Four uses
Preparation and inspection before use
The whole set of thermal insulation clothing is composed of thermal insulation jacket, pants (or jacket and pants), thermal insulation hood, Oven glove, and thermal insulation foot shield, which should be used in a whole set. Before use, the integrity of the entire set of clothing should be checked. If it fails to meet the requirements for intact performance, it is strictly prohibited to enter the work site. The inspection content includes:
*Is there any damage, delamination, aluminum foil detachment, or open threads on the surface of the clothing;
*Whether the binding of accessories in various parts of clothing is in place, firm, and reliable;
*Whether the zipper and buttons are smooth and flexible, whether the pants straps have elasticity, and whether the fasteners are intact and reliable;
*Is the insulation head cover visible clearly.
2 Precautions for use
*Entering the work site must be equipped and fully dressed. To tighten the components of the sealing part, ensure that the clothing is well sealed.
*Firefighters should be proficient in operating and using supporting equipment correctly. For example, the wearing and use of air respirators.
*The thermal insulation hood should be worn outside the fire rescue helmet. After wearing the hood, the hood should be threaded through the armpit, adjusted for tightness, and buttoned to prevent the thermal insulation hood from falling off due to wearing activities.
*The fire protection foot cover should be placed outside the fire boots and insulated pants, covering the entire surface of the fire boots and forming a partial overlap with the insulated pants.
