GB/T 39098-2020 in English

This standard is equivalent to ISO 22488:2011, which is applicable to personal protective equipment used by ship firefighters when fighting small and medium-sized fires. It clearly stipulates the following key technical requirements for protective clothing, gloves, boots and helmets:

1. Flame retardant performance

All equipment must pass ISO 15025 procedure A test: Afterflame and smoldering time are both ≤2 seconds, and no dripping is allowed The outer material of the protective clothing must still meet the requirements after 50 washes.

2. Thermal protection performance

When using the ISO 6942 radiant heat test (40kW/m²): RHTI24 of protective clothing ≥18 seconds, RHTI24 of boots ≥35 seconds. The flame conduction test (80kW/m²) requires HTI24 ≥13 seconds.

3. Structural integrity

• Tensile strength of protective clothing seams ≥20N (≥16N after 180℃ heat treatment)
• Helmet visor must pass 1.3m steel ball impact test (Appendix E)
• Boot zipper lateral load ≥370N

Protective clothing

Must be equipped with retro-reflective/fluorescent material with a width of ≥50mm (Appendix A), and the overlap between the split protective clothing and the boots is ≥300mm.

Fire helmet

The cape material must meet the same thermal protection requirements as the protective clothing, with a total mass ≤1.5kg and a visor viewing angle range ≥60° (Appendix F).

Overall compatibility

The total weight of the full set of equipment (including respirator) is ≤7kg, the wearing time is ≤60 seconds, and the increase in the mobility test time is ≤1.5 times (Appendix G).

1. Prefer inherently flame-resistant materials to improve durability
2. Regularly check the cracks on the boot sole (＞10mm×3mm need to be replaced) and the transparency of the helmet face screen
3. The arrangement of reflective materials must comply with the 360° visibility requirements of Appendix A
4. The storage environment should avoid long-term direct ultraviolet rays (refer to 5.4.3 UV test)
