What Is a Fresh Air Respirator?

It is a self-contained open air respirator. Air respirators are widely used in fire protection, chemical, marine, petroleum, smelting, warehouse, laboratory, mine and other departments. Safe and effective fire extinguishing, emergency rescue and rescue work in various environments such as lack of oxygen.

Air respirator maintenance

The air respirator and its parts should avoid direct sunlight, so as to avoid aging of rubber parts;

The respirator needs to be kept clean, and the instrument should be placed on a clean floor;

Air respirator is strictly contaminated with grease;

The temperature in the storage room should be maintained between +5 and + 30 ° C;

The rubber parts should be coated with a layer of wet stone powder if they are not used for a long time.

Air respirator precautions

(1) Wear the mask correctly and use it after inspection. The mask must be sealed. There is no hair or beard between the mask and the skin to ensure that the mask is sealed.

(2) The air supply valve should be firmly bonded to the mask according to the mouth.

(3) Pay attention to the alarm signal issued by the alarm device during use, and immediately evacuate the site after hearing the alarm signal.

How the air respirator measures pressure

1. Open the cylinder valve of the air respirator and check the pointer of the pressure gauge. The pointer should be within the green grid area.

2. Take the replacement valve in the air respirator out of the holder, and plug it into the corresponding position in the mask. If you hear a "click" inside, it means that the supply valve of the respirator is correct. Connected to the mask.

3. Take a deep breath. This breath should be rapid so that this breath can activate the breathing valve of the respirator.

4. Repeated breathing, do the above breathing 12 times, and then feel what the air flow in the breathing is.

5. Turn the red round button of the air respirator quickly, and when you open it, you will feel that the airflow in the air has a clear tendency to strengthen.

Air respirator tips

The gas supply device is equipped with a new type of gas supply valve with a small volume, light weight and stable performance; a high-quality high-pressure gas cylinder with a high strength back plate and a high safety factor is selected; a pressure reducing valve device is provided with a residual gas alarm, Within the pressure range of the cylinder, it can send an acoustic signal to the wearer.

There is a certain gap between the air respirator and the three major components of the full face mask, air supply valve and back frame. Foreign full-face masks and back frames are designed and manufactured according to ergonomic principles. The material of the sealing frame of the full-face masks is soft and tight; the back frame fits well with the back of the human body, is comfortable to carry, and is evenly stressed; air supply The air supply flow of the valve is large, and the valve is flexible.

Air respirator cleaning

The outer layer of an air-purifying respirator often accumulates a lot of dirt, bacteria and other dirt in the outside air, and the inner layer blocks exhaled bacteria and saliva. Therefore, the two sides cannot be used alternately, otherwise the dirt contaminated by the outer layer will When inhaled directly against the face, it becomes a source of infection. When not wearing the mask, it should be folded into a clean envelope, and the side that is close to the nose and mouth should be folded inward. Do not put it in your pocket or hang it around your neck.

If the air-purifying respirator gets wet with exhaled hot air or saliva, its effect of blocking germs will be greatly reduced. Therefore, it is best to prepare a few more masks in order to replace them, and they should be changed and washed once a day. When washing, first blanch with boiling water for 5 minutes.

Air-purifying respirators should be cleaned and disinfected daily. Both gauze masks and air filter masks can be disinfected by heating. The specific approach is:

1. Cleaning. Gently rub the gauze mask with warm water and soap first. The bowl-shaped mask can be gently cleaned with a soft brush dipped in detergent, and then washed with water. Please be careful not to rub hard, because if the warp and weft gap of the gauze is too large, it will lose the effect of preventing droplets.

2. Disinfection. Soak the cleaned face mask in a 2% peroxyacetic acid solution for 30 minutes or cook in boiling water for 20 minutes or steam in a steamer for 15 minutes, and then air dry for later use. This method is suitable for gauze masks and bowl masks.

3. Check. Before using it again, you should carefully check whether the masks and masks are still intact. For gauze masks and masks, you can use the light transmission inspection method, that is, take care of them before the lamp to see if there are obvious light spots, and the middle and edge parts are transparent Is the rate consistent? If in doubt, replace it with a new one. Regardless, masks and masks are generally updated after 3 to 7 times of washing, and masks of particularly good quality can be washed 10 times. Activated carbon adsorption masks should pay attention to periodically replacing the activated carbon interlayer. If the activated carbon interlayer is not replaceable, it must be replaced after 7 to 14 days. This type of mask cannot be reused after cleaning.
