A pair of structural firefighter gloves without NFPA 1971 certification is not structural firefighter gloves. The label is the difference between a glove that has been independently tested for thermal protection, conductive heat resistance, dexterity, and bloodborne pathogen barrier integrity, and a glove that has not.
This guide covers what NFPA 1971 tests, how the standard changed when it folded into NFPA 1970 in the 2024 edition, how to verify your gloves are certified, and when certification expires.
A companion guide on NFPA 1971 and NFPA 1977 fire boots covers the equivalent standards for structural and wildland boot certification.
What is NFPA 1971?
Quick Answer: NFPA 1971 is the National Fire Protection Association standard for protective ensembles used in structural firefighting and proximity firefighting. It sets the minimum requirements for thermal protection, moisture barrier integrity, glove construction, and dozens of other criteria. As of the 2024 cycle, NFPA 1971 was consolidated into NFPA 1970, but the testing requirements for gloves remain substantively the same.
The full title of the legacy standard is NFPA 1971, Standard on Protective Ensembles for Structural Fire Fighting and Proximity Fire Fighting. The current consolidated standard, NFPA 1970, covers what were previously NFPA 1971 (PPE), 1975 (station and work uniforms), 1981 (SCBA), and 1982 (PASS devices) under one document.
Gloves in service with labels reading "NFPA 1971-2013" or "NFPA 1971-2018" remain compliant. New gloves manufactured under the 2024 cycle will reference NFPA 1970.
What does NFPA 1971 test on a glove?
Six categories of testing matter most for gloves:
Thermal Protective Performance (TPP). Measures the time-to-second-degree-burn under simulated flashover conditions. The minimum NFPA 1971 threshold is 35. Premium gloves exceed 60.
Conductive Heat Resistance. Tests how the glove handles contact with a 500°F surface. The standard requires the glove to limit the wearer’s skin temperature increase to 24°C above ambient over a defined exposure period.
Liquid penetration resistance. Verifies the moisture barrier blocks water, blood, and common chemicals from penetrating to the wearer’s skin. This test is what separates a true structural glove from a heat-resistant work glove.
Viral penetration resistance. Tests the moisture barrier against viral pathogens. NFPA 1971 references ASTM F1671 for viral penetration testing.
Cut and puncture resistance. The palm and back-of-hand panels must resist defined puncture and cut loads. Most certified gloves exceed the minimum by a wide margin because real fireground hazards (broken glass, nail boards, wire) demand it.
Hand function and dexterity. A standardized test where firefighters perform a series of manipulation tasks (gripping, knot tying, tool handling) wearing the glove. Failure to complete the tasks within defined time limits disqualifies the glove from certification.
The four glove construction layers required by NFPA 1971
Every NFPA 1971-certified structural glove uses a layered construction:
-
Outer shell. Leather (cowhide, goatskin, kangaroo, water buffalo) or treated synthetic. Provides abrasion resistance, cut resistance, and the first thermal layer.
-
Moisture barrier. A waterproof breathable membrane (Porelle PTFE, H2X+, CROSSTECH, or equivalent). Blocks water, chemicals, and bloodborne pathogens while allowing perspiration to evaporate.
-
Thermal liner. Aramid felt, Kovenex, or modacrylic batting. The TPP rating depends almost entirely on the thermal liner construction.
-
Inner liner. Modacrylic, Nomex knit, or treated cotton. The layer that touches the wearer’s skin. Determines comfort, don/doff speed, and how the glove handles repeated washing.
How to verify a glove is NFPA 1971 certified
Quick Answer: Look inside the glove cuff for a permanent label that lists the NFPA standard (1971-2013, 1971-2018, or 1970), the certifying organization (typically UL, SEI, or Intertek), the manufacturer name, the model, the size, the manufacture date, and the country of origin. The label must be present, legible, and permanent. Verbal claims, online product descriptions, and box labels are not sufficient.
Three details matter on the cert label:
-
Standard edition. "NFPA 1971-2013" and "NFPA 1971-2018" both meet compliance for gloves in service today. "NFPA 1970" is the consolidated 2024 standard. Anything older than 2013 is past the typical 10-year retirement window.
-
Certifying body. UL (Underwriters Laboratories) and SEI (Safety Equipment Institute) are the most common third-party certifiers. The cert body name and logo should be visible.
-
Manufacture date. NFPA 1851 sets a 10-year retirement window from manufacture date for structural PPE, including gloves. A glove manufactured in March 2014 must be retired by March 2024 regardless of how often it has been worn.
When NFPA 1971 gloves expire
Quick Answer: NFPA 1851, Standard on Selection, Care, and Maintenance of Protective Ensembles for Structural Fire Fighting and Proximity Fire Fighting, requires retirement of structural firefighting gloves no later than 10 years from the date of manufacture. Departments may retire earlier based on visual inspection, palm wear-through, seam failure, or moisture barrier compromise.
Five inspection points to check during routine PPE checks:
-
Palm wear-through, especially at the thumb saddle and the index finger pad.
-
Seam separation between the outer shell and the cuff, or along the finger sidewalls.
-
Moisture barrier compromise. A glove that no longer beads water on the outer shell, or that wets through to the inner liner during a routine wash, has likely failed.
-
Thermal liner bunching or shifting. The liner should sit smoothly against the inside of the outer shell. Bunching reduces the effective TPP and creates burn-through risk.
-
Cuff damage. A torn gauntlet cuff or a broken knit wristlet defeats the debris-management function regardless of the rest of the glove’s condition.
Any glove failing one or more of these inspection points should be retired even if the manufacture date is within the 10-year window.
How to read a glove specification sheet
Manufacturer specification sheets typically list four numbers worth checking before purchase:
-
TPP score. Higher is better for thermal protection. NFPA minimum is 35; premium gloves rate 60 to 80.
-
Conductive Heat Resistance time. Reported in seconds at a defined surface temperature. Longer times indicate better protection against gripping hot tools and surfaces.
-
Cut resistance level. Reported under CE EN388 (Levels 1-5) and/or ANSI/ISEA 105 (Levels A1-A9). For structural gloves, Level 3 or A4 and above is typical.
-
Wash cycle compliance. Some gloves are validated for repeated NFPA 1851 wash cycles; others lose certification after machine washing. Departments running mandatory PPE laundering programs should verify wash compliance before purchase.
NFPA 1971 vs NFPA 1977 gloves
The two standards cover different operational profiles:
-
NFPA 1971 / 1970 (structural). Built for IDLH atmospheres, sustained flashover exposure, conductive heat from hot tools, and bloodborne pathogen contact. Heavier, with thermal lining and a moisture barrier.
-
NFPA 1977 (wildland). Built for extended-duration outdoor firefighting where heat exposure profiles are lower but durations are longer. Lighter, no moisture barrier, no heavy thermal lining. Better breathability and flexibility for hand-line work.
A glove certified to one standard is not automatically certified to the other. For wildland response, see the Wildland Gloves collection. For interior firefighting, the Structural Gloves collection carries every NFPA 1971-certified pair we stock.
FAQ
Is NFPA 1971 still a valid standard?
Quick Answer: Yes for gloves in service today. The NFPA 1971-2013 and 1971-2018 editions remain compliant for structural firefighting use until they reach the 10-year retirement window per NFPA 1851. New gloves manufactured under the 2024 cycle reference NFPA 1970, the consolidated standard.
Can I wear NFPA 1971 gloves for wildland firefighting?
Quick Answer: Technically yes for short exposures, but not optimal. NFPA 1971 gloves are heavier, less breathable, and lack the flexibility for sustained hand-tool work in wildland environments. NFPA 1977 wildland gloves are the appropriate certification for brush, forest, and grass fires. For mixed-response departments, issuing both pairs is standard practice.
Do NFPA 1971 gloves protect against electrical hazards?
Quick Answer: No. NFPA 1971 does not include electrical hazard testing. Structural firefighting gloves are not rated for electrical work. For electrical hazard protection, look for ASTM D120 rubber insulating gloves with appropriate voltage class ratings.
Are NFPA 1971 gloves bloodborne pathogen rated?
Quick Answer: Yes when the moisture barrier is intact. NFPA 1971 requires viral penetration testing per ASTM F1671 as part of certification, which means a new or properly maintained glove provides BBP protection. A glove with compromised moisture barrier integrity (visible cracking, fluid wetting through to the inner liner) no longer provides this protection and should be retired.
What is the difference between NFPA 1971 and NFPA 1851?
Quick Answer: NFPA 1971 is the design and certification standard for structural firefighting PPE. NFPA 1851 is the operational standard for selection, care, and maintenance of that PPE. NFPA 1971 says what the glove must be at manufacture; NFPA 1851 says how often to inspect, when to wash, when to retire, and how to document the lifecycle.
