[20250709] What risks does protective clothing with weaker outer shell pose to firefighters?
If the outer shell of a EN 469 firefighting suit is weaker in tear strength, tensile strength, residual tensile strength, and dimensional stability (dimensional change), it can pose serious risks to firefighters during emergency operations. Here's how each weakness could impact safety :
1. Tear Strength (Resistance to Ripping)
Risk :
🔺 A fabric with poor tear strength can rip easily when caught on sharp edges (like metal, glass, or debris at a fire scene).
Consequence :
🔺 Sudden exposure of inner protective layers or skin
🔺 Increased chance of burn injury
2. Tensile Strength (Resistance to Stretching or Breaking Under Tension)
Risk :
🔺 Low tensile strength means the fabric can stretch or break under stress, such as pulling, dragging, or when wearing heavy equipment.
Consequence :
🔺 Suit deformation, compromising fit and mobility
🔺 Possible seam failures
🔺 Greater chance of garment failure during active firefighting
3. Residual Tensile Strength (Strength After Exposure to Heat/Flame)
Risk :
🔺 If the fabric loses strength after thermal exposure (e.g., direct flame or high heat), it becomes brittle or weak.
Consequence :
🔺 Reduced structural integrity in high-heat areas
🔺 Critical failure during flashover or backdraft conditions
🔺 Inner layers more likely to be compromised
4. Dimensional Change (Shrinkage or Deformation After Washing/Heat)
Risk :
🔺 Poor dimensional stability can lead to significant shrinkage or misshaping after washing, drying, or heat exposure.
Consequence :
🔺 Tightness or misfit, restricting movement
🔺 Gaps forming between gear elements (e.g., sleeve/glove, pant/boot)
🔺 Compromised protection and comfort
Overall Impact on Firefighter Safety
● Greater exposure to heat, flames, and sharp objects ; ● Loss of protective performance during mission-critical moments ; ● Decreased durability, leading to more frequent replacements or unsafe use of worn gear
For optimal protection, the outer shell must not only resist ignition but also retain physical strength and stability under harsh conditions. Weaker materials can seriously undermine the effectiveness of the entire suit, no matter how strong the inner layers are. SUPER ARMOR offers a variety of shell specifications. All shells selected by SUPER ARMOR exceed the EN 469 standard requirements to protect firefighters from the above risks.
