Haigu Security | Prevent inhaling dust and protect personal health!
Your health depends to a certain extent on the cleanliness of the air you inhale. In the industrial environment, there are many risk factors, and the hazard of dust has to be mentioned.
What is dust?
Dust hazard to human body
What is dust?
Dust refers to the particle size less than 75 suspended in the air μ M solid particles are everywhere in life and production environment. Productive dust is the natural enemy of workers' health, such as coal dust
Asbestos, welding fume, graphite dust, etc. The smaller the particles, the longer they stay in the air, and the greater the possibility of being inhaled.
Productive dust is a solid particle formed during industrial production and can be suspended in the air of production environment for a long time, which is also the main cause of pneumoconiosis. Its sources are as follows:
Ore crushing, screening, packaging, transportation, batching, mixing and processing of powdery materials, as well as mining, rock drilling, blasting, road construction, etc. In these production processes, such as dust-proof equipment
If the application is not sound, a large amount of dust may escape.
How to protect human body in dust environment?
How to protect human body in dust environment?
If you work in a dust environment, the human body will use these four parts for dust protection.
① Nose hair: help catch large particles of dust
② Mucous layer: can stick the dust entering the trachea
③ Ciliary: push mucus out of the respiratory tract
④ Cough: accelerate mucus excretion
But at the same time, the harmful substances accompanied by dust will also be absorbed in different degrees by the nasal cavity, cilia, mucous membrane or lungs, which will accumulate for a long time and cause damage to the body.
Dust hazard to human body
The higher the dust concentration and the smaller the dust particles, the greater the harm to human body. Long-term work in the environment with high concentration of dust can cause the following diseases:
1. Pneumoconiosis is the most harmful to human body. Such as silicosis, asbestosis, foundry pneumoconiosis, talc pneumoconiosis, etc., the patient's lung function is damaged, and the pneumoconiosis disease is difficult to cure, and serious cases can lead to death.
2. Respiratory diseases. The dust acts on the respiratory mucosa and causes rhinitis, pharyngitis, tracheitis, bronchitis, bronchial asthma, cotton dust disease, etc.
3. Occupational tumor. Asbestos dust causes lung cancer, mesothelioma, and lung cancer in chromate manufacturing workers.
4. Poisoning. Inhalation of lead, arsenic, manganese and other toxic dust can cause lead poisoning, arsenic poisoning, manganese poisoning, etc.
5. Skin diseases. Dust on the skin can cause acne, folliculitis, pyoderma, etc. Asphalt dust can cause allergic dermatitis under sunlight
From this point of view, productive dust is very harmful to human body, but as long as dust protection is well done, the harm of dust to human body can be reduced or avoided.
Select appropriate protective equipment
Dust mask: suitable for protecting dust, smoke, fog and other particles in the workplace.
We usually classify dust (particulate matter) into oily and non-oily. According to the nature of the particles to be protected, GB2626-2019 Respiratory Protection Self-priming Filtration Type Particulate Matter Respirator
The quality of respirators is divided into KN and KP. KN is a non-oil particle respirator, and KP is an oil particle respirator. The standard classifies masks into
90 (KN90, KP90), 95 (KN95, KP95) and 100 (KN100, KP100).
The filtration efficiency refers to the percentage of particles filtered by the filter element of the respirator. For example, the mask is marked with KN95, which means that it can filter at least 95.0% of 0.075um non-oil particles,
The label is KP90, that is, it can filter at least 90.0% of 0.075um oily particles. It should be noted that the filter efficiency of the respirator with a filter efficiency of 100 is not less than 99.97%.
Half-face protective mask: according to the different filter elements selected, it can not only protect against the respiratory hazards of dust, smoke, fog and other particles, but also protect against harmful gases or vapors.
Full-type protective mask: it can provide combined protection of face, eyes and breathing. In terms of respiratory protection, it can protect dust, smoke, fog and other particles according to the different filter elements selected
Inhibit hazards and protect against harmful gases or vapors.
Workers working in the environment of dust and chemical harmful factors must do a good job of respiratory protection, and select appropriate protective equipment, so as to effectively prevent occupational disease hazards, work safely, and be healthy
Healthy life!
