Throughout the 20th century, asbestos was used everywhere, considered an ideal material for thermal and electrical insulation, pipe treatment, and construction structures. However, over time, its dark side was revealed – the dangerous impact on human health. Inhalation of asbestos dust can lead to serious diseases such as asbestosis, lung cancer, and mesothelioma. Because of this, attitudes towards asbestos have radically changed, and today the issues of safety and finding alternatives are extremely relevant. ⚠️
What is asbestos?
Asbestos is not a single mineral but a group of six natural minerals that exist in fibrous form. These minerals differ in their chemical composition and physical properties, which affects their applications and level of danger.
Main characteristics of asbestos:
- Fire resistance: Asbestos withstands high temperatures, does not burn, and does not support combustion.
- Thermal insulation: Excellent at retaining heat, preventing its loss.
- Strength: Asbestos fibers are strong in tension, making them useful in composite materials.
- Chemical resistance: Resistant to the action of many chemicals.
- Electrical non-conductivity: Does not conduct electric current.
- Flexibility: Fibers can be flexible and thin, allowing them to be used in various forms.
Types of asbestos and their features
There are six main types of asbestos, divided into two groups: serpentine and amphibole. The most common and commercially significant types include:
- Chrysotile (white asbestos): The most common type, accounting for about 95% of global production. The fibers are long, flexible, and silky. Chrysotile is considered less dangerous than amphibole types but still poses a health risk.
- Amosite (brown asbestos): The second most common type. The fibers are needle-like and stiff. It is considered more dangerous than chrysotile.
- Crocidolite (blue asbestos): The most dangerous type of asbestos. The fibers are thin, needle-like, and very strong. Crocidolite has a high carcinogenic potential.
Table: Types of asbestos and their characteristics
Type of asbestos | Color | Fiber shape | Health hazard | Prevalence | Usage |
Chrysotile | White | Long, flexible | Medium | Highest | Insulation, roofing materials, textiles |
Amosite | Brown | Needle-like, stiff | High | Medium | Cement products, pipe insulation |
Crocidolite | Blue | Thin, needle-like | Very high | Low | Thermal insulation, acid-resistant materials |
Tremolite | White/Grey | Needle-like | High | Low | Contaminant in other minerals |
Anthophyllite | Brown | Needle-like | High | Very low | Insulation, talc |
Actinolite | Green | Needle-like | High | Very low | Contaminant in other minerals |
Where can asbestos be found?
Asbestos occurs naturally all over the world. Although asbestos mining has significantly decreased due to awareness of its dangers, deposits still exist in many countries.
Main countries with asbestos deposits:
- Canada
- Russia
- Kazakhstan
- China
- Zimbabwe
Ukraine also has asbestos deposits, including the well-known Kenzatske deposit.
Typical places where asbestos can be found:
- Old buildings (built before the 1990s): Asbestos was widely used in building materials such as:
- Insulation: Thermal and sound insulation of walls, roofs, pipes.
- Roofing materials: Asbestos-cement slate, tiles.
- Cladding materials: Asbestos-cement panels, floor and wall tiles.
- Fireproof materials: Fire doors, partitions.
- Textile products: Asbestos fabric for curtains, gloves, workwear.
- Industrial facilities:
- Insulation of pipelines and equipment: At power plants, chemical factories, oil refineries.
- Brake pads and friction materials: In cars, trains, industrial equipment (use is limited).
- Laboratory equipment: Asbestos filters, pads.
- Natural sources: In some regions, asbestos may be found in soil and rock formations, posing a risk to people working outdoors or living near deposits.
What is harmful about asbestos? Impact on health
The danger of asbestos lies in its fibers. When materials containing asbestos are disturbed, microscopic fibers are released into the air, which can settle in the lungs when inhaled. Over time, this can lead to serious diseases:
- Asbestosis: A chronic lung disease characterized by scarring of lung tissue, leading to shortness of breath, cough, and chronic fatigue.
- Lung cancer: Asbestos is a proven carcinogen that significantly increases the risk of developing lung cancer, especially in smokers.
- Mesothelioma: A rare and aggressive type of cancer that affects the pleura (the lining of the lungs) or the peritoneum (the lining of the abdominal cavity). Mesothelioma is almost always associated with asbestos exposure.
- Pleurisy: Inflammation of the pleura that can be caused by asbestos.
- Throat and ovarian cancer: There is evidence of a link between asbestos exposure and these types of cancer.
It is important to note that diseases related to asbestos can develop many years (15-40 years) after the first exposure to the mineral. Even short-term but intense exposure to asbestos can be dangerous.
Table: Diseases related to asbestos
Disease | Description | Symptoms | Latency period | Risk |
Asbestosis | Chronic scarring of the lungs | Shortness of breath, cough, fatigue, chest pain | 10-30 years | High in asbestos industry workers |
Lung cancer | Malignant lung tumor | Cough, hemoptysis, chest pain, weight loss | 20-40 years | Especially high in smokers exposed to asbestos |
Mesothelioma | Cancer of the pleura or peritoneum | Chest/abdominal pain, shortness of breath, fluid accumulation | 20-50 years | Almost always associated with asbestos exposure |
Pleurisy | Inflammation of the pleura | Chest pain, shortness of breath | Varies | Can be caused by various factors, including asbestos |
Throat, ovarian cancer | Malignant tumors of the throat and ovaries | Varies, depending on localization | 10+ years | There is a proven link with asbestos exposure |
How to protect yourself from asbestos?
Protection from asbestos is critically important, especially if you work or live in places where it may be present. Key preventive measures:
- Avoid contact: The best way to protect yourself is to avoid exposure to asbestos. If you know or suspect that a material contains asbestos, do not touch it and do not attempt to remove it yourself.
- Consult professionals: Only certified professionals should be engaged for the identification and safe removal of asbestos. They have the necessary equipment and knowledge to perform the work safely.
- Do not disturb asbestos-containing materials: Do not drill, saw, sand, or break asbestos-containing materials, as this releases dangerous fibers into the air.
- Use personal protective equipment (PPE): If avoiding contact is not possible, it is necessary to use:
- Respirators: Special P3 or N100 respirators capable of filtering asbestos fibers.
- Protective clothing: Disposable coveralls that cover the entire body, gloves, safety goggles.
- Wet cleaning: When working with asbestos, use wet cleaning to prevent dust from spreading. Do not use regular vacuum cleaners, only specialized HEPA vacuums.
- Information and training: Raise awareness about the dangers of asbestos among workers and the public. Conduct training on safe methods of working with asbestos.
Legislation on asbestos in Ukraine and worldwide
Recognizing the deadly danger of asbestos, many countries around the world have implemented strict legislative restrictions or a complete ban on its use.
A complete ban on asbestos is in effect in over 60 countries worldwide, including:
- European Union countries: EU Directive 1999/77/EC prohibits the use of all types of asbestos.
- Australia
- Japan
- Argentina
In Ukraine, the situation is more complicated. There is no complete ban on asbestos, although there are restrictions on the use of amphibole types (crocidolite and amosite). The use of chrysotile asbestos is allowed but regulated by hygiene standards and safety requirements.
Main legislative acts in Ukraine regulating the use of asbestos:
- State sanitary norms and rules “Hygienic classification of labor by indicators of harmfulness and danger of production environment factors, severity and intensity of labor process” (DSN 3.3.5.042-99): Establish hygienic standards for asbestos in workplaces.
- Sanitary norms and rules “Anti-epidemic measures when working with asbestos and asbestos-containing materials” (DSP 9.9.5-080-2002): Regulate safety requirements when working with asbestos.
However, Ukrainian legislation needs further improvement and a complete ban on the use of asbestos, as has been done in many developed countries. It is necessary to strengthen control over the import and use of asbestos, as well as to enhance educational work among the population regarding the dangers of this material.
