NFPA 70B Infrared Inspection Requirements: What Happens If You Don’t Comply?

Electrical maintenance standards have changed — and many facilities haven’t caught up.

With the 2023 update to NFPA 70B, infrared thermography inspections are no longer optional best practice — they are a core requirement of condition-based electrical maintenance programs.

But here’s the real question facility managers are asking: What actually happens if we don’t comply?

At Assured NDT, we’re seeing a growing gap between facilities that are proactive — and those unknowingly exposing themselves to fire risk, compliance issues, and insurance problems.

This guide explains the real-world impact of NFPA 70B infrared inspection requirements — and why waiting is a costly mistake.

Quick Answer

Are infrared inspections required under NFPA 70B?

Yes. NFPA 70B requires condition-based maintenance programs that include diagnostic tools such as infrared thermography to evaluate energized electrical equipment and detect developing failures.

What Changed in NFPA 70B (2023 Update)

The biggest shift:

➡ Electrical maintenance is now condition-based, not time-based

This means facilities must:

• Monitor actual equipment condition

• Use diagnostic tools (like infrared thermography)

• Identify problems before failure

Annual infrared inspections are now a core expectation — especially for energized systems.

Why Infrared Inspections Are Required

Electrical failures don’t happen instantly.

They develop over time through:

• Loose electrical connections

• Increasing resistance

• Heat buildup

• Insulation breakdown

• Load imbalance

Infrared thermography detects heat — the earliest warning sign of failure.

Without it, facilities are effectively operating blind.

⚠️ What Happens If You Don’t Comply with NFPA 70B?

This is where this blog will outperform your current one — we’re answering the question people actually care about.

1. Increased Risk of Electrical Fires

Electrical failures are the #1 cause of commercial fires.

Without infrared inspections:

• Overheating connections go undetected

• Equipment degrades unnoticed

• Fire risk increases significantly

2. Higher Insurance Scrutiny (and Cost)

Insurance carriers are increasingly asking for:

• Infrared inspection reports

• Maintenance documentation

• Electrical risk mitigation plans

Without these:

• Premiums may increase

• Coverage may be limited

• Claims may be challenged

3. OSHA Exposure

While OSHA doesn’t name NFPA 70B directly, it requires:

• Hazard identification

• Safe work practices

• Electrical risk mitigation

Failing to inspect electrical systems can be interpreted as failure to identify hazards.

4. Unexpected Downtime

Hidden electrical issues lead to:

• Equipment failure

• Production loss

• Emergency repairs

• Revenue impact

Infrared inspections shift maintenance from reactive → proactive.

5. Liability in the Event of an Incident

If an electrical failure causes:

• Injury

• Fire

• Equipment damage

Investigations often look for:

➡ Was the system properly maintained?

➡ Were inspections performed?

No documentation = higher liability.

What NFPA 70B Infrared Inspection Requirements Actually Include

A compliant infrared inspection program should include:

✔ Annual inspection of energized equipment

✔ Certified thermographers

✔ Thermal imaging documentation

✔ Delta-T (temperature differential) analysis

✔ Severity classification

✔ Corrective action recommendations

✔ Maintenance tracking

Anything less is incomplete.

Equipment That Must Be Inspected

Most commercial facilities should include:

• Switchgear

• Electrical panels

• Transformers

• Motor control centers

• Bus ducts

• Generators

• UPS systems

• HVAC electrical systems

These are the highest-risk components.

Key Takeaways for Facility Managers

• NFPA 70B requires condition-based electrical maintenance

• Infrared thermography is essential for detecting hidden failures

• Annual inspections are now a baseline expectation

• Insurance carriers are increasingly requiring IR reports

• Failure to comply increases fire, downtime, and liability risk

FAQs: NFPA 70B Infrared Inspection Requirements

1. Are infrared inspections required by NFPA 70B?

NFPA 70B requires condition-based maintenance programs that include diagnostic inspections such as infrared thermography for energized electrical systems.

2. How often should infrared inspections be performed?

Most facilities perform infrared inspections annually to align with NFPA 70B expectations.

3. What happens if a facility does not perform infrared inspections?

Facilities face increased fire risk, higher insurance scrutiny, potential OSHA exposure, and greater liability in the event of an incident.

4. Who is qualified to perform infrared inspections?

Certified Level II or Level III thermographers using calibrated thermal imaging equipment.

5. Do insurance companies require infrared inspections?

Many insurance carriers now request infrared inspection reports as part of risk assessment and underwriting.
