2. Breaking strength of the seams of the outer layer of the insulation suit: ≥780 N;

Specifications, Dimensions, Weight

1. Specifications (Note: Special specifications are agreed upon by both parties)

2. Weight: The complete insulation suit weighs 5760g (including backpack).

Usage

1. Preparation and inspection before use

The complete insulation suit consists of an insulation jacket, pants (or a combined jacket and pants), insulation hood, insulation gloves, and insulation foot covers, and should be used as a complete set. Before use, the integrity of the entire suit should be checked, and it is strictly prohibited to enter the work site if the integrity requirements are not met. The inspection items include:

Whether the surface of the clothing has any damage, delamination, aluminum foil falling off, or loose threads;

Whether the accessories of each part of the clothing are properly fastened, firm, and reliable;

Whether the zippers and buttons are smooth and flexible, whether the pants suspenders have elasticity, and whether the Velcro is intact and reliable; whether the view panel of the insulation hood is clear.

2. Precautions for use

When entering the work site, it is necessary to be fully equipped and dressed, and to fasten the sealing parts tightly to ensure good sealing of the clothing;

Firefighters should be proficient in operating and correctly using the equipped gear, such as wearing and using air respirators;

The insulation hood should be worn outside the firefighter rescue helmet, and after putting on the hood, the hood strap should be passed under the armpit, adjusted for tightness, and fastened to ensure that the insulation hood does not fall off due to movement.

The insulation foot covers should be worn over the firefighter boots and insulation pants, covering the entire boot surface and overlapping with the insulation pants.

Maintenance and Care

If the thermal insulation suit is dirty after use, it should be cleaned. When cleaning, use a soft brush dipped in neutral detergent to scrub the surface and remove residual dirt, then rinse thoroughly with clean water. Hang it in a ventilated area to air dry naturally. It is strictly prohibited to soak in water or hit it, and baking during drying is also strictly prohibited.

1. The clothing should be inspected after use, and any issues should be repaired in a timely manner;

2. If it cannot be repaired or if the repair affects the overall protective performance, it must not be used on the job site;

3. The repaired thermal insulation suit should be inspected by personnel, and only after passing the inspection can it be stored, and it should be marked in a prominent position on the clothing;

Storage

1. The packaging of the thermal insulation suit is in a bag style, with one set of clothing per package. It must not be opened and exposed. It can be stored in its original factory condition in a box on a shelf 20cm above the ground to prevent moisture and dirt;

2. The thermal insulation suit should be stored in a warehouse. Depending on the warehouse conditions, it should be ventilated and rearranged regularly, and if necessary, it should be aired out to prevent issues such as aluminum foil falling off, delamination, mold, and insect damage due to moisture;

3. An unpacking inspection should be conducted every three months to check if the clothing has been damaged due to storage reasons;

4. During storage and movement, avoid contact with hard or sharp objects to prevent scratches and damage.

5. Storage period: two years.

Special Warning

Although the fireproof thermal insulation suit has excellent flame retardant and thermal insulation properties, it does not provide protection under all conditions:

1. When working near flames, do not allow direct contact with flames or molten metal!

2. It must not be worn or used in environments with chemical hazards, toxic gases, viruses, or nuclear radiation!
