Fire air call is an important equipment for firefighters in the process of fire fighting and rescue, it can provide firefighters with fresh air and protect them from toxic and harmful gases. However, to ensure the normal operation and effective use of fire air calls, some precautions for use and maintenance must be observed. This article will detail the use and maintenance of fire air calls to ensure that firefighters can safely and effectively use this equipment in emergency situations.

First, use precautions

Check before use

A thorough inspection must be carried out before the fire air call is used. First of all, make sure that the pressure in the cylinder is sufficient to ensure sufficient use time. Second, check that the mask is intact and has no damage or scratches to ensure its sealing performance. At the same time, it is necessary to check whether key components such as breathing tubes and pressure reducing valves work normally. Any damage or malfunction should be repaired or replaced immediately.

Wear and use correctly

When wearing a fire air call, ensure that the mask is tightly fitted to the face to prevent the infiltration of toxic gases. Adjust the headband to ensure stability and comfort. During use, firefighters should pay attention to breathing rate and depth to avoid excessive consumption of air in the cylinder. At the same time, always pay attention to the air supply to ensure that there is enough time to evacuate in an emergency.

Compliance with operating procedures

Firemen should strictly abide by the operation rules when using fire air call. Do not use empty call for a long time when it is not necessary to save the air in the cylinder. In addition, when using the air call, to avoid strenuous activities, so as not to increase the respiratory burden and consume more air.

Two, maintenance precautions

Wash and disinfect regularly

The masks, breathing tubes and other parts of the fire air call will be exposed to a lot of dust, smoke and other pollutants during use, so they must be cleaned and disinfected regularly. When cleaning, use a mild detergent and a soft cloth to wipe and avoid harsh chemicals. When disinfecting, ultraviolet disinfection or special disinfectants can be used to ensure that bacteria and viruses are completely killed.

Regular inspection and maintenance

In addition to daily cleaning and disinfection, it is also necessary to carry out regular comprehensive inspection and maintenance of the air exhaust. This includes checking the performance of key components such as cylinder pressure, pressure reducing valves, and filtration devices. Once a problem or fault is found, it should be repaired or replaced immediately. In addition, regularly replace the wearing parts, such as filters, gaskets, etc., to ensure the normal operation of the air call.

Proper storage and safekeeping

When the fire air call is not used, it should be properly stored in a dry, ventilated and cool place. Avoid direct sunlight and high temperature environments to avoid affecting cylinder performance and component life. At the same time, ensure that the storage environment is away from fire sources and flammable materials to prevent accidents. When stored, the mask should be placed upward to avoid compression and deformation.

Training and awareness raising

In order to ensure that firefighters can properly use and maintain fire air calls, regular training and drills must be conducted. The training content should include the structure of the air call, the use of methods, maintenance points and emergency response measures. Through training and exercise, improve the safety awareness and operation skills of firefighters to ensure that fire air calls can be used quickly and accurately in actual combat.

In short, as an important equipment for firefighters, fire air call plays a key role in ensuring life safety and improving fire rescue efficiency. In order to ensure its normal operation and effective use, we must strictly follow the precautions for use and maintenance. Through strengthening training, improving safety awareness, regular maintenance and inspection and other measures to ensure that the fire air call is always in good working condition, to provide strong support for fire fighting and rescue work.
