Mobile long tube air respirators are suitable for people who work in hazardous gas production areas for long periods of time and for those who are lacking oxygen and full of toxic and harmful gases. To provide respiratory protection for emergency and disaster relief personnel in the environment, the mobile long-tube air respirator is composed of a mobile air source vehicle and an escape emergency gas cylinder. It can be used by people at the same time, and the operating area can be up to meters.
How to use long-tube air respirators and precautions:
The mobile air source consists of only one cylinder to form an independent cylinder group. The group of cylinders and the pressure reducer are controlled by a one-way valve. The gas source will not cause backflow between the gas cylinders. Cylinders can be opened and used one by one, in groups, or all at the same time, depending on specific needs. Each set of gas cylinders of the mobile long-tube air respirator has a pressure relief valve, which can release the high-pressure gas in the high-pressure pipe to facilitate the replacement of the gas cylinder, but will not release the low-pressure gas at the output end of the pressure reducer and another set of gas bottles. gas.
The mobile air source and escape gas bottle of the mobile long-tube air respirator are combined through the waist valve, and the gas from the mobile air source is directly used under normal conditions. When an emergency occurs and it is necessary to evacuate the scene quickly, you can open the escape cylinder valve and evacuate to a safe area.
The mobile air source of the mobile long-tube air respirator is equipped with a 3-meter air supply tube root and a 3-meter air supply tube root. The maximum stacked length is meters. The 3-meter pipe is equipped with a type tee, which allows individuals to use compressed air from a mobile air source at the same time.
Personnel who use long-tube respirators should be fully trained before wearing them. Before use, check whether the pressure of each air source meets the working pressure requirements, and perform strict routine wear inspections. If the respirator, mobile air source, or escape air source is found to be faulty or has hidden dangers, it shall not be forced into use. During use, if you feel insufficient air supply, difficulty breathing, or other discomfort, you should evacuate the site immediately or turn on the escape air source to evacuate.
During the use of mobile long-tube air respirators, the long tube on the mobile air source of the long-tube respirator should be properly protected to prevent the long air supply tube from coming into contact with sharp objects, corners, corrosive media or being in contact with It will rub against rough objects when dragging to prevent the air supply pipe from being punctured, scratched or scratched. If it accidentally comes into contact with corrosive media, it should be cleaned and dried with clean water immediately. If the long gas supply pipe is damaged or damaged, it should be replaced immediately.
If the air source truck of the long-tube respirator cannot follow the user at a close distance, separate monitoring personnel should be arranged to monitor the air source in order to check the air source and issue an alarm when the air source is about to be exhausted or notify the user when an accident occurs.
How to use the mobile long-tube air respirator
Take out the special waist and straps, and adjust the belt and straps appropriately according to the wearer's body shape so that the waist valve and escape bottle are positioned on both sides of the human body's waist (Pay attention to the direction of the waist valve, the quick socket should be facing upward). It is suitable to be comfortable to wear and not hinder the movement of the arms. First, insert the quick socket on the mobile air supply pipe from bottom to top to the quick plug of the waist valve, and then insert the plug of the mask-air supply valve into the quick socket of the waist valve. You can also use it without wearing a waist strap. Previously, connect the connectors between the mobile air source and the mask directly to the waist valve. Open the gas cylinder valve of the mobile air source, put on a breathing mask, and enter the work site only after you can breathe freely. If people are using it at the same time, they should wait until they are fully wearing it before entering together, and pay attention to keeping distance and direction to prevent accidents caused by mutual pulling of the air supply pipes.
