Occupational disease
Occupational asbestosis
Apr
Cotton dust lung disease is common in countries with a developed textile and fiber industry but poor occupational protection conditions. In Vietnam, cotton dust lung disease is included in the list of 35 occupational diseases covered by insurance and is classified among the common pneumoconiosis diseases.
1. What is occupational cotton dust lung disease?
Cotton dust lung disease is a respiratory condition commonly found in workers in the fiber industry who are frequently exposed to cotton, jute, hemp, flax fibers, etc.
Cotton dust lung disease is different from asbestosis and silicosis because it belongs to the group of extrinsic allergic diseases. However, they are all common occupational lung diseases in countries with a developing textile industry, including Vietnam.
2. Occupations at risk of cotton dust lung disease
Occupations at risk of cotton dust lung disease:
- Exposure to cotton dust during cotton ginning, baling, opening, tearing, carding, blending, roving, spinning, weaving, and fabric production.
- In the flax–hemp, pineapple fiber processing industry, large amounts of dust are generated in softening, carding, and spinning sections.
- Workers producing cotton wadding, cotton fabrics, and other synthetic fibers.
- Workers in the paper manufacturing industry.
- Workers in the watch manufacturing industry.
- Workers in mattress, cushion, pillow, and related product manufacturing.
- Workers producing paper packaging and paper bags.
- Construction-related occupations such as painting, sanding, concrete grinding.
- Some workers in medical cotton processing factories or facilities using recycled cotton may have a higher risk of fever from secondary infections rather than cotton dust lung disease itself.
Workers in these industries are frequently exposed to fiber dust during production or product use. Without proper protection, they may develop occupational cotton dust lung disease.
3. Mechanism and causes of cotton dust lung disease
Cotton dust is considered the primary cause of the disease. It is a type of fibrous plant dust with diverse components, mainly cotton fibers, and other materials such as cotton shells, leaves, stems, soil, and microorganisms. Depending on the environment where cotton is grown, the composition of cotton dust varies.
In experiments and epidemiological investigations, microorganisms in cotton dust are believed to be the main agents causing cotton dust lung disease. However, the exact component triggering the symptoms remains unclear.
Cotton dust lung disease risk assessment tool is an online application designed to evaluate the risk of contracting cotton dust lung disease in the workplace. By answering a series of scored questions, workers can self-assess their condition and determine their level of risk.
4. Symptoms of cotton dust lung disease
Symptoms of cotton dust lung disease progress through 2 stages:
- Early stage: The patient experiences chest tightness and shortness of breath at the end of the workday or after 4–6 hours of work. The symptoms subside within 5–7 days and then reoccur. At this stage, doctors may detect wheezing, and bronchodilators can reduce symptoms. However, chest tightness and shortness of breath recur frequently, especially with continued exposure to cotton dust.
- Later stage: The patient experiences more severe and frequent shortness of breath, along with symptoms such as fever, headache, cough, fatigue, and dry mouth. These symptoms appear and disappear within 3–6 hours. After 10–20 years of working in the cotton industry, the condition may become irreversible and progress to respiratory failure, emphysema, and bronchiectasis.
5. Harmful effects of occupational cotton dust lung disease
Occupational cotton dust lung disease is dangerous and may cause several health issues:
- Poor respiratory condition: wheezing, shortness of breath, dry cough, chest pain, and reduced lung function.
- Reduced overall health: diminished lung capacity affects physical performance and quality of life.
- Lung infections: increased risk of pneumonia and bronchitis.
- Lung cancer: prolonged dust exposure may increase cancer risk.
- Heart failure: studies show increased risk of cardiovascular problems.
Prevention includes minimizing exposure to harmful agents, using protective equipment properly, and following occupational safety regulations.
6. Complications of cotton dust lung disease
Complications may include:
- Pulmonary inflammation: common symptoms include cough, wheezing, shortness of breath, and fever.
- Chronic obstructive pulmonary disease (COPD): may develop without timely diagnosis and treatment.
- Lung cancer: long-term exposure to fiberglass or mineral fibers may increase risk.
- Pleural disease: caused by fiber particles infiltrating tissues surrounding the lungs, leading to inflammation and swelling.
If you suspect symptoms of cotton dust lung disease, seek medical examination and treatment promptly.
7. Protective equipment to prevent cotton dust lung disease
To prevent cotton dust lung disease, workers should use personal protective equipment to protect the respiratory system and minimize exposure:
- Respiratory masks: help filter dust and small particles.
- Safety goggles: protect eyes from dust.
- Protective clothing: prevents direct contact with fiber dust.
- Gloves: protect hands from dust.
- Safety footwear: protects feet from dust and debris.
Ensure proper use and compliance with occupational safety guidelines.
8. Compensation for workers with cotton dust lung disease
In Vietnam, workers with cotton dust lung disease are entitled to compensation under the Law on Social Insurance and related regulations:
- Health insurance coverage for medical treatment related to the disease.
- Social insurance benefits according to regulations.
- Employer compensation if the disease is caused by unsafe materials, tools, or equipment.
- Occupational disease assessment for insurance benefits and financial support.
However, compensation remains challenging, especially in proving disease causation. Prevention through protective equipment and safety compliance remains the most effective approach.
9. Treatment for cotton dust lung disease
- Avoid exposure: prevent further contact with fiber dust and use full protective gear.
- Symptomatic treatment: anti-inflammatory drugs, cough medicine, corticosteroids, and bronchodilators.
- Treat related conditions: asthma, COPD, bronchitis, sinusitis, pneumonia, etc.
- Lifestyle changes: healthy diet, avoid smoking, avoid polluted environments.
- Home care: drink plenty of water, breathing exercises, maintain good health.
10. Prevention of occupational cotton dust lung disease
- Use personal protective equipment (PPE) properly and replace it regularly.
- Dust control systems: effective ventilation, dust extraction, and environmental cleaning.
- Regular workplace cleaning to reduce dust accumulation.
- Employee training on risks and prevention methods.
- Periodic health checkups to detect respiratory diseases early.
- Compliance with occupational safety and chemical safety standards.
11. Employer responsibilities in preventing cotton dust lung disease
Employers must ensure workplace safety:
- Install dust filtration, ventilation, and dust extraction systems, and monitor workplace environment.
- Conduct thorough pre-employment and periodic medical examinations.
- Provide PPE to workers to protect against cotton dust hazards.
- Conduct workplace environmental monitoring and report results regularly to improve working conditions.
Workers should comply with safety regulations and use protective equipment properly.
