Respirator for painting cars: why is it necessary and how to choose?
31/12/2018 | ARPSHOP
In painting works, not only painting tools are used, but also various protective equipment. A painting respirators protects the respiratory organs during repair. Protecting the respiratory system is important not only during work with spraying, but also during any repair.
Devices for working with paint must be chosen correctly. Paints and clear coat, regardless of the type and composition, are highly toxic. Painting cars, usually occurs in a specialized chamber or in the garage, where there is no proper ventilation. Accordingly, harmful toxin vapors accumulate and concentrate. Couples can lead to acute intoxication of the body and seriously harm health. The result is nausea, dizziness and the risk of loss of consciousness. In severe cases of poisoning and suffocation are observed. To prevent such dangerous situations for human life and health, there are labor safety rules developed by the labor protection institute. To ensure safety, it is enough to wear a respirator to paint the car, and which one depends on the amount of work and the individual toxicity of paintwork materials.
Exposure toxins and effects.
Car painting is carried out using spray guns spraying oil paints, primers and fixers. In other cases, powder paint with a spray gun is used for painting. A common feature of both devices is spraying. In addition to the concentration of vapor, microparticles of paintwork material hang in the air in the room. Getting into the lungs of a person through the respiratory tract, particles of paint are deposited on the surface and poison the body from the inside. The consequences of such intoxication can manifest themselves for a long time and in a more acute form. Often they require immediate medical intervention, as they can provoke respiratory diseases.
What gets to the paint in the body?
- toluene and xylol;
- carbon disulfide;
When these substances enter the human body, oxygen starvation occurs. As a result, the functioning of internal organs is disturbed: liver dysfunction, heart rhythm disturbance, stopping of the stomach. Especially critical is the lack of oxygen for the central nervous system. Mental disorders associated with oxygen starvation are most pronounced in acute poisoning with toxic substances:
- disorientation in space;
- dullness of the organs of charm and loss of taste;
- loss of sensation time;
- panic attack.
Mental manifestations of intoxication are followed by physical ones that cause acute excruciating pains and can last for some time after rendering assistance to the victim. Most often manifest:
- blood wear;
- pains in the joints and soft tissues;
Types of paint respirators
To avoid all the unpleasant consequences of painting work, you can adhere to safety rules. You must wear a respirator mask to paint the car, even if the front of the work is not significant. 5 minutes indoors, where fine paint is sprayed enough to poison the body. It is important that the best respirator is selected taking into account the size of the face and advises the potential load on the respirator filter element.
Conditionally share two types of safety respirators:
The work of a filter type respirator is based on the formation and retention of an air cushion. Inside the mask there is a filter that retains and absorbs air. After cleared flow enters the respiratory tract. As a rule, a cotton wool layer or a carbon respirator cartridge acts as a filter. The carbon filter is a reliable absorbent against the small fraction of paint stuck in the air, as well as debris. But such a filter is helpless against chemical fumes, especially isocyanate. It is this substance that is released when the paint dries, kneads, or coats with a fixative. For such cases, an insulating respirator is provided. The main difference between this personal protective equipment is that it protects the airways from the external environment. Before painting the car must purchase a respirator. Its quality depends on the price. The latter is formed due to the characteristics of production. All protections are labeled, which determines the ability of the mask to protect the airways from more harmful vapors and toxins. Marking and its interpretation should be indicated in the accompanying certificate of authenticity.
Therefore, it is necessary to clearly know the scope of work and the possible toxicity of painting a car to select a suitable n95 respirator. The respirator is used not only for various painting works on various surfaces, but also for all types of repairs, since they protect the respiratory system from odor, dust and small parts of paints and clear coats.
Respiratory painting devices may be used once or several times. If you use the reusable option, then after each use you need to change the filter. Before use, the inner side should always be disinfected and periodically during operation will remove moisture. Classification Devices for protection have a simple structure and are divided into several groups: half-masks respirator; on the whole face; for the whole person with forced oxygen supply; all over the face with a special breathing apparatus in which high pressure is maintained.
If we talk about technical requirements, then there are two groups: Filtering. You can breathe air that is cleaned through the filters. Insulating. Oxygen is contained in the fixture itself. Air can be supplied through a hose or through a separate breathing apparatus.
When choosing protective equipment, one should pay attention to their main advantages: low weight, so the body will not be loaded; low resistance during the respiratory process; quite a long time, during which you can use masks. If you have to work with paints that contain a lot of toxins, it will be difficult for the respirator to protect the respiratory organs from odors, since toxins are absorbed even through the skin. In such cases, you need a full protective suit.
Rules for the selection of protective equipment
When choosing a protective device you need to consider a few points to protect the respiratory organs.
If the concentration of paint is normal, but the smell is strong, then we need at least the most simple filters that are made of fine-fibrous materials, polymers. These masks cost a bit, but they protect the body from toxic fumes. Rules for the selection of protective equipment When choosing a protective device you need to consider a few points to protect the respiratory organs: Conditions in which protection must be used. Paint concentration Condition dyes.
Protection must be made of high quality, non-allergenic materials. Air filtration should be very good. Painting respirators are a safe process for painting any surface without harm to health. Using a face shield is a safety requirement. Applying high-quality protective agent during painting, you will save yourself from possible complications.
