Firefighting rescue air cushions play a vital role in protecting lives during critical moments, and their stable performance depends on long-term meticulous care. Scientific care not only extends their lifespan but also ensures reliable cushioning and support functions in emergencies, providing a solid guarantee for rescue efforts.
Daily storage is the first step in care.
When not in use, the air cushion should be stored in a cool, dry, and well-ventilated environment, avoiding direct sunlight and high temperatures to prevent fabric aging and coating failure. The storage location should be away from oil, chemicals, and sharp objects to prevent corrosion or scratches to the fabric. When folding and storing, follow the manufacturer's recommendations, avoiding excessive bending or heavy pressure to prevent deformation of the air chamber structure or damage to the seams. Large air cushions can be hung or laid flat on a dedicated rack to maintain their shape.
Pre-use inspection is essential. Check the air cushion surface for obvious wear, cracks, bulges, or localized hardening, and confirm that the seams and heat-sealed areas are secure and leak-free. For multi-chamber structures, the sealing of each valve and connector must be checked individually. If necessary, an inflation test should be conducted to observe pressure maintenance. If a rapid drop in air pressure or abnormal collapse of a chamber is observed, use should be suspended, the cause investigated, and components repaired or replaced promptly.
Protection during use is equally important. Before deployment, clear away sharp objects such as gravel, glass, and metal shavings from the ground, and establish a warning zone around the air cushion to prevent unauthorized personnel from stepping on or colliding with it. After inflation, double-check that the fixing buckles or counterweights are secure to prevent displacement of the air cushion upon impact. Avoid direct contact with open flames or high-temperature fumes during use. Although the flame-retardant layer can delay combustion, prolonged high temperatures will still damage the material's properties.
Post-use cleaning and maintenance should be performed promptly. Wipe surface stains with a clean, damp cloth. Do not use strong acids, strong alkalis, or organic solvents for cleaning, as these may damage the fibers and coating. For oil stains, gently wipe with a neutral detergent, then wipe clean with water and allow to air dry. Drying should be done naturally in a cool, shaded place; avoid direct sunlight or tumble drying to prevent material shrinkage and deformation. Maintenance records must detail the number of uses, inspection findings, and corrective actions taken to provide a basis for subsequent maintenance.
Periodic maintenance can be incorporated into the equipment management system. It is recommended to conduct comprehensive sealing and pressure resistance retests at regular intervals, and assess the replacement cycle based on usage frequency and storage environment. For air cushions on long-term standby, regular inflation maintenance should be performed to maintain air chamber tension and prevent the material from losing elasticity over time.
The care of fire rescue air cushions involves all aspects of storage, inspection, use, cleaning, and regular maintenance. Only through strict adherence and meticulous attention to detail can this life-saving equipment remain reliable and fulfill its mission in times of crisis.
