Silicosis is a permanent disease with no cure. Treatment options currently available focus on alleviating the symptoms and preventing any further progress of the condition. These include:

- Stopping further exposure to airborne silica, silica dust and other lung irritants, including tobacco smoking.

- Cough suppressants.

- Antibiotics for bacterial lung infection.

- TB prophylaxis for those with positive tuberculin skin test or IGRA blood test.

- Prolonged anti-tuberculosis (multi-drug regimen) for those with active TB.

- Chest physiotherapy to help the bronchial drainage of mucus.

- Oxygen administration to treat hypoxemia, if present.

- Bronchodilators to facilitate breathing.

- Lung transplantation to replace the damaged lung tissue is the most effective treatment, but is associated with severe risks of its own.

- For acute silicosis, bronchoalveolar lavage may alleviate symptoms, but does not decrease overall mortality.

Experimental treatments include:

- Inhalation of powdered aluminium, d-penicillamine and polyvinyl pyridine-N-oxide.

- Corticosteroid therapy.

- Chinese Herbal Kombucha

- The herbal extract tetrandrine may slow progression of silicosis.

The following are precautionary measures that can be taken to avoid the spread of bagassosis:

1. Dust control-prevention /suppression of dust such as wet process, enclosed apparatus, exhaust ventilation etc. should be used

2. Personal protection- masks/ respirators

3. Medical control- initial medical examination & periodical checkups of workers

4. Bagasse control- keep moisture content above 20% and spray bagasse with 2% propionic acid

The best way to prevent silicosis is to identify work-place activities that produce respirable crystalline silica dust and then to eliminate or control the dust ("primary prevention"). Water spray is often used where dust emanates. Dust can also be controlled through dry air filtering.

Following observations on industry workers in Lucknow (India), experiments on rats found that jaggery (a traditional sugar) had a preventive action against silicosis.

Asthma is a respiratory disease that can begin or worsen due to exposure at work and is characterized by episodic narrowing of the respiratory tract. Occupational asthma has a variety of causes, including sensitization to a specific substance, causing an allergic response; or a reaction to an irritant that is inhaled in the workplace. Exposure to various substances can also worsen pre-existing asthma. People who work in isocyanate manufacturing, who use latex gloves, or who work in an indoor office environment are at higher risk for occupational asthma than the average US worker. Approximately 2 million people in the US have occupational asthma.

Affected workers should be offered alternative employment. Continued exposure leads to development of persistent symptoms and progressive decline in FEV1.

There is no cure available for asbestosis. Oxygen therapy at home is often necessary to relieve the shortness of breath and correct underlying low blood oxygen levels. Supportive treatment of symptoms includes respiratory physiotherapy to remove secretions from the lungs by postural drainage, chest percussion, and vibration. Nebulized medications may be prescribed in order to loosen secretions or treat underlying chronic obstructive pulmonary disease. Immunization against pneumococcal pneumonia and annual influenza vaccination is administered due to increased sensitivity to the diseases. Those with asbestosis are at increased risk for certain cancers. If the person smokes, quitting the habit reduces further damage. Periodic pulmonary function tests, chest x-rays, and clinical evaluations, including cancer screening/evaluations, are given to detect additional hazards.

Asbestosis is a fibrosing interstitial lung disease caused by exposure to forms of the mineral asbestos.

Infliximab, an immune-suppressing antibody, has been tested in COPD; there was a possibility of harm with no evidence of benefit.

Roflumilast, cilomilast, and phosphodiesterase 4 inhibitors act as a bronchodilator and as an anti-inflammatory. They show promise in decreasing the rate of exacerbations, but do not appear to change a persons quality of life. Roflumilast and cilomilast may be associated with side effects such as gastrointestinal issues and weight loss. Sleep disturbances and mood disturbances related to roflumilast have also been reported.

Several new long-acting agents are under development. Treatment with stem cells is under study. While there is tentative data that it is safe, and the animal data is promising, there is little human data as of 2017. The human data has shown poor results.

A procedure known as target lung denervation, which involves decreasing the parasympathetic nervous system supply of the lungs, is being studied but does not have sufficient data to determine its use. The effectiveness of alpha-1 antitrypsin augmentation treatment for people who have alpha-1 antitrypsin deficiency is unclear.

Research continues into the use of telehealthcare to treat people with COPD when they experience episodes of shortness of breath; treating people remotely may reduce the number of emergency-room visits and improve the person's quality of life.

General treatment principles are removal from exposure, protection of the airway (i.e., preemptive intubation), and treatment of hypoxemia. Concomitant airway injury with acute bronchospasm often warrants treatment with bronchodilators because of the airway obstruction.

A beneficial role for corticosteroids has not been established by controlled trials in humans. Despite the lack of controlled evidence of efficacy, anecdotal reports of benefits from systemic corticosteroid use continue to appear.

Prophylactic antibiotic drugs have not proved to be efficacious in toxic lung injury. Antibiotics should be reserved for those patients with clinical evidence of infection.

Dust pneumonia was featured in the work of several musicians and artists of the day, such as Woody Guthrie's song "Dust Pneumonia Blues".

Feline asthma and other respiratory diseases may be prevented by cat owners by eliminating as many allergens as possible. Allergens that can be found in a cat’s habitual environment include: pollen, molds, dust from cat litter, perfumes, room fresheners, carpet deodorizers, hairspray, aerosol cleaners, cigarette smoke, and some foods. Avoid using cat litters that create lots of dust, scented cat litters or litter additives. Of course eliminating all of these can be very difficult and unnecessary, especially since a cat is only affected by one or two. It can be very challenging to find the allergen that is creating asthmatic symptoms in a particular cat and requires a lot of work on both the owner’s and the veterinarian's part. But just like any disease, the severity of an asthma attack can be propelled by more than just the allergens, common factors include: obesity, stress, parasites and pre-existing heart conditions. Dry air encourages asthma attacks so keep a good humidifier going especially during winter months.

No cure for COPD is known, but the symptoms are treatable and its progression can be delayed. The major goals of management are to reduce risk factors, manage stable COPD, prevent and treat acute exacerbations, and manage associated illnesses. The only measures that have been shown to reduce mortality are smoking cessation and supplemental oxygen. Stopping smoking decreases the risk of death by 18%. Other recommendations include influenza vaccination once a year, pneumococcal vaccination once every five years, and reduction in exposure to environmental air pollution. In those with advanced disease, palliative care may reduce symptoms, with morphine improving the feelings of shortness of breath. Noninvasive ventilation may be used to support breathing. Providing people with a personalized action plan, an educational session, and support for use of their action plan in the event of an exacerbation, reduces the number of hospital visits and encourages early treatment of exacerbations.

Although feline asthma is incurable, ongoing treatments allow many domestic cats to live normal lives. Feline asthma is commonly managed through use of bronchodilators for mild cases, or glucocorticosteroids with bronchodilators for moderate to severe cases.

Previously, standard veterinary practice recommended injected and oral medications for control of the disease. These drugs may have systemic side effects including diabetes and pancreatitis. In 2000, Dr. Philip Padrid pioneered inhaled medications using a pediatric chamber and mask using Flovent(r) (fluticasone) and salbutamol. Inhaled treatments reduce or eliminate systemic effects. In 2003 a chamber called the AeroKat Feline Aerosol Chamber was designed specifically for cats, significantly improving efficiency and reducing cost for the caregiver. Medicine can also be administered using a human baby spacer device. Inhaled steroid usually takes 10-14 days to reach an effective dose.

Byssinosis, also called "brown lung disease" or "Monday fever", is an occupational lung disease caused by exposure to cotton dust in inadequately ventilated working environments. Byssinosis commonly occurs in workers who are employed in yarn and fabric manufacture industries. It is now thought that the cotton dust directly causes the disease and some believe that the causative agents are endotoxins that come from the cell walls of gram-negative bacteria that grow on the cotton. Although bacterial endotoxin is a likely cause, the absence of similar symptoms in workers in other industries exposed to endotoxins makes this uncertain.

Of the 81 byssinosis-related fatalities reported in the United States between 1990 and 1999, 48% included an occupation in the yarn, thread, and fabric industry on the victim's death certificate. This disease often occurred in the times of the industrial revolution. Most commonly young girls working in mills or other textile factories would be afflicted with this disease. In the United States, from 1996 to 2005, North Carolina accounted for about 37% of all deaths caused by byssinosis, with 31, followed by South Carolina (8) and Georgia (7).

The term "brown lung" is a misnomer, as the lungs of affected individuals are not brown.

Coal workers' pneumoconiosis (CWP), also known as black lung disease or black lung, is caused by long exposure to coal dust. It is common in coal miners and others who work with coal. It is similar to both silicosis from inhaling silica dust and to the long-term effects of tobacco smoking. Inhaled coal dust progressively builds up in the lungs and cannot be removed by the body; this leads to inflammation, fibrosis, and in worse cases, necrosis.

Coal workers' pneumoconiosis, severe state, develops after the initial, milder form of the disease known as anthracosis ("anthrac" — coal, carbon). This is often asymptomatic and is found to at least some extent in all urban dwellers due to air pollution. Prolonged exposure to large amounts of coal dust can result in more serious forms of the disease, "simple coal workers' pneumoconiosis" and "complicated coal workers' pneumoconiosis" (or progressive massive fibrosis, or PMF). More commonly, workers exposed to coal dust develop industrial bronchitis, clinically defined as chronic bronchitis (i.e. productive cough for 3 months per year for at least 2 years) associated with workplace dust exposure. The incidence of industrial bronchitis varies with age, job, exposure, and smoking. In nonsmokers (who are less prone to develop bronchitis than smokers), studies of coal miners have shown a 16% to 17% incidence of industrial bronchitis.

In 2013 CWP resulted in 25,000 deaths down from 29,000 deaths in 1990.

Pneumoconiosis is an occupational lung disease and a restrictive lung disease caused by the inhalation of dust, often in mines and from agriculture.

In 2013, it resulted in 260,000 deaths, up from 251,000 deaths in 1990. Of these deaths, 46,000 were due to silicosis, 24,000 due to asbestosis and 25,000 due to coal workers pneumoconiosis.

Recovery is directly dependent on the duration and level of exposure to the causative agent. Depending on the severity of the case, the condition of the patient can improve dramatically during the first year after removal from exposure.

Three basic types of procedures are used for treating the affected workers: reducing a worker's exposure, removing a worker from the environment with the asthma-causing agent, and treatment with asthma medications. Completely stopping exposure is more effective treatment than reducing exposure. By reducing exposure, the probability of suffering another reaction is lowered. Methods of reducing exposure include transferring an affected worker to a position without the relevant asthmagen, use of respiratory protection, and engineering controls. In 1984 innovator David Cornell discovered and invented effective control equipment in the UK for the removal of many harmful workplace fumes. 'BOFA' extraction products are now found in over 100 countries worldwide.

People affected by occupational asthma that occurred after a latency period, whether a few months or years, should be immediately removed from exposure to the causative agent. However, this can entail severe socio-economic consequences for the worker as well as the employer due to loss of job, unemployment, compensation issues, quasi-permanent medical expenditures, and hiring and re-training of new personnel. This can be mitigated by transferring the worker within a company.

Prevention of occupational asthma can be accomplished through better education of workers, management, unions and medical professionals. This will enable them to identify the risk factors and put in place preventive measures, including respiratory protection and exposure limits.

Dust pneumonia describes disorders caused by excessive exposure to dust storms, particularly during the Dust Bowl in the United States. A form of pneumonia, dust pneumonia results when the lungs are filled with dust, inflaming the alveoli.

Symptoms of dust pneumonia include high fever, chest pain, difficulty in breathing, and coughing. With dust pneumonia, dust settles all the way into the alveoli of the lungs, stopping the cilia from moving and preventing the lungs from ever clearing themselves.

People who had dust pneumonia often died. There are no official death rates published for the Great Plains in the 1930s. In 1935, dozens of people died in Kansas from dust pneumonia. Red Cross volunteers made and distributed thousands of dust masks, although some farmers and other people in the affected areas refused to wear them.

Acute exacerbations can be partially prevented. Some infections can be prevented by vaccination against pathogens such as influenza and "Streptococcus pneumoniae". Regular medication use can prevent some COPD exacerbations; long acting beta-adrenoceptor agonists (LABAs), long-acting anticholinergics, inhaled corticosteroids and low-dose theophylline have all been shown to reduce the frequency of COPD exacerbations. Other methods of prevention include:

- Smoking cessation and avoiding dust, passive smoking, and other inhaled irritants

- Yearly influenza and 5-year pneumococcal vaccinations

- Regular exercise, appropriate rest, and healthy nutrition

- Avoiding people currently infected with e.g. cold and influenza

- Maintaining good fluid intake and humidifying the home, in order to help reduce the formation of thick sputum and chest congestion.

Mineral dust airway disease is due to inhaled mineral dust causing fibrosis and narrowing of primarily the respiratory bronchioles. It is distinct from pneumoconiosis which is due to lung tissue fibrosis but shares the same cause.

In 2013 pneumoconiosis resulted in 260,000 deaths up from 251,000 deaths in 1990. Of these deaths 46,000 were due to silicosis, 24,000 due to asbestosis and 25,000 due to coal workers pneumoconiosis.

When eosinophilic pneumonia is related to an illness such as cancer or parasitic infection, treatment of the underlying cause is effective in resolving the lung disease. When due to AEP or CEP, however, treatment with corticosteroids results in a rapid, dramatic resolution of symptoms over the course of one or two days. Either intravenous methylprednisolone or oral prednisone are most commonly used. In AEP, treatment is usually continued for a month after symptoms disappear and the x-ray returns to normal (usually four weeks total). In CEP, treatment is usually continued for three months after symptoms disappear and the x-ray returns to normal (usually four months total). Inhaled steroids such as fluticasone have been used effectively when discontinuation of oral prednisone has resulted in relapse.

Because EP affects the lungs, individuals with EP have difficulty breathing. If enough of the lung is involved, it may not be possible for a person to breathe without support. Non-invasive machines such as a bilevel positive airway pressure machine may be used. Otherwise, placement of a breathing tube into the mouth may be necessary and a ventilator may be used to help the person breathe.

Oxygen therapy should be initiated if there is significantly low blood oxygen. High flow oxygen may be harmful in those with an acute exacerbation of COPD. In the prehospital environment those given high flow O rather than titrating their O saturations to 88% to 92% had worse outcomes.

Eosinophilic pneumonia due to cancer or parasitic infection carries a prognosis related to the underlying illness. AEP and CEP, however, have very little associated mortality as long as intensive care is available and treatment with corticosteroids is given. CEP often relapses when prednisone is discontinued; therefore, some people with CEP require lifelong therapy. Chronic prednisone is associated with many side effects, including increased infections, weakened bones, stomach ulcers, and changes in appearance.
