Is there a limit to the length of the trachea that can be used for a long tube respirator?

It is generally recommended that the length of the air duct of the self-priming long tube respirator should not exceed 20 meters, and there is no requirement for the air supply respirator. Because the human body needs to breathe with a long tube to introduce fresh air, a long tube respirator is used.

It is necessary to pay attention to the length of the long tube, that is, the working radius. Self-priming long-tube respirators are used, and the length of the long tube should not exceed 20 meters due to the limitation of the self-priming force of the lungs. The electric blower is electric, the air supply can be seen that the air guide pipe is extended to more than 100 meters, no problem, the greater the horsepower of the electric blower, the greater the output of the electric blower, and the working area will be relatively large.

There are three other things to note:

1. The gas mask cannot be taken off when using a long-tube respirator in a toxic environment.

2. Filtering gas masks cannot be used in a high-concentration confined environment.

3. Replenish the long tube of the long-tube respirator in time, or equip it with a spare airway tube to prevent the limited working radius and inability to cope with unexpected tasks. In conclusion, we must pay attention to the length of the long tube when using a long tube respirator.

You can try the long-tube respirator of OMBA because it belongs to medium-pressure transportation, so the length can reach the national standard of 80 meters, (it can also be used within 120 meters, but the national standard requires only 80 meters).

Moreover, OMBA is an explosion-proof equipment, which can be used in chemical plants, flammable and explosive occasions.

The main points of using a long-tube respirator in general are:

1. Select the appropriate mask, which is closely connected to the air duct, and the air inlet is placed in the upwind and fresh air of the operation.

2. Check the breathing valve and suction valve, and carry out the air tightness test, so as to "wear first and then enter".

3. The trachea should be smooth, straight and unblocked, and it is strictly forbidden to step, squeeze, entangle, and force pull when using.

4. Assign special personnel to monitor and inspect the air intake of operators and trachea.

5. If you feel difficult to breathe or feel unwell during the operation, leave the poisoned area immediately.

6. Carefully inspect before use, inspect, clean and keep properly after use.

Users of long-tube respirators should be fully trained before wearing them. Before use, it should be checked whether the pressure of each air source meets the requirements of working pressure, and strictly routine wear inspection, and if it is found that the respirator, mobile air source, and escape air source are faulty or have hidden dangers, they shall not be forced to be put into use.

During use, if you feel that the air supply is insufficient, the breathing is not smooth, or other discomfort occurs, you should immediately withdraw from the scene, or open the escape source to evacuate.

During the use of the long tube respirator, the long tube on the mobile air source of the long tube respirator should be properly protected, so as to avoid contact between the long tube and sharp sharp instruments, angles, corrosive media, or friction with rough objects when dragging, so as to prevent puncture, scratching, and scratching of the air supply tube. If you accidentally come into contact with corrosive media, you should immediately clean and dry it with clean water, and replace it immediately after damage or damage to the long gas supply pipe.

Vehicle-mounted positive pressure long-tube air respirator (hereinafter referred to as respirator) is a kind of respiratory protection device that is safe and reliable, easy to use and maintain, and can be used for a long time, the respirator can replace any gas cylinder in the work without affecting its use, and can work continuously, if it is specially needed, it can also be connected with a small compressor or other air sources for use, and it can also provide a special protection type double pressure reducer for special environmental use.

Due to the compact structure and simple operation of the respirator (push structure), the user does not need to carry heavy items such as gas cylinders and backpacks to work, and it has the characteristics of lightness and flexibility. It is especially suitable for narrow occasions, toxic and harmful gas oxygen places to do long-term maintenance, inspection, cleaning, painting and smelting work, such as: oil tanks, machine warehouses, underground pipelines, gas pipelines and other places.

Generally, it is commonly used in petrochemical industry, aerospace industry, underground mining, nuclear plants, chemical plants, paint industry, gold industry, fire protection industry, etc.

The open-circuit medium-pressure air breathing apparatus (OMBA) launched by Tianjin Sanshengjiu and Safety Service Technology **** is a mobile air supply equipment. It is enough to ensure the normal operation of cleaning operators in a highly toxic and high-risk environment.

It can be used in various confined spaces and toxic and harmful high-risk working environments, which can meet the needs of multiple people to work at the same time for a long time, and is flexible and lightweight, which is more convenient for workers.

OMBA open-circuit medium-pressure long-tube respirator conforms to the national standard GB6220-2009 "Respiratory Protection - Long-tube Respirator".

First of all, before using the self-priming long tube respirator, we need to ensure that all parts are intact to ensure its normal use. It is necessary to check whether the parts are intact and clean, whether the trachea pipe is cracked, bubbled, flattened, bent, and leaked, and whether the connection parts are firm. If any abnormalities are found, they should be repaired or replaced with new ones in time.

Whether the air tightness of the self-priming long tube respirator mask is good is directly related to the safety of human breathing, and testing the air tightness of the mask is also an important preparation before the use of the self-priming long tube respirator. Perform a positive pressure test before putting on the mask Wear the mask and press the back of your palm against the breathing valve cover to make it completely airtight. Exhale increases the pressure inside the mask, and if the mask is leaking, the pressure inside the mask is not felt, and the band should be adjusted to fit the mask against the face, or the suction valve should be checked to see if it is normal.

When you're wearing your mask, take deep breaths to see if you're breathing well. The trachea can be fastened to the waist with ropes and the like, and it is checked that it is free to move.

If there is no abnormality in the above inspection preparations, the operator can wear a long-tube respirator into the operation area.

The main purpose of the OMBA open-circuit long-tube respirator is to check the test operation effect of the equipment, check whether there is a pressure display after starting, check the normal display of various combustible benzene H2S, etc., and then check the air pressure of the mask. The process is fast, but safety comes first, and it is best to be careful.

First, the mask of the long tube respirator should be checked, and then the gas cylinder should be checked, and whether the parts are normal TDAF001
