HySafety 7882 is a structural firefighting protective glove designed around a multi-layer protection concept (outer shell + moisture barrier + thermal liner + reinforced stitch system). For structural firefighting PPE, performance is not determined by a single component; rather, it depends on how the integrated material system responds to heat exposure, flame contact risk, moisture/contamination conditions, and mechanical stress during operation.

1) Protection System Architecture (Layered Construction)

1.1 Outer Shell (Out shell)

• Material: Eversoft cowhide
• Functional role: Primary mechanical protection and flame/heat resistance support.
• Key properties (as specified):
  • Durable and soft hand feel
  • Water repellent / low water absorption
  • Washable while maintaining softness after washing
  • Heat resistance and flame retardant
  • High abrasion resistance, tear resistance, and puncture resistance

Technical implication: The outer shell reduces direct impact from heat, abrasion, and puncture sources while limiting moisture uptake, which helps downstream layers maintain their protective function.

1.2 Moisture Barrier

• Material: Porelle® 
• Functional role: Moisture/contamination barrier with flame retardant moisture barrier performance, supporting protection against chemical and bloodborne pathogen contamination routes (per stated claims).
• Key properties (as specified):
  • Durable and breathable
  • Flame retardant moisture barrier function

Technical implication: In operational environments where moisture transfer is likely, barrier performance is critical because absorbed moisture can degrade thermal insulation effectiveness and increase heat transfer to the hand.

1.3 Thermal Liner

• Material: Kovenex® 
• Functional role: Thermal insulation and heat resistance with breathability.
• Key properties (as specified):
  • Breathable
  • High heat resistance

Technical implication: The thermal liner is responsible for limiting heat transfer over time. Its performance works in conjunction with the moisture barrier to sustain protective behavior under wet or contaminated conditions.

1.4 Stitching System

• Stitch material: Kevlar® stitches
• Functional role: Reinforcement of seam integrity to improve durability under stress.

Technical implication: Seam failure is a common weakness in glove systems; reinforced stitching contributes to maintaining overall structural integrity over repeated use.

2) Structural Performance Indicators (Test Items)

The structural protection performance for HySafety 7882 is presented using key test indicators shown in the provided materials:

• TPP Rating (cal/cm²)
  • Request: ≥ 35
  • Test result: > 60
• Time to Second-Degree Burn (s)
  • Request: > 10
  • Test result: 10.7 – 29.0
• Time to Pain (s)
  • Request: > 6
  • Test result: 8.1 – 13.1

Technical interpretation:

• TPP is an integrated measure reflecting thermal protection against heat flux over a defined exposure.
• Time to second-degree burn and time to pain provide additional practical indicators for heat-driven skin damage thresholds and subjective pain onset.

3) Operational Design Features Relevant to Mechanical Use

• Elastic wrist: Helps maintain fit stability and reduces exposure gaps during movement.
• Roll-over seamless fingertips: Supports mobility, improves fingertip comfort, and enhances control when operating equipment.
• Cowhide palm reinforcement: Improves abrasion resistance in high-contact zones.

4) Compliance Note (PFAS Statement)

The provided product information includes a statement regarding PFAS: total fluorine concentration not more than 100 ppm. This is included to support environmental communication and procurement documentation needs.

5) Sizing Information

NFPA sizes: 64N | 70N | 70W | 76N | 76W | 82N | 82W | 82XW
Manufacturer sizes: XXS | XS | S | M | L | XL | XXL | XXXL

6) Conclusion (Technical Summary)

HySafety 7882 is engineered as a structural firefighting protective glove system. Its layered construction—Eversoft cowhide outer shell + Porelle® moisture barrier + Kovenex® thermal liner, reinforced by Kevlar® stitching—is supported by the provided thermal protective test indicators (TPP > 60 cal/cm², second-degree burn time 10.7–29.0 s, and pain onset 8.1–13.1 s). The design features further support operational dexterity and mechanical durability under firefighting task conditions.
