Noise hazards exist in many operating environments.In this regard, workers need to use personal protective equipment to avoid or reduce the noise to the human body, protect the ear from excessive stimulation. So what personal protection equipment can we use to protect our ears from noise? 1, Ear plugs Earplugs are generally made of soft rubber (neoprene), soft plastic (POLYvinyl chloride resin), foamed plastic and silicone rubber and other materials. The shape of earplugs is mainly cylindrical and umbrella-shaped, and the common models are large, medium and small.To medium, high frequency noise has a better sound insulation effect, contrary to low frequency noise sound insulation effect is poor. In addition, earplugs have the advantages of cheap, durable, compact, easy to carry and so on.However, it should be noted that the ear canal varies from person to person, so it is generally difficult to buy an earplug that completely fits the ear canal.Therefore, wearing inappropriate earplugs for a long time can make the ears uncomfortably, and even cause ear distention and ear canal pain. 2. Sound proof cotton Sound proof cotton is a kind of ultrafine glass wool with diameter of 1~3 m, which is softened by chemical softening.To use, just tear off a piece with your hands, roll it into a cone and place it in your ear.The sound insulation effect of anti-sound cotton is better than that of ordinary cotton, and has better sound insulation effect on high-frequency noise.Therefore, anti-sound cotton is generally used in workshops where there is high frequency noise, but dialogue is required. 3, earmuffs The structure of the earmuffs is: housing (made of hard plastic, hard rubber and metal plate)+ sealing washer (made of multi-brush soft foam and outer color POLYvinyl chloride film)+ rack + lining sound absorbing material. The average earmuff volume is 15~25dB.It is mainly applied to the air dynamic noise generated by dynamic machinery, such as strong gun pulse noise, aviation engine noise, rock drill noise and internal combustion engine noise, as well as various pneumatic tools, riveting welding, stamping, cold working and other mechanical noise working environment. Compared with earplugs, earmuffs are relatively large in size and inconvenient to wear. Especially when working in high temperature environment, wearers are more likely to feel hot and uncomfortable. 4. Sound helmet Sound helmets are generally divided into two types: soft noise helmet and hard helmet.Among them, the soft anti-noise cap is mainly composed of artificial leather and earmuffs, and its main functions are sound insulation, shockproof, trauma and cold protection.The hard helmet is composed of a shell (made of fiberglass), a lining of sound absorbing material, and an ear cover, which can prevent the noise from passing through the air conduction and the skull to the inner ear, and reduce or avoid the damage caused by shock wave to the hearing and the head.The weight of helmet is relatively large, so it is easy to appear uncomfortable symptoms such as sultry, sweating, dizziness and dizziness when worn under high temperature environment. 5. Protective clothing The protective clothing is made of glass steel or aluminum plate and lined with soft porous sound absorbent material, which is generally used to prevent the damage of high intensity noise above 14dB to human internal organs. Noise is very common in our life.However, ppe is not required in every situation.In general, people living in high noise environment for a long time are advised to use personal protection products to avoid noise damage to the ear, which can lead to other diseases.So, I hope that the above share, to help you.

Labor Protection Products Tips : N95 Mask Common Problems Masks are often used both in daily life and at work.Because the range of use is very wide, so the classification of masks is more.Because of this, in daily life, many people often choose the wrong mask. In this regard, Yang Yue suggests that before you buy or use a mask, you should have some understanding of the mask, so that it is convenient for you to choose, and you can know whether you choose the wrong mask. Today, Yang Yue for you to share a simple, one of the masks N95 masks, I hope to help you. 1. What is an N95 mask? According to Baidu Baike, the N95 mask is a NIOSH certified respirator against particulate matter."N" refers to a regrettable condition not suitable for oily products, and "95" refers to a filtering efficiency of more than 95% under NIOSH standards.N95 masks do not refer to any one product, but a product that meets the N95 standard and is approved by NIOSH to be called an N95 mask. 2. Is N95 mask a disposable mask? N95 masks are not disposable masks and can be used multiple times.However, every time you clean it, it will reduce the dust protection effect of the mask, and when cleaning, do not rub vigorously.If it is after several times of cleaning, it is recommended to change the mask, so as to better respiratory protection. 3.How should N95 masks be worn? First, loosen the band of the mask every 2~4cm. Secondly, put on a mask and keep it close to your face. Put the fixed belt on the top of your head and the back of your head respectively. Then, press the metal strip on the side of the mask to make it fit your face; Finally, check the tightness of the N95 mask and adjust it to the most comfortable state. 4. How long can the N95 mask last? Because everyone's usage and environment are different, the usage time cannot be generalized.But it's safe to say that it should be removed as soon as you find difficulty breathing or discomfort during use. 5. Under what circumstances should N95 masks be replaced? If any of the following occurs during use, the mask should be replaced immediately: 1. The mask is infected by blood, droplets and other foreign bodies; 2. Feel difficulty in breathing or discomfort; 3. The mask is damaged. 6. Do all people wear N95 masks? Not all people are suitable to wear N95 masks, if there are the following questions, it is not appropriate to wear N95 masks: 1. Patients with respiratory diseases such as asthma and emphysema; 2. Pregnant women; 3. People who feel uncomfortable after wearing it, such as those who have difficulty breathing or feel dizzy. In fact, the mask is one of the labor protection products, to the human respiratory protection.Therefore, we should learn about masks, so as to correctly choose and use masks suitable for ourselves.

How Should People Continue to Prevent and Control COVID-19 When it is Still Serious ? On 19 June 2020, months have passed since the outbreak of COVID-19 in China.However, the global COVID-19 epidemic is still not optimistic.To date, the number of confirmed coVID-19 cases worldwide has reached more than 8.5 million and the number of deaths has reached more than 450,000. In China, coVID-19 has gradually been brought under control despite the government's repeated macro-control measures.However, the recent cases of coVID-19 and asymptomatic infections in Beijing suggest that China is still at risk. Therefore, we hope that the people will continue to do a good job in self-protection and reduce the pressure of the country on epidemic prevention and control.I hope the following prevention and control Suggestions will be helpful to you. 1. Continue to pay attention to relevant information released by government departments to understand the activity track of confirmed cases and asymptomatic infected persons.If the trajectory is associated with the activities of the reported cases, or recently have been to some areas prone to disease (such as the recent Beijing xinfadi wholesale market, etc.), or contact with high incidence relevant personage, should contact the community staff, accompanied by related personnel, to the designated agencies for nucleic acid and antibody screening.Do not hide the relevant itinerary, track and other information, so as to avoid more serious consequences. 2. Do not go to areas with high coVID-19 incidence (such as recent Beijing) unless necessary.If necessary, please take good personal protection.If you wear disposable medical masks or N95 masks, try to avoid places where groups gather. 3. Keep a sense of personal protection at all times, wear a mask scientifically, keep a safe social distance, and avoid gatherings.Wash hands frequently, ventilate frequently, and eat healthily indoors. 4. When you go out to buy food, especially fresh meat, you should avoid direct contact with fresh meat. It is recommended to use gloves or bags for selection, and place them separately to avoid contact with other fruits, vegetables or cooked food.After buying, should deal with food separately in time, and wash hands with disinfectant.When cooking, chopping board, guessing and cutlery should be hidden to separate raw and cooked and timely cleaning disinfection.Wash hands promptly after handling raw meat.When cooking food, try to cook it well. Do not eat raw or cold food. 5. In case of fever, cough and other symptoms, in order to protect the safety of yourself and your family, you should timely report to the community, and then go to the designated fever clinic for treatment, so as to avoid delayed diagnosis and spread.In addition, you should wear a mask at all times and avoid taking public transportation to avoid infecting others. 6. If you have other problems, you should call the local DISEASE control and prevention center for timely consultation. The coVID-19 epidemic is not over yet, so we hope that the people should maintain adequate awareness of protection to ensure that they and their families can live healthier lives.Hope above a few Suggestions, be helpful to everybody.

How to do Personal Protection in COVID-19 (Hand Washing) Faced with the novel Coronavirus epidemic with ups and downs, what should we do in daily life to do a good job of personal protection? In fact, if you want to do a good job in personal protection against coVID-19, you can start with hand washing, masks, living environment and your own health. So, Guangzhou Yang Yue security according to the relevant authorities released the information, and the observation of the actual situation, for everyone to summarize the hand washing, masks and other pieces, I hope to help you do a good job of personal protection work. The First -- Hand Washing: 1. Why wash your hands? Proper hand washing is one of the most effective measures to prevent diarrhoea and respiratory infections, and adequate hand washing with soap and water (running water) is recommended, according to authorities. 2. When should I wash my hands? (1) Before and after transferring documents with others; (2) after coughing or sneezing; (3) Before and after food preparation; (4) Before dinner; (5) Before going to the bathroom; (6) After the hands are dirty; (7) After contact with other persons or animals; (8) After going out. 3. How to wash your hands? (1) Rub the palm with soap or squeeze the hand sanitizer into the palm; (2) Rub the palms of both hands together (rub the palms together about five times); (3) With hands crossed, rub the fingers together (palms of the hands on the back, hands crossed and folded, rub the left and right hands for five times); (4) Palms, palms, heart, scrub fingers (palms are interlacing with ten fingers, scrub five times); (5) Rub the fingertips on the palms with the same left and right hands (put the fingertips on the palms and rub each other for five times); (6) Hold the thumb of the other hand in one hand and rub it with the same hand for five times; (7) Bend the fingers to make the joints rotate and knead in the palm of the other hand, and exchange for five times each; (8) Wash hands with clean water, rinse hands with foam, and then dry hands with clean disposable paper towels or towels. 4. What if you don't have clean water to wash your hands on the way out? If you need to clean your hands on your way out, use an alcohol-based disinfectant.According to the information provided by the relevant department, novel Coronavirus is neither acid nor alkali resistant, and is sensitive to organic solvents and disinfectants. In general, 75% alcohol will eliminate live viruses.So, on the way out, a disinfectant with a certain concentration of alcohol can be a substitute for soap and water. Hand washing has always played an important role in personal protection against coVID-19.So let's hope this has helped us develop a good hand washing habit.

The Difference Between PVC Gloves and PE Gloves Labor gloves can be divided by function or by material.The categories of gloves may vary depending on how you classify them.However, for better hand protection.People need a clearer understanding of labor gloves. So, both belong to transparent gloves, do you know what are the differences between PVC gloves and PE gloves? In fact, even PVC gloves and PE gloves are transparent gloves.However, there are some differences between the two.The most obvious are the following three aspects. 1. Material difference: As the name of the two, PVC gloves are made of PVC paste resin, plasticizer, stabilizer, viscosity reducing agent, PU, softening water as the main production materials, and then through a special process synthesis. And PE gloves are made of low (LDPE), high (HDPE) density polyethylene materials, and other additives refined processing. So, the two feel a little different, PVC gloves will be more elastic, and softness or, on the contrary, PE gloves no matter in elasticity or softness, performance is poor.Not only that, PE gloves have no size and size. 2. Differences in Characteristics: PVC gloves do not contain sensitive source, not only low dust content, ion content is also low, with a certain degree of alkali resistance and elasticity, and the price is relatively low, more convenient to wear. PE gloves also do not contain sensitive sources, transparency is higher than PVC gloves, and gloves more loose openings, more convenient to wear.With the advantages of bright surface color, uniform thickness, light weight, good hand feeling, low price, non-toxic and harmless, it is a commonly used economic hand protection product nowadays. 3. Differences in USES: PVC gloves are often used in electronics, chemical, food and medical industries, and are favored by precision electronics and semiconductor industries. PE gloves are commonly used for household cleaning, sanitation, industrial and agricultural protection, etc., and are more suitable for some simple protective operations. See here, I believe we all know the difference between PVC gloves and PE gloves.I hope the next time you buy transparent gloves, you won't confuse the two.

Classification of Medical Masks and Common Questions in COVID-19 Medical masks play an important role in preventing the spread of the virus during coVID-19. In this regard, Guangzhou Yangyue will be based on the standards of some countries (China, the United States and Europe), with you to explain the classification of medical masks and some common questions, I hope to help you. However, before sharing, I hope you can bear in mind that not all masks are medical masks, and only masks that meet certain standards (such as yy0469-2011 in China) can be called "medical masks". First of all, let's share the classification of medical masks: According to relevant data, in China, medical masks can be divided into three types, namely, medical protective masks with the highest level of protection, medical surgical masks specially used for surgical operations and ordinary medical masks. Here are three differences: The shape of the medical protective mask is generally cup shape, and the common shape is arch and butterfly (as shown in the figure below). Compared with the other two medical masks, it is more consistent with the user's face shape. Moreover, it can filter particles and pollutants in the air (such as droplets, blood, etc.), and the filtering effect of oily particles can reach 95%. Medical surgical masks, common shapes are bind type and ear hook type (as shown in the figure below), is mainly used in the operating room or other body fluids and blood spatter risk exists environment, prevent blood and body fluids through breath area pollution to the wearer, bacteria filtration efficiency more than 95%, conform to the YY0469-2011 standard surgical masks (China standard).But this type of mask isn't as efficient at filtering oily particles as a medical respirator, and it mostly filters rectangular particles that don't fit as well on the wearer's face. More than ordinary surgical masks, is hanging ear type, appearance and hangers type medical surgical masks is similar to (as shown in the figure below), the type of surgical masks, masks have no bearing "protection" and "surgery" and other words, the isolation effect of blood and body fluids, not too big, or sex is not the other two surgical masks closely, commonly used in ordinary medical environment. Finally, share some common questions: 1. What is an N95 mask? A: N95 respirator, one of nine respirators certified by the National Institute of Occupational Safety and Health /NIOSH, also known as dust respirator, is a special labor protection product.In the domestic production of N95 masks, in addition to the production license for industrial products, the manufactured products also need to comply with the national standard GB2626-2006. According to NIOSH 42CFR-84 of the United States, the grade of filter material and filtration efficiency of a mask, N stands for Not resistant to oil.And 95 means that the filtration efficiency of mask is at least 95%. Therefore, the blocking rate of N95 respirator to non-oily aerosol particles is above 95%, and it fits the wearer's face to ensure that air can enter and leave through the respirator. 2. What do N, KN and FFP on the mask represent respectively? A: To put it simply, N on the mask stands for the American standard, KN stands for the Chinese standard, and FFP stands for the European standard. The U.S. Standard is set by the National Institute for Occupational Safety and Health (NIOSH 42CFR-84), which ranks masks according to their filtration performance and the material used to filter them. The European standard is the standard certified by the European Standard Committee for respiratory protection equipment. This standard divides the particulate protection filter material into solid particle protection and liquid particle protection, respectively using NaCL (sodium chloride) and DOP (paraffin oil) aerosol test and classification. According to gb2626-2006, masks are divided into KN class and KP class. KN refers to that masks are suitable for filtering non-oily particles, while KP refers to that masks are suitable for filtering oily and non-oily particles. 3. In the coVID-19 epidemic, are masks with valves more effective? A: Not necessarily, because valved masks can cause a local accumulation of the virus. 4. Do thicker masks have better filtering effect? A: No, because the filtration efficiency of a mask mainly depends on the filtration material of the middle layer, not on the thickness of the mask.The filter material commonly used in masks is melt-sprayed non-woven fabric made of polypropylene superfine fiber, which is not only thin and breathable, but also effective in filtering particulate matter from the air.Of course, the melt-spray non-woven cloth produced by different manufacturers will be different, the specific filtration effects also need professional equipment for testing.However, compared with ordinary needle-punched and spunlaced non-woven fabrics, melt-sprayed non-woven fabrics have better filtering effect. 5. Should we choose the mask with the highest level of protection during coVID-19? A: The choice of mask should be decided according to the surrounding environment, not blindly choose the mask with the highest level of protection.Because, the higher the level of the mask, the higher the price, and because of the high content of filter material, good adhesion and high respiratory resistance, long-term wear, it is easy to have difficulty breathing and other uncomfortable phenomenon. If you are in an environment with high infective content and high risk of transmission, you should try to choose a mask with high protection level.On the contrary, if you are exposed to low levels of infectious agents and in a ventilated environment, you should wear a common respirator. 6. Does wearing two masks provide better protection than wearing one? A: According to relevant studies, the effect of particulate filtration is not significantly different between a single mask and two superimposed masks at low flow rates.At a high flow rate, the filtering effect of the stacked mask is higher than that of the single mask. However, in real life, it is very difficult to reach 80-100 L/min.Therefore, wearing a multi-layer mask, not only will not enhance the protective effect, but will reduce the comfort of wearing. 7. How often should the mask be changed? A: The protective effect of any mask is time-limited, so it is necessary to change masks regularly, even in special times.It is recommended not to reuse the mask and to replace it every 2 to 4 hours. If the mask is contaminated, the mask should be replaced in time. 8. Can I wear a mask all the time? A: Masks are not recommended for long periods of time, as they can easily cause lung damage and can even cause emphysema and other problems. 9. How to dispose of contaminated masks? A: Contaminated masks can be placed in plastic bags and sealed to avoid contact with clothing or other objects, increasing the risk of transmission.Then place the sealed mask in a designated place. Do not throw it away. And when you remove the mask, try to avoid touching the outside of the mask.Wash hands promptly after removing the mask. It has been months since coVID-19 emerged.Although the epidemic at home has been brought under control, the epidemic abroad is still severe.As a result, we are still a long way from taking off our masks.Therefore, we should be ready to play a protracted war, strengthen their awareness of the use of masks.

Is It Appropriate For Children To Wear Adult Masks Under COVID-19 ? Recently, due to the novel Coronavirus epidemic, many clients consulted Guangzhou Yangyue Security and wanted to know more about the knowledge of labor protection masks.Many wanted to know if children could wear adult masks. In this regard, Guangzhou Yang Yue security today for you to explain, on whether children can wear adult masks this issue. The answer, first, is no.If a child wears an adult mask improperly, it may cause respiratory tract damage or suffocation, endangering the health and safety of the child. So why shouldn't children wear adult masks? Guangzhou Yangyue Security thinks that the reasons can be divided into two aspects: 1. Suitability: The masks worn by adults are designed according to the shape of the adult's face.Therefore, compared with children, the mask worn by adults will appear slightly larger, resulting in insufficient tightness and other conditions.In the face of COVID-19, if the mask is not tightly closed, it will be difficult to provide protection. 2. Respiratory resistance: The respirators worn by adults are designed according to the respiratory resistance of adults.Therefore, when children need to wear adult masks, they need to consider their physical conditions. If children have lung diseases or heart diseases, it is easy to cause breathing difficulties and other conditions. So, what should children consider when choosing masks? When selecting masks for children, guardians should consider two aspects, one is the filtering and protection effect of masks, the other is the closeness.The mask you choose must conform to a certain level of protection, and the face shape should also conform to ensure tightness.However, it is also important to pay attention to the age when children wear masks. Children are different from adults. Adults can stop using masks when they feel uncomfortable, but some minors may not be able to judge for themselves.Parents should understand all such risks and ensure the health and safety of minors. Well, the above is all of today's share, I hope to help you, but also need you can choose appropriate masks for their children.

Features and Application Places of Common Masks in the Market There are about five kinds of masks commonly used by users, namely cotton masks, gauze masks, disposable medical masks, KN95 masks and N95 masks. 1. Cotton mask (also known as ordinary mask) These masks are made of cotton cloth, which keeps people warm and filters large particles of dust from the air.However, for some relatively small particles, there is basically no protection, so this type of mask is usually used in dust weather. In addition, because this type of mask is cheaper, we should pay attention to the quality of cotton cloth and avoid buying low-quality cotton masks.It is recommended to go to a regular mask supplier or pharmacy to buy. 2. Gauze mask (also known as defatted gauze mask) As the name suggests, this kind of mask is made by folding and sewing 12~24 layers of defatted yarn, which can block particles through layers of gauze. It has the advantages of cheap, soft, warm, breathable and reusable, etc. However, due to its poor blocking effect on particles, it is often used for general health protection. In addition, when cleaning this type of mask, it is also necessary to pay attention to, and do not rub hard, so as not to damage the gauze, affect the filtering effect on the particles. 3. Disposable medical masks Disposable medical masks are generally made of non-woven cloth and polypropylene fiber melting and spraying materials, divided into outer, middle and inner three layers, composed of mask face body, tension belt and nose bridge clip, play the role of anti-splash, filtration, moisture-proof, and comfortable to wear, can filter particles above PM4.But it does not protect against PM2.5, so it cannot be used in heavily polluted weather. Disposable medical masks are generally used in the medical environment to protect the respiratory safety of medical and related staff and avoid infection from diseases.These masks can also be used for disposable hygiene in ordinary environments or to block particles other than pathogenic microorganisms, such as pollen. 4. KN90 mask KN90 mask is actually a mask conforming to The National standards of China. It can filter MORE than 90% PM2.5 particles and is suitable for non-ferrous metal processing, metallurgy, iron and steel, coking, gas, organic chemical industry, food processing, construction, decoration and petrochemical industries. Although the protective effect is not as good as The N95 and the wearing comfort is relatively better, the breathing will be a little stuffy when wearing it.KN90 is a good choice if it is worn for a short time in the haze weather. 5. N95 mask N95 is a national Institute for Occupational Safety and Health (NIOSH) standard. "N" means "not suitable for oily particulate matter" and "95" means that the NIOSH standard requires a barrier of more than 95 percent for 0.3 micron particles.Therefore, N95 is not a specific product name, but rather a standard. Any mask that meets this standard and passes the NIOSH review can be called 'N95'. Common N95 masks are equipped with a breathing valve, so N95 masks are also known as "piggy mouth masks".This type of mask is commonly used for occupational respiratory protection and is protective against most microbial particles. However, it is important to keep in mind that the N95 is not breathable, comfortable, and breathable, and is not suitable for all users, especially those with respiratory diseases, the elderly, and young children.And everyone's face shape is not the same, so the design of the mask is not entirely suitable for everyone, if the fitting is not enough, it will cause leakage.In addition, N95 masks are not washable and are valid for 40 hours or 1 month, so they are significantly more expensive than other masks.Therefore, consumers should not blindly buy N95 just because it has a good protective effect. The purpose of protection and the special circumstances of users should be fully considered when purchasing N95. At home, the epidemic is slowly under control today, masks are still in short supply, after all, the epidemic abroad is still serious.Therefore, it is important to choose the right mask.I hope the above sharing will be helpful for you to know masks.

How to Wear a Mask Scientifically in Hot Summer ? In this hot summer, because of the coVID-19 outbreak, you have to wear a mask even when it is hot.As a result, many people thought their faces had been "warmed" and were pleased to mention a red rash... In fact, how should we scientifically wear masks in summer to prevent coVID-19 and reduce the problems caused by wearing masks? 1. Choose a suitable elastic mask to reduce the friction and pressure on the skin behind the ear.If you are in a low-risk environment, wear an earless mask, such as a lacing mask. 2. It is recommended not to wear a mask for a long time in summer to avoid respiratory damage.If it is safe to do so, remove the mask appropriately, such as in an open, ventilated outdoor environment or a place with few people. 3. Before wearing the mask, apply emollient to the local area of the face to reduce the friction and irritation of the mask edges on the face. 4. If people have respiratory diseases, especially cardiopulmonary diseases, they should try to avoid wearing masks for a long time in the case of high temperature.If you don't feel well, try to rest at home to reduce the risk of going out. 5. For the general population, there is no significant health risk associated with working at normal temperatures.But, if work in hot weather, metabolism will be faster, easy to appear chest stuffy short phenomenon.It is recommended that masks should not be worn for long periods of time in high temperatures.In case of chest tightness and shortness of breath, should be timely to rest in the shade. 6. Wearing a mask during exercise may pose some health risks.It is recommended not to wear a mask during high temperature and heavy exercise activities. 7. Don't go to crowded places and keep a normal social distance (more than 1.5 meters).
