fixed?” The good news: red tags don’t have to turn into a weeks-long crisis. This is precisely why field evaluations exist. They’re the ultimate “get out of red-tag jail fast” card. Think of them as an on-site certification option designed to get your equipment compliant, labeled, and legally operating again, all without dragging it out of your building.
This is exactly where Product Safety Consulting’s 48-hour onsite field evaluation response becomes a lifesaver, getting you back on the right side of compliance and getting equipment online with minimal downtime.
Let’s walk through what field evaluations actually are, why they’re a lifesaver when the unexpected happens, and what you can expect when bringing one in to save the day.
What Is a Field Evaluation?
A field evaluation is basically certification on wheels. Instead of sending your equipment off to a testing lab (which only works for manufacturers or anyone with infinite time and no operational deadlines), a qualified evaluator comes to you.
They assess installed or in-use equipment that doesn’t have proper North American certification, including:
- Imported equipment that arrived without the right mark
- Custom-built machinery that never went through a lab
- Equipment that somehow slipped through installation without documentation
- Anything that’s been red-tagged by an inspector
Think of it as the house call version of product certification. All the expertise, none of the packing peanuts. PSC specializes in these onsite evaluations, arriving quickly, assessing compliance, and issuing field labels that AHJs accept without hesitation.
What Does Red-Tagged Really Mean?
A red tag isn’t a kiss of death by any means, but it is a mandate.
It means an AHJ (think building inspector, fire marshal, OSHA inspector, etc.) has determined your equipment is non-compliant with safety standards and can’t operate until the issue is resolved.
Besides being incredibly unsafe, running red-tagged equipment has the added bonus of being illegal. So unless your business objectives include hemorrhaging money, painstaking shutdowns, and a potential side of jailtime, rapid response matters. Field evaluations are a lifesaver, on each of these fronts.
How Fast Can a Field Evaluation Happen?
Faster than most people expect. PSC in particular abides by a 48-hour or less response time for getting an evaluator onsite. In the world of halted operations and mounting downtime costs, that’s basically overnight delivery for compliance.
Most evaluations take just one site visit, though complex equipment or multiple units can slow things slightly. Still, we’re talking days, not months.
Compare that to dismantling and shipping the equipment to a traditional testing lab, waiting for evaluations, and reinstalling everything. For most manufacturers, it’s a no brainer.
Field Evaluation vs. Certification Lab: What’s the Difference?
Both involve safety standards, with some marked differences.
Traditional Certification
- Happens before equipment hits the market
- Conducted at an NRTL’s testing lab
- Applies to all units of a product line
- Includes factory inspections and ongoing surveillance
- Makes perfect sense for manufacturers
Field Evaluation
- Happens on-site
- Applies to one specific piece of installed equipment
- One-time certification; no factory audits
- Uses the same safety standards but tailored to your actual installation
Translation: field evaluations are the practical choice when the equipment is already in your building and shutting it down is costing you money by the minute.
Will Inspectors Actually Accept a Field Evaluation Label?
That’s a resounding yes. Field evaluations aren’t a workaround or a good luck charm. They’re a sure thing. A properly conducted field evaluation is recognized across North America and accepted by all AHJs. Evaluators follow the same standards used in traditional certification, and their labels carry weight because they verify compliance on-site.
Once the evaluation is complete and the label is affixed, inspectors get exactly what they need to clear the equipment for operation.
What Kinds of Equipment Qualify for Field Evaluations?
The list is fortunately lengthy. Field evaluations cover a wide range of low- and medium-voltage equipment, including:
- Industrial control panels
- HVAC systems
- Commercial appliances
- Lighting fixtures
- Medical equipment
- Laboratory equipment
- Information Technology equipment
- Custom machinery or one-off installations
The main requirement is that evaluators must be able to assess construction, components, and safety features either on-site or with limited off-site testing. If it’s installed, important, and holding up your operations, chances are a field evaluation is your ace in the hole.
Is it Cheaper than Traditional Certification? (Spoiler: yes!)
If you’re certifying a single installation or a handful of units, the cost difference is… well, let’s just say noticeable.
Field evaluations often save tens of thousands of dollars compared to sending equipment to a lab and going through full product certification. Plus, you avoid logistical costs: dismantling, shipping, downtime, reinstalling, and more downtime.
In short: If this is a one-off or custom build, field evaluation is almost always the budget-friendly choice.
Can You Evaluate Multiple Units at Once?
Definitely. If you have five identical units, twenty similar panels, or a production floor full of nearly identical equipment, evaluating them together is more efficient and cost-effective.
One visit, multiple certifications, less downtime. Productivity managers everywhere rejoice.
What Standards Are Used?
Field evaluations follow the same safety standards used in traditional certification programs. Some common examples:
- UL 508A – Industrial control panels
- UL 1598 – Lighting fixtures
- UL 60335 – Appliances
- UL 60601 – Medical equipment
- UL 61010 – Laboratory equipment
- UL 62368 – IT and A/V equipment
Your evaluator is the voice of reason when it comes to which standards apply based on how the equipment is used and where it’s installed.
What Actually Happens During the Evaluation?
Here’s the play-by-play:
- On-site inspection of construction, wiring, components, and installation
- Verification of compliance with relevant UL and safety standards
- Non-destructive testing (don’t worry, no smashing things)
- Checks for grounding, spacing, enclosure integrity, protective features, etc.
- Documentation & field evaluation label applied once everything meets requirements
And no need to hit the panic button if you don’t pass upon first inspection. The evaluator will check your work and outline exactly what needs to be corrected for certification.
The Final Word on FEs
Getting red-tagged is hair-raising, and for good reason. But it doesn’t have to become a full-blown operational disaster. Field evaluations exist for exactly these situations: when you need fast, practical, in-place certification without tearing your facility apart or torpedoing your schedule.
If you’re on the wrong end of a red tag, dealing with uncertified imported equipment, or trying to avoid compliance surprises before a big inspection, a field evaluation is one of the smartest tools at your disposal.
Reverse your red tag by putting PSC’s 36+ years of experience with FEs to work for you.
