Last Wednesday,time information Australia announced at the meeting that the use of artificial stone is prohibited from the use of artificial stone. Except for individual states and territories, the ban in most regions will take effect on July 1, 2024.This is the first country in the world to ban artificial stone.

Workers who are processing artificial stones: UNSPLASH

It was announced that this ban was nothing else, because since 2015, a large number of processed artificial stone workers have suffered from irregular pneumoconiosis.

According to a model report from Cutin University, Australia is facing the epidemic disease of silicon lung disease and related lung cancer.This report estimates that about 10,390 Australians suffer from lung cancer in their lives due to their contact with silicon dust.

Especially those who participated in artificial stone processing, since 2015, it is estimated that nearly 580 of the 4,000 celestial stone workers have been diagnosed with pneumoconiosis.The first case of silicon lung death caused by artificial stone was Anthony White, a 36 -year -old Queensland stonemith. He was diagnosed in 2017 and died in March 2019.They are exposed to particularly high -level inhalation of crystal silicon dust (RCS), which is related to many bad health influences.These adverse health effects are not limited to pneumoconiosis, but also lung cancer and autoimmune diseases.

According to a report released by the University of Monash a few months ago, a quarter of workers in the artificial stone countertop industry in Victoria suffer from pneumoconiosis.A new survey in NSW also found that only a part of the diagnosis. NSW's current monitoring system only requires workers to perform X -ray inspection, but X -rays are not as accurate as CT scanning.

And many of the workers in the artificial stone industry are foreign workers, and some still live in Australia illegally. They are worried that they will be expelled from the country or lose their jobs, so they dare not see a doctor.Therefore, how many people who actually get sick due to artificial stone processing are unknown.

In other countries such as the United States, a study found that workers working in the artificial stone manufacturing industry, especially low insurance coverage and Latin immigrant workers who may be unlicensed. They really face serious health risks caused by silicon dust.This may to some extent reflects the situation of the Australian stone -made stone processing industry.

Artificial stone is a material made of natural stone fragments, quartz and other minerals through artificial synthesis processes, mixed with resin and other adhesives.It is equivalent to reorganization of waste stone materials that were originally unused and resource utilization.In addition, natural marble is much more expensive than artificial marble. The use of artificial stones will bring huge profits to the construction and decoration industry.

During the processing of artificial stone, especially when cutting, polishing and polishing artificial stones, extremely fine silicon dust particles will be released.These silicon dust particles are very small, only one percent of a sand particle size, and the naked eyes are invisible.After being inhaled, they can enter the depths of the lungs, leading to lung fibrosis and scar formation.The silicon content in artificial stones is often much higher than natural stone, which makes the silicon dust concentration generated during the processing process higher, increasing the risk of workers' inhalation of silicon dust.

When the human body inhaled the dust containing silicon, these silicon dust particles were deposited in the lungs, causing a chronic inflammatory response in the lung tissue.This leads to fibrosis in the lungs, that is, the formation of scars in the lung tissue.The process of scarization is irreversible, which means that once the lung tissue is damaged, it will no longer return to normal.The current treatment method is to slow down the progress of the disease and relieve symptoms, and cannot repair the scarring lung tissue.Patients with pneumoconiosis are generally mature when they die. In the end, they were stretched alive because they were extremely difficult to breathe.

Isn't it possible to wear high -protection masks to prevent pneumoconiosis, do these workers do not wear masks?Although Australia has health and safety regulations require workers to use appropriate personal protection equipment during processing, the actual abide by these regulations may vary from workplace, training and supervision.In some cases, due to lack of sufficient understanding, appropriate training or poor supervision, workers may not use sufficient protection measures, such as appropriate dust masks and other respiratory protection equipment.

If you want to prevent pneumoconiosis, you must use industrial dust masks. It has a clear division of the respiratory protection standards in the protection level. The KN100 level is the highest protection level in my country. The efficiency is 95%, the minimum is the KN90 level, and the dust resistance rate is only 90%.To prevent pneumoconiosis, you must reduce the ultra -micro -dust that enters the body. Therefore, you must first choose the KN100 -level dust mask.

For workers in processing the artificial stone industry, it is best to use a full -cover dust mask.Half mask and full -cover are two different types of respiratory protection equipment, mainly the main difference is coverage area and protection capacity.Half -cover covers the nose and mouth, and it is suitable for mid -level air pollution environment, while the full cover covers the entire face, including the eyes, and provides more comprehensive protection.

Although the structure of dust -proof masks is simple, it is not easy to use.Choosing the applicable and suitable mask is only the first step of protection. To protect the protection, it must be used correctly. This includes not only wearing according to the instructions to ensure that the position of each wearing is correct., Timely discover signs of failure of the mask, and replace it in time to ensure the greatest protection effect.Therefore, the workers who processing artificial stones are prone to pneumoconiosis, and may also be because some workers have not learned to use the dust mask correctly.

However, there may be a reason that the general factory cannot be equipped with hundreds of high -standard dust masks, so workers can only use cheap medical masks.

CEASERSTONE, a large artificial stone manufacturer, was very disappointed with the ban.Manufacturer spokesman said that the basis for making this decision is unbearable, because only the risk of artificial stone will not eliminate the pneumonia in the workplace.The point is that the ban will not solve the root cause of the increasing incidence of pneumoconiosis: compliance with safety standards and poor law enforcement.

The first Anthony White, who was the first to die due to artificial stones caused by artificial stone, his brother revealed to the media a message. Only a few family -made stone processing companies would solve employees because they did not wear dust masks.Most companies have the minimal punishment to employees who do not comply with the prescribed regulations, and they will not make you put on a mask.

Anyway, the ban on a knife is still a bit ruthless.
