Seeing that the color of carbon black is black, and it is also a chemical, many friends think that carbon black is a dangerous product. In fact, carbon black is not a dangerous product. Although carbon black is not a dangerous product, carbon black still has certain Danger, this article will focus on explaining the dangers of carbon black.
Hazard Classes of Carbon Black
Relevant information shows that the hazard category of carbon black is not listed, so it can be seen that carbon black does not belong to dangerous chemicals. Dangerous chemicals will be specially marked on it, such as: flammable, explosive, toxic, etc. Moreover, there are images showing that the flammable one is a torch, the explosive one is an explosion pattern, and the poisonous one is a skull.
What are the dangers of carbon black?
Hazards of carbon black to human health
The main ways for carbon black to invade the human body are respiratory inhalation, eyes, and skin. Therefore, the harm of carbon black to human health is mainly reflected in these three aspects.
Long-term inhalation of carbon black dust in large quantities through the respiratory tract may eventually cause damage to the lungs. At present, there is no clear medical report to prove that carbon black can cause cancerous results. But can be included as possible carcinogens for humans.
The main symptoms of carbon black damage to the eyes are foreign body irritation and tearing.
Carbon black to the skin is mainly soiling and irritation of the skin.
People who have worked in carbon black manufacturers for a long time must have heard the information that carbon black can cause cancer, and clearly tell everyone that long-term exposure to carbon black and pigment carbon black will not cause cancer. However, long-term exposure to carbon black is still harmful to human health. I hope that everyone can do a good job in personal protection when exposed to carbon black.
Environmental hazards of carbon black
The leakage and exposure of carbon black has not found to cause serious impact or damage to the environment except that it will pollute the surrounding environment. However, there is a wet granulation process in the production process of carbon black, which will cause certain harm to water resources.
About the hazards of carbon black explosion
If a pure carbon black dust environment is formed in a carbon black workplace, it may cause a dust explosion, but the conditions required for a dust explosion are very harsh, and even if the dust explosion environment can be created, it may not necessarily meet the explosion standard.
Carbon black is not flammable, and generally will not be ignited. If it is kept above 300°C for a long time, it may burn slowly without an open flame, and at the same time release carbon monoxide, carbon dioxide or a very small amount of nitrogen and sulfur oxides.
