The effectiveness of firefighting rescue air cushions in high-altitude rescues depends not only on the performance of the equipment itself, but also on the user's skill and on-site judgment. Mastering the key points of scientific deployment, rapid response, and meticulous attention to detail can significantly improve the success rate and safety of rescues in critical situations.
Selecting the deployment location is the primary skill. The likely fall trajectory of the trapped person should be predicted, prioritizing areas with solid, open ground and no obstacles. Sufficient horizontal distance should be maintained from buildings or the source of the fall to prevent the air cushion's edges from being impacted or the air chambers from rupturing. For multi-chamber air cushions, the main pressure-bearing surface can be positioned directly towards the predicted fall point, utilizing the distribution of air chambers to disperse the impact and improve stability.
Rapid inflation and stabilization are equally crucial. In emergencies, use a blower or gas cylinder inflation system compatible with the air cushion, and check the interfaces and pipelines for blockages beforehand to shorten inflation time. During inflation, simultaneously apply counterweights or anchor the air cushion, such as placing sandbags, securing ropes, or using vehicles to weigh down the edges, to prevent displacement of the air cushion upon impact. When winds are strong, increase the weight or lower the angle of the windward side to maintain a stable landing surface.
Coordinated command and observation can significantly improve landing accuracy. Assign a dedicated person with a walkie-talkie to maintain contact with the trapped person or rescue personnel above, confirming changes in posture and position in real time; simultaneously, set up observation posts around the air cushion, using hand gestures or light signals to indicate landing deviations, facilitating timely adjustments to the air cushion's orientation or reminding the trapped person to change their posture.
When using the air cushion, pay attention to the trapped person's landing posture. Try to guide them to land on the cushion with their feet or buttocks first, with their arms tucked in front of their chest to reduce the area of tumbling and impact. If the height of the site exceeds the air cushion's optimal cushioning range, temporarily stack air cushions or add a buffer net in front to prolong the deceleration process. After impact, quickly check the condition of the air cushion; only continue operation or reload if it is confirmed to be undamaged.
Detailed control also includes the prevention of environmental risks. Before deployment, clear away sharp objects such as gravel and glass from the ground to prevent puncturing the air cushion. Avoid direct use near high-temperature open flames; although the flame-retardant layer can slow combustion, prolonged heat radiation will weaken the material's performance. When packing up, follow the original folding instructions, avoiding heavy pressure or bending of the air chambers to maintain their shape and elasticity for future use.
The skill of using a fire rescue air cushion integrates anticipation, speed, coordination, and meticulous management. Only through repeated practice in training can one protect lives with stable, accurate, and rapid operation in real emergencies.
