/Positive pressure self-contained air breathing apparatus is an inspection of air-wearing devices. We will not go into this. You can understand it at a glance. The basic requirement is to be fixed on the body and facilitate body activities. The next step is to check the pressure of the gas cylinder. I won’t talk about the pressure drop within minutes. There is not that much time to wait, but it is still necessary to check the pressure. The normal pressure is % of the standard pressure of the gas cylinder. For most The gas cylinders used by the unit are too simple for everyone. Let’s take a look at the inspection of the alarm valve. We will talk about this in detail. Many people ignore its inspection. I believe everyone understands that this thing is for us to wear a positive pressure air respirator. The final guarantee for entering dangerous places after the operation is completed. Sorry, I forgot another detail. Didn’t you check the air tightness after putting on the mask? Why do you need to check it twice? The first time is to check the functional integrity of the mask, and the second time is to check the correctness of wearing.
/ Precautions when using positive pressure self-contained air breathing apparatus. Firefighters with respiratory diseases are not allowed to perform tasks that require breathing apparatus.
.Isolation respirators should not be used immediately after taking on a job with high labor intensitybr/>. For jobs that require respirators, two should accompany each other to take care of each other.
. During use, the wearer should observe the indicated value of the pressure gauge at any time, and evacuate the disaster area in time according to the distance and time to evacuate to a safe place, or evacuate the disaster area in time after hearing the alarm signal from the alarm.
.Once entering an air polluted area, the respirator should not be removed until after leaving the polluted area. Colleagues should also be careful not to mistakenly remove the respirator because visibility has improved, assuming that the area is no longer polluted.
.When opening the gas cylinder valve, in order to ensure sufficient air supply, the valve must be unscrewed more than a circle, or fully opened.
During the use of gas cylinders, avoid collisions, scratches, and knocks, as well as high-temperature baking, high-temperature freezing, and sunlight exposure. Paint peeling should be repaired in time to prevent the bottle wall from rusting. If serious corrosion or damage is found during use, use should be stopped immediately, inspected in advance, and used only after passing the inspection. The service life of ultra-high-strength steel air cylinders is years.
.The air in the cylinder cannot be completely used up, and a residual air of no less than . It is spacious, has good optical performance, double folded edge sealing, mesh headband, and equipped spare interface for connecting communication and audible and visual alarm devices.
The air supply valve is a positive pressure air supply with a small appearance. It is equipped with a shut-off switch and a manual bypass valve. It automatically opens by inhaling. As much as you inhale, the air supply volume is sufficient. This air supply valve is connected to On the side of the mask, it can prevent the impact of falling objects and has high safety and reliability.
The output pressure of the pressure reducer is self-adjusting and balancing, and it has automatic overpressure protection. It has a compact structure and is equipped with multiple spare interfaces to facilitate upgrades and improvements, such as upgrading double bottles, connecting other rescue connectors, audible and visual alarm devices, and cleaning blowers. Washing device, connecting long pipe air supply source, etc.
The pressure gauge and alarm whistle are integrated and are placed on the user's chest for easy observation and identification. The pressure gauge has a shock-proof protective cover. There is fluorescence on the dial, and the pressure value can be viewed in the dark
Back The board is made of high-strength nylon injection molding, and the ventilation pipes are embedded on the inside of the back panel to prevent scratches. It is universal for various specifications of gas cylinders. Different types of cushions can also be installed on the back panel, such as semi-soft cushions, full cushions, etc. Suitable for different users, making the wearer more comfortable.
The gas cylinder is a carbon fiber composite gas cylinder with specifications of., etc., and the working pressure is.
All connectors on the pipeline can rotate freely, which is suitable for a variety of occasions where the user needs to replace the gas bottle and wear it with bare hands without any auxiliary tools, making the operation simple and convenient.
