It knows that when working in hazardous and dusty environments, we must take reasonable precautions. If you must work in an environment with a lot of sawdust and wood dust, it is necessary to equip the best woodworking dust masks to ensure the health of workers. However, many people still do not know how to use and clean covers to preserve them.
Structure and operating principle of the dust mask for woodworking
Most workers using a gas mask, neglecting the critical step, which finds out the frame of products. If the employee works in an environment with low-level chemicals, less exposure time, you only need to search for a suitable one-filter dust mask. Also, you can use a cover that has two filters to protect better health. It leads to workers to choose the wrong type of respirator with their working environment causing respiratory diseases when used or causing waste.
- Structure of the woodworking dust masks
Currently, on the market, there are many types of high-quality protective covers being born, meeting high-quality standards. That helps workers and engineers have more choices for themselves. But in general, the material of the respirator mask is made of two main types: Polycarbonate, Silicon.
The filter of gas mask:
The screen is considered to be the “soul” of the gas mask. Because this component contains activated carbon, occupying one of the essential tasks is to remove dirty air, which can cause discomfort and the shortness of breath for the users when inhaled.
If a worker works in a chemical industry workshop with a high concentration of dirt, lots of toxic gases, you need to use the gas masks equipped with two filters. Because of this, the new screen works well to protect maximum safety for your safety.
- The working principle of the gas mask
Artificial respirators use a combination of a filter cartridge (filter) to remove gases, volatile organic compounds (VOCs), and other vapors from the air by adsorption and adsorption. A typical respirator filter is a metal or plastic container containing 25-40 grams of adsorbed particles such as activated carbon or certain resins. The life of a chemical filter varies based on other parameters, according to the carbon weight and molecular weight of the vapor and the transfer parameters, the concentration of water vapor in the air, the relative humidity of the sky, and respiration of respirator user. When the filter becomes saturated, or particles accumulate in it begins to restrict airflow, we have to change to a new filter battery. If concentrations of hazardous gases are immediately dangerous to life or health, the law requires that the use of any air purifier strictly monitor.
The purpose of the woodworking dust mask is to let the air be polluted or a variety of pollutants, remove a sufficient amount of these contaminants and then supply the air to the user. Use different filters for different working environments — the amount of air reaching the user through one or more screens for the user to breathe.
Instructions on how to use the mask correctly and how to store it
- Instructions for using the cover properly
The respirator has two types of breathing valves: the valve that directs the air into the filter and the exhaust valve flows as a transport in a closed cycle. In case the air intake valve is open, toxic gas will enter the pipes, following the flow into the lungs in the nasal period. In the case of open exhaust valves, exhaled air, and tiny particles of water and when the carbon will attach to the filter material such as activated carbon. It is a fast corrosive material; the filtering function significantly reduce. Should choose the type of gas masks with valves to open quickly, durable, ensure tightness.
The filter is quickly saturated. Therefore, it must be replaced periodically depending on the type, storage conditions, time of contact with chemicals, use time, the density of chemicals, and toxic properties of compounds.
Just like the daily farm work, while spraying pesticides, when a little smell the smell of drugs while still wearing a mask, they must change immediately. Please refer to the table of instructions for using the respirator mask of the filter you buy to know precisely when to replace.
Activated carbon is the main ingredient in the filtration process. After that, it reinforces with appropriate chemicals depending on the environment of use; the toxins need to be filtered and can add a catalyst to coal. Active can absorb toxic gas. The filter has a pore, cavity structure to keep toxic vapors in contact with activated carbon. Next will appear the chemical reaction process in the screen; the impregnated chemicals convert poisonous gas into the fresh air. Clean air flows through the valves into your nose. Sometimes, to ensure adequate air supply, the filter also contains additional catalysts to make the process faster, more active than usual. So when the filter box has saturated, expired, cracked, dust making the breathing process difficult, they need to be replaced immediately.
- Time to use the gas mask
Time to use respirator masks on average from 1-2 hours. It is time to ensure the cover works best.
The duration of use also stated in the Respirator Instruction Manual is intended for environments with a unique level of toxicity, as well as environments with high concentrations of toxic gases, high pressures, temperatures and humidity, and service life. The filter significantly reduces. The preservation and maintenance regime after use is also related to the service life of the filter box. In the same working position, the higher the amount of breathing air the person has, the shorter the filter’s life will be. When the screen opens, it will be discarded for a long time because the activated carbon no longer works.
- How to store respirators:
For the gas mask to be durable and safe during use, users must know how to preserve it best. When choosing a gas mask, it should select the type of valve that opens easily, durable, ensuring tight. Due to the different working environments, depending on the type of cover will fit or not. If exposed to dense gases, heat, pressure, and humidity will cause the mask to degrade quickly.
Therefore, users should pay attention to maintenance masks regularly. Check to see if there are signs of cracking, difficulty breathing, or smell of chemicals; you need to change the cover urgently. Attention should be paid to the air passage; avoiding leakage will be very dangerous.
Besides, immediately after using the 3M respirator, inspect the filter. If it finds that the contact environment has a lot of harmful reading gases, the filter must be replaced immediately to ensure life. At the same time, each screen has its expiry date, so be careful to replace it.
The woodworking dust masks are a particular product to help avoid the harmful effects of toxic gas, so you need to pay attention to the structure and operation of the gas mask. Once you know the function of the parts, you will have more experience in buying the right cover for your needs.
